Hello Guys,
I am completly pulling my hair out at the moment trying to recover my wiki database, here is what happend.
I was installing Beryl 1.4 and made the mistake of doing a emerge -uDav beryl
this command upgraded my mysql database from a version to 5.0.30.
I have tried to copy copy over the data dir from my old db location to the new location (since it won't start mysql if i specify a diff db location other than the default)
It tells me when i try and run the following that i am running the wrong version of the db for the database
| Code: |
mysql> select * from user;
ERROR 1033 (HY000): Table './wikidb/user' was created with a different version of MySQL and cannot be read
|
I have no clue what version of mysql was installed to be honest as this was done a while ago.
I think it could have been 4x something but not sure.
I have masked out the following versions of mysql
| Code: |
>=dev-db/mysql-5.0.26-r1
>=dev-db/mysql-5.0.30
|
and have installed version
| Code: |
* dev-db/mysql
Latest version available: 4.1.22
Latest version installed: 4.1.22
Size of files: 17,393 kB
Homepage: http://www.mysql.com/
Description: A fast, multi-threaded, multi-user SQL database server.
License: GPL-2
|
I have cd'd into the /var/lib/mysql/wikidb dir and run
which retuens the following
| Code: |
user.frm: MySQL table definition file Version 10
|
Can anyone tell from this version what mysql version I had installed? or of any tools that would allow me to upgrade these files to work with mysql 5.0.30?
i am still getting the error about the wrong version of the database.
I am pulling my hair out at the moment, i have some development work to complete and i need to be able to copy the live dbs to my machine to work at home
can anyone suggest anything that i haven't already tried. |

| You might find your previous version number in /var/log/emerge.log. Everything you emerge, gets logged. After downgrading you might try to upgrade by following the mysql upgrade guide in the gentoo docs. Do you know how to downgrade? |
