Tomcat多实例部署

一、安装好 jdk

cd /opt
rpm -qpl jdk-8u201-linux-x64.rpm 
rpm -ivh jdk-8u201-linux-x64.rpm 
java -version

1.1设置JDK环境变量

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=$JAVA_HOME/bin:$PATHsource /etc/profile.d/java.sh
java -versionsource /etc/profile

二、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

2.1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/tomcat2source /etc/profile.d/tomcat.sh

2.2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

2.3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=$TOMCAT_HOME1vim /usr/local/tomcat/tomcat1/bin/shutdown.sh# -----------------------------------------------------------------------------# Stop script for the CATALINA Server# -----------------------------------------------------------------------------export CATALINA_BASE=$CATALINA_BASE1
export CATALINA_HOME=$CATALINA_HOME1
export TOMCAT_HOME=$TOMCAT_HOME1vim /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=$TOMCAT_HOME2vim /usr/local/tomcat/tomcat2/bin/shutdown.sh# -----------------------------------------------------------------------------# Stop script for the CATALINA Server# -----------------------------------------------------------------------------export CATALINA_BASE=$CATALINA_BASE2
export CATALINA_HOME=$CATALINA_HOME2
export TOMCAT_HOME=$TOMCAT_HOME2

2.4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
