Restore the Cpanel server from the damaged drive. If your server drive got damaged and want to recover data from it then you can use the following steps to recover data from the problematic drive.
Rsync holds for remote sync. rsync is applied to perform the backup service in UNIX / Linux. rsync benefit is applied to synchronize the reports and files. We can use this to recover the database from a corrupt drive.
Ask your DC to connect corrupted drive as secondary drive and mount drive as olddrive folder
mount /dev/sdc /olddrive
We can light the following backup data from the old drive
If possible, do this method through SCREEN.
rsync -vrplogDtH /olddrive/usr/local/apache/conf /usr/local/apachersync -vrplogDtH /olddrive/var/named /varrsync -vrplogDtH /olddrive/home/* /homersync -vrplogDtH /olddrive/usr/local/cpanel /usr/localrsync -vrplogDtH /olddrive/var/lib/mysql /var/librsync -vrplogDtH /olddrive/var/cpanel /varrsync -vrplogDtH /olddrive/usr/share/ssl /usr/sharersync -vrplogDtH /olddrive/var/ssl /varrsync -vrplogDtH /olddrive/usr/local/cpanel/3rdparty/mailman /usr/local/cpanel/3rdpartyrsync -vrplogDtH /olddrive/var/log/bandwidth /var/logrsync -vrplogDtH /olddrive/usr/local/frontpage /usr/localrsync -vrplogDtH /olddrive/var/spool/cron /var/spoolrsync -vrplogDtH /olddrive/root/.my.cnf /rootrsync -vrplogDtH /olddrive/etc/httpd/conf/httpd.conf /etc/httpd/conf
Copy all old drive /etc folder configuration files.
cd /olddrive/etcrsync -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:
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 /etcrsync -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 firstname.lastname@example.org:/etc
(22.214.171.124 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 email@example.com:/usr/local/apachersync -vrplogDtH /var/named firstname.lastname@example.org:/varrsync -vrplogDtH /home/* email@example.com:/homersync -vrplogDtH /usr/local/cpanel firstname.lastname@example.org:/usr/localrsync -vrplogDtH /var/lib/mysql email@example.com:/var/librsync -vrplogDtH /var/cpanel firstname.lastname@example.org:/varrsync -vrplogDtH /usr/share/ssl email@example.com:/usr/sharersync -vrplogDtH /var/ssl firstname.lastname@example.org:/varrsync -vrplogDtH /usr/local/cpanel/3rdparty/mailman email@example.com:/usr/local/cpanel/3rdpartyrsync -vrplogDtH /var/log/bandwidth firstname.lastname@example.org:/var/logrsync -vrplogDtH /usr/local/frontpage email@example.com:/usr/localrsync -vrplogDtH /var/spool/cron firstname.lastname@example.org:/var/spoolrsync -vrplogDtH /root/.my.cnf email@example.com:/rootrsync -vrplogDtH /etc/httpd/conf/httpd.conf firstname.lastname@example.org:/etc/httpd/conf
Dont forget to change remote server ip address in configuration.
replace to 126.96.36.199 — /var/named/*.dbreplace to 188.8.131.52 — /usr/local/apache/conf/httpd.conf
Then updating scripts and restarting services…
