Tomcat虚拟主机

虚拟主机用在一台物理机上搭建多个web站点，且互不影响

基于域名的主机

• 根据来访问的域名解析对应每个不同的web站点
• 配置域名与ip的映射管理（hosts）
  在host文件中添加对应的ip域名17,19

  vim /etc/hosts
  192.168.200.19  www.linuxxu.com
  192.168.200.18  www.cloud.com
  

• 修改server.xml创建host模块对应域名

  vim /usr/local/tomcat8/conf/server.xml 
  <Host name="www.linuxxu.com"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
                <Context docBase="/web/linuxxu" path="" reloadable="flase">            
                </Context>
  
        <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.whml.com"  appBase="webapps"
            unpackWARs="true" autoDeploy="true">
                <Context docBase="/web/whml" path="" reloadable="flase">  
                </Context>
  
        <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>
  
  

• 创建域名对应路径

  mkdir -pv /web/{linuxxu,cloud}
  #对应创建index.jsp文件
  <%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
  

<% out.println("Welcome to test site,http://www.对应域名.com");%> ```

• 测试页面

基于端口的主机

• 修改server.xml配置文件

  <Service name="Catalina">
    <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" />
    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
    <Engine name="Catalina" defaultHost="localhost">
      <Realm className="org.apache.catalina.realm.LockOutRealm">
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/>
      </Realm>
        <Host name="www.jalja1.org"  appBase="E:/学习/activeMq/app1" unpackWARs="true" autoDeploy="true">
            <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
            prefix="localhost_access_log." suffix=".txt"
            pattern="%h %l %u %t "%r" %s %b" />
        </Host>
    </Engine>
  </Service>
  
  <Service name="Catalina2">
    <Connector port="8888" protocol="HTTP/1.1"  connectionTimeout="20000" redirectPort="8443" />
    <Connector port="8010" protocol="AJP/1.3" redirectPort="8443" />
    <Engine name="Catalina2" defaultHost="localhost">
      <Realm className="org.apache.catalina.realm.LockOutRealm">
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/>
      </Realm>
        <Host name="www.jalja1.org"  appBase="E:/学习/activeMq/app2" unpackWARs="true" autoDeploy="true">
            <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
            prefix="localhost_access_log." suffix=".txt"
            pattern="%h %l %u %t "%r" %s %b" />
        </Host>
    </Engine>
  </Service>
  

基于ip的主机

• 配置多个子网接口，一一对应rever.xml里的web站点

Tomcat多实例配置
