If you have been paying attention to nginx, you must know what the nginx software is for. If your website traffic is getting higher and higher, one server can no longer withstand traffic pressure, let's increase the number of servers for load. Website load can be achieved by buying hardware devices, such as F5, but the price ranges from hundreds of thousands to m

A brief introduction of LVSLVS is the short name of Linux virtual server, the Linux VM, a free software project initiated by Dr. Zhangwensong, and its official site is www.linuxvirtualserver.org. Now that LVS is already part of the Linux standard kernel, Before the Linux2.4 kernel, the use of LVS must be recompiled to support the LVS function module, but from the Linux2.4 kernel, has been completely built in the LVS function modules, no need to make any patches to the kernel, you can directly us

requires two features, the first being high performance, and the second being highly available.1. Test High PerformanceWhen the client uses the browser to open http://172.16.10.30/test.html, the browser displays information:Refresh and display the message:You can see that the cluster's load-balancing schedule takes effect to meet the high-performance requirements of the cluster.2.

The company recently had a project because users are concerned that a single machine can not afford to use the maximum number of users, the application cluster requirements. We designed the application cluster architecture according to the application situation. The architecture diagram is as follows: Features for deploying application clusters: 1.
