A long time ago my cpanel server was a mysql slave - I had not "deconfigured" this and tonight upon restart wiped out about 15 databases - mostly mine, plus a couple others. I restored all of them from hour old backups I just made. If I had not just done the backups, I'd lost a day or so..

Again, importance of backups and for "this is just a minor tweak" and "just a quick restart" .. yeah. Backup first.

So, summary was to disable being a slave server, then tar -xzf the backups, re-create the DB's, restore the DB's, restore permissions..

1. Disable the slave server - do this with mysql stopped.
   

   # mv master.info mcmaster.infooo

2. Restart the server and verify the slave status - nothing...

   root@vps2 [//home/unpack/cpmove-user/mysql]# mysql

   mysql> show slave status\G

   mysql> quit
   Bye

3. Unpack your cpmove backup - using /scripts/pkgacct to backup clients - makes for very easy restore..
4. cd to their unpack, for example /home/unpack/cpmove-user/mysql and I ran this command to blitz create all the user databases for the user:
   

   for sql in `ls user*`; do sql=`echo $sql | sed 's/\.sql//'`; echo "create database $sql; >> makedb.sql"; done; mysql < makedb.sql

5. With the DB's created, import the data:
   

   for sql in `ls user*`; do sqldb=`echo $sql | sed 's/\.sql//'`; mysql $sqldb < $sql; done

6. Now the DB's restored, restore the permissions from the file one directory up; mysql.sql
   

   # mysql < ../mysql.sql 

   This restored about 15 databases very quickly with original permissions, passwords and I was able to get right back to work.
