设置开机自动启动

 

[root@Raygussie ~]# systemctl enable --now autofs
Created symlink /etc/systemd/system/multi-user.target.wants/autofs.service → /usr/lib/systemd/system/autofs.service.

 

 

编辑主配置文件

[root@Raygussie ~]# vi /etc/auto.master

#
# Sample auto.master file
# This is a 'master' automounter map and it has the following format:
# mount-point [map-type[,format]:]map [options]
# For details of the format look at auto.master(5).
#
/misc   /etc/auto.misc
/media  /etc/cdrom.misc      //主配置挂载路径

 

编辑子配置文件

 

[root@Raygussie ~]# vi /etc/cdrom.misc

cdrom -fstype=iso9660,ro,nosuid,nodev :/dev/cdrom

 

 

 

重启autofs

[root@Raygussie ~]# systemctl restart autofs
[root@Raygussie ~]# df -h

[root@luyi ~]# mkdir -p /nfsfile/test
[root@luyi ~]# echo "i am chinese" > /nfsfile/test/file

 

nfs服务端文件配置

[root@luyi ~]# vi /etc/exports

/nfsfile/test 192.168.186.* (rw,sync,root_squash)

nfs客户端配置

//安装nfs-utils和rpcbind
[root@Raygussie ~]# yum -y install nfs-utils rpcbind

使用showmount命令查询NFS服务端共享信息（建议关闭防火墙）

[root@Raygussie ~]# showmount -e 192.168.186.131
Export list for 192.168.186.131:
/nfsfile/test (everyone)

创建挂载目录

[root@Raygussie ~]# mkdir /nfsfile
[root@Raygussie ~]# mount 192.168.186.131:/nfsfile /nfsfile
[root@Raygussie ~]# cat /nfsfile/test/file
i am chinese
