Windows系统中配置Nginx负载均衡

Windows系统中配置Nginx详细步骤之负载均衡

A.下载nginxB.解压到C盘并开始配置nginx.conf,搭建负载均衡C.asp.net mvc代码D.配置的iis站点(多个文件夹的程序都是一样的；只是为了好测试是否实现了负载均衡的效果)E.想要的负载均衡效果F.nginx常用命令

A.下载nginx

下载路径：http://nginx.org/en/download.html 这里下载的版本：nginx-1.10.3

B.解压到C盘并开始配置nginx.conf,搭建负载均衡

解压文件

启动nginx

检查nginx是否成功

F.nginx常用命令

nginx -s quit 优雅停止nginx，有连接时会等连接请求完成再杀死worker进程 start nginx 开启nginx服务器 nginx -s reload 优雅重启，并重新载入配置文件nginx.conf nginx -s stop 关闭nginx服务 nginx -s reopen 重新打开日志文件，一般用于切割日志 nginx -v 查看版本 nginx -t 检查nginx的配置文件 nginx -h 查看帮助信息 　 nginx -V 详细版本信息，包括编译参数 nginx -c filename 指定配置文件
