+Preamble: referenced user accounts
+----------------------------------
+
+In subsequent sections, we will refer to a number of different accounts, as
+follows:
+
+ * Linux user accounts:
+ ** The *user* Linux account is the account that you use to log onto the
+ Linux system as a regular user.
+ ** The *root* Linux account is an account that has system administrator
+ privileges. On Debian and Fedora you can switch to this account from
+ your *user* account by issuing the `su -` command and entering the
+ password for the *root* account when prompted. On Ubuntu you can switch
+ to this account from your *user* account using the `sudo su -` command
+ and entering the password for your *user* account when prompted.
+ ** The *opensrf* Linux account is an account that you create when installing
+ OpenSRF. You can switch to this account from the *root* account by
+ issuing the `su - opensrf` command.
+ ** The *postgres* Linux account is created automatically when you install
+ the PostgreSQL database server. You can switch to this account from the
+ *root* account by issuing the `su - postgres` command.
+ * PostgreSQL user accounts:
+ ** The *evergreen* PostgreSQL account is a superuser account that you will
+ create to connect to the PostgreSQL database server.
+ * Evergreen administrator account:
+ ** The *egadmin* Evergreen account is an administrator account for
+ Evergreen that you will use to test connectivity and configure your
+ Evergreen instance.
+
+Preamble: developer instructions
+--------------------------------
+
+[NOTE]
+Skip this section if you are using an official release tarball downloaded
+from http://evergreen-ils.org/downloads
+
+Developers working directly with the source code from the Git repository,
+rather than an official release tarball, must install some extra packages
+and perform one step before they can proceed with the `./configure` step.
+
+As the *root* Linux account, install the following packages:
+
+ * autoconf
+ * automake
+ * libtool
+
+As the *user* Linux account, issue the following command in the Evergreen
+source directory to generate the configure script and Makefiles:
+
+[source, bash]
+------------------------------------------------------------------------------
+autoreconf -i
+------------------------------------------------------------------------------
+
+After running `make install`, developers also need to install the Dojo Toolkit
+set of JavaScript libraries. The appropriate version of Dojo is included
+in Evergreen release tarballs. Developers should install the Dojo 1.3.3
+version of Dojo by issuing the following commands as the *opensrf* Linux
+account:
+
+[source, bash]
+------------------------------------------------------------------------------
+wget http://download.dojotoolkit.org/release-1.3.3/dojo-release-1.3.3.tar.gz
+tar -C /openils/var/web/js -xzf dojo-release-1.3.3.tar.gz
+cp -r /openils/var/web/js/dojo-release-1.3.3/* /openils/var/web/js/dojo/.
+------------------------------------------------------------------------------
+
+Installing prerequisites
+------------------------
+
+Evergreen has a number of prerequisite packages that must be installed
+before you can successfully configure, compile, and install Evergreen.
+
+1. Begin by installing the most recent version of OpenSRF (2.1 or later).
+ You can download OpenSRF releases from http://evergreen-ils.org/opensrf.php
+2. On many distributions, it is necessary to install PostgreSQL 9 from external
+ repositories.
++
+ * On Debian Squeeze, open `/etc/apt/sources.list` in a text editor as the
+ *root* Linux account and add the following line:
++
+[source, bash]
+------------------------------------------------------------------------------
+deb http://backports.debian.org/debian-backports squeeze-backports main contrib
+------------------------------------------------------------------------------
++
+ * On Ubuntu Lucid, you can use a PPA (personal package archive), which are
+ package sources hosted on Launchpad. The one most commonly used by Evergreen
+ Community members is maintained by Martin Pitt, who also maintains the
+ official PostgreSQL packages for Ubuntu. As the *root* Linux account, issue
+ the following commands to add the PPA source:
++
+[source, bash]
+------------------------------------------------------------------------------
+apt-get install python-software-properties
+add-apt-repository ppa:pitti/postgresql
+------------------------------------------------------------------------------
++
+ * Ubuntu Precise comes with PostgreSQL 9, so no additional steps are required.
++
+ * Fedora comes with PostgreSQL 9, so no additional steps are required.
++
+3. On Debian and Ubuntu, run `aptitude update` as the *root* Linux account to
+ retrieve the new packages from the backports repository.
