一、初始化mariadb資料庫腳本
1、安裝expect軟體
[[email protected] script]# dnf install expect -y
2、編寫腳本
[[email protected] script]# cat mariadb_secure.exp
#!/usr/bin/expect
set timeout 60
#set password [lindex $argv 0]
spawn mysql_secure_installation
expect {
"enter for none" { send "\r"; exp_continue}
"Y/n" { send "Y\r" ; exp_continue}
"password" { send "gxynova123\r"; exp_continue}
"Cleaning up" { send "\r"}
}
interact ' > mysql_secure_installation.exp
#給執行權限
chmod a+x mariadb_secure.exp
#執行腳本
[[email protected] script]# ./mariadb_secure.exp
spawn mysql_secure_installation

SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY!
In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, andhotdoor
you haven't set the root password yet, the password will be blank,
so you should just press enter here.hotdoor
hotdoor
Enter current password for root (enter for none):
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
hotdoor
Enter current password for root (enter for none):
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
hotdoor
Enter current password for root (enter for none):
ERROR 1045 (28000): Access denied for user 'root'@'localhost' (using password: YES)
hotdoor
Enter current password for root (enter for none):
OK, successfully used password, moving on...
Setting the root password ensures that nobody can log into the MariaDB
root user without the proper authorisation.

Reloading privilege tables..
... Success!
By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB without having to have a user account created for
them. This is intended only for testing, and to make the installation
go a bit smoother. You should remove them before moving into a
production environment.
Remove anonymous users? [Y/n] Y
... Success!
Normally, root should only be allowed to connect from 'localhost'. This
ensures that someone cannot guess at the root password from the network.
Disallow root login remotely? [Y/n] hotdoor
Y
... Success!
By default, MariaDB comes with a database named 'test' that anyone can
access. This is also intended only for testing, and should be removed
before moving into a production environment.
Remove test database and access to it? [Y/n] Remove test database and access to it? [Y/n] Remove test database and access to it? [Y/n] Remove test database and access to it?
