CATALINA_OPTS

　　按照catalina.sh文档中的注释，CATALINA_OPTS（可选）是在执行“开始”，“运行”或“调试”命令时使用的Java运行时选项。在此处包含所有选项，而不是在JAVA_OPTS中包含所有选项，这些选项只能由Tomcat本身使用，而不能由停止进程，版本命令等使用。示例包括堆大小，GC日志记录，JMX端口等。

CATALINA_OPTS (Optional) Java runtime options used when the "start", "run" or "debug" command is executed. Include here and not in JAVA_OPTS all options, that should only be used by Tomcat itself, not by the stop process, the version command etc. Examples are heap size, GC logging, JMX ports etc.

JAVA_OPTS (Optional) Java runtime options used when any command is executed. Include here and not in CATALINA_OPTS all options, that should be used by Tomcat and also by the stop process, the version command etc. Most options should go into CATALINA_OPTS.
