configuration is simple. The server load can be pinged. the backend server status can be checked through the port, but url detection is not supported; 3. Anti-high concurrency, using the epoll network model to process customer requests; 4. Only HTTP and EMail are supported, and the application scope is relatively small; 5. nginx is mainly used for HTTP and reverse proxy servers, reducing system resource consumption. Four common algorithms: 1. RR: (default) Round

B domain name into the English site, which is almost impossible to achieve in the four-tier load balancer, And seven-tier load balancing can be based on the client access to different domain names to select the corresponding Web page for load balancing processing. Common seven-layer load balancer has haproxy, nginx and so on.Here is still a common example of TCP applications, because the load balancer to obtain the content of the message, so can only

Introduction: The difference between LVS and HaproxyLvs:1, strong anti-load capacity, is the work in the Network 4 layer on the distribution only, no flow generation;2, no flow, to ensure that the performance of the Equalizer IO will not receive the impact of large traffic;3, the application of a wide range, because LVS work in the 4 layer, so it can almost all applications to do load balancing4, the work is stable, because of its own resistance to load capacity is very strong, self has a comple

LB load Balancing clusters are divided into two categories: LVS (four floors) and Nginx or haproxy (seven layers). LVS is ip-based, and Nginx and Haproxy are based on applications. The client accesses the Web site by accessing the Distributor's IP. The distributor forwards the request to the corresponding machine on the back-end, depending on the type of request. load Balancing cluster with static and dynam

However, for MIS, data is often pushed from the server to the client. For example, when a user submits a new application, the administrator needs to approve the application. The solution is to "Persevere" the client asks the server if there are
