This article briefly introduces four options that affect mysqld security.

-- Secure

The IP number returned by the gethostbyname () system call is checked to ensure that they are resolved back to the original host name. This makes it harder for some outsiders to obtain access permissions by imitating other hosts. This option also adds some clever host name checks.

-- Skip-grant-tables

This option causes the server to not use the permission system at all. This gives everyone the right to fully access all databases! (By executing mysqladmin reload, you can tell a running server to start using the authorization table again .)

-- Skip-name-resolve

The host name is not resolved. The column values of all hosts in the authorization table must be IP numbers or localhosts.

-- Skip-networking

TCP/IP connections are not allowed on the network. All connections to mysqld must be made through Unix sockets. This option is not suitable for systems that use MIT-pthreads, because the MIT-pthreads package does not support Unix sockets.
