Update On: 23 Jul 2021Restore cpanel server from corrupted drive

Restore cpanel server from the fixed drive. If your server drive got fixed and need to restore data from it then you can use the following actions to restore data from a problematic drive.
Rsync stands for remote sync. rsync is used to perform the backup operation in UNIX / Linux. rsync utility is applied to synchronize the folders and directories. We can use this to restore the database from a corrupt drive.
Ask your DC to attach the corrupted drive as a secondary drive and mount the drive as an old drive 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 want to restore data to a remote server then copy files to the remote server. Enable SSH key authorized login without root password between both servers.
Go to old serve which is damaged 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  to 84.23.43.45 — /var/named/*.db
replace  to 84.23.43.45 — /usr/local/apache/conf/httpd.conf

Then updating scripts and restarting services…
