Hi there,

This very common requirement when we need to install Liferay patch to our server, usually Lifeary team is provide steps along with patch but in case if you don't have it you can follow below mentioned steps.

Following are the steps for install patch in Liferay, Please go through it step by steps.

Here PATCHING_TOOL_HOME = Path to the “patching-tool” directory in your tomcat.

How to do it ?

• Stop Tomcat.
• Place the patch(.zip file) in the PATCHING_TOOL_HOME/patches/ directory.
• Open command prompt.
• Go to PATCHING_TOOL_HOME directory.
• Give command “patching-tool auto-discovery” for Windows and “./patching-tool.sh auto-discovery” for Linux.
• Check that default.properties file will be created in PATCHING_TOOL_HOME
  directory.
