1.使用网络安装资源安装软件

1.切换目录

cd /etc/yum.repos.d

2.建立文件

vim westos.repo			##文件必须以.repo结尾

[redhat]			##仓库名称
name=haha			##对软件源的描述
baseurl=http://172.25.254.250/rhel7.3/x86_64/dvd/##基础路径网络安装源
gpgcheck=0			##0取消校验步骤	1不取消校验步骤

yum clean all 			##清空系统中原有的yum信息

3.yum repolist ##yum列表

[root@software_install ~]# yum repolist
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-
: manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
repo id                               repo name                           status
redhat                                test                                4,751
repolist: 4,751

2.配置本地yum源

1.获取一个与本机系统版本一致的系统镜像

建立/iso/将镜像文件放入，这样更安全
[root@foundation32 ~]# mkdir /iso
[root@foundation32 ~]# mv /home/kiosk/Desktop/rhel-server-7.3-x86_64-dvd.iso  /iso

2.挂载镜像

mount   /xxx/xxxx.iso	/rhel7.3
[root@foundation32 ~]# mkdir /redhatyum
[root@foundation32 ~]# mount /iso/rhel-server-7.3-x86_64-dvd.iso /redhatyum/
mount: /dev/loop0 is write-protected, mounting read-only

3.设定永久挂载

vim /etc/rc.d/rc.local
mount /xx/xx.iso	/rhel7.3

chmod 755 /etc/rc.d/rc.local		##在系统开机时会自动执行此脚本

4.设定系统安装源指向

mkdir /etc/yum.repos.d/backup
mv /etc/yum.repos.d/* /etc/yum.repos.d/backup
vim /etc/yum.repos.d/westos.repo
1 [rhel7.3]
2 name=rhel7.3
3 baseurl=file:///var/www/html/westos/
4 gpgcheck=0

yum clean all
yum install httpd
[root@foundation32 ~]# cd /etc/yum.repos.d/
[root@foundation32 yum.repos.d]# ls
redhat.repo  rhel-dvd.repo  rht-ucf.repo
[root@foundation32 yum.repos.d]# mkdir backup
[root@foundation32 yum.repos.d]# ls
backup  redhat.repo  rhel-dvd.repo  rht-ucf.repo
[root@foundation32 yum.repos.d]# mv * backup/
mv: cannot move ‘backup’ to a subdirectory of itself, ‘backup/backup’
[root@foundation32 yum.repos.d]# vim westos.repo
[root@foundation32 yum.repos.d]# yum repolist
Loaded plugins: langpacks, product-id, search-disabled-repos, subscription-
: manager
This system is not registered to Red Hat Subscription Management. You can use subscription-manager to register.
Repository 'rhel7.3': Error parsing config: Error parsing "baseurl = 'file:// /redhatyum'": URL must be http, ftp, file or https not ""
repolist: 0

3.共享型yum源的部署

1.在一台已经连接好本地yum源的主机中安装http

yum install httpd

2.配置网络yum源

systemctl start httpd
systemctl enable httpd
systemctl stop firewalld.service
systemctl disable firewalld.service

mkdir /var/www/html/westos mount /iso/rhel-server-7.3-x86_64-dvd.iso /var/www/html/westos/ vim /etc/rc.d/rc.local 14 mount /iso/rhel-server-7.3-x86_64-dvd.iso /var/www/html/westos/ chmod +x /etc/rc.d/rc.local

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

测试：

在浏览器输入地址
http://ip/rhel7.3

4.yum命令

1.yum命令的使用必须是在yum源搭建成功后才能正常运行

2.yum命令详细用法

5.用rpm命令处理软件

rpm

6.软件包名称详解

kolourpaint-4.10.5-4.el7.x86_64.rpm
[1]           [2]    [3] [4]    [5]

[1]软件名称
[2]版本
[3]适用系统
[4]架构
[5]适用rpm体系软件

7.第三方软件仓库的搭建

1.

将所有的rpm包放到一个目录中

2.

createrepo -v /存放软件包的目录			##命令执行成功会生成repodate目录

3.vim /etc/yum.epos.d/yum.repo

[software]
name=third software
baseurl=file:///software
gpgcheck=0

yum clean all
yum list linux
yum install kolourpaint
