Description Dave Gordon 2010-06-04 16:31:58 UTC
Summary:

SELinux is preventing /bin/mkdir "write" access on /usr/local.

Detailed Description:

SELinux denied access requested by mkdir. It is not expected that this access is
required by mkdir 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.

Allowing Access:

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

Hash String generated from  catchall,mkdir,mysqld_safe_t,usr_t,dir,write
audit2allow suggests:

#============= mysqld_safe_t ==============
#!!!! The source type 'mysqld_safe_t' can write to a 'dir' of the following types:
# var_log_t, mysqld_var_run_t, mysqld_db_t, root_t

allow mysqld_safe_t usr_t:dir write;

Comment 1 Daniel Walsh 2010-06-04 21:03:50 UTC
This looks like local customization.  Any idea what directory mysql startup script is attempting to make?
