更换yum源，并生成缓存

进入正题
关闭防火墙，禁止开机启动

[[email protected] ~]# systemctl stop firewalld.service
[[email protected] ~]# systemctl disable firewalld.service
Removed symlink /etc/systemd/system/multi-user.target.wants/firewalld.service.
Removed symlink /etc/systemd/system/dbus-org.fedoraproject.FirewallD1.service.

查看是否安装nfs、rpcbind（若有安装，则会显示内容）

[[email protected] ~]# rpm -qa |grep nfs
[[email protected] ~]# rpm -qa |grep rpcbind
[[email protected] ~]# 

安装NFS

[[email protected] ~]# yum -y install nfs-utils rpcbind
已安装:
  nfs-utils.x86_64 1:1.3.0-0.66.el7_8                                                                                                                                      rpcbind.x86_64 0:0.2.0-49.el7                                                                                                                                     

作为依赖被安装:
gssproxy.x86_64 0:0.7.0-28.el7           keyutils.x86_64 0:1.5.8-3.el7          libbasicobjects.x86_64 0:0.1.1-32.el7        libcollection.x86_64 0:0.7.0-32.el7       libevent.x86_64 0:2.0.21-4.el7       libini_config.x86_64 0:1.3.1-32.el7       libnfsidmap.x86_64 0:0.25-19.el7       libpath_utils.x86_64 0:0.2.1-32.el7      
libref_array.x86_64 0:0.1.5-32.el7       libtirpc.x86_64 0:0.2.4-0.16.el7       
libverto-libevent.x86_64 0:0.2.5-4.el7       quota.x86_64 1:4.01-19.el7                quota-nls.noarch 1:4.01-19.el7       tcp_wrappers.x86_64 0:7.6-77.el7 
[[email protected] ~]# 

启动NFS

[[email protected] ~]# systemctl start rpcbind
[[email protected] ~]# systemctl start nfs

新建NFS存储目录data，设置共享目录权限

[[email protected] ~]# ls
anaconda-ks.cfg
[[email protected] ~]# mkdir data
[[email protected] ~]# ls
anaconda-ks.cfg  data
[[email protected] ~]# vi /etc/exports
插入加入以下内容
/root/data/ 192.168.1.2/32(insecure,rw,sync,no_root_squash) 192.168.10.8(insecure,rw,sync,no_root_squash)

fsid=0：只能共享一个目录，此目录将成为NFS服务器的根目录。
rw：目录读写
sync：传输效率低，可保证数据一致性
async：传输效率高

重新加载配置、重启NFS服务器

[[email protected] ~]# exportfs -rv
[[email protected] ~]# systemctl restart nfs.service

至此，NFS搭建完成
