Description Eric Vantillard 2017-05-09 19:09:18 UTC
my koha-common.cnf is using this form:

[client]
host=db
user=root
password="move_rootpwd_to_dotenv"

this file is working has expected with mysql tools.

but koha-create parsing will not find the db host resulting in koha-conf.xml containing no values in hostname element.

as a result trying to connect to the web serveur will raise an error :

Software error:

DBIx::Class::Storage::DBI::catch {...} (): DBI Connection failed: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2) at /usr/share/perl5/DBIx/Class/Storage/DBI.pm line 1490. at /usr/share/koha/lib/Koha/Database.pm line 90

Comment 1 Eric Vantillard 2017-05-09 19:20:05 UTC
adding spaces around the equal sign will resolve the issue

the problem is in kohl-create function getmysqlhost()

https://github.com/Koha-Community/Koha/blob/master/debian/scripts/koha-create#L124

the awk search require spaces
Comment 2 Eric Vantillard 2017-05-09 20:04:10 UTC
maybe something like that

awk '
BEGIN {
	FS="="
}
$1 ~/\[/ {
	inclient=0
}
$1 ~/\[client\]/ {
	inclient=1
	next
}
inclient==1 && $1 ~/host/ {
	print $2
}
' /etc/mysql/koha-common.cnf

Bug 18564: MariaDB doesn't have a debian.cnf file

The koha-common.cnf file is a link to debian.cnf, which MariaDB
does not install. This just forces a 'localhost' return value.

Please move it to its own bug report.
