基本使用：
以在Centos7.9为例：
1.安装autofs
yum install -y autofs
2.主配置文件
cat /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 # # NOTE: mounts done from a hosts map will be mounted with the # "nosuid" and "nodev" options unless the "suid" and "dev" # options are explicitly given. # /net -hosts # # Include /etc/auto.master.d/*.autofs # The included files must conform to the format of this file. # +dir:/etc/auto.master.d # # Include central master map if it can be found using # nsswitch sources. # # Note that if there are entries for /net or /misc (as # above) in the included master map any keys that are the # same will not be seen as the first read key seen takes # precedence. # +auto.master
3.基本使用方法：
3.1.使用相对路径时的语法：
/etc/auto.master格式：
挂载点的dirname 指定配置文件路径
指定配置文件格式
挂载点的basename 挂载选项 被挂载的位置
3.2.使用绝对路径的语法
/etc/auto.master格式：
/- 指定配置文件路径
指定配置文件格式
挂载点绝对路径 挂载选项 被挂载的位置
4.测试使用（使用nfs）
nfs地址：192.168.1.237 nfs配置文件内容： /nfs/absolutely 192.168.1.*(rw,sync,all_squash)
/nfs/relative 192.168.1.*(rw,sync,all_squash)
4.1.使用相对路径
vim /etc/auto.master
# 在末尾加入
/nfs /etc/relative.misc
vim /etc/relative.misc
relative -fstype=nfs,rw,sync,no_root_squash 192.168.1.237:/nfs/relative
重启autofs
systemctl restart autofs
4.2.使用绝对路径
mkdir /test/absolutely -p
vim /etc/master
/- /etc/absolutely.misc
vim /etc/absolutely.misc
/test/absolutely -fstype=nfs,rw,sync,no_root_squash 192.168.1.237:/nfs/absolutely
重启autofs
systemctl restart autofs
