CentOS下升級系統 yum update命令 自己配置更新源
阿新 • • 發佈：2018-12-23
我在CentOS系統下用yum update命令不能更新，提示： Cannot retrieve repository metadata (repomd.xml) for repository: update. Please verify its path and try again 這個錯誤。在網上查了下需要自己配置更新源，請問如何配置?最好詳細點,附帶更新源.謝謝.

1.以root使用者進入CentOS系統。
[
2.備份repo
[[email protected] yum.repos.d]# mv CentOS-Base.repo CentOS-Base.repo.bak
3.建立新的CentOS-Base.repo檔案：（以CentOS 5.2為例）
[[email protected] yum.repos.d]#vi CentOS-Base.repo
內容如下（以中國科技大學的yum源為例）：
# CentOS-Base.repo
#
# This file uses a new mirrorlist system developed by Lance Davis for CentOS.
# 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.
