TOMCAT设置启动参数

tomcat/bin目录下的catalina.bat文件已经给了解决方案了，里面注释有如下内容：

#!/bin/sh

# Control Script for the CATALINA Server
#
# Environment Variable Prerequisites
#
#   Do not set the variables in this script. Instead put them into a script
#   setenv.sh in CATALINA_BASE/bin to keep your customizations separate.
#
#   CATALINA_HOME   May point at your Catalina "build" directory.

注意后面的那句话：

Do not set the variables in this script. Instead put them into a script

setenv.sh in CATALINA_BASE/bin to keep your customizations separate.

额外的变量可以设置在setenv.sh里面，如果没有这个文件，自己创建一个即可。比如：

#!/bin/sh

JAVA_OPTS="$JAVA_OPTS -Dxxx=abc"
