通过设置访问密码查看Tomcat服务器运行状态

1. 安装tomcat
2. 设置访问manager用户名，密码

vim /usr/local/tomcat9/conf/tomcat-users.xml  # 设置访问manager用户名，密码
# 在倒数第二行增加如下内容
<role rolename="admin"/>
<role rolename="admin-gui"/>
<role rolename="admin-script"/>
<role rolename="manager"/>
<role rolename="manager-gui"/>
<role rolename="manager-script"/>
<role rolename="manager-jmx"/>
<role rolename="manager-status"/>
<user username="admin" password="abc123" roles="admin,manager,admin-gui,admin-script,manager-gui,manager-script,manager-jmx,manager-status" /> 

1. 设置允许连接的网络

vim /usr/local/tomcat9/webapps/manager/META-INF/context.xml
vim /usr/local/tomcat9/webapps/host-manager/META-INF/context.xml 

# 原有内容
<Context antiResourceLocking="false" privileged="true" >
  <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>

# 新增网络后的内容
<Context antiResourceLocking="false" privileged="true" >
  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1|192.168.0.*" />
  <Manager sessionAttributeValueClassNameFilter="java\.lang\.(?:Boolean|Integer|Long|Number|String)|org\.apache\.catalina\.filters\.CsrfPreventionFilter\$LruCache(?:\$1)?|java\.util\.(?:Linked)?HashMap"/>
</Context>
