At the recently Drupal Camp Prague 09, I was introduced to ApacheSolr as a replacement to the standard Drupal search or the Google CSE.
On most sites the basic Google CSE setup is sufficient, however for some of the more serious "work" websites my colleague Nick and I got experimenting with the Drupal's implementation of ApacheSolr module.
Here is a quick and rough writeup on how it was implemented on work and my personal (janaksingh.com website).
Please feel free to share your experiences and tips.
Basic Installation
1) Install Java on CentOS if you havent already
2) Install ApacheSolr drupal module
cvs -z6 -d:pserver:anonymous:anonymous@cvs.drupal.org:/cvs/drupal-contrib checkout -d apachesolr -r DRUPAL-6--2 contributions/modules/apachesolr/
3) Checkout the ApacheSolr PHP Lib inside the ApacheSolr module folder
svn checkout -r22 http://solr-php-client.googlecode.com/svn/trunk/ SolrPhpClient
4) Create a temp folder in your home directory
cd ~ mkdir temp cd temp
5) Download ApacheSolr in the temp folder
SVN Method
svn checkout http://svn.apache.org/repos/asf/lucene/solr/branches/branch-1.4 apache-solr
TAR Method
Grab the tarball from http://www.apache.org/dyn/closer.cgi/lucene/solr/
wget http://mirrors.ukfast.co.uk/sites/ftp.apache.org/lucene/solr/1.4.0/apache-solr-1.4.0.zip
tar -xzf apache-solr-1.4.0.zip mv apache-solr-1.4.0 apache-solr
I have moved my "apache-solr" folder to "/usr/local/share/" but I am not sure if this matters
6) Rename 2 default files in apache-solr/example/solr/conf/
sudo mv solrconfig.xml solrconfig.bak sudo mv schema.xml schema.bak
7) Copy the schema.xml and solrconfig.xml from the drupal apachesolr module folder into apache-solr/example/solr/conf/
Multisite / Multicore Setup
8) If you want multisite seach (multicore), here is what I did:
- duplicate the example folder to "sites"
- create a folder for each new website
- copy the conf folder from sites folder into each one of the website folders
- create a solr.xml file in the "sites" folder and defined a core for each of the sites.. here is what my sole.xml file looks like:
<solr persistent="false"> <!-- adminPath: RequestHandler path to manage cores. If 'null' (or absent), cores will not be manageable via request handler --> <cores adminPath="/admin/cores"> <core name="website1_core" instanceDir="website1.com" /> </cores> </solr>
9) Finally, in the Drupal ApacheSolr module, update the "Solr path" to the same core name you defined for the site in the sole.xml file. If you are using the example setup as outlined in the readme file that ships with the ApacheSolr Drupal module, you need not change anything as the default path the module ships with is correct. You only need to change this if you define your own cores.
Testing
If you are using the example site, test your installation as follows:
cd apache-solr/example sudo java -jar start.jar
If you are using the multicore setup from step 8, test as follows
cd apache-solr/sites sudo java -jar start.jar
Check the ApacheSolr admin page by visiting http://mydomain:8983/solr/admin/ or if you are using multicore http://mydomain:8983/solr/mycore_name/admin/
Auto start ApacheSolr on server reboot
You can follow the instructions on Want to start Apache solr automatically after a reboot? but depending on how you defined the cores above you will need to alter the path eg:
SOLR_DIR="/opt/apache-solr/example"
or
SOLR_DIR="/opt/apache-solr/sites"
Dont forget to change permissions on the sole bash file you created (etc/init.d/solr) and remember to install the script using chkconfig (all outlined in the guide above)
Security
By default, ApacheSolr does not ship with any kind of port protection, you are advised to secure your server ports by using iptables or a dedicated firewall (if you have one). For CentOS iptable guidelines click here

Nice! I've not had enough coffee this morning, to be sure, but did you skip the part where you start the server?
Also, in step 9, assuming you're using the packaged Jetty as per your instructions, the core to be used will be /solr, which is what the default values in the module are, so you won't need to modify anything.
Now, beware! There is no authentication at the Solr level, so you have to make sure that you don't open the 8983 (or 8080) port to the outside world. I use Uncomplicated Fire Wall http://ubuntuforums.org/showthread.php?t=823741 to close these ports to the outside world as a final step in my setup.

