nginx.conf负载均衡配置

负载均衡配置（nginx.conf文件）：

#user  nobody;
worker_processes  2;  


#错误日志存放路径  
#error_log  logs/error.log;  
#error_log  logs/error.log  notice;  
error_log  logs/error.log  info; 


#指定pid存放文件  
pid        logs/nginx.pid; 




events {  
    #使用网络IO模型linux建议epoll，FreeBSD建议采用kqueue，window下不指定。  
    #use epoll;  
      
    #允许最大连接数  
    worker_connections  2048;  
}

nginx命令：

nginx -s reload  ：修改配置后重新加载生效

nginx -s reopen  ：重新打开日志文件

nginx -t -c /path/to/nginx.conf 测试nginx配置文件是否正确

关闭nginx：

nginx -s stop  :快速停止nginx

nginx -s quit  ：完整有序的停止nginx

启动nginx:

nginx -c D:\Java\nginx\nginx-1.6.3\conf\nginx.conf

配置错误：

错误1：没有相应的文件夹（D:/resourecefile/images）

解决方法：添加相应的文件夹（D:/resourecefile/images）

错误2：nginx没有启动

解决方法：执行nginx.exe或命令提示符下执行 nginx -c D:\Java\nginx\nginx-1.6.3\conf\nginx.conf再执行nginx -s reload
