1、配置163或者阿里云yum源：
阿里云yum源地址：https://mirrors.aliyun.com/centos/6.9/os/x86_64/Packages/
阿里云给出的解决办法：https://mirrors.aliyun.com/centos 点击centos后面的帮助即可看到：
1、备份 mv /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.backup 2、下载新的CentOS-Base.repo 到/etc/yum.repos.d/ CentOS 5 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo 或者 curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-5.repo CentOS 6 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo 可以直接通过访问url下载到本地后上传到linux目录中，如果linux中不支持wget时，可以使用这种方法。 或者 curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-6.repo CentOS 7 wget -O /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo 或者 curl -o /etc/yum.repos.d/CentOS-Base.repo http://mirrors.aliyun.com/repo/Centos-7.repo 3、之后运行yum makecache生成缓存
具体操作：
[[email protected] zyj]# cd /etc/yum.repos.d/ //yum源的配置文件，查看默认yum源，一般默认为centos官网下的yum源。
[[email protected] yum.repos.d]# ll

2、构建本地设置yum源：通过光盘方式。
1、插入完整版的IOS文件到光驱；将虚拟中mini版的linux虚拟机通过设置中的CD选择为完整版的镜像；
2、挂载光盘；mount /dev/cdrom /mnt
[[email protected] ~]# cd /mnt/ //查看挂载点目录 [[email protected] mnt]# ls [[email protected] mnt]# mount /dev/cdrom /mnt //挂载光盘 mount: block device /dev/sr0 is write-protected, mounting read-only [[email protected] mnt]# cd /dev [[email protected] dev]# ls -l cdrom lrwxrwxrwx. 1 root root 3 4月 30 18:52 cdrom -> sr0 [[email protected] dev]# [[email protected] dev]# cd /mnt/ //查看挂载文件 [[email protected] mnt]# ls CentOS_BuildTag GPL Packages RPM-GPG-KEY-CentOS-6 RPM-GPG-KEY-CentOS-Testing-6 EFI images RELEASE-NOTES-en-US.html RPM-GPG-KEY-CentOS-Debug-6 TRANS.TBL EULA isolinux repodata RPM-GPG-KEY-CentOS-Security-6 [[email protected] mnt]# cd Packages/ //查看挂载后的rpm文件 [[email protected] Packages]# ls 389-ds-base-1.2.11.15-89.el6.x86_64.rpm libreoffice-math-4.3.7.2-2.el6.x86_64.rpm 389-ds-base-libs-1.2.11.15-89.el6.x86_64.rpm libreoffice-ogltrans-4.3.7.2-2.el6.x86_64.rpm abrt-2.0.8-43.el6.centos.x86_64.rpm libreoffice-opensymbol-fonts-4.3.7.2-2.el6.noarch.rpm abrt-addon-ccpp-2.0.8-43.el6.centos.x86_64.rpm libreoffice-pdfimport-4.3.7.2-2.el6.x86_64.rpm abrt-addon-kerneloops-2.0.8-43.el6.centos.x86_64.rpm libreoffice-pyuno-4.3.7.2-2.el6.x86_64.rpm abrt-addon-python-2.0.8-43.el6.centos.x86_64.rpm libreoffice-ure-4.3.7.2-2.el6.x86_64.rpm abrt-cli-2.0.8-43.el6.centos.x86_64.rpm libreoffice-wiki-publisher-4.3.7.2-2.el6.x86_64.rpm abrt-desktop-2.0.8-43.el6.centos.x86_64.rpm libreoffice-writer-4.3.7.2-2.el6.x86_64.rpm abrt-gui-2.0.8-43.el6.centos.x86_64.rpm libreoffice-xsltfilter-4.3.7.2-2.el6.x86_64.rpm abrt-libs-2.0.8-43.el6.centos.x86_64.rpm libreport-2.0.9-33.el6.centos.x86_64.rpm abrt-python-2.0.8-43.el6.centos.x86_64.rpm libreport-cli-2.0.9-33.el6.centos.x86_64.rpm abrt-tui-2.0.8-43.el6.centos.x86_64.rpm libreport-compat-2.0.9-33.el6.centos.x86_64.rpm abyssinica-fonts-1.0-5.1.el6.noarch.rpm libreport-filesystem-2.0.9-33.el6.centos.x86_64.rpm acl-2.2.49-7.el6.x86_64.rpm libreport-gtk-2.0.9-33.el6.centos.x86_64.rpm acpid-1.0.10-3.el6.x86_64.rpm libreport-newt-2.0.9-33.el6.centos.x86_64.rpm adcli-0.8.1-1.el6.x86_64.rpm libreport-plugin-kerneloops-2.0.9-33.el6.centos.x86_64.rpm aic94xx-firmware-30-2.el6.noarch.rpm libreport-plugin-logger-2.0.9-33.el6.centos.x86_64.rpm aide-0.14-11.el6.x86_64.rpm libreport-plugin-mailx-2.0.9-33.el6.centos.x86_64.rpm akonadi-1.2.1-3.el6.x86_64.rpm libreport-plugin-reportuploader-2.0.9-33.el6.centos.x86_64.rpm alacarte-0.12.4-1.el6.noarch.rpm libreport-plugin-rhtsupport-2.0.9-33.el6.centos.x86_64.rpm alsa-lib-1.1.0-4.el6.x86_64.rpm libreport-plugin-ureport-2.0.9-33.el6.centos.x86_64.rpm alsa-lib-devel-1.1.0-4.el6.x86_64.rpm libreport-python-2.0.9-33.el6.centos.x86_64.rpm alsa-plugins-pulseaudio-1.1.0-1.el6.x86_64.rpm librepository-1.0.0-2.OOo31.1.el6.x86_64.rpm alsa-utils-1.1.0-10.el6.x86_64.rpm libreswan-3.15-7.3.el6.x86_64.rpm
3、修改/etc/yum.repos.d/CentOS-Base.repo；
4、该目录下的其他配置文件删除，清除缓存文件并生成缓存；
5、yum源配置完成后，可使用yum install 安装应用程序。

