Tomcat多实例部署

---

一、下载JDK包和tomcat包

二、安装JDK和tomcat

cd /opt
java -version
rpm -qpl jdk-8u371-linux-x64.rpm
rpm -ivh jdk-8u371-linux-x64.rpm 

tar zxvf apache-tomcat-8.5.16.tar.gz  #解压
mkdir /usr/local/tomcat
mv apache-tomcat-9.0.16 /usr/local/tomcat/tomcat1
cp -a /usr/local/tomcat/tomcat1 /usr/local/tomcat/tomcat2

三、配置 tomcat 环境变量

vim /etc/profile.d/java.sh
export JAVA_HOME=/usr/java/jdk1.8.0-x64
export CLASSPATH=.:$JAVA_HOME/lib/tools.jar:$JAVA_HOME/lib/dt.jar
export PATH=$JAVA_HOME/bin:$PATH


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

四、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

五、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

六、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

七、浏览器访问测试