+4. Issue the following commands as the *root* Linux account to install
+ prerequisites using the `Makefile.install` prerequisite installer,
+ substituting `debian-squeeze`, `fedora`, `ubuntu-lucid`, or
+ `ubuntu-precise` for <osname> below:
++
+[source, bash]
+------------------------------------------------------------------------------
+make -f Open-ILS/src/extras/Makefile.install <osname>
+------------------------------------------------------------------------------
++
+5. Add the libdbi-libdbd libraries to the system dynamic library path by
+ issuing the following commands as the *root* Linux account:
++
+[NOTE]
+You should skip this step if installing on Ubuntu Precise. The ubuntu-precise
+target uses libdbd-pgsql from packages.
++
+.Debian / Ubuntu Lucid
+[source, bash]
+------------------------------------------------------------------------------
+echo "/usr/local/lib/dbd" > /etc/ld.so.conf.d/eg.conf
+ldconfig
+------------------------------------------------------------------------------
++
+.Fedora
+[source, bash]
+------------------------------------------------------------------------------
+echo "/usr/lib64/dbd" > /etc/ld.so.conf.d/eg.conf
+ldconfig
+------------------------------------------------------------------------------
+
+Configuration and compilation instructions
+------------------------------------------
+
+For the time being, we are still installing everything in the `/openils/`
+directory. From the Evergreen source directory, issue the following commands as
+the *user* Linux account to configure and build Evergreen:
+
+[source, bash]
+------------------------------------------------------------------------------
+./configure --prefix=/openils --sysconfdir=/openils/conf
+make
+------------------------------------------------------------------------------
+
+Installation instructions
+-------------------------
+
+1. Once you have configured and compiled Evergreen, issue the following
+ command as the *root* Linux account to install Evergreen, build the server
+ portion of the staff client, and copy example configuration files to
+ `/openils/conf`.
+ Change the value of the `STAFF_CLIENT_STAMP_ID` variable to match the version
+ of the staff client that you will use to connect to the Evergreen server.
++
+[source, bash]
+------------------------------------------------------------------------------
+make STAFF_CLIENT_STAMP_ID=rel_2_3_0 install
+------------------------------------------------------------------------------
++
+2. The server portion of the staff client expects `http://hostname/xul/server`
+ to resolve. Issue the following commands as the *root* Linux account to
+ create a symbolic link pointing to the `server` subdirectory of the server
+ portion of the staff client that we just built using the staff client ID
+ 'rel_name':
++
+[source, bash]
+------------------------------------------------------------------------------
+cd /openils/var/web/xul
+ln -sf rel_name/server server
+------------------------------------------------------------------------------
+
+Change ownership of the Evergreen files
+---------------------------------------
+
+All files in the `/openils/` directory and subdirectories must be owned by the
+`opensrf` user. Issue the following command as the *root* Linux account to
+change the ownership on the files:
+
+[source, bash]
+------------------------------------------------------------------------------
+chown -R opensrf:opensrf /openils
+------------------------------------------------------------------------------
+
+Configure the Apache Web server
+-------------------------------
+
+1. Use the example configuration files in `Open-ILS/examples/apache/` to
+configure your Web server for the Evergreen catalog, staff client, Web
+services, and administration interfaces. Issue the following commands as the
+*root* Linux account:
++
+.Debian and Ubuntu
+[source,bash]
+------------------------------------------------------------------------------
+cp Open-ILS/examples/apache/eg.conf /etc/apache2/sites-available/
+cp Open-ILS/examples/apache/eg_vhost.conf /etc/apache2/
+cp Open-ILS/examples/apache/startup.pl /etc/apache2/
+# Now set up SSL
+mkdir /etc/apache2/ssl
+cd /etc/apache2/ssl
+------------------------------------------------------------------------------
++
+.Fedora
+[source,bash]
+------------------------------------------------------------------------------
+cp Open-ILS/examples/apache/eg.conf /etc/httpd/conf.d/
+cp Open-ILS/examples/apache/eg_vhost.conf /etc/httpd/
+cp Open-ILS/examples/apache/startup.pl /etc/httpd/
+# Now set up SSL
+mkdir /etc/httpd/ssl
+cd /etc/httpd/ssl
+------------------------------------------------------------------------------
++
+2. The `openssl` command cuts a new SSL key for your Apache server. For a
+production server, you should purchase a signed SSL certificate, but you can
+just use a self-signed certificate and accept the warnings in the staff client
+and browser during testing and development. Create an SSL key for the Apache
+server by issuing the following command as the *root* Linux account:
++
+[source,bash]
+------------------------------------------------------------------------------
+openssl req -new -x509 -days 365 -nodes -out server.crt -keyout server.key
+------------------------------------------------------------------------------
++
+3. As the *root* Linux account, edit the `eg.conf` file that you copied into
+place.
