Change port for Apache Solr from the default port 8983 on Ubuntu 16.04

This post introduces how to change the default port on which Apache Solr runs on Ubuntu 16.04.  (See my post if you have not installed Solr on your Ubuntu.)

The default port for Solr is 8983, but there are circumstances where you may want to change this. For example, if you wish to experiment with a new release, or you want your various Sitecore development instances to hit separate instances of Solr.  See below for two options for changing the port number on Ubuntu.

Step 1: use sudo service solr status to check your Solr status and the port it is running on.

yourusername@yourservername:~$ sudo service solr status
[sudo] password for yourusername: 
● solr.service - LSB: Controls Apache Solr as a Service

Apr 30 11:08:43 yourservername solr[2652]: [14B blob data]
Apr 30 11:08:43 yourservername systemd[1]: Started LSB: Controls Apache Solr as a Service.

Step 2: use sudo service solr stop to  stop your Solr first before we go ahead and change  its default port.

yourusername@yourservername:/opt/solr-6.5.1/bin$ sudo service solr stop
yourusername@yourservername:/opt/solr-6.5.1/bin$ sudo service solr status

Apr 30 11:08:43 yourservername solr[2652]: [14B blob data]

May 07 15:40:57 yourservername systemd[1]: Stopped LSB: Controls Apache Solr as a Service.

Step 3: Change config files

Check out all the following files for the port:

  • cd to /opt/solr-6.5.1/server/solr/
#the file path: /opt/solr-6.5.1/server/solr/solr.xml
yourusernmae:/opt/solr-6.5.1/server/solr$ sudo nano solr.xml
#change port here:  ${jetty.port:8983}
  • cd to /var/
# the file path: /var/solr/data/solr.xml
yourusernmae:/var$ sudo nano /solr/data/solr.xml
# change port here:  ${jetty.port:8983}
  • cd to /etc/default/
# the file path: /etc/default/solr.in.sh
yourusernmae:/etc/default$ sudo nano solr.in.sh
# change port here:  SOLR_PORT=8983

Once you save and close the solr.in.sh file you can return to your terminal and type this command to reload the file 

yourusernmae:/etc/default$ source solr.in.sh

Step 4: Start your solr service again using  sudo service solr start, you will see your solr is now running on the new port your changed just now in the step 3 above.

yourusername@yourservername:/etc/default$ sudo service solr start
yourusername@yourservername:/etc/default$ sudo service solr status
● solr.service - LSB: Controls Apache Solr as a Service

 Process: 17121 ExecStart=/etc/init.d/solr start (code=exited, status=0/SUCCESS)

May 07 16:11:29 yourservername systemd[1]: Starting LSB: Controls Apache Solr as a Service...
May 07 16:11:29 yourservername su[17125]: Successful su for solr by root

Now you can reference Step 5: Creating a Solr search collection in my another post to create a Solr search collection for this port.
