tomcat server.xml 端口 略解

从做开发到现在虽然一直在用tomcat，但是没有真正的了解过他（感觉有点羞愧）
今后逐步的会揭开tomcat这层薄雾。
今天我们首先来看一下server.xml配置文件各个端口的作用

<Server port="8005" shutdown="SHUTDOWN">  <Listener className="org.apache.catalina.startup.VersionLoggerListener" />    <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" />    <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="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true">        <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>    </Engine>  </Service></Server>

<Server port="8005" shutdown="SHUTDOWN">8005端口指的是tomcat容器的运行端口也是tomcat在执行启动和关闭操作时操作的端口号

8080端口指的是http协议访问的端口号，即http://localhost:8080/

8443是https使用的端口号，现在默认都使用443

8009是AJP端口是apache服务器在做代理转发时用到的AJP服务，现在大多数的用的服务器都是nginx，这个端口一般用不到，除非公司有特定的需求

以上属个人理解， 如有错误指出，请不吝赐教!
