linux下启动多个tomcat

1.改变不同tomcat的启动与关闭端口，每个tomcat 都用不同的端口，修改下面的两个配置 tomcat/conf/server.xml

  

<Server port="8005" shutdown="SHUTDOWN">

<Connector executor="tomcatThreadPool"

port="8080" protocol="HTTP/1.1"

connectionTimeout="20000"

redirectPort="8443" />

  

2.配置不同的CATALINA环境变量，不同的tomcat要各自指定自己的CATALINA环境变量

/etc/profile中加入

#tomcat 8080

CATALINA_8080_BASE=/usr/local/tomcat/tomcat9.8080

CATALINA_8080_HOME=/usr/local/tomcat/tomcat9.8080

TOMCAT_8080_BASE=/usr/local/tomcat/tomcat9.8080

export CATALINA_8080_BASE CATALINA_8080_HOME TOMCAT_8080_BASE

  

#tomcat 8081

CATALINA_8081_BASE=/usr/local/tomcat/tomcat9.8081

CATALINA_8081_HOME=/usr/local/tomcat/tomcat9.8081

TOMCAT_8081_BASE=/usr/local/tomcat/tomcat9.8081

export CATALINA_8081_BASE CATALINA_8081_HOME TOMCAT_8081_BASE

  

  

修改tomcat/bin/catalina.sh ,加入环境变量，不同的tomcat引入不同的环境变量

export CATALINA_BASE=$CATALINA_8080_BASE

export CATALINA_HOME=$CATALINA_8080_HOME

  

然后就可以启动多个tomcat了
