Tomcat to form a cluster, load balancing can be achieved, V1.0 and V2.0 May show a more detailed configuration of the upstream that makes up the Tomcat cluster, and can refer to the official documentation, with Nginx forwarding requests to the servers in the Tomcat cluster by default, as well as other ways such as Ip_hash. ///////////////////////////////////////
On the weekend, I was wondering, "can I use nginx to load balance multiple Google app enine (Gae) applications ?" It's interesting to think about it. Let's try it out, but this is the first time I 've used nginx for load balancing. It's just a bit of fun, and I don't have th

In the first example, server 127.0.0.1:808 is the server address, and the latter weight=1 is the weight. You can write more than one. Pro Test, one of the cluster is bad, does not affect the system operation. For more polling rules, you can refer to more information on the Web. Not much to say here. As for how to use it?

The principle of using nginx to complete this task is roughly the same, but nginx can only perform load balancing on http and mail, which is quite limited, but it supports regular expressions well! The following describes the experiment:

Nginx do reverse proxy, the back-end host has more than one, you can use upstream to define a back-end host pool, in the reverse proxy directly using the host pool name. In upstream, we can define load balancing scheduling algorithm, weight, health status detection and other parameters.
For example:
