Restore cpanel server from corrupted drive

Restore cpanel server from corrupted drive. If your server drive got corrupted and need to restore data from it then you can use the following steps to restore data from problematic drive.

Rsync stands for remote sync. rsync is used to perform the backup operation in UNIX / Linux. rsync utility is used to synchronize the files and directories. We can use this to restore database from corrupt drive.

Ask your DC to attach corrupted drive as secondary drive and mount drive as olddrive folder

mount /dev/sdc /olddrive
We can start copying backup data from the old drive

If possible, do this process through SCREEN.

rsync -vrplogDtH /olddrive/usr/local/apache/conf /usr/local/apache
rsync -vrplogDtH /olddrive/var/named /var
rsync -vrplogDtH /olddrive/home/* /home
rsync -vrplogDtH /olddrive/usr/local/cpanel /usr/local
rsync -vrplogDtH /olddrive/var/lib/mysql /var/lib
rsync -vrplogDtH /olddrive/var/cpanel /var
rsync -vrplogDtH /olddrive/usr/share/ssl /usr/share
rsync -vrplogDtH /olddrive/var/ssl /var
rsync -vrplogDtH /olddrive/usr/local/cpanel/3rdparty/mailman /usr/local/cpanel/3rdparty
rsync -vrplogDtH /olddrive/var/log/bandwidth /var/log
rsync -vrplogDtH /olddrive/usr/local/frontpage /usr/local
rsync -vrplogDtH /olddrive/var/spool/cron /var/spool
rsync -vrplogDtH /olddrive/root/.my.cnf /root
rsync -vrplogDtH /olddrive/etc/httpd/conf/httpd.conf /etc/httpd/conf
Copy all old drive /etc folder configuration files.

cd /olddrive/etc

rsync -vrplogDtH secondarymx domainalias valiases vfilters exim* proftpd* pure-ftpd* passwd* group* *domain* *named* wwwacct.conf cpupdate.conf quota.conf shadow* *rndc* ips* ipaddrpool* ssl hosts /etc
Updating scripts and restarting services:

/scripts/upcp
/scripts/updatenow
/scripts/easyapache
/scripts/securetmp
/scripts/fixeverything
Restarting services as:

/scripts/restartsrv httpd
/scripts/restartsrv cpanel
/scripts/restartsrv mysql
/scripts/restartsrv named
/scripts/restartsrv exim
Done… Thats all!!!

If you need to restore data to remote server then copy files to remote server. Enable SSH key authorized login without root password between both servers.

Go to old serve which is corrupted drive.

cd /etc

rsync -vrplogDtH secondarymx domainalias valiases vfilters exim* proftpd* pure-ftpd* passwd* group* *domain* *named* wwwacct.conf cpupdate.conf quota.conf shadow* *rndc* ips* ipaddrpool* ssl hosts root@84.23.43.45:/etc
(84.23.43.45 is assumed as the IP of the new server to which we are moving the data.)

Now we need to transfer everything else.

rsync -vrplogDtH /usr/local/apache/conf root@84.23.43.45:/usr/local/apache
rsync -vrplogDtH /var/named root@84.23.43.45:/var
rsync -vrplogDtH /home/* root@84.23.43.45:/home
rsync -vrplogDtH /usr/local/cpanel root@84.23.43.45:/usr/local
rsync -vrplogDtH /var/lib/mysql root@84.23.43.45:/var/lib
rsync -vrplogDtH /var/cpanel root@84.23.43.45:/var
rsync -vrplogDtH /usr/share/ssl root@84.23.43.45:/usr/share
rsync -vrplogDtH /var/ssl root@84.23.43.45:/var
rsync -vrplogDtH /usr/local/cpanel/3rdparty/mailman root@84.23.43.45:/usr/local/cpanel/3rdparty
rsync -vrplogDtH /var/log/bandwidth root@84.23.43.45:/var/log
rsync -vrplogDtH /usr/local/frontpage root@84.23.43.45:/usr/local
rsync -vrplogDtH /var/spool/cron root@84.23.43.45:/var/spool
rsync -vrplogDtH /root/.my.cnf root@84.23.43.45:/root
rsync -vrplogDtH /etc/httpd/conf/httpd.conf root@84.23.43.45:/etc/httpd/conf
Dont forget to change remote server ip address in configuration.

replace <soureip> to 84.23.43.45 — /var/named/*.db
replace <soureip> to 84.23.43.45 — /usr/local/apache/conf/httpd.conf
Then updating scripts and restarting services…
