MySQL

[paradocs]

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>

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

But for the rest everything goes fine ...

Wishing you all the best as well!

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:

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:

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.

Thank you for keeping on!

I followed your advice but with the same results :
'
030808 20:54:05 Error at /KNOPPIX/etc/init.d/mysql\n^G/usr/bin/mysqladmin: conn
ect to server at 'localhost' failed

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.

I am not familiair with the DVD version, but does it start the mysql daemon automaticly at boot? Or do you start it manually? If the first go through the boot messages with 'dmesg' in a console. Look for error messages. If the last, what does it say after you start it?

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?

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

Hi Impf,

Thank you very much; now it works
