使用宝塔搭建的环境连接FTP报错：“数据 Socket 错误 连接已超时”错误
开放了21、22端口还是无法连接
因为宝塔的PureFtp还需要开放39000-40000端口
去安全组或防火墙中开放对应端口即可
SQL语句执行错误：SELECT * FROM emlog_sort where pid= ORDER BY sid ASC, taxis asc
You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ORDER BY sid ASC, taxis asc' at line 1
