haproxy appliance

Hproxy provides high availability, load balancing, and reverse proxies based on TCP and HTTP applications, especially for those web sites that are heavily loaded, which typically require session hold or seven-tier processing. Haproxy runs on the current hardware, fully supports tens of thousands of concurrent connections, and its operating mode makes it easy and secure to integrate into the architecture, while protecting your Web server from being exp

PS: nginx/LVS/haproxy is currently the most widely used three load balancing software. I have implemented these software in multiple projects. I have referenced some materials and combined some of my experience in using it, to sum up. Generally, Server Load balancer uses different technologies at different stages as the website scale increases. Specific Application requirements have to be analyzed. For small and medium-sized web applications, such a

Preface: We KnowTomcat+nginxLoad Balancing cluster,LVsLoad Balancing clusterAndHaproxyto build a cluster, these three clusters are comparedLVsthe performance is the best, but the building is complexNginxof theUpstreamThe module supports clustering, but there is not much fault checking on the nodes of the cluster, and no performanceHaproxyWell, so it should be saidHarpoxyis also very good. So then we started using haproxy to build the cluster. One, top

Project needs to build RABBITMQ high-availability cluster, recently in the learning and building process, recorded here can communicate with everyone (here is just a record of their own building process after learning, many of the principles of things not in detail).

Implementation requirements:Using Haproxy To do load balancing, manually add or remove node server information in the configuration file, it is more troublesome. Collect the information that needs to be registered to Consul as the Haproxy node server through Registrator, and then register to Consul Key/value . Consul-template go to Consul key/value to read the information and then automatically modify the

The main goal of this project are to provide simple and robust facilities (capability) for loadbalancing and high-availability to Li Nux system

Shell practice: use shell to automatically receive and load the haproxy configuration file, so that the configuration takes effect. haproxy automatically receives the configuration and loads 002. Introduction to the background receiving configuration process: 0031. It is a while 1 background process 0042. Currently, it is a 30 s check. Is there any new configuration? If yes, continue. If not, rest for 30 s.
