Tomcat多实例部署及配置原理

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 02、安装JDK

cd /opt

rpm -qpl jdk-8u201-linux-x64.rpm

rpm -ivh jdk-8u201-linux-x64.rpm

java -version3、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/tomcat24、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.sh5、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80106、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_HOME27、启动各 tomcat 中的 /bin/startup.sh

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

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