1、之前安裝了tomcat，所以現在把解壓完成後的apache-tomcat複製三份；

2、建立三個tomcat資料夾，分別把apache-tomcat-1，2，3 放入進去；

3、依次修改以下三個埠：

vim /usr/local/tomcat/apache-tomcat-1/conf/server.xml

Apache-tomcat-1；

//8011遠端停服務埠

<Server port="8011" shutdown="SHUTDOWN">

//8087為http埠 <Connector port="8087" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />

//8021為AJP埠，Apache能通過AJP協議訪問Tomcat的8006埠

<Connector port="8021" protocol="AJP/1.3" redirectPort="8443" />

Apache-tomcat-2；

//8012遠端停服務埠 

<Server port="8012" shutdown="SHUTDOWN">

//8088為http埠 <Connector port="8088" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />

//8022為AJP埠，Apache能通過AJP

<Connector port="8022" protocol="AJP/1.3" redirectPort="8443" />

Apache-tomcat-3；

//8013遠端停服務埠

<Server port="8013" shutdown="SHUTDOWN">

//8089為http埠 <Connector port="8089" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />

//8023為AJP埠，Apache能通過AJP協議訪問Tomcat的8006埠

<Connector port="8023" protocol="AJP/1.3" redirectPort="8443" />

分別加入防火牆：

firewall-cmd --add-port=8087/tcp --permanent

firewall-cmd --add-port=8087/udp --permanent

firewall-cmd --reload

為了驗證方便，修改tomcat首頁

/usr/local/tomcat/apache-tomcat-1/webapps/ROOT，開啟index.jsp檔案，把Home 分別改成Home8087,Home8088,Home8089

開啟瀏覽器，分別訪問：

192.168.52.129:8088；192.168.52.129:8086；192.168.52.129:8087

看看是否都可以訪問；
