Thu, 09 Apr 2026 17:42:26 +0000 https://bugs.horde.org/ticket/9738 Fatal error using localhost MySQL with port number Localhost with portnumber fatal error: During configuration you can enter 'localhost' as TCP MySQL host. If however you do not delete the port number this results in a fatal error and Horde4 will not start. If you have deleted the port number, saved the config, move to a different tab and change paramaters on that tab and again save the config, the default port number is again entered in the MySQL host tab and thus again results in a fatal error. Workaround: There is a simple workaround which if included in the installation documentation can avoid the issue. If instead of 'localhost' you enter the IP address 127.0.0.1 as the TCP host, you can leave the port number unchanged and all works fine. Solution: A more elegant solution would possibly be adding one line of code which behind the scenes changes or equates 'localhost' with the IP address 127.0.0.1 or simply neglects the port value in case of 'localhost' or '127.0.0.1' entry.

I tend to convert "localhost" to "127.0.0.1" automatically, because this is probably what most users intended, and the magic behavior of MySQL to use sockets if the host is "localhost" already caused many WTF moments for administrators. OTOH many admins and developers might already be aware of this behavior and could be using "localhost" intentionally.

Anybody having an opinion on this? Wed, 18 May 2011 16:23:34 +0000 https://bugs.horde.org/ticket/9738#t64811 Sounds okay to me.
