Debian 5.0 -ISPConfig 3 install - Unable to connect to mysql server
I have followed all the steps given in the manual and so far it was going well till i started installing ISPConfig 3
I started installing ISPConfig 3 with the SVN, selected the language and used the default (which are appropriate) values for the questions
when it try to connect to MySQL server or the database it asked me the questions to enter hostnamme, username, password, database to crease, charset.

Then it gave me an error saying:
"Unable to connect to mysql server Can't connect to local MySQL server through socket 'var/run/mysqld/mysqld.sock' (2)

Any idea what i should do?

This means that your mysql server is not correctly installed or running. Please redoo the mysql installation steps from the ispconfig 3 manual and make sure that you really started the mysql server.

i did install the mysql server and other things in step 1. howeever i re-did it right now and it gave me a sessage saying everything is uptodate.
when i type the command "/etc/init.d/mysql restart" it displayed the following

Stopping MySQL database server: mysqld.
Starting MySQL database server: mysqld.
Checking for corrupt, not cleanly closed and upgrade needing tables..

and for "/etc/init.d/mysql status" it gives
Server Version 5.0.51a-24
Protocol version 10
Connection Localhost via UNIX socket
UNIX socket /var/run/mysqld/mysqld.sock
uptime: 2 mins 2 sec

Threads: 1 Questions: 78 slow queries: 0 Opens: 23 Flush Tables: 1 Open tables: 17 Queries per second avg: 0.639

Any thing that you can think of???

Well it worked for one reason or the other when i asked for the status and re ran the installation process with the root password.

Thank you for your help.

Can't connect to mySQL to /var/lib/mySQL/mySQL.sock
I am using Centos 5.3 and I had the same problem, I solved this way...

removed myDNS
using phpmyadmin removed all ispconfig or mydns DBs and users


reinstall myDNS
reinstall ISPCONFIG3

this steps should work on any linux distro.

I get the
Unable to connect to mysql server
During a Wheezy ispconfig3 multiserver install.

The Mysql server installation accepts special characters and passwords over 50 characters in length where ISSpconfig does not and may simply tuncate them.

I have kept my passwords below 49 but I ended up with the same error when attempting to install the secondary DNS server.

What are the ispconfig pw parameters?
Is there a limit on the total number of characters in a multi server environment?

The next server installed proverly so it appears that I improperly installed the DB credentials on one of the servers andd all is good if you keep passwords under 49