"Solr Gods" grace this humble website ;) I am no expert at this, so your input is much valued :)
Good points above Rob, yes I did skip that part from the tutorial as I assumed the user would be wanting to run the site using the proper Core setup I mentioned in step 8.
The script at the auto restart link adds a link to the example folder which the user can modify for their needs. But i have rewritten the tutorial to make it a little more clearer.
If the user defined a core as outlined in the setup above, then yes they should update the path to "solr/mycore_name" they defined in the solr.xml file. if not, it will use the defaults.
I included a link to the iptables setup on CentOS. I think the readme file that ships with the module should mention the security warning too!

Hi Janak,
Thanks for your great article. I followed along but somehow things went awry. When I run
sudo java -jar start.jarfrom within the example directory the app seems to hang. I get only this.
Error logs are blank aside from 404s which are returned whenever I try to hit http://mydomain:8983/solr/admin/.
I'm on a mediatemple dv 3.5 with centOS 5.2 (final)
Thanks,
Tim

Hi Tim,
It seems Jetty starts up fine for you! I had a similar issue where i could not connect to it using the admin interface! Have you checked the IPTables and SeLinux to make sure you have access to that port? I think by default (depending on setting) it will block the port! Be careful though as SeLinux can be a little tricky to configure.
Also make sure allow access to port 8983 from localhost only! Check my Further Reading section above for helpful links!

Hi Tim,
I'm sure you have already solved your problem. But for all of you who run into this headscratcher i found this:
Check if solr.war exists in your example/webapp folder. By default clean checkout of solr package comes without precompiled example "webapp"
To compile it yourself get ANT:
# apt-get install ant
or
# yum install ant
and in root of solr run:
# ant example
It will take a while to compile and when it's finished
# cd example
Now check if solor.war exists in webapps dir:
[root@xxxxxx example]# ls -l webapps/
total 4012
-rw-r--r-- 1 root root 4102706 Sep 2 15:35 solr.war
And try running solr again:
# sudo java -jar start.jar
Greetings,
Rafal

Hi Janak,
Thank you for the detailed instructions. Following them I installed everything and can't get it working.
I have Java 1.6.0_20 (probably this is the cause?)
Running sudo java -jar start.jar gives failed SocketConnector error:
What kind of advise you could give to me? Thanks again!

Hi yngens,
you need to install the ini.d script from http://drupal.org/node/545368. Once you have installed it, you can start apache solr by typing:
16th Oct, 10
Thanks again. I did install the script. Running and stopping it does not give any error:
root@host:/etc/init.d#
sudo /etc/init.d/solr stop
Stopping Solr
root@host:/etc/init.d#
sudo /etc/init.d/solr start
Starting Solr
However, it is still unavailable on http://mysite.com:8983/solr/admin/ and the status page still shows:
Your site was unable to contact the Apache Solr server.
If I run 'sudo java -jar start.jar' on /usr/local/share/apache-solr/example I get:
2010-10-16 02:58:11.300::WARN: failed SocketConnector @ 0.0.0.0:8983
java.net.BindException: Address already in use
I use APF and have opened port#8983, but did not touch any socket configurations since have no idea where I should configure them. I am worried about this error message, but can't figure out where I should look to solve it.

In step #8 for Multisite / Multicore Setup which "sites" folder we are talking about? The one, wich is in Drupal installation? For example, I have Drupal in '/usr/drupal/drupal6' and Apache Solr in '/usr/apache-solr'. Should I, in my case,
cp -R /usr/apache-solr/example /usr/drupal/drupal6/sites
and proceed with the rest of instructions?

I think I figured out I just need to copy 'example' folder in the same place as 'sites'. But then should I create a folder for each new website in 'sites' folder as 'sites/mysite1.com/', 'sites/mysite2.com/', 'sites/mysite3.com/', etc?
And copy '/usr/apache-solr/sites/solr/conf' (it is not in 'sites' folder, but 'sites'solr' forder) into each of newly created websites' folders?
Should I create a solr.xml file in the "sites" folder (not in of each websites folder?) and define a core for each of the sites in a single solr.xml file?
Sorry for being so pedantic, but I am that good in working in SSH, so would like to comply with your instructions as exact as possible. I've been fighting to make Apache Solr to work in my CENTOS 5.5 for already several days with no success. Still have that 'INFO: JNDI not configured for solr (NoInitialContextEx)
' error, but decided to try multisite setup first. Maybe it will work through?

Step 9 is not very clear, where is exactly sole.xml ?
