Nginx main configuration parameters, Nginx configuration website, and nginx Parameters

Nginx main configuration parameters, Nginx configuration website, and nginx Parameters
1. Detailed description of parameters in the main configuration file

A. Install nginx in Linux. Blog address: http://www.cnblogs.com/cindy-cindy/p/6847499.html

B. after Nginx is installed, a corresponding installation directory is displayed, which contains nginx. confg is the main configuration file of nginx. The main configuration file of nginx is divided into four parts: main (global configuration), server (host configuration), and upstream (server Load balancer settings) and location (the URL matches the settings of a specific location). The relationship between these four is: server inherits main, location inherits server, and upstream neither inherits other settings nor is inherited.

C. nginx is a proxy server. Generally, websites cannot be deployed under Nginx. For example, Java Web programs developed using Java are deployed under tomcat, then, point the website address to tomcat using the Nginx proxy.

3. Nginx proxy website

A. I deployed a javaweb project under tomcat. the IP address of the server installed by tomcat is 192.168.37.136. The access address of the deployed project under tomcat is http: // 192.168.37.136: 8080/lywh/

B. I have successfully installed Nginx under the server whose IP address is 192.168.37.htm.

C. How can I use the Nginx proxy for the website deployed under tomcat ?, Modify the Nginx configuration file and run the command vim/usr/local/nginx/conf/nginx. conf.

D. After Nginx. conf is configured, close the file and run the command to check whether the configuration file is faulty. If yes, check whether the configuration is faulty.

　　　　

E. Check if OK is returned, it means there is no error in modifying the file. Restart Nginx at this time. Command:/usr/local/nginx/sbin/nginx-s reload

F. The website after the last access to the proxy, http: // 192.168.37.htm/lywh, indicates that the website has been accessed by the Proxy:

　　　　

 

This note has been written. If you have any questions, you can discuss it with me. I also write notes while learning. If there is any error, please let me know.

I wish you a happy New Year and a smooth journey tomorrow.
