NFS配置
一，配置nfs服务端
nfs服务端IP：192.168.1.10
1，安装nfs

2，配置nfs服务端
[root@localhost ~]# mkdir /nfs //创建共享目录 [root@localhost nfs]# vim /etc/exports /nfs 192.168.1.* (rw,sync,root_squash) //分别是共享目录、允许访问的客户端、权限（读写、同步内存和硬盘数据、映射root用户为匿名用户）
3，启动nfs服务端
[root@localhost nfs]# systemctl is-enabled nfs-server //查看"nfs-server"是否开机启动 disabled [root@localhost nfs]# systemctl enable nfs-server //将"nfs-server"加入开机启动 ln -s '/usr/lib/systemd/system/nfs-server.service' '/etc/systemd/system/nfs.target.wants/nfs-server.service'
[root@localhost nfs]# systemctl is-enabled rpcbind //查看"rpcbind"是否加入开机启动，"nfs-server"依赖于"rpcbind"
enabled
[root@localhost nfs]# systemctl restart rpcbind
[root@localhost ~]# showmount -e //查看是否共享成功
Export list for localhost.localdomain:
/nfs (everyone)
二，通过客户端验证
1，安装nfs-utils
[root@localhost ~]# yum -y install nfs-utils Loaded plugins: product-id, subscription-manager This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

2，启动"rpcbind"和"nfs-server"，并加入开机启动
3，挂载服务端的nfs共享目录"/nfs"到客户端"/mnt/nfs"下
[root@localhost ~]# showmount -e 192.168.1.10 //查看可用共享文件 Export list for 192.168.1.10: /nfs (everyone) [root@localhost ~]# mkdir /mnt/nfs [root@localhost ~]# mount -t nfs 192.168.1.10:/nfs /mnt/nfs [root@localhost ~]# ls /mnt/nfs/ 1 2 [root@localhost ~]# cat /mnt/nfs/1 hello
或者将挂载信息写入"/etc/fstab"中，开机自动挂载
[root@localhost ~]# vim /etc/fstab # # /etc/fstab # Created by anaconda on Sat Feb 13 09:29:45 2016 # # Accessible filesystems, by reference, are maintained under '/dev/disk' # See man pages fstab(5), findfs(8), mount(8) and/or blkid(8) for more info # /dev/mapper/rhel-root / xfs defaults 1 1 UUID=8d922f42-25a9-42aa-aee2-6e29b1ac7f1a /boot xfs defaults 1 2 /dev/mapper/rhel-swap swap swap defaults 0 0 /dev/cdrom /media/cdrom iso9660 defaults 0 0 192.168.1.10:/nfs /mnt/nfs nfs defaults 0 0
