Tomcat多实列部署

Centos7 yum安装jdk11
yum install -y java-11-openjdk*
​
查看yum中jdk版本：yum search jdk

1.安装好jdk并关闭防火墙

cd /opt
rpm -qpl jdk-8u201-linux-x64.rpm   ##查看指定文件的文件列表
rpm -ivh jdk-8u201-linux-x64.rpm   ##安装 jdk
java -version
​
systemctl stop firewalld
systemctl disable firewalld
setenforce 0

2.安装tomcat

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

3.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

4.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
​
第一个连接器默认监听8080端口，负责建立HTTP连接。在通过浏览器访问Tomcat服务器的Web应用时，使用的就是这个连接器。
第二个连接器默认监听8009端口，AJP端口，即容器使用，如Apache能通过AJP协议访问Tomcat的8009端口。

5.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 
##修改各tomcat实列中的startup.sh和shutdown.sh文件,添加tomcat环境变量
# -----------------------------------------------------------------------------
# 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

6.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

7.浏览器访问测试
