关于CATALINA_BASE

对CATALINA_BASE目录的官方推荐：

• The bin directory with the setenv.sh, setenv.bat, and tomcat-juli.jar files.

  Recommended: No.

  Order of lookup: CATALINA_BASE is checked first; fallback is provided to CATALINA_HOME.

• The lib directory with further resources to be added on classpath.

  Recommended: Yes, if your application depends on external libraries.

  Order of lookup: CATALINA_BASE is checked first; CATALINA_HOME is loaded second.

• The logs directory for instance-specific log files.

  Recommended: Yes.

• The webapps directory for automatically loaded web applications.

  Recommended: Yes, if you want to deploy applications.

  Order of lookup: CATALINA_BASE only.

• The work directory that contains temporary working directories for the deployed web applications.

  Recommended: Yes.

• The temp directory used by the JVM for temporary files.

  Recommended: Yes.

不建议修改 tomcat-juli.jar file。 然而，如果您需要自己的日志记录实现，你可以在特定tomcat的实例的CATALINA_BASE中替换tomcat-juli.jar。

我们也建议你复制CATALINA_HOME/conf所有的文件到CATALINA_BASE/conf的目录中。万一CATALINA_BASE缺失某个配置文件，该tomcat实例并不会去CATALINA_HOME中复查。因此，可能会启动失败。

最起码，CATALINA_BASE必须包含：

• conf/server.xml
• conf/web.xml

这包括conf目录。否则，Tomcat将无法启动，或者无法正常运行。
