环境介绍
192.168.127.131 nginx负载均衡 兼web服务器
192.168.127.130 nginx负载均衡 兼web服务器
每台服务器上面有两个web站点分别是
www.123.com
www.hu.com
说明:
准备用dns轮询解析来实现负载均衡,并且在两台server上面还同时启用了Nginx负载均衡,两台服务器是互为负载。前提是两台web服务端的网站内容一致。
配置过程:
在130负载均衡上面的操作:
在 上面编辑一个配置文件 vi /usr/local/nginx/conf/vhost/ld.conf
##www.123.com
upstream 123{ server 192.168.127.130:81; server 192.168.127.131:81 ; ip_hash; } server { listen 80; server_name www.123.com; location / { proxy_pass http://123/; proxy_set_header Host $host; } } upstream hu { server 192.168.253.131:82; server 192.168.253.130:82; ip_hash; } server { listen 80; server_name www.hu.com; location / { proxy_pass http://hu/; proxy_set_header Host $host; }

更改 nginx负载服务器上面各个web主机的默认端口
server { listen 192.168.127.130:82; server_name www.hu.com; index index.html index.htm index.php; root /usr/local/nginx/html; location ~ \.php$ { include fastcgi_params; fastcgi_pass unix:/tmp/php-fcgi.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name; } }
―――――――――――――――――――――――――――――――――――――――――――――
server { listen 192.168.127.130:81 ; server_name www.123.com; index index.html index.htm index.php; root /data/www2; location ~ \.php$ { include fastcgi_params; fastcgi_pass unix:/tmp/php-fcgi.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /data/www2$fastcgi_script_name; } }
131上面的配置:
server { listen 192.168.127.131:81 ; server_name www.123.com; index index.html index.htm index.php; root /data/www2; location ~ \.php$ { include fastcgi_params; fastcgi_pass unix:/tmp/php-fcgi.sock; fastcgi_index index.php; fastcgi_param SCRIPT_FILENAME /data/www2$fastcgi_script_name; } }

同样的在 上面编辑一个配置文件 vi /usr/local/nginx/conf/vhost/ld.conf
##www.123.com
upstream 123{ server 192.168.127.130:81; server 192.168.127.131:81 ; ip_hash; } server { listen 80; server_name www.123.com; location / { proxy_pass http://123/; proxy_set_header Host $host; } } upstream hu { server 192.168.253.131:82; server 192.168.253.130:82; ip_hash; } server { listen 80; server_name www.hu.com; location / { proxy_pass http://hu/; proxy_set_header Host $host; }
最后分别启动nginx服务并查看端口是否正常启动
测试:分别在两个网站的目录里添加1.txt测试文件,里面写上不同的内容然后用浏览器访问 www.hu.com/1.txt,刷新几次
同样的,www.123.com/1.txt也是这样
