apache的proxy代理总访问后端web的第一个虚拟主机

回复收藏

虚拟主机代理 web proxy 四期视频

问题，如题。怎么折腾都是一直访问第一个虚拟主机，后来找到问题所在。是我配置的不对。错误配置是这样的：

ServerName www.test.com
CustomLog "/dev/null" combined
ProxyRequests Off
Order deny,allow
Allow from all
ProxyPass / http://192.168.13.111/
ProxyPassReverse / 192.168.13.111/

问题出在了： ProxyPass / http://192.168.13.111/
要改成这样： ProxyPass / http://www.test.com/

所以正确的配置是这样的：

ServerName www.test.com
CustomLog "/dev/null" combined
ProxyRequests Off
Order deny,allow
Allow from all
ProxyPass / http://www.test.com/
ProxyPassReverse / 192.168.13.111/

另外需要注意的是，需要在/etc/hosts 中加一条记录
192.168.13.111 www.test.com

我按您的方法时

<VirtualHost *:80>
ServerAdmin webmaster@dummy-host.example.com
DocumentRoot "/usr/local/apache2/htdocs/"
ServerName dummy-host.example.com
ServerAlias www.dummy-host.example.com
</VirtualHost>
<VirtualHost *>
ServerName www.discuz.com
CustomLog "/dev/null" combined
ProxyRequests Off
<Proxy *>
Order deny,allow
Allow from all
</Proxy>
ProxyPass / http://www.discuz.com/
ProxyPassReverse / 192.168.0.105/
</VirtualHost>

出现如下警告
# apachectl -t
[Mon Feb 01 17:15:38 2016] [warn] NameVirtualHost *:80 has no VirtualHosts
Syntax OK
# apachectl graceful
[Mon Feb 01 17:16:12 2016] [warn] NameVirtualHost *:80 has no VirtualHosts

访问的web是proxy服务器上的默认虚拟主机

把改为时，没有报错
# apachectl -t
Syntax OK
# apachectl restart

但是访问结果是500

问题解决了，一开始我只安装了 mod_proxy.c prox_util.c 这两个模块，后来查了下是下面几个也都要装，然后用的是

#/usr/local/apache2/bin/apxs -i -c -a mod_proxy.c prox_util.c
#/usr/local/apache2/bin/apxs -i -c -a mod_proxy_http.c
#/usr/local/apache2/bin/apxs -i -c -a mod_proxy_connect.c
