Ensure `skip-grant-tables` Is Disabled

严重级别 1自动化tdsql

说明

When MySQL is started with --skip-grant-tables, the server does not load the privilege system, and any user can log in without authentication and perform arbitrary operations. Counts mysqld processes started with --skip-grant-tables and my.cnf files (/data/tdsql/mysqld/*/my.cnf, /etc/my.cnf) that enable it.
