CentOS8设置国内镜像源（阿里云镜像）

CentOS8设置国内镜像源（阿里云）

1、备份原有配置

[root@localhost ~]# mkdir /etc/yum.repos.d.bak
[root@localhost ~]# mv /etc/yum.repos.d/* /etc/yum.repos.d.bak/
[root@localhost ~]# ll /etc/yum.repos.d/
[root@localhost ~]# ll /etc/yum.repos.d.bak/


2、下载阿里云镜像配置

[root@localhost ~]# curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-8.repo


3、修改配置文件

• 删除"mirrors.cloud.aliyuncs.com" 及 "mirrors.aliyuncs.com" 字符串所在的行

[root@localhost ~]# sed -i -e '/mirrors.cloud.aliyuncs.com/d' -e '/mirrors.aliyuncs.com/d' /etc/yum.repos.d/CentOS-Base.repo


• 替换 "releasever/" 为 "releasever-stream/"

[root@localhost ~]# sed -i 's/releasever\//releasever-stream\//g' /etc/yum.repos.d/CentOS-Base.repo


3、重置缓存

[root@localhost ~]# yum clean all
[root@localhost ~]# yum makecache


4、测试

[root@localhost ~]# yum -y install dos2unix
