Tomcat之虚拟主机

1.创建存放网页的目录

mkdir -p /web/{a,b}

2.添加jsp文件
vi /web/a/index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<html>
<head><title>JSP a page</title>
</head>
<body><% out.println("Welcome to the test site, http://www.a.com"); %>
</body>
</html>

vi /web/b/index.jsp

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<html>
<head><title>JSP b page</title>
</head>
<body><% out.println("Welcome to the test site, http://www.b.com"); %>
</body>
</html>

3.添加主机信息
cd /opt/apache-tomcat-8.5.90/conf/

vi server.xml

1)定位到 </Engine>上面:

添加如下信息:

<Host name="www.a.com" appBase="webapps" unpackWARs="true" autoDeploy="true"><Context docBase="/web/a" path="" reloadable="false" /><Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"prefix="localhost_access_log" suffix=".txt"pattern="%h %l %u %t &quot;%r&quot; %s %b" />
</Host><Host name="www.b.com" appBase="webapps" unpackWARs="true" autoDeploy="true"><Context docBase="/web/b" path="" reloadable="false" /><Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"prefix="localhost_access_log" suffix=".txt"pattern="%h %l %u %t &quot;%r&quot; %s %b" />
</Host>

2)将之前的host注释掉

<!--      <Host name="localhost"  appBase="webapps"unpackWARs="true" autoDeploy="true"> --><!-- SingleSignOn valve, share authentication between web applicationsDocumentation at: /docs/config/valve.html --><!--<Valve className="org.apache.catalina.authenticator.SingleSignOn" />--><!-- Access log processes all example.Documentation at: /docs/config/valve.htmlNote: 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 &quot;%r&quot; %s %b" />  --><!--      </Host> -->

systemctl restart tomcat

4.域名映射

vim /etc/hosts

192.168.233.132 www.a.com www.b.com

5.在linux中的firefox中访问

www.a.com:8080
