本文详细介绍了如何克隆一个Tomcat服务，包括在配置文件`server.xml`和`startup.sh`中修改端口，以及如何在新服务中设置默认欢迎页面。克隆过程中涉及的主要步骤包括更新服务启动相关的配置，如端口号和目录路径，并确保新克隆的服务能够正常启动并监听正确的端口。

一.与tomcat服务启动相关的配置文件及主要参数(本例tomcat安装在server下)

1.1 /server/tomcat/conf/server.xml (标红的端口和目录，在克隆tomcat服务时需要更改)

<?xml version='1.0' encoding='utf-8'?>
<Server port="8005" shutdown="SHUTDOWN">
......
<Connector port="8080" protocol="org.apache.coyote.http11.Http11NioProtocol"
......
<Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

......

<Host name="localhost" appBase="/server/tomcat/webapps/"

1.2. /server/tomcat/bin/startup.sh (标红的端口，在克隆tomcat服务时需要更改)

......

declare -x CATALINA_OPTS="-server -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8788"

......

2.1 默认欢迎页面的配置 /server/tomcat/conf/web.xml （本例使用的默认访问页面为index.jsp）

<welcome-file-list>
<welcome-file>index.html</welcome-file>
<welcome-file>index.htm</welcome-file>
<welcome-file>index.jsp</welcome-file>
</welcome-file-list>

2.2默认欢迎页面的存放路径 /server/tomcat/webapps/ROOT/index.jsp (本例的程序包放置在了ROOT下)

二.依照如上已有tomcat服务，在同一台服务器上克隆一份新的tomcat服务

1.1 /server/tomcat_test/conf/server.xml (标红的端口和目录，在克隆tomcat服务时需要更改)

<?xml version='1.0' encoding='utf-8'?>
<Server port="8006" shutdown="SHUTDOWN">
......
<Connector port="8081" protocol="org.apache.coyote.http11.Http11NioProtocol"
......
<Connector port="8010" protocol="AJP/1.3" redirectPort="8443" />

......

注：若需更改web项目的访问路径，可在Context path标签内进行设置

1.2. /server/tomcat_test/bin/startup.sh (标红的端口，在克隆tomcat服务时需要更改)

......

declare -x CATALINA_OPTS="-server -Xdebug -Xnoagent -Djava.compiler=NONE -Xrunjdwp:transport=dt_socket,server=y,suspend=n,address=8888"

......

2.默认欢迎页面的存放路径 /server/tomcat_test/webapps/ROOT/index.jsp (本例的程序包放置在了ROOT下)

3启动新克隆的tomcat服务

3.1tomcat日志验证服务启动状态

[root@v-api-scdata-calc01 logs]# tail -f catalina.out
2018-01-08 17:36:34,152 [main] INFO org.apache.coyote.http11.Http11NioProtocol- Initializing ProtocolHandler ["http-nio-8081"]

2018-01-08 17:36:34,686 [main] INFO org.apache.coyote.ajp.AjpProtocol- Starting ProtocolHandler ["ajp-bio-8010"]
2018-01-08 17:36:34,695 [main] INFO org.apache.catalina.startup.Catalina- Server startup in 518 ms

3.2centos后台验证tomcat服务端口是否已启用

[root@v-api-scdata-calc01 bin]# netstat -tunlp (本例可见，克隆的tomcat服务相应端口都已启动)
