$CATALINA_HOME/webapps/manager/META-INF/context.xml 和$CATALINA_HOME/webapps/host-manager/META-INF/context.xml 
这两个文件，全部修改 RemoteAddrValve 的值：

<!-- RemoteAddrValve的原始值 -->
 <Valve className="org.apache.catalina.valves.RemoteAddrValve" 
     allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
<!-- RemoteAddrValve修改后的值（其实就是释放所有IP的访问权限） -->
 <Valve className="org.apache.catalina.valves.RemoteAddrValve" 
     allow="\d+\.\d+\.\d+\.\d+" />
