Description of problem:
SELinux is preventing (mysqld) from using the 'nnp_transition' accesses on a process.

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

If you believe that (mysqld) should be allowed nnp_transition access on processes labeled mysqld_t by default.
Then 应该将这个情况作为 bug 报告。
可以生成本地策略模块以允许此访问。
Do
allow this access for now by executing:
# ausearch -c '(mysqld)' --raw | audit2allow -M my-mysqld
# semodule -X 300 -i my-mysqld.pp
