Tomcat多实例

1.先把需要用到的压缩包导入

	cd /opt

2.配置jdk环境

	##解压jdk
	[root@localhost opt]#rpm -ivh jdk-8u201-linux-x64.rpm 
	##查看安装路径
	rpm -qpl jdk-8u201-linux-x64.rpm

3.添加环境变量

	##1可以做软连接到/usr/bin或者到/usr/sbin
	ln -s /usr/java/jdk1.8.0_201-amd64 /usr/bin/
	ln -s /usr/java/jdk1.8.0_201-amd64 /usr/sbin/

	##2可以移动到 /usr/bin或者/usr/sbin
	mv /usr/java/jdk1.8.0_201-amd64 /usr/bin/
	mv /usr/java/jdk1.8.0_201-amd64 /usr/sbin/

	##进入/etc/profile 添加环境变量
	添加到最后一行
	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
	#刷新一下文件
	source /etc/profile

4.解压tomcat包

	[root@localhost ~]# cd /opt/
	[root@localhost opt]# ls
	apache-tomcat-9.0.16.tar.gz  jdk-8u201-linux-x64.rpm  rh
	[root@localhost opt]# tar -zxf apache-tomcat-9.0.16.tar.gz

5.复制一份tomcat为tomcat1和tomcat2

	mkdir /usr/local/tomcat
	mv apache-tomcat-9.0.16 /usr/local/tomcat/tomcat1
	cd  /usr/local/tomcat
	cp -a tomcat1 tomcat2

5.修改tomcat2中的主配置文件 (修改端口就行)

	#只需要修改tomcat2中的主配置文件
	vim tomcat2/conf/server.xml
	22 
	69

6.修改启动脚本和关闭脚本

	#tomcat1
	vim /usr/local/tomcat/tomcat1/bin/startup.sh
	##添加在22行
	export CATALINA_HOME1=/usr/local/tomcat/tomcat1
	export CATALINA_base1=/usr/local/tomcat/tomcat1
	export TOMCAT_HOME1=/usr/local/tomcat/tomcat1

	vim /usr/local/tomcat/tomcat1/bin/shutdown.sh
	##添加在22行
	export CATALINA_HOME1=/usr/local/tomcat/tomcat1
	export CATALINA_base1=/usr/local/tomcat/tomcat1
	export TOMCAT_HOME1=/usr/local/tomcat/tomcat1


	#tomcat2
	添加在22行
	vim /usr/local/tomcat/tomcat1/bin/startup.sh
	export CATALINA_HOME2=/usr/local/tomcat/tomcat2
	export CATALINA_base2=/usr/local/tomcat/tomcat2
	export TOMCAT_HOME2=/usr/local/tomcat/tomcat2
	
	vim /usr/local/tomcat/tomcat1/bin/shutdown.sh
	##添加在22行
	export CATALINA_HOME2=/usr/local/tomcat/tomcat2
	export CATALINA_base2=/usr/local/tomcat/tomcat2
	export TOMCAT_HOME2=/usr/local/tomcat/tomcat2

7.启动tomcat1 tomcat2

	cd /usr/local/tomcat
	./tomcat1/bin/startup.sh
	./tomcat2/bin/startup.sh

8.查看端口有没有起

	ss -napt | grep java
	LISTEN     0      100         :::8080                    :::*                   users:				(("java",pid=47083,fd=54))
	LISTEN     0      100         :::8081                    :::*                   users:(("java",pid=47144,fd=54))
	LISTEN     0      1         ::ffff:127.0.0.1:8005                    :::*                   users:(("java",pid=47083,fd=74))
	LISTEN     0      1         ::ffff:127.0.0.1:8006                    :::*                   users:(("java",pid=47144,fd=74))
	LISTEN     0      100         :::8009                    :::*                   users:(("java",pid=47083,fd=59))
	LISTEN     0      100         :::8010                    :::*                   users:(("java",pid=47144,fd=59))

原本不可以多开，因为端口会冲突，这样就完成啦
