また、2021/05/26時点でのOracle Linux 7提供イメージでは、IPv6アドレスが有効化されていないため、インスタンス内のOS設定を変更する必要があり、DHCPv6アドレス取得ができなかったので、disable-ipv6.confと01_ipv6を作成した。 Oracle Linux 8だとIPv6有効化されていたがDHCPv6アドレス取得ができなかったので01_ipv6を作成したfirewalldにdhcpv6-clientの設定がされていないのでDHCPv6アドレス取得に失敗していたので設定を変更した。 Ubuntu 20.04ではIPv6有効化されておりDHCPv6アドレス取得はできたものの起動時に自動取得はしなかったので01_ipv6を作成しdhclient -6の方を有効にした。

どうやら「pcre2」と「socat」がOracle Autonomous Linuxでは提供されていないパッケージであるようだ。（標準のOralce Linux 7.8ではol7_latestレポジトリに含まれている)
先ほど指定したmariadbレポジトリはRedHat Enterprise Linux 7用だったので、CentOS7用(baseurl=http://yum.mariadb.org/10.5/centos7-amd64 )に変更しても状況は変わらず。
では、とバージョンを10.4に下げてみると成功。成功時のmariadb.repoは以下
