Nginx 配置负载均衡

1：接上一篇博客：Nginx 源码安装

http://www.cnblogs.com/xiaoit/p/4062458.html

2：准备另外两台相同的配置机器

搭建Nginx的服务器主：101.69.178.208

负载均衡机器Nginx1:101.69.178.219

负载均衡机器Nginx2:61.153.100.239

3：查看主服务器上nginx.conf

cd /gechong/ruanjian/Nginx/conf

新装完Nginx的conf文件如下：

#user  nobody;
worker_processes  1;

events {
    worker_connections  1024;
}

http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;
	
    server {
        listen       80;
        server_name  localhost;


        location / {
            root   html;
            index  index.html index.htm;
        }

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

    }

}

做如下调整

#user nobody;
worker_processes 1;

#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid logs/nginx.pid;

events {
worker_connections 1024;
}

http {

upstream 101.69.178.208 {
server 61.153.100.239:80;
server 101.69.178.219:80;
}

include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;

server {
listen 80;
server_name 101.69.178.208;

location / {
# root html;
# index index.html index.htm;
#}
proxy_pass http://101.69.178.208;
proxy_set_header Host $host;
proxy_set_header X-Real-IP $remote_addr;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}

}
}

4：修改Nginx1和Nginx2机器上的nginx.conf 配置文件

cd /gechong/ruanjian/Nginx/conf

#user nobody;
worker_processes 1;

#error_log logs/error.log;
#error_log logs/error.log notice;
#error_log logs/error.log info;

#pid logs/nginx.pid;

events {
worker_connections 1024;
}

http {

include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;

server {
listen 80;
server_name 101.69.178.208;

location / {
root html;
index index.html index.htm;
}

error_page 500 502 503 504 /50x.html;
location = /50x.html {
root html;
}

}
}

5：简单修改index.html以区别两台机器

6：测试负载均衡

浏览器访问：http://101.69.178.208/

7：测试成功。。。

但是单独拿出来一台机器做转发，感觉有点浪费资源，下一节将说明如何配置转发机器也提供访问。
