). Before we introduced the cluster, our first query process was roughly the following: requesting the data layer and passing the necessary library-differentiated fields (typically user_id). The data layer carries out data operations within the defined DB based on the differentiated field route to the specific DB.

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

each of the four servers. The remaining IP address is called "virtual IP Address", which is used to share the two Server Load balancer nodes. Architecture details The configuration information is as follows: Server Load balancer Node 1: lb1.mytest.com (lB1); IP Address: 192

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.

Some time recently, we started touching on load balancing, from hardware F5 to Citrix Netscalar. However, because the hardware configuration is not complicated, but the expensive price also makes the general user prohibitive (a hundred thousand of to hundreds of thousands of), so can only turn to nginx,squid this kind has the reverse proxy function software. Fortunately its settings are not very troublesome

packets into small data segments and distribute them to multiple parallel lines. It can also dynamically allocate dialing lines based on the current Link Utilization. Although the speed is very slow, because packet segmentation and additional buffering increase latency, it can run well on low-speed lines.The link aggregation system increases the complexity of the network, but also improves the reliability of the network, so that people can use redundant routes on the lines of key LAN segments s

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
