Check all commands again before executing them, don't trust random people like me without verification!** - -* sync your data, assuming it is in /home and /srv/(ftp/www) - -{{< highlight bash >}} -rsync --delete -av root@$SERV:/home/ /home -rsync --delete -av root@$SERV:/srv/ftp /srv -rsync --delete -av root@$SERV:/srv/www /srv -{{< / highlight >}} - -* transfer your databases - -{{< highlight bash >}} -ssh root@$SERV "mysqldump -u root -p$PASS --all-databases > /root/db.sql" -scp root@$SERV:/root/db.sql /root/ -mysql -u root -p$PASS < /root/db.sql -{{< / highlight >}} - -* sync configs (you might need more, this is just apache & vsftp) - -{{< highlight bash >}} -rsync --delete -av root@$SERV:/etc/httpd /etc -rsync --delete -av root@$SERV:/etc/letsencrypt /etc -rsync --delete -av root@$SERV:/etc/vsftpd /etc -{{< / highlight >}} - -* get crontabs over for later re-use, store them in the root home - -{{< highlight bash >}} -rsync --delete -av root@$SERV:/var/spool/cron /root -{{< / highlight >}} - -Now all things should be there and after some service restarts e.g. [WordPress](https://wordpress.org/) powered pages should be up-and-running again. - -I hope this short how-to helps others and allows me to avoid searching stuff in the future once again from scratch. |
