說明：今天在火車上測試一個CentOS7下的一個服務，要用到yum配置，但是本機沒有聯網，所以考慮到配置本地yum，按照之前CentOS6下的常規方法，居然發現有報錯。
操作如下：
1）虛擬機下將CentOS7光盤加載到系統里面，然后掛載到本地的/localyum上
[root@localhost yum.repos.d]# mount /dev/cdrom /localyum
2）添加一個repo文件
[root@localhost ~]# cd /etc/yum.repos.d/ [root@localhost yum.repos.d]# vim CentOS7-local.repo [localyum] name=localyum baseurl=file:///localyum/ gpgcheck=0 enabled=1
3）測試安裝下vsftpd軟件
[root@localhost yum.repos.d]# yum -y install vsftpd 已加載插件：fastestmirror, langpacks Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=stock error was 14: curl#6 - "Could not resolve host: mirrorlist.centos.org; 未知的錯誤" One of the configured repositories failed (未知), and yum doesn't have enough cached data to continue. At this point the only safe thing yum can do is fail. There are a few ways to work "fix" this: 1. Contact the upstream for the repository and get them to fix the problem. 2. Reconfigure the baseurl/etc. for the repository, to point to a working upstream. This is most often useful if you are using a newer distribution release than is supported by the repository (and the packages for the previous distribution release still work). 3. Disable the repository, so yum won't use it by default. Yum will then just ignore the repository until you permanently enable it again or use --enablerepo for temporary usage: yum-config-manager --disable <repoid> 4. Configure the failing repository to be skipped, if it is unavailable. Note that yum will try to contact the repo. when it runs most commands, so will have to try and fail each time (and thus. yum will be be much slower). If it is a very temporary problem though, this is often a nice compromise: yum-config-manager --save --setopt=<repoid>.skip_if_unavailable=true Cannot find a valid baseurl for repo: base/7/x86_64
4）由于是在局域網內，無法正常連上外網，所有重新調整了下repo文件
[root@localhost yum.repos.d]# vim CentOS7-local.repo [localyum] name=localyum baseurl=file:///localyum/ gpgcheck=0 enabled=1 yum --disablerepo=\* --enablerepo=localyum clean all#清除緩存 yum --disablerepo=\* --enablerepo=localyum makecache#緩存本地yum源包信息
5）重新安裝下vsftpd軟件
[root@localhost yum.repos.d]# yum -y install vsftpd 已加載插件：fastestmirror, langpacks base | 3.6 kB 00:00:00 extras | 3.4 kB 00:00:00 localyum | 3.6 kB 00:00:00 updates | 3.4 kB 00:00:00 (1/6): localyum/group_gz | 154 kB 00:00:00 (2/6): localyum/primary_db | 2.7 MB 00:00:00 (3/6): extras/7/x86_64/primary_db | 149 kB 00:00:00 (4/6): updates/7/x86_64/primary_db | 5.7 MB 00:00:18 (5/6): base/7/x86_64/group_gz | 155 kB 00:00:21 (6/6): base/7/x86_64/primary_db | 5.3 MB 00:00:29 Determining fastest mirrors * base: mirrors.163.com * extras: mirrors.cqu.edu.cn * updates: mirrors.cqu.edu.cn 正在解決依賴關系 --> 正在檢查事務 ---> 軟件包 vsftpd.x86_64.0.3.0.2-11.el7_2 將被 安裝 --> 解決依賴關系完成 依賴關系解決 ==================================================================================================================================================== Package 架構 版本 源 大小 ==================================================================================================================================================== 正在安裝: vsftpd x86_64 3.0.2-11.el7_2 updates 167 k 事務概要 ==================================================================================================================================================== 安裝 1 軟件包 總下載量：167 k 安裝大?。?47 k Downloading packages: vsftpd-3.0.2-11.el7_2.x86_64.rpm | 167 kB 00:00:00 Running transaction check Running transaction test Transaction test succeeded Running transaction 正在安裝 : vsftpd-3.0.2-11.el7_2.x86_64 1/1 驗證中 : vsftpd-3.0.2-11.el7_2.x86_64 1/1 已安裝: vsftpd.x86_64 0:3.0.2-11.el7_2 完畢！
6）配置光盤開機自動掛載
[root@localhost ~]# echo "/dev/cdrom /localyum iso9660 defaults 0 0">>/etc/fstab [root@localhost ~]# mount -a
