nginx负载均衡篇二、nginx配置

时间:2015-05-22

如果不知道在Linux下如何安装nginx请参考前一篇文章。

nginx负载均衡的配置较apache要简单许多,这里用nginx做负载均衡将不再描述tomcat集群的配置,如果对tomcat集群配置有不懂的地方,请参考Apache反向代理结合Tomcat集群来实现负载均衡(三)、tomcat集群文章进行配置。下边进入正题,开始配置nginx负载均衡。

先来看下nginx的完全配置:

#user  nobody;  
worker_processes  1;  
      
#error_log  logs/error.log;  
#error_log  logs/error.log  notice;  
#error_log  logs/error.log  info;  
      
#pid        logs/nginx.pid;  
      
      
events {  
    worker_connections  1024;  
}  
      
      
http {  
    include       mime.types;  
    default_type  application/octet-stream;  
      
    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '  
    #                  '$status $body_bytes_sent "$http_referer" '  
    #                  '"$http_user_agent" "$http_x_forwarded_for"';  
      
    #access_log  logs/access.log  main;  
      
    sendfile        on;  
    #tcp_nopush     on;  
      
    #keepalive_timeout  0;  
    keepalive_timeout  65;  
      
    #gzip  on;  
          
    upstream tom_server {
