Description Augusto Cuellar Galmich 2009-12-25 18:42:16 UTC
Resúmen:

SELinux is preventing /bin/rm "unlink" access on /var/run/mysqld/mysqld.pid.

Descripción Detallada:

SELinux denied access requested by rm. It is not expected that this access is
required by rm and this access may signal an intrusion attempt. It is also
possible that the specific version or configuration of the application is
causing it to require additional access.

Permitiendo Acceso:

You can generate a local policy module to allow this access - see FAQ
(http://fedora.redhat.com/docs/selinux-faq-fc5/#id2961385) Please file a bug
report.

You can add these rules for now using

# grep avc /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
