NFS服务端min1

安装nfs

[root@nfs_server ~]# yum -y install nfs-utils rpcbind

设置开机启动nfs相关服务

[root@nfs_server ~]# systemctl enable rpcbind
[root@nfs_server ~]# systemctl enable nfs-server
Created symlink from /etc/systemd/system/multi-user.target.wants/nfs-server.service to /usr/lib/systemd/system/nfs-server.service.
[root@nfs_server ~]# systemctl enable nfs-lock
[root@nfs_server ~]# systemctl enable nfs-idmap

启动nfs service

[root@nfs_server ~]# systemctl start rpcbind
[root@nfs_server ~]# systemctl start nfs-server
[root@nfs_server ~]# systemctl start nfs-lock
[root@nfs_server ~]# systemctl start nfs-idmap

创建共享目录，注意给777权限

[root@nfs_server ~]# mkdir -p /mynfs/mpi_share -p #级联创建
[root@nfs_server ~]# chmod -R 777 /mynfs/mpi_share 更改share文件夹及其子文件夹权限为777

/etc/exports

/mynfs/mpi_share min1(rw,sync,no_root_squash)
/mynfs/mpi_share min2(rw,sync,no_root_squash)

[root@nfs_server ~]# exportfs -a          使exports的修改生效

检查共享目录是否设置正确

[root@nfs_server /]# showmount -e
Export list for nfs_server:
/application/share 192.168.0.*

调整防火墙配置

[root@nfs_server ~]# firewall-cmd --add-service=nfs --permanent --zone=public
success
[root@nfs_server ~]# firewall-cmd --add-service=mountd --permanent --zone=public
success
[root@nfs_server ~]# firewall-cmd --add-service=rpc-bind --permanent --zone=public
success
[root@nfs_server ~]# firewall-cmd --reload   重新载入配置，使其生效
success

NFS客户端min2

安装nfs

[root@nfs_client ~]# yum -y install nfs-utils

检查共享目录是否设置正确

[root@nfs_client ~]# showmount -e min1   #min1是服务端
Export list for 192.168.0.240:
/application/share 192.168.0.*

创建对应的共享目录

[root@nfs_client ~]# mkdir -p /mynfs/mpi_share  #随意，没必非要和min1一致

挂载目录

临时挂载共享目录

注意，每次重启client时都需要执以下命令

[root@nfs_client ~]# mount -t nfs min1:/mynfs/mpi_share /mynfs/mpi_share

注意，此时是暂时型的nfs,重启后失效。

永久挂载

以下均是client端操作

min2上

vim /etc/rc.d/rc.local

添加
mount -t nfs min1:/mynfs/mpi_share /mynfs/mpi_share

vim /etc/fstab

min1:/mynfs/mpi_share /mynfs/mpi_share nfs rw 0 0

---

测试

无论是client还是server的 /mynfs/mpi_share目录下创建文件即可
