Nginx反向代理多虚拟主机代理

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/www

[root@web01 /]# mkdir -p /var/www/bbs

[root@web01 /]# echo "<h1>bbs.test.com<h1/>" > /var/www/bbs/index.html

[root@web01 /]# echo "<h1>www.test.com<h1/>" > /var/www/www/index.html

[root@web01 /]# vim /etc/httpd/conf/httpd.conf

NameVirtualHost *:    //设置虚拟主机监听地址

<VirtualHost *:>

    DocumentRoot "/var/www/www"

    ServerName www.test.com

    ErrorLog "logs/www.test.com.error_log"

    CustomLog "logs/www.test.com.access_log" common

</VirtualHost>

<VirtualHost *:>

    DocumentRoot "/var/www/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/www

[root@web02 /]# mkdir -p /var/www/bbs

[root@web02 /]# echo "<h1>bbs.test.com<h1/>" > /var/www/bbs/index.html

[root@web02 /]# echo "<h1>www.test.com<h1/>" > /var/www/www/index.html

[root@web02 /]# vim /etc/httpd/conf/httpd.conf

NameVirtualHost *:

<VirtualHost *:>

    DocumentRoot "/var/www/www"

    ServerName www.test.com

    ErrorLog "logs/www.test.com.error_log"

    CustomLog "logs/www.test.com.access_log" common

</VirtualHost>

<VirtualHost *:>

    DocumentRoot "/var/www/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  ;

events {

    worker_connections  ;

}

http {

    include       mime.types;

    default_type  application/octet-stream;

    sendfile        on;

    keepalive_timeout  ;

upstream web_pools {

    server 192.168.119.130: weight=;

    server 192.168.119.133: weight=;

    server 192.168.119.131: weight=   backup;

}

    server {

        listen       ;

        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:                  0.0.0.0:*                   LISTEN      /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
