服务器上部署多个tomcat并启用不同端口

步骤依次为：

1.创建文件夹并拷贝原始tomcat文件夹中内容

cd /usr/local

mkdir tomcat8_8081

cp tomcat8_8080/* tomcat8_8081

2.修改tomcat8_8081/conf/server.xml中的端口号

vim tomcat8_8081/conf/server.xml

<Server port="8006" shutdown="SHUTDOWN">

<Connector port="8081" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
    <!-- A "Connector" using the shared thread pool-->
    <!--
    <Connector executor="tomcatThreadPool"
               port="8081" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />

<!-- Define an AJP 1.3 Connector on port 8009 -->
    <Connector port="8010" protocol="AJP/1.3" redirectPort="8443" />
    -->

3.修改环境变量

vim /etc/profile

在文件末尾加上

CATALINA_BASE_8080=/usr/local/tomcat8_8080
CATALINA_HOME_8080=/usr/local/tomcat8_8080
TOMCAT_HOME__8080=/usr/local/tomcat8_8080
export CATALINA_BASE_8080 CATALINA_HOME_8080 TOMCAT_HOME_8080

CATALINA_BASE_8081=/usr/local/tomcat8_8081
CATALINA_HOME_8081=/usr/local/tomcat8_8081
TOMCAT_HOME__8081=/usr/local/tomcat8_8081
export CATALINA_BASE_8081 CATALINA_HOME_8081 TOMCAT_HOME_8081
