Nginx 简单的负载均衡配置示例

　www.s135.com 和 blog.s135.com 域名均指向 Nginx 所在的服务器IP。

　　用户访问http://www.s135.com，将其负载均衡到192.168.1.2:80、192.168.1.3:80、192.168.1.4:80、192.168.1.5:80四台服务器。

　　用户访问http://blog.s135.com，将其负载均衡到192.168.1.7服务器的8080、8081、8082端口。

　　以下为配置文件nginx.conf：

user www www;worker_processes 10;#error_log logs/error.log;#error_log logs/error.log notice;#error_log logs/error.log info;#pid logs/nginx.pid;#最大文件描述符worker_rlimit_nofile 51200;events { use epoll; worker_connections 51200;}http { include conf/mime.types; default_type application/octet-stream; keepalive_timeout 120; tcp_nodelay on; upstream www.s135.com { server 192.168.1.2:80; server 192.168.1.3:80; server 192.168.1.4:80; server 192.168.1.5:80; } upstream blog.s135.com { server 192.168.1.7:8080; server 192.168.1.7:8081; server 192.168.1.7:8082; } server { listen 80; server_name www.s135.com; location / { proxy_pass http://www.s135.com; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } log_format www_s135_com '$remote_addr - $remote_user [$time_local] $request ' '"$status" $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /data1/logs/www.log www_s135_com; } server { listen 80; server_name blog.s135.com; location / { proxy_pass http://blog.s135.com; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; } log_format blog_s135_com '$remote_addr - $remote_user [$time_local] $request ' '"$status" $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /data1/logs/blog.log blog_s135_com; }}
