1. Install the plug-ins necessary to prevent centos7 default nfs service does not start

    yum -y install nfs-utils rpcbind

    service rpcbind start

    service nfs start

[root@master nfs]# ps -ef|grep nfs
root      5598     2  0 10:08 ?        00:00:00 [nfsd4_callbacks]
root      5604     2  0 10:08 ?        00:00:00 [nfsd]
root      5605     2  0 10:08 ?        00:00:00 [nfsd]
root      5606     2  0 10:08 ?        00:00:00 [nfsd]
root      5607     2  0 10:08 ?        00:00:00 [nfsd]

root      5610     2  0 10:08 ?        00:00:00 [nfsd]
root      5611     2  0 10:08 ?        00:00:00 [nfsd]
root      5766     2  0 10:09 ?        00:00:00 [nfsv4.1-svc]
root      7703 14805  0 10:15 pts/1    00:00:00 grep --color=auto nfs
root     26932     2  0 09:36 ?        00:00:00 [nfsiod]
root     26942     2  0 09:36 ?        00:00:00 [nfsv4.0-svc]

2. Set up a shared directory password verification to remove insecure

    vim /etc/exports

  Add the line

   /mnt/nfs/ *(insecure,rw,async,no_root_squash)

3. Restart the direct use mount command

  Create a directory

  mkdir / mnt / nfs

  sudo mount -t nfs 172.19.68.9:/mnt/nfs/ /mnt/nfs
