环境: 　　Tomcat8.0.53 目标: 　　设置为使用指定的域名或者IP访问

1. 设置IP访问

1.1 找到以下信息

<Host name="localhost"  appBase="webapps" unpackWARs="true" autoDeploy="true">

1.2 修改 name="localhost" 中的 "localhost" 为指定的IP,修改内容如下

<Host name="63.99.68.186"  appBase="webapps"
			unpackWARs="true" autoDeploy="true">
	<!-- SingleSignOn valve, share authentication between web applications
			 Documentation at: /docs/config/valve.html -->
	<!--
	<Valve className="org.apache.catalina.authenticator.SingleSignOn" />
	-->
	<!-- Access log processes all example.
			 Documentation at: /docs/config/valve.html
			 Note: The pattern used is equivalent to using pattern="common" -->
	<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
				 prefix="localhost_access_log" suffix=".txt"
				 pattern="%h %l %u %t "%r" %s %b" />
</Host>

2. 设置域名访问

2.1 找到以下信息

<Host name="localhost"  appBase="webapps" unpackWARs="true" autoDeploy="true">

2.2 修改 name="localhost" 中的 "localhost" 为指定的域名,这里需要指定一个别名,可以保证带www和不带www都能正常访问,修改内容如下:

<Host name="www.678910.top"  appBase="webapps"
			unpackWARs="true" autoDeploy="true">
	<Alias>678910.top</Alias>
	<!-- SingleSignOn valve, share authentication between web applications
			 Documentation at: /docs/config/valve.html -->
	<!--
	<Valve className="org.apache.catalina.authenticator.SingleSignOn" />
	-->
	<!-- Access log processes all example.
			 Documentation at: /docs/config/valve.html
			 Note: The pattern used is equivalent to using pattern="common" -->
	<Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
				 prefix="localhost_access_log" suffix=".txt"
				 pattern="%h %l %u %t "%r" %s %b" />

</Host>
