    Greeting mezz et al.

    My first thought was that perhaps the heat wave is getting to them over there. Check to be sure the DVD is not melting, reboot -- no better shut down and let it cool off for 1 hour -- take a cold shower ...

    Sorry you have to put up with my humor.

    Thy this method:
    Open one shell and type
    • su
      mysqld

    The shell will hang up but that is expected. Leave it open.
    Now open a new shell and type
    • mysql

    You should see
    • mysql>

    Best Wishes

    Thanks for humor, paradocs!!. Yes, it has been rather hot around here... But even your best wishes do not help! Get still the same message :
    '
    ERROR 2002: Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)
    '
    I think there is something rotten in the state of Knoppix DVD and MySQL ...

    Edwin, I agree with you : odder and odder. See what I get when I start MySQL on the 2003-07-26 CD
    '
    sudo less /ramdisk/var/log/mysql/mysql.err

    ect to server at 'localhost' failed
    error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysq

    Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock'
    exists!

    /usr/sbin/mysqld: ready for connections.
    Version: '4.0.13-log' socket: '/var/run/mysqld/mysqld.sock' port: 0
    '
    But for the rest everything goes fine ...

    Wishing you all the best as well!

    Regards,

    Georges.

    mzee,

    I only spotted this just now (must be the heat), so I give it another try.

    When attempting to copy the host.* files you used:

    Code:
    sudo cp -f /mnt/floppy/host.frm /KNOPPIX/var/lib/mysql/mysql
    cp: cannot remove `/KNOPPIX/var/lib/mysql/mysql/host.frm': Read-only file system
    You used '/KNOPPIX' as root for the destination where I used '/' This is a session from a CD boot:

    Code:
    knoppix@ttyp0[knoppix]$ sudo cp -f /mnt/floppy/host.frm /KNOPPIX/var/lib/mysql/mysql
    cp: cannot remove `/KNOPPIX/var/lib/mysql/mysql/host.frm': Read-only file system
    knoppix@ttyp0[knoppix]$ cat /KNOPPIX/var/lib/mysql/mysql/host.frm
    cat: /KNOPPIX/var/lib/mysql/mysql/host.frm: Permission denied
    knoppix@ttyp0[knoppix]$ sudo cp -f /mnt/floppy/host.frm /var/lib/mysql/mysql
    knoppix@ttyp0[knoppix]$  cat /var/lib/mysql/mysql/host.frm
    This is a test file
    This is not a MySql-table-description file
    knoppix@ttyp0[knoppix]$
    I don't know what this '/KNOPPIX' is (on the CD?) but we are clearly not supposed to mess with it. Using plain '/' as root works BTW. After my little sabotage-act MySql wouldn't start, complaining about incorrect information in host.frm.

    Regards,

    - - Edwin

    Thank you for keeping on!

    I followed your advice but with the same results :
    '

    ect to server at 'localhost' failed

    Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock'
    exists!

    ld.sock' (2)'
    Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock'
    exists!
    '
    Suggest we drop the subject. The Knoppix LinuxTag DVD is nice but MySQL on it doesn't work ....

    Happily MySQL works with the 20030606 and 20030726 Live CD's, although in a strange way : see my previous mail.

    Wish to thank you and the others for kind attention.

    Best Regards,

    Georges.

    ERROR MYSQL EN UBUNTU

    Also check if the deamon is running with 'ps -A | grep mysql'. If this returns some processes have a look at /var/log/mysql/mysql.err (as root). Do you have a mysql.pid file in /var/run/mysqld?

    mysql not running Konppix 4.0.1

    Hi,

    I just downloaded the 4.0.1 DVD version of knoppix and have the same problems to run mysql

    As there is no mysqld_safe file on the system, i tried to start it via "/etc/init.d/mysql start" as root. There must be a problem in this compilation

    Starting MySQL database server: mysqld...failed.
    Please take a look at the syslog.
    /usr/bin/mysqladmin: connect to server at 'localhost' failed
    error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)'
    Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock' exists!

    If I tried to start via mysqld_safe I get the following:
    root@3[www]# Starting mysqld daemon with databases from /var/lib/mysql
    mysqld_safe[14763]: started
    STOPPING server from pid file /var/run/mysqld/mysqld.pid
    mysqld_safe[14769]: ended


    Does anyone have a solution now for that?

    Thanks,
    Wolfixx

    You have to edit /etc/mysql/my.cnf

    Uncomment the line with: old_passwords = 1
