How to check the log when starting Tomcat on Linux.

To view the log of Tomcat, you can follow these steps:

1. Open the terminal window.
2. Navigate to the log directory of Tomcat using the cd command. Typically, the log directory of Tomcat is found in the “logs” folder within the installation directory of Tomcat. You can enter it by using the following command:

cd /path/to/tomcat/logs

Replace /path/to/tomcat with the actual installation path for your Tomcat.
3. Use the ls command to list log files and check the available ones. Common Tomcat log files include catalina.out, localhost.log, and catalina.log. You can use the following command to view the file list:

ls

1. The log file called catalina.out.

cat catalina.out

You can also use the tail command to view the latest few lines of the logs, for example:

tail -n 100 catalina.out

This will display the last 100 lines of the catalina.out file log.

By following these steps, you can view the log files of Tomcat and check for any errors and exceptions during the startup process.
