ubuntu制作本地源的实现方法
<p><span><strong>背景</strong></span></p>
<p>
平时apt-get install安装软件时，下载的deb文件都会存放在/var/cache/apt/archives/下，为了今后重装或给别人用，特别是没有网络时，这些deb文件实际上是可以派上用途的，也就是可以用这些deb制作成本地源。这种方法还有一个应用场景：</p>
<p>
1.先在有网络的服务器上面进行apt-get install安装</p>
<p>
2.然后制作本地源</p>
<p>
3.将本地源拷贝到没有网络的服务器上，然后在那台机器上设定sourcelist指向这个本地源，此时在那台没有网络的服务器上也可以执行apt-get install安装了。</p>
<p>
<span><strong>下面给出可行且实用的部分本地源制作步骤：</strong></span></p>
<p>
<span><strong>一、在自己的根目录下建立一个目录，用于放所有下载的软件包，目录名随自己喜欢,建议新手在自己的根目录下进行以下操作，以避免操作权限问题的困扰。</strong></span></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterxhtml" id="highlighter_824729">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="xhtml plain">mkdir ~/ packs</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
拷贝过来发现在packs当中为文件都是root账户的，需要修改</p>
<p>
修改所有者</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterxhtml" id="highlighter_100788">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="xhtml plain">sudo chown -R enadmin.enadmin *</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
修改权限</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterxhtml" id="highlighter_734453">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="xhtml plain">sudo chmod ug+rw,o+r *</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
<span><strong>二、复制文件到packs文件夹下，目录依各人情况变化。</strong></span></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterxhtml" id="highlighter_48765">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="xhtml plain">sudo cp /var/cache/apt/archives/* ~/packs -r</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
<span><strong>三、建立Packages.gz包，里面记录了packs文件夹下面的软件包信息，包括依赖信息。</strong></span></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterxhtml" id="highlighter_248897">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="xhtml plain">dpkg-scanpackages packs /dev/null |gzip > packs/Packages.gz -r </code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
完成此操作后，将packs文件夹复制到一个不常格式化的分区中，作为长久使用，比如我将它放在一个fat32的分区时面，路径是 /media/packs</p>
<p>
<span><strong>四、加本地源</strong></span></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterxhtml" id="highlighter_15735">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="xhtml plain">sudo gedit /etc/apt/sources.list</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
添加以下内容：</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterxhtml" id="highlighter_509305">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="xhtml plain">deb file:///media/ packs/ </code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
注意packs后面有一个斜杠，前面还要有空格</p>
<p>
<span><strong>五、更新源</strong></span></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterxhtml" id="highlighter_146729">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">
1</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="xhtml plain">sudo apt-get update</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
