1. If the Tomcat file name does not have a soft connection, modify it.

Name = Tomcat

2. If the user name and group name are not tomcat, modify them.

# Run Tomcat as this user ID and group ID

Tomcat_user = Tomcat

Tomcat_group = Tomcat

3. If java_home is not present this time, add it or set java_home in your environment variables.
