Then you should find out from the log file what it errors out on and fix that.


First of all this tutorial just removes and reinstalls software by reflex (common for users of tEh oTher OS) but more importantly it doesn't address the actual error. Like I wrote elsewhere on LQ some tutorials are not that good (outdated, incomplete, lacking knowledge, inefficient etc, etc) but this one is really bad.


No, the article said "rm -rf /var/lib/mysql". Alas it didn't tell you to make backups of your databases first and you didn't question the tutorials commands.


My ESP is at an all time low and so at least for me "it can't" is not a helpful indication of what happened. Next time try to be efficient and verbose listing complete commands and errors.


Depending on how log ago deletion happened and if you used the machine in the meantime (the lethal combo) you should attach large enough external storage or another partition and make a copy of the partition to a file on that disk as backup first (as in 'dd if=/dev/partition_name of=/mount_point/partition/name_of_file.dd'). If you only have space for recovered items or if you never separated /var from / then you just have to live with it. Boot a Live CD that contains Photorec, select the filter for only text and MySQL items and ensure you write recovered items to your attached external storage or a partition that does not hold /var.

Ouch, that was a really bad advice you got!
But now that it's done:
1) For any kind of undelete or rescue to succeed immediately unmount /var if it's on a separate partition or shutdown NOW!if it's on same as /.
This is because if /var is mounted & system is up things will be written to that partition and chance to succeed gets lower and lower.
Use a live-cd/dvd if necessary just don't mount the partition where /var is!
This is very very important so I stop here for now.
I'll write more, back soon!

Edit: Ok, unSpawn got in while I was writing, giving most of the solution I was ging to write.

@unSpawn

this the message when i install scalpel

@pingu: what I often do is use the Advanced reply box and then preview my post. That allows me to check what I post and if something was changed in or added to the thread I'm replying to.


Unless you mean something like ESX or equivalent you can configure a VMware guest to boot the ISO of a Live CD.
