03.Tomcat配置

接下来我们来讲讲简单的配置Tomcat。 　　‍

Tomcat后台管理

默认情况下，我们安装Tomcat之后，访问Tomcat主页面，出现如下图所示界面：

​​​​

‍

当我们需要访问Manager App或者Host Manager时：

‍

‍

提示需要密码：

‍

不输入会提示出现如下所示的错误：401

‍

增加用户

401表示无权限。根据提示，我们需要在Tomcat安装目录下的conf/tomcat-users.xml配置文件中增加用户角色和用户。

另外，还需要修改webapps/manager/META-INF/context.xml配置文件，修改访问地址的限制。

一、增加用户角色和用户：conf/tomcat-users.xml，我们在<tomcat-users>​标签体里增加如下角色和一个admin用户：

<role rolename="admin-gui"/>
<role rolename="manager-gui"/>
<role rolename="manager-jmx"/>
<role rolename="manager-script"/>
<role rolename="manager-status"/>
<user username="admin" password="123456" roles="admin-gui,manager-gui,manager-jmx,
manager-script,manager-status"/>

‍

‍

二、修改地址访问限制：webapps/manager/META-INF/context.xml

更改之前的设置，只容许本机访问：第22行里配置了只允许本机访问127.0.0.1

<Context antiResourceLocking="false" privileged="true" >
  <CookieProcessor className="org.apache.tomcat.util.http.Rfc6265CookieProcessor"
                   sameSiteCookies="strict" />
  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
  <Manager sessionAttributeValueClassNameFilter="java\.lang\.(?:Boolean|Integer|Long|Number|String)|org\.apache\.catalina\.filters\.CsrfPreventionFilter\$LruCache(?:\$1)?|java\.util\.(?:Linked)?HashMap"/>
</Context>

‍

更改为：

<Context antiResourceLocking="false" privileged="true" >
  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="^.*$" />
</Context>

‍

更改配置之后，重启Tomcat，访问Manager App和Host Manager就没有问题了

Manager App：

​​

‍

Host Manager：

‍

‍

server.xml其他配置

server.xml 文件当中可配置如下信息：

配置端口号：大概69行处

<Connector executor="tomcatThreadPool"
port="8080" protocol="HTTP/1.1"
connectionTimeout="20000"
redirectPort="8443" />

‍

‍

配置域名：修改 localhost标签里的name属性（151行处左右）

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