Apache implements the Load balancer parameter "proxypass/balancer://proxy/", where "Proxypass" is the command that configures the virtual server, "/" represents the URL prefix for sending Web requests, such as: http://myserver/Or HTTP://MYSERVER/NODE1, these URLs will conform to the above filter conditions, "

Heartbeat uses the virtual IP address ing technology to implement the function of transparent switching between master and slave servers to the client. However, a single heartbeat cannot provide robu

Haproxy provides high availability, Load Balancing and proxies based on TCP and HTTP applications that support Virtual Host , it is a free, fast and reliable solution. Haproxy is especially useful for Web sites that are heavily loaded, and often require session-hold or seven-tier processing. Experiment (I.)Experimental purpose: Using Haproxy to do load balancing

Introduction to the Basic overviewLVS is a load balancing software that works at the transport level and consists of two components of the IPVSADM and kernel space of the user space Ipvs. The Ipvsadm is a command-line tool for user space, primarily for manag

I used nginx to implement the website load balancing test. In windows, IIS performs load measurement. If your website traffic (pv) is getting higher and higher, and one server is no longer able to withstand the traffic pressure, increase the number of WEB servers for load. Website load can be achieved by buying hardw
