CentOS配置本地yum源/阿里雲yum源/163yuan源並配置yum源的優先級
1.查看本地yum源
2.把默認yum源備份
mkdir /opt/centos-yum.bak
mv /etc/yum.repos.d/* /opt/centos-yum.bak/
一、用Centos鏡像搭建本地yum源
1.掛載CentOS鏡像文件
mount -t iso9660 /dev/sr0 /opt/centos
2.寫repo文件並指向鏡像的掛載目錄
vi /etc/yum.repos.d/local.repo
[
local
]
name=
local
baseurl=
file
:
///opt/centos
enabled=1
gpgcheck=0
3.清除緩存
yum clean all
yum makecache
yum list
二、把默認的CentOS yum源修改成國內的aliyun yum源(yum install wget -y )
1.下載aliyun yum源repo文件(對應自己的系統版本下載即可)
#各系統版本repo文件對應的下載操作
CentOS 5
wget -O
/etc/yum
.repos.d
/CentOS-Base
.repo http:
//mirrors
.aliyun.com
/repo/Centos-5
.repo
CentOS 6
wget -O
/etc/yum
.repos.d
/CentOS-Base
.repo http:
//mirrors
.aliyun.com
/repo/Centos-6
.repo
CentOS 7
wget -O
/etc/yum
.repos.d
/CentOS-Base
.repo http:
//mirrors
.aliyun.com
/repo/Centos-7
.repo
2. cat /etc/redhat-release //查看系統的版本

3.下載對應的YUM源
4.清除緩存
yum clean all
yum makecache
yum list
三、把默認的CentOS yum源修改成國內的163源
1.下載163 yum源repo文件
#各系統版本repo文件對應的下載操作
CentOS 5
wget -O
/etc/yum
.repos.d
/CentOS5-Base-163
.repo http:
//mirrors
.163.com/.help
/CentOS5-Base-163
.repo
CentOS 6
wget -O
/etc/yum
.repos.d
/CentOS6-Base-163
.repo http:
//mirrors
.163.com/.help
/CentOS6-Base-163
.repo
CentOS 7
wget -O
/etc/yum
.repos.d
/CentOS7-Base-163
.repo http:
//mirrors
.163.com/.help
/CentOS7-Base-163
.repo
2. cat /etc/redhat-release //查看系統的版本

3.下載對應的YUM源

4.清除緩存
yum clean all
yum makecache
yum list
四、修改yum源的優先級
1.查看系統是否安裝了優先級的插件
rpm -qa | grep yum-plugin-

2.用search查看是否有此插件可用(yum search yum-plugin-priorities),如果沒有就安裝yum-plugin-priorities.noarch插件

3.查看插件是否啟用
cat /etc/yum/pluginconf.d/priorities.conf
4.修改本地yum源優先使用
vi /etc/yum.repos.d/local.repo
priority=1
//
在原基礎上加入priority=1 ;數字越小優先級越高
//
可以繼續修改其他源的priority值,經測試僅配置本地源的優先級為priority=1就會優先使用本地源了