+ a. Replace `Allow from 10.0.0.0/8` with `Allow from all` (to enable
+ access to the offline upload / execute interface from any workstation on
+ any network - note that you must secure this for a production instance)
+ b. (Fedora): Change references from the non-existent `/etc/apache2/` directory
+ to `/etc/httpd/`.
+4. Change the user for the Apache server.
+ * (Debian and Ubuntu): As the *root* Linux account, edit
+ `/etc/apache2/envvars`. Change `export APACHE_RUN_USER=www-data` to
+ `export APACHE_RUN_USER=opensrf`.
+ * (Fedora): As the *root* Linux account , edit `/etc/httpd/conf/httpd.conf`.
+ Change `User apache` to `User opensrf`.
+5. Configure Apache with performance settings appropriate for Evergreen:
+ * (Debian and Ubuntu): As the *root* Linux account, edit
+ `/etc/apache2/apache2.conf`:
+ * (Fedora): As the *root* Linux account, edit `/etc/httpd/conf/httpd.conf`:
+ a. Change `KeepAliveTimeout` to `1`. Higher values reduce the chance of
+ a request timing out unexpectedly, but increase the risk of using up
+ all available Apache child processes.
+ b. 'Optional': Change `MaxKeepAliveRequests` to `100`
+ c. Update the prefork configuration section to suit your environment. The
+ following settings apply to a busy system:
++
+[source,bash]
+------------------------------------------------------------------------------
+<IfModule mpm_prefork_module>
+ StartServers 20
+ MinSpareServers 5
+ MaxSpareServers 15
+ MaxClients 150
+ MaxRequestsPerChild 10000
+</IfModule>
+------------------------------------------------------------------------------
++
+6. (Fedora): As the *root* Linux account, edit the `/etc/httpd/eg_vhost.conf`
+ file to change references from the non-existent `/etc/apache2/` directory
+ to `/etc/httpd/`.
+7. (Debian and Ubuntu): As the *root* Linux account, enable the Evergreen site:
++
+[source,bash]
+------------------------------------------------------------------------------
+a2dissite default # OPTIONAL: disable the default site (the "It Works" page)
+a2ensite eg.conf
+------------------------------------------------------------------------------
+
+Configure OpenSRF for the Evergreen application
+-----------------------------------------------
+There are a number of example OpenSRF configuration files in `/openils/conf/`
+that you can use as a template for your Evergreen installation. Issue the
+following commands as the *opensrf* Linux account:
+
+[source, bash]
+------------------------------------------------------------------------------
+cp -b /openils/conf/opensrf_core.xml.example /openils/conf/opensrf_core.xml
+cp -b /openils/conf/opensrf.xml.example /openils/conf/opensrf.xml
+------------------------------------------------------------------------------
+
+When you installed OpenSRF, you created four Jabber users on two
+separate domains and edited the `opensrf_core.xml` file accordingly. Please
+refer back to the OpenSRF README and, as the *opensrf* Linux account, edit the
+Evergreen version of the `opensrf_core.xml` file using the same Jabber users
+and domains as you used while installing and testing OpenSRF.
+
+[NOTE]
+The `-b` flag tells the `cp` command to create a backup version of the
+destination file. The backup version of the destination file has a tilde (`~`)
+appended to the file name, so if you have forgotten the Jabber users and
+domains, you can retrieve the settings from the backup version of the files.
+
+`eg_db_config.pl`, described in the following section, sets the database
+connection information in `opensrf.xml` for you.
