未知的MySQL服务器主机

Question

更改php verison后出现以下错误

Warning: mysqli::mysqli(): (HY000/2005): Unknown MySQL server host 
'clouddb.myhost.gr:3306' (2) in 
/var/www/vhosts/mywebside.gr/httpdocs/system/library/db/mysqli.php on 
line 7Warning: DB\MySQLi::__construct(): Couldn't fetch mysqli in 
/var/www/vhosts/mywebside.gr/httpdocs/system/library/db/mysqli.php on 
line 10Warning: DB\MySQLi::__construct(): Couldn't fetch mysqli in 
/var/www/vhosts/mywebside.gr/httpdocs/system/library/db/mysqli.php on 
line 10 .   

我无法理解问题是什么

Answer 1

你可能会一起传递clouddb.myhost.gr:3306，在mysqlcli上，端口有自己的参数：

mysql:host=clouddb.myhost.gr;port=3306;
