試したこと
いくつか調べましたが以下のようなコマンドを打ちましたが解決しませんでした。
sudo yum install php-mbstring
補足情報（FW/ツールのバージョンなど）
PHPの問題だと思いますので、インストールされているPHPのversionも載せます。

エラーに書いてある通りですが
the requested PHP extension dom is missing from your system.
php extensionのdomがあなたのシステムから見つかりません。
つまり、足りていないのはmbstringではなくdomです。
domは php-xmlをインストールすれば入ります
