NFS实现linux之间的文件共享

NFS（网络文件系统）服务可以将远程 Linux 系统上的文件共享资源挂载到本地主机的目录上，从而使得本地主机（Linux 客户端）基于 TCP/IP 协议，像使用本地主机上的资源那样读写远程 Linux 系统上的共享文件。

1. 安装NFS服务端软件包

[root@linuxprobe ~]# yum install nfs-utils
Loaded plugins: langpacks, product-id, subscription-manager
(1/2): rhel7/group_gz | 134 kB 00:00
(2/2): rhel7/primary_db | 3.4 MB 00:00
Package 1:nfs-utils-1.3.0-0.el7.x86_64 already installed and latest version
Nothing to do

2.创建NFS服务端共享文件夹

[root@linuxprobe ~]# mkdir /nfsfile
[root@linuxprobe ~]# chmod -Rf 777 /nfsfile
[root@linuxprobe ~]# echo "welcome to linuxprobe.com" > /nfsfile/readme

3.配置NFS服务端

[root@linuxprobe ~]# vim /etc/exports
/nfsfile 192.168.10.*(rw,sync,root_squash)

4. 重启NFS服务端相关服务

[root@linuxprobe ~]# systemctl restart rpcbind
[root@linuxprobe ~]# systemctl enable rpcbind
[root@linuxprobe ~]# systemctl start nfs-server
[root@linuxprobe ~]# systemctl enable nfs-server
ln -s '/usr/lib/systemd/system/nfs-server.service' '/etc/systemd/system/nfs.
target.wants/nfs-server.service'

5. NFS客户端查看挂载信息

[root@linuxprobe ~]# showmount -e 192.168.0.31
Export list for 192.168.0.31:
/nfsfile 192.168.0.*

6.NFS客户端执行挂载并设置为永久生效

[root@linuxprobe ~]# mkdir /nfsfile
[root@linuxprobe ~]# mount -t nfs 192.168.10.10:/nfsfile /nfsfile

[root@linuxprobe ~]# vim /etc/fstab
