SELinux is preventing /usr/bin/bash from using the dac_override capability.

                                                                              *****  Plugin dac_override (91.4 confidence) suggests   **********************

                                                                              If you want to help identify if domain needs this access or you have a file with the wrong permissions on your system
                                                                              Then turn on full auditing to get path information about the offending file and generate the error again.
                                                                              Do

                                                                              Turn on full auditing
                                                                              # auditctl -w /etc/shadow -p w
                                                                              Try to recreate AVC. Then execute
                                                                              # ausearch -m avc -ts recent
                                                                              If you see PATH record check ownership/permissions on file, and fix it,
                                                                              otherwise report as a bugzilla.

                                                                              *****  Plugin catchall (9.59 confidence) suggests   **************************

                                                                              If you believe that bash should have the dac_override capability 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:
                                                                              # ausearch -c 'mysqld_safe' --raw | audit2allow -M my-mysqldsafe
                                                                              # semodule -X 300 -i my-mysqldsafe.pp

이렇게 에러 떠 있다.

차례대로 

# auditctl -w /etc/shadow -p w

# ausearch -m avc -ts recent

# ausearch -c 'mysqld_safe' --raw | audit2allow -M my-mysqldsafe

# semodule -X 300 -i my-mysqldsafe.pp

입력 해주고

# systemctl restart mysql

해주면 정상 작동 된다.
