05 linux中yum源报错
清华大学开源镜像站:https://mirrors.tuna.tsinghua.edu.cn/centos-vault/6.9/os/x86_64/
首先确保我的虚拟机网络是通的。
网卡域名服务器配置:
cat /etc/sysconfig/network-scripts/ifcfg-eth0
然后cat /etc/resolv.conf,这里的nameserver与网卡配置中的DNS配置对应就可。
测试网络是否通:ping www.baidu.com
网络是通的,排除DNS域名,防火墙没关,网络适配器必须修改为桥接这种可能性。
网上还有些人说是/etc/yum.repos.d/CentOS-Base.repo这个文件的配置问题,注释掉mirrorlist这个配置项就能成功,试下看看。
mirrorlist都注释掉了,执行sudo yum update试试
还是没能成功
把源站点配置改为国内清华大学站点https://mirrors.tuna.tsinghua.edu.cn/centos-vault找到对应的Centos版本,最终成功。
这里参考了这位老兄的文章,https://blog.csdn.net/fangeqin/article/details/106170479?utm_medium=distribute.pc_relevant.none-task-blog-BlogCommendFromBaidu-3.control&depth_1-utm_source=distribute.pc_relevant.none-task-blog-BlogCommendFromBaidu-3.control
确认清华大学站点能访问:
修改yum源站点配置:vi /etc/yum.repos.d/CentOS-Base.repo
对照清华大学镜像站中的目录修改后如下:

解决办法就是把本地源关闭:将/etc/yum.repos.d/CentOS-Media.repo里面的enabled=1改成enabled=0即可,因为yum寻包的顺序应该先是本地源,再寻网络源。
