RHEL 8にNFSサーバをインストールしました。
今回はUbuntu 20にNFS Clientをインストールして共有フォルダをマウントしてみます。
環境
・Ubuntu 20.04.3 LTS
・Kernel 5.11.0-43-generic
- NFS Clientのインストール
- 共有フォルダの確認
- 共有フォルダのマウント
- アンマウント
- 起動時にマウント

showmountコマンドでNFS Serverが提供している共有フォルダを確認してみます。

rootlinks@Ubuntu20:~$ showmount -e 192.168.1.1 Export list for 192.168.1.1: /share 192.168.1.0/24 |
/mntにマウントしてみます。マウントできました。

rootlinks@Ubuntu20:~$ sudo mount -t nfs 192.168.1.1:/share /mnt rootlinks@Ubuntu20:~$ df -Th | grep nfs 192.168.1.1:/share nfs4 50G 6.9G 44G 14% /mnt |
マウントを解除します。

rootlinks@Ubuntu20:~$ sudo umount /mnt rootlinks@Ubuntu20:~$ df -Th | grep nfs |
/etc/fstabに記述してクライアント起動時に共有フォルダ/shareを/shareマウントします。

再起動後にログインすると/shareにマウントされていました。フォルダの作成、削除もできました。
