1、关闭防火墙，将安装 Tomcat 所需软件包传到/opt目录下

1 jdk-8u201-linux-x64.rpm
2 apache-tomcat-9.0.16.tar.gz
3 
4 systemctl stop firewalld
5 systemctl disable firewalld
6 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

1 cd /opt
2 tar zxvf apache-tomcat-9.0.16.tar.gz
3 mkdir /usr/local/tomcat
4 mv apache-tomcat-9.0.16 /usr/local/tomcat/tomcat1
5 cp -a /usr/local/tomcat/tomcat1 /usr/local/tomcat/tomcat2

 

 

 

4、配置 tomcat 环境变量

 1 vim /etc/profile.d/tomcat.sh
 2 #tomcat1
 3 export CATALINA_HOME1=/usr/local/tomcat/tomcat1
 4 export CATALINA_BASE1=/usr/local/tomcat/tomcat1
 5 export TOMCAT_HOME1=/usr/local/tomcat/tomcat1
 6 
 7 #tomcat2
 8 export CATALINA_HOME2=/usr/local/tomcat/tomcat2
 9 export CATALINA_BASE2=/usr/local/tomcat/tomcat2
10 export TOMCAT_HOME2=/usr/local/tomcat/tomcat2
11 
12 
13 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

1 vim /usr/local/tomcat/tomcat2/conf/server.xml
2 <Server port="8006" shutdown="SHUTDOWN">        #22行，修改Server prot，默认为8005 -> 修改为8006
3 <Connector port="8081" protocol="HTTP/1.1"        #69行，修改Connector port，HTTP/1.1  默认为8080 -> 修改为8081
4 <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

 1 vim /usr/local/tomcat/tomcat1/bin/startup.sh 
 2 # -----------------------------------------------------------------------------
 3 # Start Script for the CATALINA Server
 4 # -----------------------------------------------------------------------------
 5 ##添加以下内容
 6 export CATALINA_BASE=$CATALINA_BASE1
 7 export CATALINA_HOME=$CATALINA_HOME1
 8 export TOMCAT_HOME=$TOMCAT_HOME1
 9 
10 
11 vim /usr/local/tomcat/tomcat1/bin/shutdown.sh
12 # -----------------------------------------------------------------------------
13 # Stop script for the CATALINA Server
14 # -----------------------------------------------------------------------------
15 export CATALINA_BASE=$CATALINA_BASE1
16 export CATALINA_HOME=$CATALINA_HOME1
17 export TOMCAT_HOME=$TOMCAT_HOME1
18 
19 
20 vim /usr/local/tomcat/tomcat2/bin/startup.sh 
21 # -----------------------------------------------------------------------------
22 # Start Script for the CATALINA Server
23 # -----------------------------------------------------------------------------
24 export CATALINA_BASE=$CATALINA_BASE2
25 export CATALINA_HOME=$CATALINA_HOME2
26 export TOMCAT_HOME=$TOMCAT_HOME2
27 
28 
29 vim /usr/local/tomcat/tomcat2/bin/shutdown.sh
30 # -----------------------------------------------------------------------------
31 # Stop script for the CATALINA Server
32 # -----------------------------------------------------------------------------
33 export CATALINA_BASE=$CATALINA_BASE2
34 export CATALINA_HOME=$CATALINA_HOME2
35 export TOMCAT_HOME=$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
