一、Tomcat多实例的操作步骤
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
8、浏览器访问测试

二、实例操作:Tomcat多实例
1、关闭防火墙,将安装 Tomcat 所需软件包传到/opt目录下
[root@192 ~]# cd /opt/ [root@192 opt]# rz -E rz waiting to receive. [root@192 opt]# rz -E rz waiting to receive. [root@192 opt]# ls apache-tomcat-9.0.16.tar.gz jdk-8u201-linux-x64.rpm rh [root@192 opt]# systemctl stop firewalld [root@192 opt]# systemctl disable firewalld [root@192 opt]# setenforce 0 setenforce: SELinux is disabled
2、安装JDK
2.1 安装JDK并加入环境变量
[root@192 opt]# ls apache-tomcat-9.0.16.tar.gz jdk-8u201-linux-x64.rpm rh [root@192 opt]# rpm -ivh jdk-8u201-linux-x64.rpm 警告:jdk-8u201-linux-x64.rpm: 头V3 RSA/SHA256 Signature, 密钥 ID ec551f03: NOKEY 准备中... ################################# [100%] 正在升级/安装... 1:jdk1.8-2000:1.8.0_201-fcs ################################# [100%] Unpacking JAR files... tools.jar... plugin.jar... javaws.jar... deploy.jar... rt.jar... jsse.jar... charsets.jar... localedata.jar... [root@192 opt]# 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
2.2 运行脚本文件,然后查看jdk版本
[root@192 opt]# vim /etc/profile.d/java.sh [root@192 opt]# java -version openjdk version "1.8.0_131" OpenJDK Runtime Environment (build 1.8.0_131-b12) OpenJDK 64-Bit Server VM (build 25.131-b12, mixed mode) [root@192 opt]# source /etc/profile.d/java.sh [root@192 opt]# java -version java version "1.8.0_201" Java(TM) SE Runtime Environment (build 1.8.0_201-b09) Java HotSpot(TM) 64-Bit Server VM (build 25.201-b09, mixed mode)
3、安装 tomcat
[root@192 opt]# ls apache-tomcat-9.0.16.tar.gz jdk-8u201-linux-x64.rpm rh [root@192 opt]# tar zxvf apache-tomcat-9.0.16.tar.gz [root@192 opt]# ls apache-tomcat-9.0.16 apache-tomcat-9.0.16.tar.gz jdk-8u201-linux-x64.rpm rh [root@192 opt]# mkdir /usr/local/tomcat [root@192 opt]# mv apache-tomcat-9.0.16 !$ mv apache-tomcat-9.0.16 /usr/local/tomcat [root@192 opt]# cd /usr/local/tomcat/ [root@192 tomcat]# ls apache-tomcat-9.0.16 [root@192 tomcat]# mv apache-tomcat-9.0.16/ tomcat1 [root@192 tomcat]# cp -a tomcat1/ tomcat2 [root@192 tomcat]# ls tomcat1 tomcat2
4、配置 tomcat 环境变量
[root@192 tomcat]# 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
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
6、修改各 tomcat 实例中的 startup.sh 和 shutdown.sh 文件,添加 tomcat 环境变量
6.1 修改tomcat1的startup.sh
6.2 修改tomcat1的shutdown.sh
6.3 修改tomcat2的startup.sh
6.4 修改tomcat2的shutdown.sh
7、启动各 tomcat 中的 /bin/startup.sh
[root@192 ~]# /usr/local/tomcat/tomcat1/bin/startup.sh Using CATALINA_BASE: /usr/local/tomcat/tomcat1 Using CATALINA_HOME: /usr/local/tomcat/tomcat1 Using CATALINA_TMPDIR: /usr/local/tomcat/tomcat1/temp Using JRE_HOME: /usr/java/jdk1.8.0_201-amd64 Using CLASSPATH: /usr/local/tomcat/tomcat1/bin/bootstrap.jar:/usr/local/tomcat/tomcat1/bin/tomcat-juli.jar Tomcat started. [root@192 ~]# /usr/local/tomcat/tomcat2/bin/startup.sh Using CATALINA_BASE: /usr/local/tomcat/tomcat2 Using CATALINA_HOME: /usr/local/tomcat/tomcat2 Using CATALINA_TMPDIR: /usr/local/tomcat/tomcat2/temp Using JRE_HOME: /usr/java/jdk1.8.0_201-amd64 Using CLASSPATH: /usr/local/tomcat/tomcat2/bin/bootstrap.jar:/usr/local/tomcat/tomcat2/bin/tomcat-juli.jar Tomcat started. [root@192 ~]# netstat -natp | grep java tcp6 0 0 :::8080 :::* LISTEN 3552/java tcp6 0 0 :::8081 :::* LISTEN 3609/java tcp6 0 0 127.0.0.1:8005 :::* LISTEN 3552/java tcp6 0 0 127.0.0.1:8006 :::* LISTEN 3609/java tcp6 0 0 :::8009 :::* LISTEN 3552/java tcp6 0 0 :::8010 :::* LISTEN 3609/java