+
+Creating the Evergreen database
+-------------------------------
+
+By default, the `Makefile.install` prerequisite installer does not install
+the PostgreSQL 9 database server required by every Evergreen system;
+for production use, most libraries install the PostgreSQL database server on a
+dedicated machine. You can install the packages required by Debian or Ubuntu Lucid
+on the machine of your choice using the following commands as the *root*
+Linux account:
+
+.(Debian and Ubuntu Lucid) Installing PostgreSQL 9.1 server packages
+[source, bash]
+------------------------------------------------------------------------------
+make -f Open-ILS/src/extras/Makefile.install install_pgsql_server_backport_debs_91
+------------------------------------------------------------------------------
+
+.(Ubuntu Precise) Installing PostgreSQL 9.1 server packages
+[source, bash]
+------------------------------------------------------------------------------
+make -f Open-ILS/src/extras/Makefile.install install_pgsql_server_debs_91
+------------------------------------------------------------------------------
+
+You can install the packages required by Fedora on the machine of your choice
+using the following commands as the *root* Linux account:
+
+.(Fedora) Installing PostgreSQL server packages
+[source, bash]
+------------------------------------------------------------------------------
+make -f Open-ILS/src/extras/Makefile.install install_fedora_pgsql_server
+postgresql-setup initdb
+------------------------------------------------------------------------------
+
+For a standalone PostgreSQL server, install the following Perl modules as the
+*root* Linux account:
+
+.(Debian / Ubuntu) Installing additional Perl modules on a standalone PostgreSQL 9 server
+[source, bash]
+------------------------------------------------------------------------------
+aptitude install gcc libxml-libxml-perl libxml-libxslt-perl
+cpan Business::ISBN
+cpan JSON::XS
+cpan Library::CallNumber::LC
+cpan MARC::Record
+cpan MARC::File::XML
+cpan UUID::Tiny
+------------------------------------------------------------------------------
+
+.(Fedora) Installing additional Perl modules on a standalone PostgreSQL 9 server
+[source, bash]
+------------------------------------------------------------------------------
+yum install gcc perl-XML-LibXML perl-XML-LibXSLT perl-Business-ISBN
+cpan Library::CallNumber::LC
+cpan MARC::Record
+cpan MARC::File::XML
+cpan UUID::Tiny
+------------------------------------------------------------------------------
+
+You need to create a PostgreSQL superuser to create and access the database.
+Issue the following command as the *postgres* Linux account to create a new
+PostgreSQL superuser named `evergreen`. When prompted, enter the new user's
+password:
+
+[source, bash]
+------------------------------------------------------------------------------
+createuser -s -P evergreen
+------------------------------------------------------------------------------
+
+Once you have created the *evergreen* PostgreSQL account, you also need to
+create the database and schema, and configure your configuration files to point
+at the database server. Issue the following command as the *root* Linux account
+from inside the Evergreen source directory, replacing <user>, <password>,
+<hostname>, <port>, and <dbname> with the appropriate values for your
+PostgreSQL database (where <user> and <password> are for the *evergreen*
+PostgreSQL account you just created), and replace <admin-user> and <admin-pass>
+with the values you want for the *egadmin* Evergreen administrator account:
+
+[source, bash]
+------------------------------------------------------------------------------
+perl Open-ILS/src/support-scripts/eg_db_config.pl --update-config \
+ --service all --create-database --create-schema --create-offline \
+ --user <user> --password <password> --hostname <hostname> --port <port> \
+ --database <dbname> --admin-user <admin-user> --admin-pass <admin-pass>
+------------------------------------------------------------------------------
+
+This creates the database and schema and configures all of the services in
+your `/openils/conf/opensrf.xml` configuration file to point to that database.
+It also creates the configuration files required by the Evergreen `cgi-bin`
+administration scripts, and sets the user name and password for the *egadmin*
+Evergreen administrator account to your requested values.
+
+Creating the database on a remote server
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+In a production instance of Evergreen, your PostgreSQL server should be
+installed on a dedicated server.
+
+PostgreSQL 9.1 and later
+^^^^^^^^^^^^^^^^^^^^^^^^
+To create the database instance on a remote database server running PostgreSQL
+9.1 or later, simply use the `--create-database` flag on `eg_db_config.pl`.
+
+For PostgreSQL 9.0
+^^^^^^^^^^^^^^^^^^
+To create the database instance on a remote database server running PostgreSQL
+9.0, you can either:
+
+ * Install the PostgreSQL contrib modules on the machine on which you
+ are installing the Evergreen code, and use the `--create-database`
+ option from that machine, or
+ * Copy the `Open-ILS/src/sql/Pg/create_database.sql` script to your
+ PostgreSQL server and invoke it as the *postgres* Linux account:
++
+[source, bash]
+------------------------------------------------------------------------------
+psql -vdb_name=<dbname> -vcontrib_dir=`pg_config --sharedir`/contrib -f create_database.sql
+------------------------------------------------------------------------------
+
+Then you can issue the `eg_db_config.pl` command as above _without_ the
+`--create-database` argument to create your schema and configure your
+configuration files.
