Linux：配置客户端autofs服务

安装autofs软件

[root@server200 ~]# dnf install autofs -y

开启并设置开机自启autofs服务

[root@server200 ~]# systemctl enable --now autofs

访问默认autofs挂载机制

当autofs启动后系统默认会在/net目录中访问nfs服务器

[root@server200 ~]# cd /net/172.25.254.100
[root@server200 ~]# ls
data1	data2	data3

设定动态卸载时间

默认autofs在发现限制资源闲置后会在300秒自动卸载，此设定可以自行设定

[root@server200 ~]# vim /etc/autofs.conf*** ***
timeout = 5
*** ***[root@server200 ~]# systemctl restart autofs

总体实现

[root@server200 ~]# dnf install autofs
[root@server200 ~]# systemctl enable --now autofs.service
