Tomcat多实例部署及配置原理
作者：视觉装置在笑
这篇文章主要介绍了Tomcat多实例部署及配置过程，本文通过实例代码给大家介绍的非常详细，对大家的学习或工作具有一定的参考借鉴价值,需要的朋友可以参考下
1、关闭防火墙，将安装 Tomcat 所需软件包传到/opt目录下
jdk-8u201-linux-x64.rpm apache-tomcat-9.0.16.tar.gz systemctl stop firewalld systemctl disable firewalld setenforce 0
2、安装JDK
cd /opt rpm -qpl jdk-8u201-linux-x64.rpm rpm -ivh jdk-8u201-linux-x64.rpm java -version
3、安装 Tomcat
cd /opt tar zxvf apache-tomcat-9.0.16.tar.gz mkdir /usr/local/tomcat mv apache-tomcat-9.0.16 /usr/local/tomcat/tomcat1 cp -a /usr/local/tomcat/tomcat1 /usr/local/tomcat/tomcat2
4、配置 tomcat 环境变量
vim /etc/profile.d/tomcat.sh #tomcat1 export CATALINA_HOME1=/usr/local/tomcat/tomcat1 export CATALINA_BASE1=/usr/local/tomcat/tomcat1 export TOMCAT_HOME1=/usr/local/tomcat/tomcat1 #tomcat2 export CATALINA_HOME2=/usr/local/tomcat/tomcat2 export CATALINA_BASE2=/usr/local/tomcat/tomcat2 export TOMCAT_HOME2=/usr/local/tomcat/tomcat2 source /etc/profile.d/tomcat.sh
5、修改 tomcat2 中的 server.xml 文件，要求各 tomcat 实例配置不能有重复的端口号
vim /usr/local/tomcat/tomcat2/conf/server.xml <Server port="8006" shutdown="SHUTDOWN"> #22行，修改Server prot，默认为8005 -> 修改为8006 <Connector port="8081" protocol="HTTP/1.1" #69行，修改Connector port，HTTP/1.1 默认为8080 -> 修改为8081 <Connector port="8010" protocol="AJP/1.3" redirectPort="8443" /> #116行，修改Connector port AJP/1.3，默认为8009 -> 修改为8010
6、修改各 tomcat 实例中的 startup.sh 和 shutdown.sh 文件，添加 tomcat 环境变量
vim /usr/local/tomcat/tomcat1/bin/startup.sh # ----------------------------------------------------------------------------- # Start Script for the CATALINA Server # ----------------------------------------------------------------------------- ##添加以下内容 export CATALINA_BASE=$CATALINA_BASE1 export CATALINA_HOME=$CATALINA_HOME1 export TOMCAT_HOME=$TOMCAT_HOME1 vim /usr/local/tomcat/tomcat1/bin/shutdown.sh # ----------------------------------------------------------------------------- # Stop script for the CATALINA Server # ----------------------------------------------------------------------------- export CATALINA_BASE=$CATALINA_BASE1 export CATALINA_HOME=$CATALINA_HOME1 export TOMCAT_HOME=$TOMCAT_HOME1 vim /usr/local/tomcat/tomcat2/bin/startup.sh # ----------------------------------------------------------------------------- # Start Script for the CATALINA Server # ----------------------------------------------------------------------------- export CATALINA_BASE=$CATALINA_BASE2 export CATALINA_HOME=$CATALINA_HOME2 export TOMCAT_HOME=$TOMCAT_HOME2 vim /usr/local/tomcat/tomcat2/bin/shutdown.sh # ----------------------------------------------------------------------------- # Stop script for the CATALINA Server # ----------------------------------------------------------------------------- export CATALINA_BASE=$CATALINA_BASE2 export CATALINA_HOME=$CATALINA_HOME2 export TOMCAT_HOME=$TOMCAT_HOME2
7、启动各 tomcat 中的 /bin/startup.sh
/usr/local/tomcat/tomcat1/bin/startup.sh /usr/local/tomcat/tomcat2/bin/startup.sh netstat -natp | grep java
