mysql.sock is required for mysqld processes to operate. For example, if your mysql.sock file exists in /tmp and you decide to delete all the 'temp files' you will have a problem with mysql Smilie

You should make sure you know which directory that the mysql.sock file is created and make sure the mysqld processes have permission to write to that directory... and make sure that prior mysql.sock files are either deleted or have correct permissions so when another process is started it can overwrite this file.

For example:

Quote:

server# cd /tmp
server# ll *sock*
srwxrwxrwx 1 root root 0 Aug 10 00:14 mysql.sock=
server#

Notice that the mysql.sock file is in /tmp and the permission are root.root because mysql is running as root.root. If you are not running mysql as root, then you could have problems writing if another mysql.sock file exists, etc.

My advise is to find out where your system is writing this file, shutdown mysql, delete all the old mysql.sock files, check permissions and restart.

DBIx::SearchBuilder::Handle::mysql(3pm) 		User Contributed Perl Documentation		   DBIx::SearchBuilder::Handle::mysql(3pm)

NAME

	 DBIx::SearchBuilder::Handle::mysql - A mysql specific Handle object

SYNOPSIS

DESCRIPTION

       This module provides a subclass of DBIx::SearchBuilder::Handle that compensates for some of the idiosyncrasies of MySQL.

METHODS

   Insert
       Takes a table name as the first argument and assumes that the rest of the arguments are an array of key-value pairs to be inserted.

       If the insert succeeds, returns the id of the insert, otherwise, returns a Class::ReturnValue object with the error reported.

   SimpleUpdateFromSelect
       Customization of "SimpleUpdateFromSelect" in DBIx::SearchBuilder::Handle.  Mysql doesn't support update with subqueries when those fetch
       data from the table that is updated.

   DatabaseVersion
       Returns the mysql version, trimming off any -foo identifier

   CaseSensitive
       Returns undef, since mysql's searches are not case sensitive by default

   SimpleDateTimeFunctions
       Returns hash reference with specific date time functions of this database for "DateTimeFunction" in DBIx::SearchBuilder::Handle.

   ConvertTimezoneFunction
       Custom implementation of "ConvertTimezoneFunction" in DBIx::SearchBuilder::Handle.

       Use the following query to get list of timezones:

	   SELECT Name FROM mysql.time_zone_name;

       Read docs about keeping timezone data up to date:
