i usually disable awstats analog and webalizer on cPanel/WHM because there’s much better alternatives out there, like Google Analytics, however if you’re doing it on a server that has been running them for a while now, the cached data remains, so here’s a script to clean that up:
#!/bin/bash -x
for i in $(ls /var/cpanel/users)
do
cd /home/${i}/tmp && rm -rf analog awstats webalizer
done
Sometimes on cPanel/WHM the php user logs get large and/or might not get rotated properly. This script should take care of this
nano /root/logs.clear.sh
paste the contents below
chmod 700 logs.clear.sh
./root/logs.clear.sh
#!/bin/bash -x
for i in $(ls /var/cpanel/users)
do
cd /home/${i}/logs && find . -type f -name “*.php.error.log” -print0 | xargs -0 -I{} sh -c ‘echo “” > “{}”‘\;
done
Caught Error Cpanel::Exception::Backup::CorruptedBackupData : Ran some backups manually and stumbled into this error while checking the logs to see if the backups work fine (always check your logs, boys)

As it seems, this happens if you are running your backup volumes on a CIFS mount that is missing the “,user_xattr” parameter.
So what you need to do, is readjust your /etc/fstab as follows:
old:
//user.your-storagebox.de/backup /mnt/backups cifs iocharset=utf8,rw,credentials=/etc/backup-credentials.txt,uid=root,gid=root,file_mode=0660,dir_mode=0770 0 0
new:
//user.your-storagebox.de/backup /mnt/backups cifs iocharset=utf8,rw,credentials=/etc/backup-credentials.txt,uid=root,gid=root,file_mode=0660,dir_mode=0770,user_xattr 0 0
Then run “mount -o remount /mnt/backups” and in order to test is everything is working fine, do a “lsattr /mnt/backups” which should output the attributes of the mount. If it errors out, it means the mount doesn’t support extended attributes.
That should take care of things,
Cheers!
Apparently, the newest setup of cPanel servers comes in with MySQL8 by default. i have tried migrating a customer but there are some database incompatibilities, therefore we just put up another box with AlmaLinux 8 and here are the steps for performing a MySQL swap to MariaDB:
Now, this works on brand new servers, where maybe you forgot to setup MariaDB right in the beginning as per the cPanel tutorial here. If you have databases/users on the server and you still wish to downgrade, make sure to back them up beforehand, as we’re removing the SQL Server and the data.
That’s it! Enjoy!
