Nginx负载均衡

当用户访问nginx定制好的域名时，nginx通过转发到几台真实的站点，通过upstream实现

[root@centos7 vhost]# vim /usr/local/nginx/conf/vhost/load.conf

upstream www.tt.com

#自定义域名

ip_ash;

#保证同一个用户始终保持在同一台机器上,即当域名指向多个IP时，保证每个用户始终解析到同一IP server 192.168.3.74:80; server 192.168.3.83:80; #指定web服务器的IP

server

listen 80; server_name www.tt.com; location / { proxy_pass http://tt.com; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; }
