安裝好CenOS7后,自帶的yum不能直接使用,使用會出現如下問題:

已加載插件:fastestmirror, langpacks File contains no section headers. file: file:///etc/yum.repos.d/convirt.repo, line: 1 "<html><head><title>Loading...</title></head><body><script type='text/javascript'>window.location.replace('http://www.convirture.c


原因是沒有配置yum源,修改/etc/yum.repos.d/CenOS-Base.repo文件內容如下:

# 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.
#

如果不行,這樣,刪除原有的文件:

rm -f /etc/yum.repos.d/CentOS-Base.repo
然后重新下載阿里的:

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
 清理緩存:

yum clean all
ps:如果上述方法沒有解決,嘗試下面:

刪除yum.repos.d目錄下所有文件

rm -f /etc/yum.repos.d/*
 然后重新下載阿里的:

wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo
清理緩存:

yum clean all
測試下載安裝:

yum install gcc
完成!
