Both LVS and Nginx can be used as multi-host load solutions. They have advantages and disadvantages. in the production environment, you need to analyze the actual situation and make use of it.First of all, I would like to remind you that technology is not a cloud, and my cloud is your cloud. At the same time, we should not be too conservative, too confident in the old method and wait for others to help you with the advance test. It is a good habit to

project, cost-effective is much higher than F5, commercial first choice! But in general this phase of the relevant talent to keep up with the business, so the purchase of commercial load balance has become the only way. The ability and quantity of talent is also increased, at this time, regardless of the development of customized products for their own, and reduce the cost of open source LVs, has become the first choice, then LVS will become the main

efficient than nginx with better load-balancing speed.6. Haproxy can load-balance MySQL and Detect and load-balance the DB node in the backend.7. Support Load Balancing algorithm: Round-robin (round robin), Weight-round-robin (with weighted rotation), source (original address hold), RI (request URL), Rdp-cookie (based

client.Advantage: You can increase the hit rate of the cache (the same URL will be assigned to the same server as far as possible);Disadvantage: It is possible to cause a single point bottleneck (weights invalid).4, according to the parameters in the request URL, balance Url_param.The hashed operation is matched according to the specified URL parameter.Pros: More flexible, can increase the hit rate of the cache (the same specified parameters will be allocated to the same server asService);Disad

there is a machine down, it is only one of the db n one of the data can not access it, which we can accept, at least more than before the segmentation of the situation is much better, not the entire DB can not access. In general applications, such machine failure caused by the data is not accessible is acceptable, assuming our system is a high-concurrency e-commerce site? The economic losses caused by single-node machine outages are very serious. In other words, there is still a problem with ou
