It's been a while since I
first wrote about setting up
Solr on Ubuntu. Since then I've opted for a different approach that is both simpler and lighter-weight. This post describes briefly the steps to setting up Solr on Ubuntu.
Fetching the code
First step is to get a copy of Solr:
cd /tmp/
wget http://apache.mirrors.tds.net//lucene/solr/1.4.1/apache-solr-1.4.1.tgz
tar xzf apache-solr-1.4.1.tgz
Installing
I create a "solr" user and just put the webapp and all the configuration data in that user's home directory:
# create the solr user
sudo useradd solr
# copy the solr executable and sample conf to the solr home dir
sudo cp -R apache-solr-1.4.1/example/ /home/solr/
cd /home/solr/
If you want to use a multi-core configuration, you'll need to shuffle around the default conf:
sudo mv solr/ single-core
sudo mv multicore/ solr
Lastly, change permissions:
sudo chown -R solr:solr .
Testing it out
Now you're ready to test the installation. From the /home/solr/ directory, run the following:
sudo su solr
java -jar start.jar
You should see a bunch of output with this at the end:
2011-06-17 16:39:18.320::INFO: Started SocketConnector @ 0.0.0.0:8983
Solr's web interface is now available at:
http://your-server:8983/solr/
Using a process manager to start/stop Solr
I personally like supervisord for process management. Another popular option is
upstart. These tools can make it easy to automatically start Solr and are a good replacement for the more old-school "init" scripts.
Here's what my supervisor conf looks like:
[program:solr]
command=java -Xmx128m -jar start.jar
directory=/home/solr/
user=solr
autostart=true
autorestart=true
redirect_stderr=true
Hope this helps!
