apache 反向代理设置
参考
http://helpful.knobs-dials.com/index.php/Apache_config_and_.htaccess_-_URL_rewriting#Server_redirecting.2Fproxying_.28internal.29
http://shiningray.cn/proxypass-directive-in-apache.html
不能再htaccess中设置proxypass。必须在Context:serverconfig,virtualhost,directory
见
http://stackoverflow.com/questions/12808506/can-proxypass-and-proxypassreverse-work-in-htaccess
如果在htaccess中设置，页面会提示500servererror错误。
且会在error.log中报错，提示“proxpassnotallowinhtaccess”
查看apache错误日志
tail/var/log/apache2/error.log
因此需要到vhost文件中设置。
添加
ProxyRequests Off
<Proxy *>
Order Deny,Allow
Allow from all
</Proxy>
ProxyPass /log http://ifeng.com
ProxyPassReverse /log http://ifeng.com这样，当域名+/log访问就会显示www.ifeng.com的内容了。
修改了vhost文件必须reload才能生效。
reloadapache命令：
sudo/etc/init.d/apache2reload
在window上试了，但是是直接跳转到ifeng.com。url变了。不知道为什么。同样开启了
proxy,proxy_http的功能。
设置如下
<VirtualHost *:80>
ServerAdmin [email protected]
DocumentRoot "E:/wamp/www/it-os-moreversus-cms"
ServerName moreversus-cms-local
ErrorLog "logs/dummy-host2.example.com-error.log"
CustomLog "logs/dummy-host2.example.com-access.log" common
ProxyRequests Off
<Proxy *>
Order Deny,Allow
Allow from all
</Proxy>
ProxyPass /log http://ifeng.com
ProxyPassReverse /log http://ifeng.com
</VirtualHost>也可以不修改vhost，只修改htaccess設置代理。需要給RewriteRule添加[P]proxy的設置。
