如何开通NFS服务并在其他服务器中挂载-马春杰杰

1、宿主机开通NFS服务

直接运行下面的命令即可，注意修改其中的路径为自己的。

sudo apt install -y nfs-kernel-server
mkdir -p /raid/NFSshare/datasets2
chmod 777 /raid/NFSshare/datasets2
echo '/raid/NFSshare/datasets2 *(rw,sync,root_squash,no_subtree_check,secure)' | sudo tee -a /etc/exports
sudo exportfs -ra
sudo systemctl enable --now nfs-server

sudo apt install -y nfs-kernel-server

mkdir -p /raid/NFSshare/datasets2

chmod 777 /raid/NFSshare/datasets2

echo '/raid/NFSshare/datasets2 *(rw,sync,root_squash,no_subtree_check,secure)' | sudo tee -a /etc/exports

sudo exportfs -ra

sudo systemctl enable --now nfs-server

2、容器内挂载

依次运行下面的命令，注意修改IP地址和路径：

sudo apt install -y nfs-common
sudo mkdir -p /NFSshare/datasets
sudo mkdir -p /NFSshare/datasets2
# 只做测试：sudo mount -t nfs -o vers=4.2,nconnect=4,rsize=1048576,wsize=1048576,noatime,hard 172.16.150.201:/raid/NFSshare/datasets2 /NFSshare/datasets2
vi /etc/fstab
172.16.150.201:/raid/NFSshare/datasets2  /NFSshare/datasets2  nfs  vers=4.2,nconnect=4,rsize=1048576,wsize=1048576,noatime,hard,_netdev,x-systemd.requires=network-online.target,x-systemd.after=network-online.target,nofail  0  0
sudo systemctl daemon-reload
sudo systemctl enable --now systemd-networkd-wait-online.service 
sudo systemctl enable --now NetworkManager-wait-online.service  # 这一步如果报错没事
sudo mount -a
findmnt /NFSshare/datasets2

sudo apt install -y nfs-common

sudo mkdir -p /NFSshare/datasets

sudo mkdir -p /NFSshare/datasets2

# 只做测试：sudo mount -t nfs -o vers=4.2,nconnect=4,rsize=1048576,wsize=1048576,noatime,hard 172.16.150.201:/raid/NFSshare/datasets2 /NFSshare/datasets2

vi /etc/fstab

172.16.150.201:/raid/NFSshare/datasets2 /NFSshare/datasets2 nfs vers=4.2,nconnect=4,rsize=1048576,wsize=1048576,noatime,hard,_netdev,x-systemd.requires=network-online.target,x-systemd.after=network-online.target,nofail 0 0

sudo systemctl daemon-reload

sudo systemctl enable --now systemd-networkd-wait-online.service

sudo systemctl enable --now NetworkManager-wait-online.service # 这一步如果报错没事

sudo mount -a

findmnt /NFSshare/datasets2

如果成功，会提示：

root@autodl2:~# findmnt /NFSshare/datasets2
