centos6.7配置本地yum源总结

Posted 2021-01-01

1. 建立ISO文件存放目录(/repo/iso)和ISO文件的挂载目录(/repo/centos)
   [[email protected] yum.repos.d]# mkdir -p /repo/iso
   [[email protected] yum.repos.d]# mkdir -p /mnt/cdrom 建立光驱的挂载目录
   [[email protected] yum.repos.d]# mkdir -p /repo/centos 本地ISO的挂载目录

2.可以直接上传ISO文件或者挂载本地光盘！

3. 挂载ISO文件

[[email protected] yum.repos.d]# mount -t iso9660 /dev/cdrom /mnt/cdrom
[[email protected] yum.repos.d]# mount -o loop /repo/iso/CentOS-6.7-x86_64-bin-DVD2.iso /repo/centos

[[email protected] ~]# df -h
Filesystem Size Used Avail Use% Mounted on
/dev/sda5 44G 12G 31G 27% /
tmpfs 1.2G 72K 1.2G 1% /dev/shm
/dev/sda1 113M 41M 67M 38% /boot
/dev/sda3 3.8G 10M 3.6G 1% /tmp
/repo/iso/CentOS-6.7-x86_64-bin-DVD1.iso
3.7G 3.7G 0 100% /repo/centos

4. 确保系统中已经安装了yum相关软件包
   [[email protected] ~]# rpm -qa |grep yum
   yum-3.2.29-69.el6.centos.noarch
   yum-plugin-security-1.1.30-30.el6.noarch
   PackageKit-yum-0.5.8-25.el6.x86_64
   yum-utils-1.1.30-30.el6.noarch
   yum-metadata-parser-1.1.2-16.el6.x86_64
   PackageKit-yum-plugin-0.5.8-25.el6.x86_64
   yum-plugin-fastestmirror-1.1.30-30.el6.noarch
   版本号可能有所不同, 如果缺少, 请自行安装(这些包基本都默认安装了).

5. 编辑repo文件
   [[email protected] ~]# cd /etc/yum.repos.d/
   [[email protected] yum.repos.d]# ll
   total 24
   -rw-r--r--. 1 root root 1991 Aug 4 2015 CentOS-Base.repo
   -rw-r--r--. 1 root root 647 Aug 4 2015 CentOS-Debuginfo.repo
   -rw-r--r--. 1 root root 289 Aug 4 2015 CentOS-fasttrack.repo
   -rw-r--r--. 1 root root 630 Aug 4 2015 CentOS-Media.repo
   -rw-r--r--. 1 root root 6259 Aug 4 2015 CentOS-Vault.repo
   [[email protected] yum.repos.d]# mv CentOS-Base.repo CentOS-Base.repo.bak
   [[email protected] yum.repos.d]# mv CentOS-Debuginfo.repo CentOS-Debuginfo.repo.bak
   [[email protected] yum.repos.d]# mv CentOS-fasttrack.repo CentOS-fasttrack.repo.bak
   [[email protected] yum.repos.d]# mv CentOS-Vault.repo CentOS-Vault.repo.bak
   [[email protected] yum.repos.d]# ll
   total 28
   -rw-r--r--. 1 root root 1991 Aug 4 2015 CentOS-Base.repo.bak
   -rw-r--r--. 1 root root 647 Jun 1 22:48 CentOS-Debuginfo.repo.bak
   -rw-r--r--. 1 root root 289 Aug 4 2015 CentOS-fasttrack.repo.bak
   -rw-r--r--. 1 root root 630 Aug 4 2015 CentOS-Media.repo
   -rw-r--r--. 1 root root 6259 Aug 4 2015 CentOS-Vault.repo.bak
   说明：/etc/yum.repos.d/ 下的文件都是有用的，防止以后有用，这里我们mv改名做备份。
   CentOS-Media 这个是使用光盘挂载后调用的文件
   CentOS-Base 这个是联网后基础的源
   CentOS-Vault 这个是最近新版本的加入的老版本的yum源配置
   CentOS-Debuginfo debug包尤其和内核相关的更新和软件安装

[[email protected] yum.repos.d]# cat rhel6-public.repo
[rhel6]
name=rhel6
baseurl=file:///mnt/cdrom
enabled=0
gpgcheck=1

备注：enabled=1启用本地yum源，有时候当用1时会报如下错误：Errno 14 Could not open/read repomd.xml 错误，此时需要将enabled=0即可解决！

6.清空yum缓存
[[email protected] yum.repos.d]# yum clean all
Loaded plugins: fastestmirror, refresh-packagekit, security
Cleaning repos: c6-media
Cleaning up Everything
[[email protected] yum.repos.d]# yum makecache
Metadata Cache Created

7.生成列表
[[email protected] yum.repos.d]# yum list

8. 安装
   [[email protected] yum.repos.d]# yum -y install autoconf automake binutils-devel bison cpp dos2unix ftp gcc gcc-c++ lrzsz python-devel
