The main implementation is a high-availability server Load balancer web server cluster, suitable for lamp architecture. The front end uses two servers as The lvs + keepalived load scheduler. N servers can be used as the apache + php application server in the middle, and the next two servers are used as the mysql high-availability dual-machine, finally, a virtual

First, the problems encounteredWhen we deploy a Web application with an IIS server, when many users have high concurrent access, the client responds very slowly and the customer experience is poor, because when IIS accepts a client request, it creates a thread that consumes large memory when the thread reaches thousands of. At the same time, because these threads are switching, the CPU usage is also high, which makes IIS more difficult to perform. So how do we solve this problem? Second, how t

multiple UDP sockets on the server and binds the same IP and port, and the client sockets for different source IPs and ports automatically load to different server sockets. In this way, if you want to take advantage of multi-CPU, you can pre-create multiple processes, each of which allocates a UDP socket to handle the sending and receiving of the data (the code implementation can pre-fork multiple processe
