1、vim /etc/profile
##########first tomcat###########
CATALINA_BASE=/usr/apache-tomcat-8.0.-fore
CATALINA_HOME=/usr/apache-tomcat-8.0.-fore
TOMCAT_HOME=/usr/apache-tomcat-8.0.-fore
export CATALINA_BASE CATALINA_HOME TOMCAT_HOME
##########first tomcat############
##########second tomcat##########
CATALINA_2_BASE=/usr/apache-tomcat-8.0.-mgr
CATALINA_2_HOME=/usr/apache-tomcat-8.0.-mgr
TOMCAT_2_HOME=/usr/apache-tomcat-8.0.-mgr
export CATALINA_2_BASE CATALINA_2_HOME TOMCAT_2_HOME
##########second tomcat########## ##########third tomcat##########
CATALINA_3_BASE=/usr/apache-tomcat-8.0.-aoji
CATALINA_3_HOME=/usr/apache-tomcat-8.0.-aoji
TOMCAT_3_HOME=/usr/apache-tomcat-8.0.-aoji
export CATALINA_3_BASE CATALINA_3_HOME TOMCAT_3_HOME
##########third tomcat##########
2、刷新配置文件
source /etc/profile
3、修改tomcat/bin/catalina.sh
(1) 查找#OS specific support. $var _must_ be set to either true or false.
(2)在下面增加如下代码（对应123）
export CATALINA_BASE=$CATALINA_2_BASE
export CATALINA_HOME=$CATALINA_2_HOME
