02 通过Web管理Tomcat

1. 简介

    测试功能，生产环境不要用。

    Tomcat管理功能用于对Tomcat自身以及部署在Tomcat上的应用进行管理的web应用。在默认情况下是处于禁用状态的。如果需要开启这个功能，就需要配置管理用户，即配置前面说过的tomcat-users.xml。

1.1.1 修改配置

[root@centos7 bin]# sed -i.bak '$i <role rolename="manager-gui"/>\n<role rolename="admin-gui"/>\n<user username="tomcat" password="tomcat" roles="manager-gui,admin-gui"/>' /usr/local/tomcat/conf/tomcat-users.xml
[root@centos7 bin]# tail -4 /usr/local/tomcat/conf/tomcat-users.xml
<role rolename="manager-gui"/>
<role rolename="admin-gui"/>
<user username="tomcat" password="tomcat" roles="manager-gui,admin-gui"/>
</tomcat-users>
[root@centos7 bin]# vim /usr/local/tomcat/webapps/manager/META-INF/context.xml

　<!--<Valve className="org.apache.catalina.valves.RemoteAddrValve"
  allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
  -->

1.1.2 重启

[root@centos7 bin]# sh shutdown.sh 
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
[root@centos7 bin]# sh startup.sh 
Using CATALINA_BASE:   /usr/local/tomcat
Using CATALINA_HOME:   /usr/local/tomcat
Using CATALINA_TMPDIR: /usr/local/tomcat/temp
Using JRE_HOME:        /usr
Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
Tomcat started.
