Description František Zatloukal 2017-09-05 11:24:50 UTC
Description of problem:
Starting MariaDB failed because of SELinux preventing it from writing to log file.
SELinux is preventing mysqld from 'map' accesses on the file /var/lib/mysql/tc.log.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that mysqld should be allowed map access on the tc.log file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
allow this access for now by executing:
# ausearch -c 'mysqld' --raw | audit2allow -M my-mysqld
# semodule -X 300 -i my-mysqld.pp
