This article mainly introduces the four options that affect mysqld security in MySQL. I saw the related options that affect mysqld security in MySQL on a website a few days ago, but they are not comprehensive, so we will share this article with you today, and hope you will get some benefits.
This article briefly introduces four options that affect the security of MySQL (the best combination with PHP) d.
Four options that affect mysqld security in MySQL: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, which affects mysqld security in MySQL
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, which affects mysqld security in MySQL
The host name is not resolved. The column values of all hosts in the authorization table must be IP numbers or localhosts.
Skip-networking, which affects mysqld security in MySQL
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 describes the four options that affect MySQL's mysqld security. I hope it will help you in this regard.
