これは MySQL Advent Calendar 2020 17 日目のエントリです（後から穴埋め）。

AWS では今年、EC2・RDS に 64-bit Arm ベースの Graviton2 プロセッサを採用したインスタンスを立てられるようになりましたので、EC2 の r6g.large インスタンス（2vCPU・メモリ 16GiB）に MySQL Server 8.0.22 をインストールしてみました。

※本当にインストールしただけです（続きは後日）。

EC2 インスタンス起動

まずは 64-bit Arm 向けの CentOS 8.3（あえて Stream ではない）を選んで、

r6g.large インスタンスを選択して…

ストレージは gp3 を選んでインスタンスを立ててみました。

MySQL Community Server 8.0.22 インストール

x86_64 系プロセッサを使う場合とほぼ同様に MySQL Community Server 8.0.22 をインストールしていきます。

※適宜、言語・ロケールなどの設定を行ってください（ここでは省略）。

まずはwgetを入れる

$ sudo dnf install wget

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? (Press y|Y for Yes, any other key for No) : 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? (Press y|Y for Yes, any other key for No) : 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? (Press y|Y for Yes, any other key for No) : y

Success.

 - Removing privileges on test database...
Success.

Reloading the privilege tables will ensure that all changes
