ServersMan@VPS CentOS6 MariaDBのInstall



まずは、 から CentOS→CentOS6 64bit→5.5と選んで

PLEASE REMEMBER TO SET A PASSWORD FOR THE MariaDB root USER ! To do so, start the server, then issue the following commands:

’/usr/bin/mysqladmin’ -u root password ‘new-password’ ‘/usr/bin/mysqladmin’ -u root -h dti-vps-srvXX password ‘new-password’

Alternatively you can run: ‘/usr/bin/mysql_secure_installation’

which will also give you the option of removing the test databases and anonymous user created by default. This is strongly recommended for production servers.

See the MariaDB Knowledgebase at or the MySQL manual for more instructions.

Please report any problems with the ‘/usr/bin/mysqlbug’ script!

Complete! [xxxxx@dti-vps-srvXX ~]$


つづいてhardening、、、。find_mysql_clientがcommand not foundだけど、無視していいので、無視する。

# mysql_secure_installationはsudoしなくて良い気がする。

[xxxxx@dti-vps-srvXX ~]$ sudo service mysql start
Starting MySQL.. SUCCESS!
[xxxxx@dti-vps-srvXX ~]$ sudo /usr/bin/mysql_secure_installation
/usr/bin/mysql_secure_installation: line 379: find_mysql_client: command not found


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, and you haven’t set the root password yet, the password will be blank, so you should just press enter here.

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.

Set root password? [Y/n] Y New password: Re-enter new password: Password updated successfully! 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] 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] Y - Dropping test database… … Success! - Removing privileges on test database… … Success!

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

Reload privilege tables now? [Y/n] Y … Success!

Cleaning up…

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

Thanks for using MariaDB! [xxxxx@dti-vps-srvXX ~]$
