closed for each request. The default listening port is 8007. 3-2 ajp13 type Worker attributes: When ajp13 type worker is working, the ajpv13 protocol based on TCP/IP socket is forwarded to the Tomcat worker "out-of-process. The ajpv13 protocol is significantly different from the ajpv12 protocol: * Ajpv13 has a richer binary protocol. it uses the frequently used string encoding method to compress the request data. * Ajpv13 reuses opened sockets and retains these opened sockets to handle future r

Many websites do not need a large scale at the beginning, but as a website designer, expansion must be taken into account from the very beginning to build a highly scalable architecture. The so-called scalability means that the system can improve the carrying capacity of the system through scale expansion. After all, the vertical expansion of the server itself will soon be restricted, and the single machine will soon be unable to meet our needs, therefore, this capability is often achieved by ad

for providing us with such powerful and practical open-source software.LVS features:1. Strong anti-load ability, working on Layer 4 of the network for distribution only, no traffic is generated, this feature also determines its strongest performance in the load balancing software;2. Low configuration, which is a disadvantage and an advantage. Because there is no configuration item, there is no need for too

is relatively large. Can bear high load pressure and stability, in the case of hardware is not bad generally can support tens of thousands of times the concurrency, the load is relatively smaller than LVS. Nginx can detect the internal failure of the server through the port, such as the status code returned by the server processing, timeout and so on, and wi

Reverse proxy Load Balancer ApacheOne, reverse proxy1.1 Introduction Reaction AgentThe reverse proxy method refers to a proxy server that accepts connection requests on the Internet, then forwards the request to a server on the internal network and returns the results from the server to the client requesting the connection on the Internet, Reverse. At this point the proxy server appears as a reverse proxy s
