environment, we announce that different Tomcat workers serve different exploitation services. Of course, developers in the development environment share the same web server, but each Tomcat worke serves its developers. * We define their respective virtual hosts in different Tomcat processes, so that different companies can apply their respective web sites so that their web sites can be fairly separated. * We provide the

Nginx Server Load balancer dual-host High Availability If the Web server cluster is used as a city pool, the load balancing server is equivalent to the city gate, and its importance is self-evident. If the "City Gate" is closed, the access to the outside world will be broken. If a server is balanced, when the server fails, the whole website will be inaccessible.

environment, in order to easily automatically load each server to the host environment, we can first configure each server according to the load balancing configuration steps, in all the configuration processes, except for using the common virtual IP address, other settings should be selected according to the configuration requirements, but must follow 1 ~ The 3

I. Introduction of LVSLVS is a short name for Linux virtual server, the Linux web, is a free software project initiated by Dr. Zhangwensong and is now part of the Linux standard kernel. LVS is a TCP/IP-based load balancing technology that has high forwarding efficiency and the ability to process millions of concurrent connection requests.The IP load balancing tec

problem, unless the entire group of machines are all down, but considering that such a thing happens very small (unless it is a power outage, Otherwise it is not easy to happen). Before we introduced a cluster, our first query process was roughly the following: requesting the data tier and passing the necessary library-differentiated fields (typically user_id)? The data layer is based on a differentiated field route to a specific db. Data operations are performed within this deterministic db. T
