How to check the status of Tomcat processes in Linux?

To check the status of the Tomcat process, you can use the following command:

1. Check the running Tomcat processes using the command ‘ps’.

ps -ef | grep tomcat

This command will return all processes containing the keyword “tomcat,” including the main process of Tomcat and other related processes.

1. Use the jps command to view Java processes and find the PID of the main Tomcat process.

jps -l

This command will display all running Java processes in the system along with their PIDs, and you can identify the main Tomcat process by its identifier.

1. Check the ports that Tomcat is listening on using the netstat command.

netstat -tlnp | grep java

This command will display all listening network connections and their corresponding processes, allowing you to identify the Tomcat process by examining the port number.

1. Check the status of Tomcat using the Tomcat management interface or commands.

http://localhost:8080/manager/html

Opening this URL in a browser will display the management interface of Tomcat if it is running properly, where you can check the status and memory usage of various applications.

If none of the above methods are able to properly check the status of the Tomcat process, it could be due to Tomcat not being started or having a configuration issue.
