Is it my opinion, or Unix & Linux systems dislike me???? Smilie

New problem

I want to mysqldump a database from a Red Hat 9 mysql server,
to a Solaris 7 mysql server.

the problem is :

Mysql server in Red Hat 9 is up and running. (Its the production server).
I'm trying to mysqldump a database, and provides me the below error.

/usr/local/mysql/bin/mysqldump: Got error: 2002: Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) when trying to connect

Remember, this server is up and running.

I'm searching everywhere for mysql.sock, or *.sock, and I can't find anything.
there is no mysql.sock file in the system (hidden or not).
There is no .sock file in the system.

mysqld.log it exists but is empty, so I can't get any information from there.

Now,

in Solaris 7, mysql.sock exists, in a proper location '/tmp/mysql.sock',
but its empty.
Mysql server, in Solaris 7, its also up and running.

My obvious question is , how to make mysqldump work without any mysql.sock file in the system????

But I want to add another question.
If I'll create, in Red Hat 9, a '/tmp/mysql.sock' file, empty of course, will it cause any damage to the mysql server, which is up and running????????

Thanks again.

I'll never give up, never give in Smilie

pmdamysql

PMDAMYSQL(1)						       Performance Co-Pilot						      PMDAMYSQL(1)

NAME

       pmdamysql - MySQL database PMDA

DESCRIPTION

       pmdamysql is a Performance Co-Pilot PMDA which extracts live performance data from a running MySQL database.

INSTALLATION

       pmdamysql uses a configuration file from (in this order):

       o   /etc/pcpdbi.conf

       o   $PCP_PMDAS_DIR/mysql/mysql.conf

       This file can contain overridden values (Perl code) for the settings listed at the start of pmdamysql.pl, namely:

       o   database name (see DBI(3) for details)

       o   database user name

       o   database pass word

       Once this is setup, you can access the names and values for the mysql performance metrics by doing the following as root:

	       # cd $PCP_PMDAS_DIR/mysql
	       # ./Install

       If you want to undo the installation, do the following as root:

	       # cd $PCP_PMDAS_DIR/mysql
	       # ./Remove

       pmdamysql is launched by pmcd(1) and should never be executed directly.	The Install and Remove scripts notify pmcd(1) when the agent is
       installed or removed.

Binary Status values in text
       Some of the status values are in the form of YES/NO or ON/OFF.

       Since these cannot be intepreted by tools like PMIE, they have been duplicated with a _num extension and the values of 1 (YES/ON) or 0
       (NO/OFF).

   Eg:
       o   mysql.slave_status.slave_io_running

       o   mysql.slave_status.slave_io_running_num
