I had an issue installing this via yum and I believe it to be a bug in the post-install scriptlet packaged in the MariaDB-Server rpm (both centos5 x86 and centos6 x86) .
If I should submit a bug report, let me know, but here is the gist of it:
Failing to first move my /etc/my.cnf somewhere else causes the post-install scriptlet in the RPM to construct a dangerous chown command.
In my case, the mysql_datadir=$basedir/$datadir
evaluates to: ""/""
That effectively ran the following command when installed:
chown -R mysql:mysql /
Needless to say, this caused a lot of problems, and all server permissions had to be corrected.
If this is a known issue, perhaps add in the instructions before installing via yum, to move the /etc/my.cnf out of the way, or consider a sanity check on that chown command? Perhaps an alternate method of determining the mysql datadir? Or maybe the script could simply temporarily move /etc/my.cnf to /etc/my.cnf.mariadb-save, before determining the mysql datadir?
Like I said, if I should submit a full bug report with all info and a way to reproduce, please let me know and I will.
Thanks, Kevin
