I should have added what I was using to do the transfer. I am using phpmyadmin to do a dump to a gzipped file and then I am importing.

RE: Moving MySQL data from Windows 4.0.12 to Linux 4.0.18
I had a situation you are seeing, what I ended up doing was create the db's in the new mysql server, setup replication, do LOAD DATA FROM MASTER let that run for a bit (while the first server is not in production of course) then after it synched up, shut down them both, removed the replication information and it started to work again. I may have copied the tables' files over, but I do not recall (~1.5years ago) HTH Thanks, James -Original Message- From: Lehman, Jason (Registrar's Office) [mailto:[EMAIL PROTECTED] Sent: Friday, August 27, 2004 12:32 PM To: [EMAIL PROTECTED] Cc: [EMAIL PROTECTED] Subject: RE: Moving MySQL data from Windows 4.0.12 to Linux 4.0.18 I should have added what I was using to do the transfer.

RE: Moving MySQL data to RAMDisk
MySQL is pretty good about following symlinks. Move /var/lib/mysql to /mnt/ramdisk/mysql and then symlink to it. # ln -s /mnt/ramdisk/mysql /var/lib/mysql Changing where everything resides in my.cnf should have been sufficient but the symlink way works great as well. And there should be no performance hit. I'm fairly certain I've read in the docs that it traverses a symlink to it's source directory and proceeds to access the files there instead of hitting the symlink every time. Also, take PHP out of the loop at first. Try accessing it via the command-line mysql client first and after you get that working, then introduce extra variables like apache/php into the mix. PS. Check permissions as well.. /mnt/ramdisk/mysql needs to very closely match the permissions of /var/lib/mysql (as well as owner/group). -Original Message- From: Creigh Shank [mailto:[EMAIL PROTECTED] Sent: Tuesday, August 19, 2003 8:35 AM To: MySQL Users Subject: Moving MySQL data to RAMDisk On moving my data files from /var/lib to /mnt/ramdisk I seem to be missing something.
