In the production environment, the MongoDB shards are built, providing three mongos interfaces. However, there is no failover mechanism in MongoDB, the official recommendation is to deploy MONGOs and application servers together, multiple application servers will deploy multiple MONGOs instances, which is inconvenient. Check it out, there are several ways to make these three mongos interfaces available, reducing the pressure on a single interface. Commonly used are LVS and

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).

The general use of load balancing is to use different technologies depending on the stage of the site's ascent. Specific application needs to be specific analysis, if it is small and medium-sized Web applications, such as the daily PV less than 10 million, with Nginx can be completely; if there are many machines, you can use DNS polling, LVS consumes more machines or more, large web sites or important services, and the server is relatively long, You can consider using LVS.One is through the hard

Haproxy is especially useful for Web sites that are heavily loaded, which typically require session maintenance or seven-tier processing. Haproxy is running on the current hardware and can support tens of thousands of concurrent connections altogether. and its operating mode makes it easy and secure to integrate into your current architecture while protecting your Web server from being exposed to the networ

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.
