Posted 2020-09-21 Vathe

系统环境

系统平台：CentOS release 6.8 (Final)

NFS Server IP：172.16.55.6

防火墙关闭

SELinux=disabled

 

安装NFS程序包

1.查看系统是否已经安装

[[email protected] vsftpd]$ yum list nfs-utils 
已加载插件：fastestmirror, security
Loading mirror speeds from cached hostfile
已安装的软件包
nfs-utils.x86_64                                 1:1.2.3-70.el6                                  @net

2.如果没有安装nfs，则安装nfs程序包

[[email protected] vsftpd]$ yum install -y nfs-utils

配置共享目录

[[email protected] vsftpd]$ mkdir -pv /shared/pub               
mkdir: 已创建目录 "/shared"
mkdir: 已创建目录 "/shared/pub"
[[email protected] vsftpd]$ vim /etc/exports                    # 配置
      /shared/pub  172.16.55.7(rw) 172.16.0.0/16(ro)

[[email protected] vsftpd]$ exportfs -rav

[[email protected] pub]$ showmount -e localhost # 查看 
Export list for localhost: /shared/pub 172.16.0.0/16

在其他主机挂载该文件目录

[[email protected] vsftpd]#mkdir /shared
[[email protected] vsftpd]#mount -t nfs -w 172.16.55.6:/shared/ /shared/   #以读写方式挂载
[[email protected] vsftpd]#df