+
+Starting Evergreen
+------------------
+1. As the *root* Linux account, start the `memcached` and `ejabberd` services
+(if they aren't already running):
++
+[source, bash]
+------------------------------------------------------------------------------
+/etc/init.d/ejabberd start
+/etc/init.d/memcached start
+------------------------------------------------------------------------------
++
+2. As the *opensrf* Linux account, start Evergreen. The `-l` flag in the
+following command is only necessary if you want to force Evergreen to treat the
+hostname as `localhost`; if you configured `opensrf.xml` using the real
+hostname of your machine as returned by `perl -ENet::Domain 'print
+Net::Domain::hostfqdn() . "\n";'`, you should not use the `-l` flag.
++
+[source, bash]
+------------------------------------------------------------------------------
+osrf_ctl.sh -l -a start_all
+------------------------------------------------------------------------------
++
+ ** If you receive the error message `bash: osrf_ctl.sh: command not found`,
+ then your environment variable `PATH` does not include the `/openils/bin`
+ directory; this should have been set in the *opensrf* Linux account's
+ `.bashrc` configuration file. To manually set the `PATH` variable, edit the
+ configuration file `~/.bashrc` as the *opensrf* Linux account and add the
+ following line:
++
+[source, bash]
+------------------------------------------------------------------------------
+export PATH=$PATH:/openils/bin
+------------------------------------------------------------------------------
++
+3. As the *opensrf* Linux account, generate the Web files needed by the staff
+ client and catalogue and update the organization unit proximity (you need to do
+ this the first time you start Evergreen, and after that each time you change
+ the library hierarchy in `config.cgi`):
++
+[source, bash]
+------------------------------------------------------------------------------
+autogen.sh -u
+------------------------------------------------------------------------------
++
+4. As the *root* Linux account, restart the Apache Web server:
++
+[source, bash]
+------------------------------------------------------------------------------
+/etc/init.d/apache2 restart
+------------------------------------------------------------------------------
++
+If the Apache Web server was running when you started the OpenSRF services, you
+might not be able to successfully log in to the OPAC or staff client until the
+Apache Web server is restarted.
+
+Testing connections to Evergreen
+--------------------------------
+
+Once you have installed and started Evergreen, test your connection to
+Evergreen via `srfsh`. As the *opensrf* Linux account, issue the following
+commands to start `srfsh` and try to log onto the Evergreen server using the
+*egadmin* Evergreen administrator user name and password that you set using the
+`eg_db_config.pl` command:
+
+[source, bash]
+------------------------------------------------------------------------------
+/openils/bin/srfsh
+srfsh% login <admin-user> <admin-pass>
+------------------------------------------------------------------------------
+
+You should see a result like:
+
+ Received Data: "250bf1518c7527a03249858687714376"
+ ------------------------------------
+ Request Completed Successfully
+ Request Time in seconds: 0.045286
+ ------------------------------------
+
+ Received Data: {
+ "ilsevent":0,
+ "textcode":"SUCCESS",
+ "desc":" ",
+ "pid":21616,
+ "stacktrace":"oils_auth.c:304",
+ "payload":{
+ "authtoken":"e5f9827cc0f93b503a1cc66bee6bdd1a",
+ "authtime":420
+ }
+
+ }
+
+ ------------------------------------
+ Request Completed Successfully
+ Request Time in seconds: 1.336568
+ ------------------------------------
+
+If this does not work, it's time to do some troubleshooting.
+
+ * As the *opensrf* Linux acccount, run the `settings-tester.pl` script to see
+ if it finds any system configuration problems. The script is found at
+ `Open-ILS/src/support-scripts/settings-tester.pl` in the Evergreen source
+ tree.
+ * Follow the steps in the http://evergreen-ils.org/dokuwiki/doku.php?id=troubleshooting:checking_for_errors[troubleshooting guide].
+ * If you have faithfully followed the entire set of installation steps
+ listed here, you are probably extremely close to a working system.
+ Gather your configuration files and log files and contact the
+ http://open-ils.org/listserv.php[Evergreen development mailing list]
+ for assistance before making any drastic changes to your system
+ configuration.
