Apache Solr on mirabal.mayfirst.org
Apache Solr is an indexing and searching program that can replace the Drupal core search engine with a much improved system.
mirabal.mayfirst.org is a dedicated Apache Solr Server that is available for use by any May First/People Link member.
Web site Administrators
If you run a Drupal web site, you can use Solr. The first step is to determine if you primary host is connected to our Solr server. The following hosts are currently connected:
- lucy.mayfirst.org
If your primary server is not listed, please open a ticket or contact the support team to request having your primary host added.
Once your host is solr-enabled then you can then connect to the Apache Solr server with:
Solr host name: localhost Solr port: 9080 Solr path: /solr/<sitename>
Administrators
Below are the steps administrators must take to provide solr access.
On the primary server
Create a new user on the server and add mirabal's public ssh key to the new user's ./ssh/authorized_keys file. mirabal will connect to the host server and provide an ssh tunnel to the Apache Solr server.
On Mirabal
There are two things to do on mirabal.mayfirst.org: add a ssh tunnel to the host server and create a new Apache Solr site in Apache Tomcat.
Create SSH tunnel
To add a SSH tunnel simply add the login credentials to
/etc/default/solr-autossh
Restart the script with
service solr-autossh restart
Test SSH tunnel
Check with
service solr-autossh status
that the tunnel exists.
Log into the server running the website (as solr user) and download with
wget localhost:9080
the Apache Tomcat welcome page from mirabal.mayfirst.org.
Create new Solr configuration
Copy the configuration directory
cp -a /etc/solr/conf /etc/solr/<sitename>/conf
If you need a different configuration than Apache Solr Drupal you probably have to change at least schema.xml and solrconfig.xml.
Create new Solr site
Copy an existing Solr core
cp -a /usr/share/solr/testsite /usr/share/solr/<sitename>
Change the symbolic link to the new configuration directory
ln -sf /etc/solr/<sitename>/conf /usr/share/solr/<sitename>/conf
Create a new data directory
mkdir /var/lib/solr/data/<sitename>
Change ownership to tomcat6
chown -R tomcat6:tomcat6 /var/lib/solr/data
Change the symbolic link to the new data directory
ln -sf /var/lib/solr/data/<sitename> /usr/share/solr/<sitename>/data
Create new Solr core
Add a new core
<core name="<sitename>" instanceDir="<sitename>" />
to Apache Solr
/etc/solr/solr-multicore.xml
Restart Apache Tomcat
Restart Apache Tomcat with
service tomcat6 restart
Test new Solr site
Check that the new core is accessible at
http://localhost:8080/solr/<sitename>/admin
