Ngigx + Tomcat configure static/dynamic separation, Server Load balancer, and ngigxtomcat

Since the company used Ngnix, I felt a little curious about Nginx, So I studied it.

My version used in windows is nginx-1.8.1:

1. Start Ngnix

Double-click nginx-1.8.1. nginx.exe in the folder. If two nginx processes exist in the task manager, the startup is successful!

2. Common Ngnix commands

Forced nginx-s stop Shutdown
Nginx-s quit Security disabled
When nginx-s reload changes the configuration file, restart the nginx working process and the configuration file takes effect.
Nginx-s reopen open log file

3. Nginx Configuration

The following configuration combines the online information and writes it down to prevent you from forgetting it.
