そういえば、まだ、CentOS 7をあまりいじっていなかったので、とりあえず手始めにMySQLをインストールしてみました。
環境はAmazon EC2です。
AMIは、CentOS 7 (x86_64) with Updates HVMです。
AMI ID: CentOS 7 x86_64 (2014_09_29) EBS HVM-b7ee8a69-ee97-4a49-9e68-afaee216db2e-ami-d2a117ba.2 (ami-89634988)
Instance Type: c3.xlarge
EBS: General Purpose (SSD)
* こちらのURLから最新のMySQLのyumレポジトリを探します。
http://dev.mysql.com/downloads/repo/yum/
Red Hat Enterprise Linux 7のDownloadリンクをクリック -> "No thanks, just start my download."のURLが最新です。
* MySQLのレポジトリをインストール。el7を選びます。
# rpm -i http://dev.mysql.com/get/mysql-community-release-el7-5.noarch.rpm
* MySQLをインストール。
# yum install mysql-community-server mysql-community-devel
* MySQLサービスをスタート。/etc/init.d/mysqldじゃあなくなっているので注意です。
# service mysqld start
* MySQLのステータスをチェック。色々出てくるようになりました。

※ パスワードは便宜設定してください
# mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MySQL SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MySQL to secure it, we'll need the current password for the root user. If you've just installed MySQL, 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 MySQL root user without the proper authorisation.< Set root password? [Y/n] Y New password:AAAAAA Re-enter new password:AAAAAA Password updated successfully! Reloading privilege tables.. ... Success! By default, a MySQL installation has an anonymous user, allowing anyone to log into MySQL 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, MySQL 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... ERROR 1008 (HY000) at line 1: Can't drop database 'test'; database doesn't exist ... Failed! Not critical, keep moving... - 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! All done! If you've completed all of the above steps, your MySQL installation should now be secure. Thanks for using MySQL! Cleaning up...
