linux yum源配置

以Redhta/Centos為例：

1.本地源：

#mkdir /mnt/rh7iso

#cp Packages /mnt/rh7iso

（Packages為安裝系統盤中的檔案夾）

#cd /etc/yum.repos.d/

#touch rh7iso.repo

#vim rh7iso.repo

[rh7iso]

name=rh7iso

baseurl=file:///mnt/rh7iso/

enabled=1

gpgcheck=1

gpgkey=file:///mnt/rh7iso/RPM-GPG-KEY-redhat-release

#yum clean all

#yum makecache

2.yum 網絡源：

#cd /etc

#cp profile profile_backup

#vim profile

在profile的最下面添加類似的幾行：

export http_proxy=http://proxy-prc.intel.com:911

export ftp_proxy=http://proxy-prc.intel.com:911

export HTTP_proxy=http://proxy-prc.intel.com:911

export FTP_proxy=http://proxy-prc.intel.com:911

具體以您所需網絡代理的位址，端口号相符。

#cd yum.repos.d

#rm -f *

#touch Centos-Base.repo

#vim Centos-Base.repo

以ali源為例：

# CentOS-Base.repo
#
# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client.  You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the 
# remarked out baseurl= line instead.
#

#init 6

重新開機後等大概一分鐘再進行清空yum本地源 等操作。

#yum clean all

#yum makecache

然後就可以正常用yum install安裝工具了

PS：網絡源配置重新開機能正常使用的前提是網絡端口是重新開機後能自動到擷取IP。

eg: vim /etc/sysconfig/network-scripts/ifcfg-enp2s0f0

……

……

ONBOOT=yes（開機後自動擷取IP）
