expect脚本之mysql_secure_installation (备注：初始化mariadb数据库)

一、初始化mariadb数据库脚本

1、安装expect软件

[root@mariadb script]# dnf install expect -y

2、编写脚本

[root@mariadb 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 

#给执行权限

chmod a+x mariadb_secure.exp 

#执行脚本

[root@mariadb script]# ./mariadb_secure.exp 
spawn mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      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)

Enter current password for root (enter for none):

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..

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? [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? [Y/n] Remove test database and access to it? [Y/n] Remove test database and access to it? [Y/n]  - Dropping test database...

Reloading the privilege tables will ensure that all changes made so far
will take effect immediately.

Reload privilege tables now? [Y/n] Reload privilege tables now? [Y/n] Y

Cleaning up...


All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!
