TOMCAT多实例部署

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

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

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

192.168.160.40:8080
192.168.160.40:8081

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

2、运行脚本文件，然后查看jdk版本

3、安装 tomcat

4、配置 tomcat 环境变量

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

8、浏览器访问测试
