1. 基础环境准备

# 主机上完成JDK 和 tomcat 安装，完成基础环境的准备

install_tomcat

[root@Tomcat-HostsIP48 ]#bash install_tomcat2022.sh

2. 修改Tomcat的配置文件，实现基于主机头的虚拟主机

基本内容：修改Tomcat的配置文件，实现 w1.shone.cn 和 w2.shone.cn 基于主机头的两个虚拟主机。准备两个虚拟主机的网站目录及网页文件。

# 默认的 tomcat  /usr/local/tomcat/conf/server.xml  配置信息
[root@Tomcat-HostsIP48 ]#vim /usr/local/tomcat/conf/server.xml    
<?xml version="1.0" encoding="UTF-8"?>
<Server port="8005" shutdown="SHUTDOWN">

  <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" />
  <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />
  <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener" />

  <GlobalNamingResources>
    <Resource name="UserDatabase" auth="Container"
              type="org.apache.catalina.UserDatabase"
              description="User database that can be updated and saved"
              factory="org.apache.catalina.users.MemoryUserDatabaseFactory"
              pathname="conf/tomcat-users.xml" />
  </GlobalNamingResources>

  <Service name="Catalina">

    <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" 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="localhost"  appBase="webapps" unpackWARs="true" autoDeploy="true">

        <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs"
               prefix="localhost_access_log" suffix=".txt"
