tomcat配置

https://archive.apache.org/dist/tomcat/（往期的各个版本下载（选择版本进入bin目录下载）） 

 查看详细配置

1、<Host>标签的配置

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

　　<Context path="/" docBase="/website" debug="0" reloadable="true"/> <!-- 默认主页 -->

　　<Context path="/testapi" docBase="/war/testapi.war" debug="0" reloadable="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>

2、不更改配置文件自动解压war

　　将war文件放置到wepapps目录中就行了，tomcat会不定时的检查该目录的状态，默认几秒钟一次不是太清楚

 3、同一端口不同域名的配置（添加多个host标签）

　　1）大前提：必须在同一个Service标签中

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

　　<Context path="/" docBase="/war/testapi.war" debug="0" reloadable="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>
<Host name="api.hello.cn"  appBase="webapps"
      unpackWARs="true" autoDeploy="true">

    <Context path="/" docBase="/testapi" debug="0" reloadable="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>

4、不同端口的配置

　　1）大前提：必须有多个Service标签

　　2）多个Service标签的name值可以都一样，最好要不一样，方便检查

　　3) Service标签名和Engine可以随便写最好就是名字一致好看一些。
