Nginx load balancing configuration

: This article mainly introduces nginx server load balancer configuration. if you are interested in the PHP Tutorial, refer to it. I. INTRODUCTION

Tomcat has low performance when handling dynamic requests in high concurrency environments, but is more vulnerable to processing static pages. Although the latest version of Tomcat supports epoll, it is much better to process static pages through Nginx than to process static pages through Tomcat.

II. download and install (take windows as an example)

2. directory structure

Nginx-| _ conf configuration directory | _ contrib | _ docs document directory | _ logs log directory | _ temp temporary file directory | _ html static page directory | _ nginx.exe main program

III. start and stop the nginx service

Cmd enter the nginx decompression Directory

Run start nginxto start the service (nginx nginx.exe)
We recommend that you use the first method,
The other two methods keep your cmd window in the running state and do not support other command operations.

Run nginx-s stop to stop the nginx service.

Run nginx-t to check whether the nginx configuration file is correct.

IV. nginx main configuration file nginx. conf

5. load balancing weight configuration

    upstream localhost {      server localhost:8080 weight=5;      server localhost:9091 weight=1;     }

'). AddClass ('pre-numbering '). hide (); $ (this ). addClass ('Has-numbering '). parent (). append ($ numbering); for (I = 1; I <= lines; I ++) {$ numbering. append ($ ('

'). Text (I) ;}; $ numbering. fadeIn (1700) ;}) ;}; script

The above introduces the nginx server load balancer configuration, including some content, hope to be helpful to friends who are interested in the PHP Tutorial.
