SQLSTATE[HY000] [2003] Cant connect to MySQL server

今天要连远程数据库,结果PHP报错

Fatal error: Uncaught exception 'PDOException' with message 'SQLSTATE[HY000] [2003] Can't connect to MySQL server on '192.168.1.252' (13)' in /web/miophp/Etc/geter/Action/IndexAction.php:7 Stack trace: #0 /web/miophp/Etc/geter/Action/IndexAction.php(7): PDO->__construct('mysql:dbname=ba...', 'mio', 'miomio', Array) #1 /web/miophp/Etc/geter/Action/Action.php(11): IndexAction->index() #2 [internal function]: Action->ActionInit('index') #3 /web/miophp/Core/core.php(36): call_user_func(Array, 'index') #4 /web/miophp/Mio.php(30): include('/web/miophp/Cor...') #5 /web/admin/mio/index.php(20): require('/web/miophp/Mio...') #6 {main} thrown in /web/miophp/Etc/geter/Action/IndexAction.php on line 7

 

我以为是程序有问题 查了半天结果是selinux
