Configure the Catalina.out log format

When you start Tomcat, the log format that is output in catalina.out may not be ideal.

See the default format for some versions:

April 24, 2018 6:49:32 pm Org.apache.catalina.startup.Catalina start
Info: Server Startup in 9772 MS

A bit awkward, want to adjust to the following format:

24-apr-2018 18:52:16.134 INFO [main] Org.apache.catalina.startup.Catalina.start Server startup in 12631 MS

Google search "catalina.out log format", see some articles, found through the ${tomcat-base}/conf/logging.properties file configuration.

Where ${tomcat-base} refers to the working directory of the specific running instance. ${tomcat-home} is the installation directory.

That is, on a single server, you can install a Tomcat, specify multiple base working directories, and you can start multiple instances.

That's what the idea editor did. Through the jps-v can see some clues.

The specific configuration information is as follows, you can directly overwrite this file. or copy from the bottom of a valid instance.

Of course, upgrade is the best upgrade version.
