yum搭建

一.yum命令

yum   install            softwarename    ##安装

          repolist                                      ##列出设定yum源信息

          remove         softwarename    ##卸载
          list                 softwarename    ##查看软件源中是否有此软件
          list all                                         ##列出所有软件名称

          list installd                                 ##列出已经安装的软件名称

          list available                             ##列出可以用yum安装的软件名称

          clean all                                    ##清空yum缓存

          search           softwareinfo      ##根据软件信息搜索软件名字

          whatprovides filename           ##在yum源中查找包含filename文件的软件包
          update                                      ##更新软件

          history                                       ##查看系统软件改变历史

          reinstall          softwarename   ##重新安装
          info                 softwarename   ##查看软件信息
          groups list                                 ##查看软件组信息
          groups info    softwaregroup   ##查看软件组包含的软件
          groups install softwaregroup   ##安装组件

          groups remove  softwaregroup   ##卸载组件

二.yum源搭建

寻找一个和系统匹配的镜像文件到系统

[[email protected] ~]# mkdir /iso

[[email protected] ~]# mv /home/kiosk/Desktop/*.iso  /iso

[[email protected] ~]# mkdir /source7.0

[[email protected] ~]# mkdir /source7.2

[[email protected] ~]# mount /iso/rhel-server-7.0-x86_64-dvd.iso /source7.0  ##挂载虚拟的yum源

mount: /dev/loop0 is write-protected, mounting read-only

[[email protected] ~]# mount /iso/rhel-server-7.2-x86_64-dvd.iso /source7.2  ##挂载真机的yum源

mount: /dev/loop1 is write-protected, mounting read-only

[[email protected] ~]# cd /etc/yum.repos.d/

[[email protected] yum.repos.d]# mkdir /repobackup

[[email protected] yum.repos.d]# mv * /repobackup

[[email protected] yum.repos.d]# vim yum.repo

[[email protected] yum.repos.d]# yum clean all

三.yum源

在本地yum源配置完成之后安装apache ##用来共享

yum install httpd

systemctl start httpd

systemctl enable httpd

systemctl stop firewalld

systemctl disable firewalld

mkdir /var/www/html/source7.0 /var/www/html/source7.2

2.挂载镜像

mount /iso/rhel-server-7.0-x86_64-dvd.iso /var/www/html/source7.0

mount /iso/rhel-server-7.2-x86_64-dvd.iso /var/www/html/source7.2

vim /etc/rc.d/rc.local  ##开机自动挂载

chmod +x /etc/rc.d/rc.local

3.在虚拟机中访问测试

在浏览器中输入地址

http：//ip/source7.0

http：//172.25.254.16/source7.0

http：//172.25.254.16/source7.2

4.配置虚拟机yum

rm -fr /etc/yum.repos.d/*

vim /etc/yum.repos.d/yum.repo
