Four options that affect MySQL database security

The following articles mainly introduce four options that affect MySQL database security: secure, skip-grant-tables, and skip-name-resolve and skip-networking, the following is a description of the specific content of the article. I hope you will gain some benefits.

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 MySQL (the best combination with PHP) admin 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 MySQL (the best combination with PHP) d 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.

The above content is an introduction to MySQL database security. I hope you will find some gains.
