一、Tomcat多实例的操作步骤
1.1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
1.2安装JDK
jdk-8u201-linux-x64.rpm apache-tomcat-9.0.16.tar.gz vim /etc/profile.d/java.sh export JAVA_HOME=/usr/java/jdk1.8.0_201-amd64 export CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar export PATH=$JAVA_HOME/bin:$PATH source /etc/profile.d/java.sh java -version
1.3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
1.4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
1.5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
1.6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
1.7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
