In this article we will demostrate myisamchk tool to repair some corrupted mysql databases as well mysqlcheck and repair table command.

Locate mysql databases:

cd /var/lib/mysql

myisamchk Utility (MyISAM Only)
Description: myisamchk can check and repair MyISAM tables

Running the repair command for all database tables:

myisamchk -q -r -f -s  *.MYI

Running the repair command for specific table:

myisamchk -q -r -f -s  table.MYI

Options used:

Change the collation used by the index.
-q, –quick        Faster repair by not modifying the data file. One can give a second ‘-q’ to force myisamchk to modify the original datafile in case of duplicate keys.
NOTE: Tables where the data file is corrupted can’t be fixed with this option.

-r, –recover      Can fix almost anything except unique keys that aren’t unique.

-f, –force         Overwrite old temporary files.

-s, –silent        Only print errors.  One can use two -s to make myisamchk very silent.

Other database repair tools:

REPAIR Table SQL Statement (MyISAM Only)

Usage:

mysql> REPAIR TABLE tablename;

In case the indexing file is missing or is corrupted u can use the USE_FRM option.

mysql> REPAIR TABLE tablename USE_FRM;

mysqlcheck Utility (MyISAM Only)

Old Server:
On the old server you will need first to create a backup of the site username using pkgacct tool. To do this you must have root privileges on the server.

cd /home
/scripts/pkgacct USERNAME

This will create a cpmove-USERNAME.tar.gz file which you will need to transfer to the new server to restore it.

To move the file to the new server can be done in various ways including FTP, SCP or just moving it to the public_html folder of your old server so you can download it from the new server directly.

In case you want to move the file to public_html you will need to do the following:

mv /home/cpmove-USERNAME.tar.gz /home/USERNAME/public_html
chmod 777 cpmove-USERNAME.tar.gz

New Server:

After you have transfered your cpmove-USERNAME.tar.gz file to the new server you have to restore the whole account back.

First lets assume that you have moved the backup file to public_html the steps to continue are:

cd /home
wget http://public_html_of_site.com/cpmove-USERNAME.tar.gz
/scripts/restorepkg USERNAME

When done just edit the DNS settings to reflect the new server.
