vsftpd ：500 OOPS: cannot change directory:

用户昵称不能为空 2014-09-09 01:17:25

使用的是linux centos7，selinux已经关闭。
创建用户 xxx.com，指向目录/var/virtual/xxx.com，开启vsftpd，可以直接ftp登录。
修改目录 /var/virtual/xxx.com 的chown 为 xxx.com:apache，出现访问域名，提示403.
将chown apache: -R /var/virtual/xxx.com，访问正常，但是vsftpd就登录不了了，因为目录不是该用户的。

这样，我给个我的安装脚本给你看看，我们因为安全原因使用的是虚拟用户。

1、你是使用虚拟用户还是系统实际用户登录的 2、对应的权限设置，目录权限chmod

实际的登录用户，通过useradd 添加的用户。

我的selinux是完全关闭 disabled的，他说的那几个根本无法执行。当我把那个目录的所有者设置为当前用户的时候才可以访问的。 chown xxx.com -R /var/virtual/xxx.com 但是网站无法访问了提示403.
