LuManager FTP不能登录，报错：530 Login authentication failed

LuManager 的Pure-ftpd一直不能登录，今天准备测试一下看！

FlashFXP登录提示530 Login authentication failed的用户认证错误。我确信我在后台建立的FTP用户名和密码不会错，所以肯定是程序上的问题，然后我查看了linux日志文件：[separator]
[code]
[root@server1 log]# cat /var/log/messages

我用的是CentOS6.0+LuManager 1.1.9

一般默认安装MYSQL的话，mysql.sock的位置应该在/var/lib/mysql/mysql.
sock但是LuManager 中mysql.sock的默认位置在 /tmp/mysql.sock
Pure-ftpd的MYSQL配置文件在/usr/local/pureftpd/pureftpd-mysql.conf中
确保mysql.sock的正确位置
[code]MYSQLSocket     /tmp/mysql.sock[/code]
然后
[code]pureftpd-restart[/code]
重启Pure-ftpd
我解决了FTP不能登录的问题！

另外，官方介绍这是一个bug,需要SSH手动重启Pure-ftpd，上面我已经手动重启过了，所以没再去做测试。
