7.6 yum更换国内源

 

默认.repo文件中的源为国外的网址，下载速度较慢，可以更换国内源

步骤：

1 删除原来的.repo文件

2 下载国内源的.repo文件到yum.repos.d目录下

[[email protected] ~]# curl -O http://mirrors.163.com/.help/CentOS7-Base-163.repo

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current

                                 Dload  Upload   Total   Spent    Left  Speed

100  1572  100  1572    0     0   9860      0 --:--:-- --:--:-- --:--:--  9886

[[email protected] ~]# ls

anaconda-ks.cfg  CentOS7-Base-163.repo

[[email protected] ~]# cp CentOS7-Base-163.repo /etc/yum.repos.d

[[email protected] ~]# cd  !$

cd  /etc/yum.repos.d

[[email protected] yum.repos.d]# ls

CentOS7-Base-163.repo  CentOS-fasttrack.repo  CentOS-Vault.repo

CentOS-CR.repo         CentOS-Media.repo

CentOS-Debuginfo.repo  CentOS-Sources.repo

[[email protected] yum.repos.d]# mv CentOS7-Base-163.repo CentOS7-Base-163.repo.123

修改.repo文件名导致系统无法识别

[[email protected] yum.repos.d]# yum install zsh zsh无法正常安装

已加载插件：fastestmirror

Loading mirror speeds from cached hostfile

There are no enabled repos.

 Run "yum repolist all" to see the repos you have.

 To enable Red Hat Subscription Management repositories:

     subscription-manager repos --enable <repo>

 To enable custom repositories:

     yum-config-manager --enable <repo>

[[email protected] yum.repos.d]# yum repolist all 此时查看仓库发现所有仓库处于禁用状态

[[email protected] yum.repos.d]# mv CentOS7-Base-163.repo.123 CentOS7-Base-163.repo 改回原来正确的文件名

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

已加载插件：fastestmirror

Repodata is over 2 weeks old. Install yum-cron? Or run: yum makecache fast

正在清理软件源： base extras updates

Cleaning up everything

Maybe you want: rm -rf /var/cache/yum, to also free up space taken by orphaned data from disabled or removed repos

Cleaning up list of fastest mirrors

[[email protected] yum.repos.d]# yum install zsh 此时zsh可以正常安装，由于先前清空了缓存，此时会重新生成缓存

[[email protected] yum.repos.d]# yum repolist all 此时与163.com有关的源为启用状态

[[email protected] yum.repos.d]# yum list 查看发现出现了base仓库中的包
