[solved] mySQL Socket problem

[quwax]

Hello,
this didn't happen with php 5.x, but after upgarding to php7.2 I have this wired problem:
the mysql socket is set correctly in the php.ini file (as before):
pdo_mysql.default_socket = /private/var/mysql/mysql.sock
mysql.default_socket = /private/var/mysql/mysql.sock
mysqli.default_socket = /private/var/mysql/mysql.sock
and I can access the installer, but I neither can login to the mailserver nor can I send.
With IMAP I get a connection refused error, which doesn't reflect in the server logs
with smtp I get a socket error.
My temporary solution is to create a symbolic link in the temp folder:
ln -s /var/mysql/mysql.sock mysql.sock
then everything works as expected. Of course after every restart the symbolic link is gone ;-)
Wordpress has no issues, so it must be an imap/smtp thing.
Where can I look for the wrong socket path?
thanks

Found the culprit, the pdo and mysqli socket was also set in the php.ini file with an empty path … setting the correct path fixed it :-)

To explain, I'm using the entropy php7.2 installation on MacOS 10.11
The manual said the mysql path is set in 99-liip-developer.ini, but only for mysql and not the other ones, which are set in the php.ini file :-D
