Detailed Ngigx+tomcat configuration static and dynamic separation, load balancing _nginx

Because the company used Ngnix, for just contact Nginx, feel a little curious, so studied the next.

The version I use under Windows is nginx-1.8.1:

1. Start Ngnix

Double-click Nginx.exe in the nginx-1.8.1 folder to enable success when there are two Nginx processes in Task Manager!

2. Ngnix Common Commands

• Nginx-s stop forced shutdown
• Nginx-s quit safe shutdown
• Nginx-s Reload Change the configuration file, restart the Nginx worker process, when the configuration file comes into effect
• Nginx-s Reopen open log file

3. Nginx Configuration

The following configuration synthesizes the information on the net, jot down, prevent oneself to forget.
