清华的源不可用,导致了一堆堆的问题
首先,检查 /etc/yum.repos.d/下边有多少个 repo 文件
[root@localhost ~]# cd /etc/yum.repo.d/
[root@localhost yum.repos.d]# ls
CentOS-Base.repo CentOS-CR.repo CentOS-fasttrack.repo CentOS-Sources.repo epel.repo gitlab_gitlab-ce.repo MysqL-community-source.repo
CentOS-Base.repo.bak CentOS-Debuginfo.repo CentOS-Media.repo CentOS-Vault.repo epel-testing.repo MysqL-community.repo Nginx.repo
经检查,发现很多的repo文件
[root@localhost ~]# yum clean all
[root@localhost ~]# yum makecache

现在需要做的就是删除了,除了 CentOS-Base.repo,其他的都删除
[root@localhost yum.repos.d]# rm -y CentOS-CR.repo
[root@localhost yum.repos.d]# rm -y CentOS-fasttrack.repo
[root@localhost yum.repos.d]# rm -y CentOS-Sources.repo
[root@localhost yum.repos.d]# rm -y epel.repo
[root@localhost yum.repos.d]# rm -y gitlab_gitlab-ce.repo
[root@localhost yum.repos.d]# rm -y MysqL-community-source.repo
[root@localhost yum.repos.d]# rm -y CentOS-Debuginfo.repo
[root@localhost yum.repos.d]# rm -y CentOS-Media.repo
[root@localhost yum.repos.d]# rm -y epel-testing.repo
[root@localhost yum.repos.d]# rm -y MysqL-community.repo
[root@localhost yum.repos.d]# rm -y Nginx.repo
删除之后
[root@localhost yum.repos.d]# yum makecache
