假设www.ctool.top。ip：192.168.122.135

step 1

申请一个域名并做好DNS解析，或者在hosts文件做域名指向

#vim /etc/hosts

www.ctool.top  192.168.122.135

step2

将index.html设置项目的默认首页，修改项目的web.xml文件

#vim web.xml

<welcome-file-list>

<welcome-file>index.html</welcome-file>

</welcome-file-list>

step3

改tomcat的访问端口为8083

<Connector port="8083" protocol="HTTP/1.1"

connectionTimeout="20000"

step4

将Engine标签下的defaults更改为您设置的域名

<Engine name="Catalina" defaultHost="www.ctool.top">

step5

<Host name="www.ctool.top"  appBase="webapps"

unpackWARs="true" autoDeploy="true">

step6

在</Host>标签前添加<Context docBase="ctool" path="" reloadable="true"/> 其中docBase为需要访问的项目名称

结束！！！！！！！
