Hi all,
one of my "lingering issues" since I am back working in Linuxland
(especially CentOS):
I have the "habit" to have dedicated virtual disks (or similar) for data,
e.g. /var/lib/mysql (so I can snapshot them separately, clone and move
between VMs etc.)
But that makes SELinux unhappy. I was surprised, actually..
What do I have to add to the SELinux contexts to allow this to happen?
Regards
Peter

Before moving the data do an ls -aliZ /var/lib/ | grep -i mysql and use
the same security context accordingly once you move it to new
server/partition using "chcon"

Hi Majoosh,
thanks.
But I created an empty /var/lib/mysql partition before I wanted to install
mysql.
With the result that I could not install mysql successfully.
I probably have to re-enact it again because I do not remember whether the
install failed or the server did not start up.
It was the later, I think.
Regards
Peter

restorecon -R -v /var/lib/mysql

Having just /var/lib/mysql on a separate partition probably isn't the best
idea, you can't make a backup of that without backing up the logs too so it's
best to put them on the same filesystem. For a system that has mysqld as an
important part of the system functionality (which is most systems that have
MySQL running) I create a subvol or filesystem named /mysql.
semanage fcontext -a -t mysqld_db_t "/mysql(/.*)?"
restorecon -R -v /mysql
The above commands will give you the correct labeling for /mysql.
