1. Thêm MariaDB repo
Lưu ý: Không cần thực hiện trên CentOS 7. Phiên bản MariaDB trên CentOS 7 hiện nay là 5.5.37
## CentOS 6/5 MariaDB 5.5 ## wget -O /etc/yum.repos.d/MariaDB.repo http://mariadb.if-not-true-then-false.com/centos/$(rpm -E %centos)/$(uname -i)/5 ## CentOS 6/5 MariaDB 10.0 ## wget -O /etc/yum.repos.d/MariaDB.repo http://mariadb.if-not-true-then-false.com/centos/$(rpm -E %centos)/$(uname -i)/10
2. Cài đặt hoặc update MariaDB
## CentOS 7 ## yum install -y mariadb mariadb-server ## CentOS 6.5/5.10 ## yum install -y MariaDB MariaDB-server
3. Khởi động MariaDB và tự động chạy khi boot
## CentOS 7 ## systemctl start mariadb.service systemctl enable mariadb.service ## CentOS 6.5/5.10 ## service mysql start chkconfig --levels 235 mysql on
4. Cấu hình MariaDB
- Set (Change) root password
- Remove anonymous users
- Disallow root login remotely
- Remove test database and access to it
- Reload privilege tables
– Bắt đầu cài đặt
/usr/bin/mysql_secure_installation
Ngay bước đầu tiên bạn sẽ bị hỏi root password, do mới cài đặt nên tất nhiên chưa có password, nhấn Enter để tiếp tục.
– Output tương tự như sau:
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, 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!
