Tomcat多实例部署及配置原理

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
