Apache and PHP5 seem to work fine. From terminal prompt as root getting error msgs.
ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
I have chown and chmod'd the directories for both var/run and tmp
but no files are being created.
Also ps -ln | grep mysql returns nothing
I've removed and reinstalled mysql-server.
bind is set to localhost
I read one post about inetd using port 3306 but that doesn't seem to be the problem.

The daemonl.log repeats these lines
Dec 29 19:17:16 ubuntu init: mysql post-start process (12652) terminated with status 1
Dec 29 19:17:16 ubuntu init: mysql main process (12730) terminated with status 1
Dec 29 19:17:16 ubuntu init: mysql main process ended, respawning

Kernal log keeps adding this line.
Dec 29 19:08:11 ubuntu kernel: [ 3833.393457] type=1505 audit(1293678491.371:142): operation="profile_replace" pid=11344 name="/usr/sbin/mysqld"

The error.log from/var/log/mysql shows this
101229 19:11:43 [Note] Plugin 'FEDERATED' is disabled.
/usr/sbin/mysqld: Can't find file: './mysql/plugin.frm' (errno: 13)

InnoDB: The error means mysqld does not have the access rights to

Can someone suggest debugging tricks to figure out this problem?

Your mysql may be trying to use a non-standard socket.

Maybe this will help.

Thanks for the suggestion but that use states
"i can access mysql with cocoamysql and through phpmyadmin no problem i have mysql-standard-4.1.12-"

I get the same error, no mysqld.sock when I access phpmyadmin.

I am running a dual boot, and the file system was ntfs (vista), an HP laptop.

I have used both apt-get install,remove, purge and the Synaptic Package Monitor.
Apache works
PHP info page works
MYSQL -V works
any mysql or mysqladmin command results in no mysqld.sock msg.

Try this as root: whereis mysql.sock.

Review everthing from this(tripple check):

https://help.ubuntu.com/community/Ap...&redirect=LAMP


hth and gl

root@ubuntu:/# pwd
/
root@ubuntu:/# whereis mysqld.sock
mysqld: /usr/sbin/mysqld /usr/share/man/man8/mysqld.8.gz
root@ubuntu:/#

I created a /var/run/mysqld/mysqld.sock and chmodded it 755

What logs should I be checking?

That is what I have been following, the packages all seemed to install ok -
I've made some scripts to display error msgs and file/pkg status

It looks to me (I'm not an expert but I have messed with MySQL quite a bit) that it can't find mysql.sock. In other words, it couldn't find a socket.

In a default install of MySQL, it would be in /var, I think in /var/mysql.

How are you starting mysql?

Hi all,

I just got the same problem, and I cannot find out a solution. What happened with this problem finally?
Thanks in advance,

Alfonso.

He did not know how to fire up MySQL which further research
on the database is a prerequisite.
sudo /etc/init.d/mysql restart

There are other commands for starting MySQL, BTW.
