linux基础-misc目录

misc目录

• 该目录的作用是，可以自动挂在cdrom
• 直接进入该目录/misc/cd即可访问cdrom内容
• centos7一般情况下是没有misc文件的，需要安装RPM包
• 对应包autofs-5.0.7-83.el7.x86_64.rpm

安装misc

1. 安装相应rpm包

[root@centos7 Packages]$ls | grep auto*fs
autofs-5.0.7-83.el7.x86_64.rpm
libsss_autofs-1.16.0-19.el7.x86_64.rpm
[root@centos7 Packages]$rpm -ivh autofs-5.0.7-83.el7.x86_64.rpm 
warning: autofs-5.0.7-83.el7.x86_64.rpm: Header V3 RSA/SHA256 Signature, key ID f4a80eb5: NOKEY
Preparing...                          ################################# [100%]
	package autofs-1:5.0.7-83.el7.x86_64 is already installed

2. 设置开机启动

[root@centos7 /]$systemctl enable autofs
Created symlink from /etc/systemd/system/multi-user.target.wants/autofs.service to /usr/lib/systemd/system/autofs.service.

3. 测试

[root@centos7 ~]#cd /misc/cd
[root@centos7 cd]#ls
