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.  

    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.  

    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: 

    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.

    1. 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)
    2. (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:

      1. 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.
      2. Optional: Change MaxKeepAliveRequests to 100

      3. Update the prefork configuration section to suit your environment. The following settings apply to a busy system: 

        <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: 

    a2dissite default  # OPTIONAL: disable the default site (the "It Works" page)
a2ensite eg.conf
