Description of problem:
while trying to fix mysqld fialed start
SELinux is preventing /usr/bin/bash from 'open' accesses on the file /var/log/mysqld.log.

*****  Plugin restorecon (99.5 confidence) suggests  *************************

If you want to fix the label. 
/var/log/mysqld.log default label should be mysqld_log_t.
Then you can run restorecon.
Do
# /sbin/restorecon -v /var/log/mysqld.log

*****  Plugin catchall (1.49 confidence) suggests  ***************************

If you believe that bash should be allowed open access on the mysqld.log file by default.
Then you should report this as a bug.
You can generate a local policy module to allow this access.
Do
allow this access for now by executing:
# grep mysqld_safe /var/log/audit/audit.log | audit2allow -M mypol
# semodule -i mypol.pp
