1.制作YUM源
先关闭相关安全设置，安装vsftpd

[root@rhel7 ~]# firewall-cmd --set-default-zone=trusted  设置防火墙受信

[root@rhel7 ~]# setenforce 0

[root@rhel7 ~]# systemctl start vsftpd  启动已经安装的vsftpd

[root@rhel7 ~]# systemctl enable vsftpd

[root@rhel7 ~]# ls /var/ftp/  共享目录

pub

挂载到共享目录

[root@rhel7 ~]# mkdir /var/ftp/dvd

[root@rhel7 ~]# umount /mnt

[root@rhel7 ~]# mount /dev/cdrom /var/ftp/dvd/

mount: /dev/sr0 is write-protected, mounting read-only

[root@rhel7 ~]# ls /var/ftp/dvd/

addons  GPL       LiveOS      release-notes            RPM-GPG-KEY-redhat-release

EFI     images    media.repo  repodata                 TRANS.TBL

EULA    isolinux  Packages    RPM-GPG-KEY-redhat-beta

[root@rhel7 ~]# rm -rf /var/ftp/pub/

对新增的安装包目录生成包的元数据(把包中依赖关系统计)

createrepo -v 目录 (会在目录下生成一个repodata的原数据信息)

配置yum路径特性

[root@rhel7 ~]# cat /etc/yum.repos.d/file.repo

[dvd]

name=dvd

baseurl=ftp://192.168.56.133/dvd

enabled=1

gpgcheck=0

生成yum

[root@rhel7 ~]# yum clean all

[root@rhel7 ~]# yum makecache

2.YUM命令简单使用
查询安装包

[root@rhel7 ~]# yum search vsftpd

vsftpd.x86_64 : Very Secure Ftp Daemon

[root@rhel7 ~]# yum list vsftpd   可以知道包的安装情况

vsftpd.x86_64                                  3.0.2-9.el7                                  installe

清除提示信息

[root@rhel7 ~]# yum list subscript*

Loaded plugins: product-id, subscription-manager  #redhat系统是免费使用的,但是服务是收费的

This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.

[root@rhel7 ~]# yum remove subscript* -y

查找命令对应的安装包----常用

[root@rhel7 ~]# yum whatprovides */ifconfig   #*/是因为包安装完后,会放在各个不同目录下,这里是可能在那个目录下

net-tools-2.0-0.17.20131004git.el7.x86_64 : Basic networking tools

Repo        : dvd

Matched from:

Filename    : /sbin/ifconfig

要实现某个功能,这个功能是由很多个包组成

[root@rhel7 ~]# yum grouplist

There is no installed groups file.

Maybe run: yum groups mark convert (see man yum)

Available environment groups:

   Minimal Install

   Infrastructure Server

   File and Print Server

   Basic Web Server

   Virtualization Host

   Server with GUI

Available Groups:

   Compatibility Libraries

   Console Internet Tools

   Development Tools

   Graphical Administration Tools

   Legacy UNIX Compatibility

   Scientific Support

   Security Tools

   Smart Card Support

   System Administration Tools

   System Management

Done

[root@rhel7 ~]# yum grouplist virtual*

There is no installed groups file.

Maybe run: yum groups mark convert (see man yum)

Available environment groups:

   Virtualization Host

Done

[root@rhel7 ~]# yum groupinstall virtual* -y

禁用yum源

[root@rhel7 ~]# yum list ceph --disablerepo=ceph

[root@rhel7 ~]# yum list ceph --disablerepo=* --enablerepo=ceph 禁用所有源,只使用ceph

安装时设置下载包存放的路径(需要搭建本地源时,可以下载所有包)

[root@rhel7 ~]# yum install ceph -y --downloaddir=/opt --downonly #下载到/opt,只是下载

yum报错：Bad id for repo

“[centos - updates]”的格式不对，“centos”，“-”，“updates”之间是不允许存在空格的，删除即可。
