First of all, nginx needs to know that forward proxy, reverse proxy

Forward proxy: to access GG, you definitely need a FQ at this time, then find an agent that can access a foreign country, and then the agent accesses the GG and passes the data to us. At this time, the position of the agent is the forward agent.

Reverse proxy: for example, when accessing a treasure, the agent is the server. After receiving the nginx, you distribute the rules to the back-end business processing server for processing.

Environment

Tomcat8080 tomcat8081

Nginx acts as a reverse proxy

Nginx configuration this configuration is in the http tag

Upstream myserver {server 192.168.4.4 server 8080 weight=5 max_fails=2 fail_timeout=3; server 192.168.4.4 weight=5 max_fails=2 fail_timeout=3;} server {listen 81; location / {root html; index index.html index.htm; proxy_pass http://myserver;}}

Visit the address of 192.168.4.4 tomcat 81 and access different VLANs according to the scheduling algorithm.

Scheduling algorithm:

To train in rotation.

Weight set a weight value

Ip_hash haship address

Url_hash hash url

Fair intelligent scheduling, which dynamically balances the time from request processing to response from the back-end server.

Each has its own advantages, and the best one is fair.
