Centos7上部署三台tomcat

• 复制三个tomcat压缩包分别解压到三个文件夹下

• 配置profile

vim /etc/profile

• 加入如下代码

##########8081 tomcat###########
CATALINA_BASE=/usr/java/apache-tomcat-9.0.13
CATALINA_HOME=/usr/java/apache-tomcat-9.0.13
TOMCAT_HOME=/usr/java/apache-tomcat-9.0.13
export CATALINA_BASE CATALINA_HOME TOMCAT_HOME
##########first tomcat############
##########8082 tomcat##########
CATALINA_2_BASE=/usr/java/apache-tomcat-9.0.13_2
CATALINA_2_HOME=/usr/java/apache-tomcat-9.0.13_2
TOMCAT_2_HOME=/usr/java/apache-tomcat-9.0.13_2
export CATALINA_2_BASE CATALINA_2_HOME TOMCAT_2_HOME
##########second tomcat#########
##########8083 tomcat##########
CATALINA_3_BASE=/usr/java/apache-tomcat-9.0.13_3
CATALINA_3_HOME=/usr/java/apache-tomcat-9.0.13_3
TOMCAT_3_HOME=/usr/java/apache-tomcat-9.0.13_3
export CATALINA_3_BASE CATALINA_3_HOME TOMCAT_3_HOME
##########third tomcat##########
##########8080 tomcat##########
CATALINA_0_BASE=/usr/java/apache-tomcat-9.0.0.M26
CATALINA_0_HOME=/usr/java/apache-tomcat-9.0.0.M26
TOMCAT_0_HOME=/usr/java/apache-tomcat-9.0.0.M26
export CATALINA_0_BASE CATALINA_0_HOME TOMCAT_0_HOME
##########8080 tomcat##########

• 保存退出、使生效（必须）

:wq
# 生效
source /etc/profile

• 配置catalina.sh (apache-tomcat-9.0.13_2)

vim usr/java/apache-tomcat-9.0.13_2/bin/catalina.sh 
vim usr/java/apache-tomcat-9.0.13_3/bin/catalina.sh 

• 在代码# OS specific support. $var _must_ be set to either true or false.下面增加如下代码

export CATALINA_BASE=$CATALINA_2_BASE
export CATALINA_HOME=$CATALINA_2_HOME

• 配置catalina.sh (apache-tomcat-9.0.13_3)

vim usr/java/apache-tomcat-9.0.13_3/bin/catalina.sh 

• 在代码# OS specific support. $var _must_ be set to either true or false.下面增加如下代码

export CATALINA_BASE=$CATALINA_3_BASE
export CATALINA_HOME=$CATALINA_3_HOME

只配置(apache-tomcat-9.0.13_2)和(apache-tomcat-9.0.13_3)相关，(apache-tomcat-9.0.13)保持不变

• 进入tomcat配置文件server.xml

cd /usr/java/apache-tomcat-9.0.13_3/conf

• 编辑server.xml

vim server.xml

• 修改三个地方即可

<Server port="8008" shutdown="SHUTDOWN">
<Connector port="8083" protocol="HTTP/1.1"
<Connector port="8011" protocol="AJP/1.3" redirectPort="8443" />           

apache-tomcat-9.0.13_2同理配置即可

• 分别进入tomcat的bin目录后台启动

./startup.sh | tail -f ../logs/catalina.out &

记得tail查看日志（养成良好的习惯），控制台正常无报错。

apache-tomcat-9.0.13：8081端口号

apache-tomcat-9.0.13_2：8082端口号

apache-tomcat-9.0.13_3：8083端口号
