Docker安装yum，vim
1.没有yum命令
添加国内镜像
mv /etc/apt/sources.list /etc/apt/sources.list.bak
echo "deb http://mirrors.163.com/debian/ jessie main non-free contrib" >> /etc/apt/sources.list
echo "deb http://mirrors.163.com/debian/ jessie-proposed-updates main non-free contrib" >>/etc/apt/sources.list
echo "deb-src http://mirrors.163.com/debian/ jessie main non-free contrib" >>/etc/apt/sources.list
echo "deb-src http://mirrors.163.com/debian/ jessie-proposed-updates main non-free contrib" >>/etc/apt/sources.list更新apt-get指令
apt-get update安装yum命令
apt-get install yum安装vim命令
apt-get install vim添加ls命令
vim ~/.bashrc在最后一行添加
alias ll='ls $LS_OPTIONS -l'使之生效
source ~/.bashrc安装ping指令为 apt-get install iputils-ping； 安装ifconfig指令为 apt-get install net-tools， 以此类推，安装你需要的工具。
安装完yum不能运行
root@3c7c47822bf0:/var/plugin# yum -y install fontconfig libX11 libXext libXrender libjpeg openssl xorg-x11-fonts-75dpi xorg-x11-fonts-Type1 && rpm -ivh wkhtmltox-0.12.5-1.centos7.x86_64.rpm
There are no enabled repos.
Run "yum repolist all" to see the repos you have.
You can enable repos with yum-config-manager --enable 解决办法：
运行
yum repolist all结果
root@3c7c47822bf0:/var/plugin# yum repolist all
repolist: 0运行
yum -y install yum-utils不能运行yum -y install yum-utils,返回以下错误
root@3c7c47822bf0:/var/plugin# yum -y install yum-utils

/etc/yum/repos.d/执行ls /etc/yum/repos.d/命令查看, /etc/yum/repos.d/目录下为空
如果yum -y install yum-utils不能运行先试着更换yum源：
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执行ls /etc/yum/repos.d/命令查看,CentOS-Base.repo下载完成
root@3c7c47822bf0:/var/plugin# ls /etc/yum/repos.d/
CentOS-Base.repo运行命令生成缓存
yum clean all
yum makecache执行yum makecache出现以下错误:
root@3c7c47822bf0:/var/plugin# yum makecache
