docker容器中安装vim
<p>在使用docker容器时，有时候里边没有安装vim，敲vim命令时提示说：vim: command not found，这个时候就需要安装vim，可是当你敲apt-get install vim命令时，提示：</p><p> </p>
<div class="cnblogs_code">
<pre>Reading <span style="color: rgba(0, 0, 255, 1)">package</span><span style="color: rgba(0, 0, 0, 1)"> lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate </span><span style="color: rgba(0, 0, 255, 1)">package</span> vim</pre>
</div>
<p> </p>
<p> 这时候需要敲：apt-get update，这个命令的作用是：同步 /etc/apt/sources.list 和 /etc/apt/sources.list.d 中列出的源的索引，这样才能获取到最新的软件包。</p>
<p> 等更新完毕以后再敲命令：apt-get install vim命令即可。</p>
<h3 id="配置国内镜像源">配置国内镜像源</h3>
<p>实际在使用过程中，运行 apt-get update，然后执行 apt-get install -y vim，下载地址由于是海外地址，下载速度异常慢而且可能中断更新流程，所以做下面配置：</p>
<div class="cnblogs_code">
<pre>mv /etc/apt/sources.list /etc/apt/<span style="color: rgba(0, 0, 0, 1)">sources.list.bak
echo </span>"deb http://mirrors.163.com/debian/ jessie main non-free contrib" >> /etc/apt/<span style="color: rgba(0, 0, 0, 1)">sources.list
echo </span>"deb http://mirrors.163.com/debian/ jessie-proposed-updates main non-free contrib" >>/etc/apt/<span style="color: rgba(0, 0, 0, 1)">sources.list
echo </span>"deb-src http://mirrors.163.com/debian/ jessie main non-free contrib" >>/etc/apt/<span style="color: rgba(0, 0, 0, 1)">sources.list
echo </span>"deb-src http://mirrors.163.com/debian/ jessie-proposed-updates main non-free contrib" >>/etc/apt/<span style="color: rgba(0, 0, 0, 1)">sources.list
#更新安装源
apt</span>-get update </pre>
</div>
