centos6更换yum源

1、修改/etc/yum.repos.d/CentOS-Base.repo （原始文件另存为CentOS-Base.repo.old）

[base]name=CentOS-6
failovermethod=priority
baseurl=https://vault./6.9/os/x86_64/
gpgcheck=0

2、修改/etc/yum.repos.d/epel.repo

[epel]
name=Extra Packages for Enterprise Linux 6 - $basearch
baseurl=https://archives./pub/archive/epel/6/$basearch
failovermethod=priority
enabled=1
gpgcheck=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
 
[epel-debuginfo]
name=Extra Packages for Enterprise Linux 6 - $basearch - Debug
baseurl=https://archives./pub/archive/epel/6/$basearch/debug
failovermethod=priority
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
gpgcheck=0
 
[epel-source]
name=Extra Packages for Enterprise Linux 6 - $basearch - Source
baseurl=https://archives./pub/archive/epel/6/SRPMS
failovermethod=priority
enabled=0
gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-EPEL-6
gpgcheck=0
