Well i don't know if this is your case but i had a similar problem
installing mediawiki 1.25.3 AND my problem was with the server permissions.
The server didn't had the permission to access the db on the same machine.
Considering it has taken to me a long time to understand the problem i
advice you to run journalctl (or a similar command in your OS i don't know,
i use fedora. I had to fix a coupple of things but it was all written in
that file so i just add to copy and paste.. (well the command was actually:
# grep httpd /var/log/audit/audit.log | audit2allow
# semodule -i mypol.pp
so it was a problem with selinux).
Considering it took me 3 weeks to work this out i would be more than happy
to save you some time but maybe that's not the same problem..
my 2 cents

I had a database problem, and reinitialized and restored my database
from a recent logical (SQL source) backup. There were no changes to
any MediaWiki PHP files. The character set (UTF8) did not change.
Now, I get the infamous "[Sitename] has a problem… Can't contact the
database server: Permission denied (localhost)."
The host/database/user/password info in
LocalSettings.php has not
changed. I can use those same credentials to access the database
from various tools, such as mysql CLI client, phpMyAdmin, and Sequel
Pro. And yet, MediaWiki is still unwilling to connect. I even tried
tagging "?action=purge" onto the URL to rule out caching problems.
How exactly did you restore the backup? How did you re-create the users?
Did you "mysqladmin reload" after re-loading the "mysql" database?
Can you see the actual data after connecting with:
mysql -uuser -ppasswd mediawikidatabase
select * from revision limit 10;
I'm leaning toward a MySQL User permissions
problem, but I think I've
ruled that out by getting in using the same credentials with other
tools.
Any insight? Please show me something simple and stupid that I've been
overlooking!
Also you might need to login as the database supervisor (sometimes
called "root") and talk to the "mysql" database and examine entries
in
the "user" and "db" tables (and maybe "host").
Maybe that didn't get restored as it was before.
The best way to re-create the user needed is this:
GRANT INDEX, CREATE, SELECT, INSERT, UPDATE, DELETE, DROP, ALTER, LOCK
TABLES ON mediawikidatbase.* to 'wikiuser'@'localhost'
IDENTIFIED BY 'password';
Please keep in mind that 'wikiuser'@'%' and
'wikiuser'@'localhost' are
different users from the MySQL point of view, with their own passwords
and permissions.
