rubyのバージョンは2.5.1でしょうか？
古すぎてまもなくサポート終了なので、たとえば2.5.8などにアップデートされた方がよろしいかと。
(Rubyのサイトより)
WARNING: ruby-2.5.1 is nearing its end of life.
It only receives critical security updates, no bug fixes.
また、質問文ではgem mysql2のコンパイルに失敗しています。
Installing mysql2 0.4.10 with native extensions
Gem::Ext::BuildError: ERROR: Failed to build gem native extension.
下記メッセージを参考に、mysqlクライアントや開発用ライブラリなどのパッケージをインストールしてみてください。
パッケージ名はOS毎に違いますので、自分で調べてください。
ysql client is missing. You may need to 'apt-get install libmysqlclient-dev' or
'yum install mysql-devel', and try again.
