# Changing Port for Tomcat

In the event that the port for tomcat (8081) needs to be changed the following will need to be done:

1. Change tomcat’s *server.xml* file to reflect the new port number:
  1. vi /var/lib/brains/app/apache-tomcat8/conf/server.xml
  2. Edit line 33 that reads as below and only change 8081 to the new port and then save your changes:
  3. <Connector port="*8081*" protocol="HTTP/1.1" SSLEnabled="true"
2. Restart the platform service:
  1. *systemctl restart brainspace-platform*
3. Update brainspace-haproxy config file to the new port:
  1. *vi /etc/brainspace/haproxy/brainspace-haproxy.cfg*
  2. Edit line 106 that reads as below and only change 8081 to the new port and then save your changes:
    1. *server localhost_ssl 127.0.0.1:****8081*** ssl verify none check
4. Restart brainspace-haproxy:
  1. *systemctl restart brainspace-haproxy*
5. Login to the UI, and
  1. Navigate to the Services Tab.
  2. Update the port (*8081*) for the Application Server,
  3. Click **Save**.

> [!NOTE]
> **Note**
> 
> Making changes to the default port is not recommended. If this is changed it will need to be checked and possibly changed again after an upgrade is performed.
