visit: Http://192.168.2.150:8888/stats4. Test: As we bind the loopback interface to the 127.0.0.1:8081 port on the native 127.0.0.1:80 port, the last time we installed the httpd, the binding is 127.0.0.1:8081http://www.cnblogs.com/ super-d2/p/4134467.html Access http://192.168.2.137:8081/can see this without configuring Haproxy before we visit http://192.168.2.137:80/is inaccessible, Because this service is not available on port 80, if we start haproxy now, we can access it again: through Haproxy we implement proxy access http://192.168.2.137:80/