注意：使用挂载光盘中的rpm文件作为yum源，由于光盘不能写以及重启后可能需要重新挂载，这时候可以通过将网络上的所有rpm文件下载到本地目录中，如/opt文件中即可。
[[email protected] ~]# cp /mnt/ /opt/ cp: 略过目录"/mnt/"
3、构建本地设置yum源：通过下载rpm文件到本地目录的方式。
1、下载网络上yum源中的rpm文件到本地目录中；下载完成后通过crt自带的文件传输功能上传到linux对应的目录中；具体不在这里示范；
[[email protected] ~]# mkdir mirrors [[email protected] ~]# cd mirrors/ [[email protected] mirrors]# mkdir base [[email protected] mirrors]# ls base
安装yum-utils工具后，可以提供reposync命令。
[[email protected] ~]# yum search yum-util //忘记名字时，可以通过search查寻下； 已加载插件：fastestmirror Loading mirror speeds from cached hostfile * extras: mirrors.aliyun.com * updates: mirrors.sohu.com ====================================================== N/S Matched: yum-util ====================================================== yum-utils.noarch : Utilities based around the yum package manager Name and summary matches only, use "search all" for everything.

2、修改/etc/yum.repos.d/CentOS-Base.repo；
3、该目录下的其他配置文件删除，清除缓存文件并生成缓存；
4、yum源配置完成后，可使用yum install 安装应用程序。
Linux下设置目录网络共享
服务器端配置：
1、安装nfs-utils和rpcbind yum install -y nfs-utils rpcbind 2、设置开机启动服务 Chkconfig nfs on Chkconfig rpcbind on 3、启动相关服务 Service rpcbind start Service nfs start 4、创建共享目录 Mkdir /share 5、编辑/etc/exports文件添加如下内容： Vim /etc/exports /share client_ip(rv,no_root_squash,no_subtree_check)
客户端的指定方式：
指定ip地址的主机：192.168.0.100 指定子网中的所有主机：192.168.0.0/24或192.168.0.0/255.255.255.0 指定域名的主机：nfs.test.com 指定域中的所有主机：*.test.com 所有主机：*
