discuz7.2版本与ss后台整合的时候，总是提示论坛路径设置错误，打开SS的后台admin_bbs.php文件，看了之后发现，原来ss是通过读取你设置的URL加一个默认文件的内容，通过远程下载方式，如果下载到的内容的长度大于100，则认为正确，小于则认为错误，解决办法很简单，打开ss的admin_bbs.php文件，将以下代码：
$_SC['bbsurl'] = trim($_POST['bbsurl']);

$txt = sreadfile($_SC['bbsurl'].'/viewthread.php', 'r', 1);
if(strlen($txt) < 100) {
   showmessage('bbs_url_error', CPURL.'?action=bbs&error=bbsurl');
}
替换为：
$_SC['bbsurl'] = trim($_POST['bbsurl']);
//echo "<script>alert('".$_SC['bbsurl']."');</script>";
$txt = sreadfile($_POST['bbsurl'].'/index.php', 'r', 1);
if(strlen($txt) < 100) {
   showmessage('bbs_url_error', CPURL.'?action=bbs&error=bbsurl');
}
 

 在本地电脑上测试一个php整站程序，配置了vhost中conf文件后重启nginx报错：

root@ubuntu:/home/meituge
# /etc/init.d/nginx.sh

最后发现原来是nginx重复重启。自己占用了端口。 解决方法  killall -9 nginx 杀掉nginx 进程  然后重启就行了。
/etc/init.d/nginx.sh 搞定。
