リポジトリの追加

リポジトリの追加前はこんなだったのが

$ yum list | grep mariadb

リポジトリを追加することで

$ curl -sS https://downloads.mariadb.com/MariaDB/mariadb_repo_setup | sudo bash
[sudo] user のパスワード:
[info] Repository file successfully written to /etc/yum.repos.d/mariadb.repo.
[info] Adding trusted package signing keys...
[info] Succeessfully added trusted package signing keys.

こうなる。

yum でインストール

$ sudo yum install MariaDB-server

簡単。依存関係で MariaDB-Client もインストールされるよう。

起動

$ sudo systemctl start mariadb

次回 OS 起動時に自動起動させる。

$ sudo systemctl enable mariadb

firewall の設定

firewall に拒否されていたので，設定変更。

$ sudo firewall-cmd --permanent --add-service=mysql
$ sudo systemctl restart firewalld
