Once you get Solr working in Drupal you may find it handy to have your Solr instance start whenever your server is rebooted. Doing this is simple and done form the Command Line Interface (CLI). For the beginners (such as myself) you will need to have ssh access to your server. If you do not, ask your hosting company what your options are.
SSH into your server.
- Create a directory called cscripts: # mkdir cscripts
- Get into the directory: # cd /cscripts
- Create a new file called start.sh: # vi start.sh
- Press "i"
- On the first line enter these lines: cd /home/path/solr_folder_name/example (press enter) java -jar start.jar
- Press :w press enter and the :q and press enter
- Give the script world permission: # chmod og+x start.sh
- Now, test the script and ensure that it works correctly from the command line. # ./start.sh
- You shoudl now see the start.jar working. Press ctrl-c and break the process
Add the script to your rc.local file:
- # cd /etc
- Edit the rc.local file: # vi rc.local
- Press "i"
- At the end of the file put this command: cd /cscripts (press enter) ./start.sh
- Press :w press enter and the :q and press enter
Now reboot and test to make sure your process runs. You can do this by going into the module in Drupal and making sure your module can connect with the Solr server.
