参考 https://arstech.net/centos-6-error-yumrepo-error-all-mirror-urls-are-not-using-ftp-http/ 

【1】报错现场；

原因， 软件镜像地址有误，需要手工录入；

2、编辑文件， /etc/yum.repos.d/CentOS-Base.repo.

找到 base， updates， extras 域，并 注释掉 mirrorlist， baseurl； 

然后复制 baseurl做修改，如下：（注意我的centos 版本是6.5 ，所以需要做对应修改）

# CentOS-Base.repo2 #3 # The mirror system uses the connecting IP address of the client and the4 # update status of each mirror to pick mirrors that are updated to and5 # geographically close to the client.  You should use this for CentOS updates6 # unless you are manually picking other mirrors.7 #8 # If the mirrorlist= does not work for you, as a fall back you can try the9 # remarked out baseurl= line instead.10 #11 #12 13 [base]14 name=CentOS-$releasever - Base15 # mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os16 # baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/17 baseurl=http://vault.centos.org/6.5/os/$basearch/18 gpgcheck=119 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-620 21 #released updates22 [updates]23 name=CentOS-$releasever - Updates24 # mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates25 # baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/26 baseurl=http://vault.centos.org/6.5/updates/$basearch/27 gpgcheck=128 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-629 30 #additional packages that may be useful31 [extras]32 name=CentOS-$releasever - Extras33 # mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras34 # baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/35 baseurl=http://vault.centos.org/6.5/extras/$basearch/36 gpgcheck=137 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-638 39 #additional packages that extend functionality of existing packages40 [centosplus]41 name=CentOS-$releasever - Plus42 mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus43 #baseurl=http://mirror.centos.org/centos/$releasever/centosplus/$basearch/44 gpgcheck=145 enabled=046 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-647 48 #contrib - packages by Centos Users49 [contrib]50 name=CentOS-$releasever - Contrib51 mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=contrib52 #baseurl=http://mirror.centos.org/centos/$releasever/contrib/$basearch/53 gpgcheck=154 enabled=055 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-6

 

3、清空缓存

yum clean all 

4 更新  yum update 

bingo。
