Nginx简单负载均衡配置,nginx负载均衡Nginx是由Igo

Nginx("engine x")是一个高性能的HTTP和反向代理服务器，也是一个IMAP/POP3/SMTP代理服务器。Nginx是由Igor Sysoev为俄罗斯访问量第二的Rambler.ru站点开发的，它已经在该站点运行超过两年半了。Igor将源代码以类BSD许可证的形式发布。

1、安装pcre库

tar jxvf pcre-7.9.tar.bz2

cd pcre-7.9/

./configure

make

make install

2、安装nginx

tar zxvf nginx-0.6.36.tar.gz

cd nginx-0.6.36/

./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module

make

make install

3、运行nginx

/usr/local/nginx/sbin/nginx -c /usr/local/nginx/conf/nginx.conf

4、配置nginx反向代理

loading.abc.com和loading.xyz.com域名均指向nginx所在的服务器IP，用户访问[url]http://loading.abc.com[/url]，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[url]http://loading.xyz.com[/url]，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 abc {

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 xyz {

server 192.168.1.7:8080;

server 192.168.1.7:8081;

server 192.168.1.7:8082;

}

server {

listen 80;

server_name loading.abc.com;

location / {

proxy_pass[url]http://abc[/url];

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 abc '$remote_addr - $remote_user [$time_local] $request '

'"$status" $body_bytes_sent "$http_referer" '

'"$http_user_agent" "$http_x_forwarded_for"';

access_log /www/logs/abc.log abc;

}

server {

listen 80;

server_name loading.xyz.com;

location / {

proxy_pass[url]http://xyz[/url];

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 xyz '$remote_addr - $remote_user [$time_local] $request '

'"$status" $body_bytes_sent "$http_referer" '

'"$http_user_agent" "$http_x_forwarded_for"';

access_log /www/logs/xyz.log xyz;

}
