What is the error you are getting ?

If you want to connect through unix socket, you should leave hostname empty.
If you set it to localhost, TCP/IP will be used.

The error I am getting is simply "server connect failed." I am getting the same after I removed localhost from hostname.

How does TMysql57Connection know how to connect to the server if there is no hostname defined?

Re: [Lazarus] TMysql57Connection won't connect to localhost

Hello,

This means the mysql_real_connect() call failed. That means mysql itself
reports an error.

This means your connection parameters are somehow not correct:
one of hostname, port, username or password.

At this point the database name is not yet used. First a connection is made,
then the database is selected...

If you leave empty the hostname, it assumes localhost and will attempt a unix
socket connection first.

Do I understand it correctly that you are running the mysql in a bitnami
virtual machine ?

Is your lazarus also running in the virtual machine ? Or is lazarus running
on the host computer ?

Because if that is the case, you cannot use hostname localhost, but you must
use the IP address of the virtual machine.

If lazarus and mysql are running on the same (virtual) machine, then it is
something else.

For instance, what username did you use ? root@localhost or root ?
Hopefully the latter :).

Michael.

because if there's no host name it will try using a unix socket defined for the
server... that /is/ local but not localhost and not using tcp/ip networking
protocols... it is another way to connect to a server running on the same machine...

Seems you are missing one. I've resent it. Sent also to your private email address.
(At least I have seen it appearing on the mailing list)
