根据http://www.cnblogs.com/zzzhfo/p/6032095.html这个环境配置

  • 在web01和web02上配置基于域名的虚拟主机

web01

[root@web01 /]# mkdir -p /var/www/html/www
[root@web01 /]# mkdir -p /var/www/html/bbs
[root@web01 /]# echo "<h1>bbs.test.com<h1/>" > /var/www/html/bbs/index.html
[root@web01 /]# echo "<h1>www.test.com<h1/>" > /var/www/html/www/index.html
[root@web01 /]# vim /etc/httpd/conf/httpd.conf 
NameVirtualHost *:80    //设置虚拟主机监听地址
<VirtualHost *:80>
    DocumentRoot "/var/www/html/www"
    ServerName www.test.com
    ErrorLog "logs/www.test.com.error_log"
    CustomLog "logs/www.test.com.access_log" common
</VirtualHost>

<VirtualHost *:80>
    DocumentRoot "/var/www/html/bbs"
    ServerName bbs.test.com
    ErrorLog "logs/bbs.test.com.error_log"
    CustomLog "logs/bbs.test.com.access_log" common
</VirtualHost>

web02 （可使用scp同步到web02）

[root@web02 /]# mkdir -p /var/www/html/www
[root@web02 /]# mkdir -p /var/www/html/bbs
[root@web02 /]# echo "<h1>bbs.test.com<h1/>" > /var/www/html/bbs/index.html
[root@web02 /]# echo "<h1>www.test.com<h1/>" > /var/www/html/www/index.html
[root@web02 /]# vim /etc/httpd/conf/httpd.conf 
NameVirtualHost *:80
<VirtualHost *:80>
    DocumentRoot "/var/www/html/www"
    ServerName www.test.com
    ErrorLog "logs/www.test.com.error_log"
    CustomLog "logs/www.test.com.access_log" common
</VirtualHost>

<VirtualHost *:80>
    DocumentRoot "/var/www/html/bbs"
    ServerName bbs.test.com
    ErrorLog "logs/bbs.test.com.error_log"
    CustomLog "logs/bbs.test.com.access_log" common
</VirtualHost>

测试两台web的虚拟主机

[root@web_backup /]# vim /etc/hosts
192.168.119.130 www.test.com    bbs.test.com
[root@web_backup /]# curl www.test.com
<h1>www.test.com<h1/>
[root@web_backup /]# curl bbs.test.com
<h1>bbs.test.com<h1/>
[root@web_backup /]# vim /etc/hosts
192.168.119.133 www.test.com    bbs.test.com
[root@web_backup /]# curl www.test.com
<h1>www.test.com<h1/>
[root@web_backup /]# curl bbs.test.com
<h1>bbs.test.com<h1/>

测试：通过负载均衡器虚拟主机能否正常反问

修改/etc/hosts  地址改为Nginx负载均衡器的地址（lb）

[root@web_backup /]# vim /etc/hosts
192.168.119.128 www.test.com    bbs.test.com
[root@web_backup /]# curl bbs.test.com
<h1>www.test.com<h1/>
[root@web_backup /]# curl www.test.com
<h1>www.test.com<h1/>

 返回的结果都是第一个域名

 

通过 修改Nginx负载均衡器的配置文件/usr/local/nginx/conf/nginx.conf 在location 添加proxy_set_header Host $host;

[root@lb01 /]# vim /usr/local/nginx/conf/nginx.conf
worker_processes  1;
events {
    worker_connections  1024;
}
http {
    include       mime.types;
    default_type  application/octet-stream;
    sendfile        on;
    keepalive_timeout  65;

upstream web_pools {
    server 192.168.119.130:80 weight=5;
    server 192.168.119.133:80 weight=5;
    server 192.168.119.131:80 weight=5   backup;
}

    server {
        listen       80;
        server_name  www.test.com;
        location / {
            root   html;
            index  index.html index.htm;
            proxy_pass http://web_pools;
            proxy_set_header Host $host;
        }
        }
    }

 重启nginx服务

[root@lb01 /]# nginx -s stop
[root@lb01 /]# nginx 
[root@lb01 /]# netstat -anpt | grep nginx
tcp        0      0 0.0.0.0:80                  0.0.0.0:*                   LISTEN      2058/nginx

 

 测试

[root@web_backup /]# curl www.test.com
<h1>www.test.com<h1/>
[root@web_backup /]# curl www.test.com
<h1>www.test.com<h1/>
[root@web_backup /]# curl bbs.test.com
<h1>bbs.test.com<h1/>
[root@web_backup /]# curl bbs.test.com
<h1>bbs.test.com<h1/>
[root@web_backup /]# curl www.test.com
<h1>www.test.com<h1/>

 

 返回结果正常
