Centos 7でNFSを起動できません。メソッド呼び出しを実行できません。そのファイルやディレクトリはありません。

CentOS7でNFSサーバーを起動できません。

ダウンロードしたパッケージ：

yum -y install nfs-utils
yum -y install nfs-utils-lib

サービスの有効化/開始

systemctl enable/start rpcbind
systemctl enable/start nfs-server
systemctl enable/start nfs-lock
systemctl enable/start nfs-idmap

その結果は次のとおりです。

systemctl enable nfs-lock
Failed to issue method call: No such file or directory
systemctl enable nfs-idmap
Failed to issue method call: No such file or directory

共有を作成する：

mkdir -p /test
chmod 777 /test

輸出罰金：

exportfs
/test           clientip/24

ただし、systemctlrestartを実行すると、nfs-server依存関係エラーが原因で失敗し、次のようにjournalctlなります。

[user@server /]# journalctl -xn | grep failed
-- Subject: Unit proc-fs-nfsd.mount has failed
-- Unit proc-fs-nfsd.mount has failed.
-- The result is failed.
Jun 23 17:06:41 server systemd[1]: Dependency failed for NFS server and services.
-- Subject: Unit nfs-server.service has failed
-- Unit nfs-server.service has failed.
Jun 23 17:06:41 server systemd[1]: Dependency failed for NFS Mount Daemon.
-- Subject: Unit nfs-mountd.service has failed
-- Unit nfs-mountd.service has failed.
Jun 23 17:06:41 open

そして、systemctlリスト単位の状態にも失敗が表示されます。
