• CentOS7使用yum时File contains no section headers.解决办法


     本文转载于  https://blog.csdn.net/trokey/article/details/84908838

    安装好CenOS7后,自带的yum不能直接使用,使用会出现如下问题:



     

    原因是没有配置yum源,修改/etc/yum.repos.d/CenOS-Base.repo文件内容如下:

    # 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.
    #
    #
    
    [base]
    name=CentOS-$releasever - Base
    mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=os&infra=$infra
    #baseurl=http://mirror.centos.org/centos/$releasever/os/$basearch/
    gpgcheck=1
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
    
    #released updates 
    [updates]
    name=CentOS-$releasever - Updates
    mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=updates&infra=$infra
    #baseurl=http://mirror.centos.org/centos/$releasever/updates/$basearch/
    gpgcheck=1
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
    
    #additional packages that may be useful
    [extras]
    name=CentOS-$releasever - Extras
    mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=extras&infra=$infra
    #baseurl=http://mirror.centos.org/centos/$releasever/extras/$basearch/
    gpgcheck=1
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
    
    #additional packages that extend functionality of existing packages
    [centosplus]
    name=CentOS-$releasever - Plus
    mirrorlist=http://mirrorlist.centos.org/?release=$releasever&arch=$basearch&repo=centosplus&infra=$infra
    #baseurl=http://mirror.centos.org/centos/$releasever/centosplus/$basearch/
    gpgcheck=1
    enabled=0
    gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-CentOS-7
    
    

     编辑命令如下:

    vi /etc/yum.repos.d/CentOS-Base.repo

     保存命令

         

        按ESC键 跳到命令模式,然后:

         

        :w   保存文件但不退出vi

        :w file 将修改另外保存到file中,不退出vi

        :w!   强制保存,不推出vi

        :wq  保存文件并退出vi

        :wq! 强制保存文件,并退出vi

        q:  不保存文件,退出vi

        :q! 不保存文件,强制退出vi

        :e! 放弃所有修改,从上次保存文件开始再编辑

    或者先删除原有的文件

    rm -f  /etc/yum.repos.d/CentOS-Base.repo

    然后重新下载阿里的

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

      清理缓存

    yum clean all

    ps:如果上述方法没有解决,尝试下面:

    删除yum.repos.d目录下所有文件

    rm -f /etc/yum.repos.d/*

     然后重新下载阿里的

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

    清理缓存

    yum clean all

    测试下载安装

    yum install gcc

    结果如下:
