<p>
在Linux中有哪些控制进程的命令呢，我们来看看先～</p>
<p>
<strong>操作系统：</strong>Debian8.5</p>
<p>
<span><strong>注意：</strong></span>下述中的n，代表的是jobs中的序号</p>
<p>
1、查看Linux中有哪些在后台运行的进行命令：<code>jobs</code></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_225680">
<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>
<div class="line number2 index1 alt1">
2</div>
<div class="line number3 index2 alt2">
3</div>
<div class="line number4 index3 alt1">
4</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain">root@wing-01:~ </code><code class="bash comments"># jobs</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash plain">+ Stopped     python backup_mysql.py wing 1.2.3.4 8888 wing</code>
</div>
<div class="line number3 index2 alt2">
<code class="bash plain">- Running     python backup_mysql.py wing 1.2.3.5 8888 wing &</code>
</div>
<div class="line number4 index3 alt1">
<code class="bash plain">root@wing-01:~ </code><code class="bash comments">#</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
2、让进程后台运行：<code>cmd &</code></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_487313">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">

</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
3、让后台进程n到前台运行: <code>fg %n</code></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_9912">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">

</div>
<div class="line number3 index2 alt2">
<code class="bash plain">- Running     python backup_mysql.py wing 1.2.3.5 8888 wing &</code>
</div>
<div class="line number4 index3 alt1">
<code class="bash plain">root@wing-01:~ </code><code class="bash comments"># fg %2</code>
</div>
<div class="line number5 index4 alt2">
<code class="bash plain">python backup_mysql.py wing 1.2.3.5 8888 wing</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
4、让前台n到后台运行：<code>bg %n</code></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_748457">
<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>
<div class="line number2 index1 alt1">
2</div>
<div class="line number3 index2 alt2">
3</div>
<div class="line number4 index3 alt1">
4</div>
<div class="line number5 index4 alt2">
5</div>
<div class="line number6 index5 alt1">
6</div>
<div class="line number7 index6 alt2">
7</div>
<div class="line number8 index7 alt1">
8</div>
<div class="line number9 index8 alt2">
9</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash comments"># 该命令适用于通过ctrl-z暂停的进程</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash comments"># 如下面job中的job1是通过ctrl-z暂停的，该程序将不在占用CPU，暂停执行，可以通过top查看其占用CPU率为0%，此时不仅可以通过fg %n让其前台继续运行，也可以通过bg %n让其后台继续运行</code>
</div>
<div class="line number3 index2 alt2">
<code class="bash plain">root@wing-01:~ </code><code class="bash comments"># jobs</code>
</div>
<div class="line number4 index3 alt1">
<code class="bash plain">+ Stopped     python backup_mysql.py wing 1.2.3.4 8888 wing</code>
</div>
<div class="line number5 index4 alt2">

<code class="bash plain">root@wing-01:~ </code><code class="bash comments">#</code>
</div>
<div class="line number9 index8 alt2">
<code class="bash comments"># 此时再通过top,发现它开始占用CPU,CPU使用率不在为0，说明其已经在后台运行了。</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
5、暂停当前程序运行：<code>ctrl-z</code></p>
<p>
此时程序是处于不适用CPU执行任何任务状态，即程序是暂停的状态，等待使用其他命令将其唤醒.</p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_883146">
<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>
<div class="line number2 index1 alt1">
2</div>
<div class="line number3 index2 alt2">
3</div>
<div class="line number4 index3 alt1">
4</div>
</td>
<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain">root@wing-01:~ </code><code class="bash comments"># python backup_mysql.py yumin 172.16.33.227 3333 yumin platform test</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash plain">^Z</code>
</div>
<div class="line number3 index2 alt2">

</div>
<div class="line number4 index3 alt1">
<code class="bash plain">root@wing-01:~ </code><code class="bash comments">#</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
6、通过PID将程序暂停：<code>kill -STOP pid</code></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_204664">
<div class="toolbar">
<span>?</span>
</div>
<table border="0" cellpadding="0" cellspacing="0"><tbody><tr>
<td class="gutter">
<div class="line number1 index0 alt2">

<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain">root@wing-01:~ </code><code class="bash comments"># kill -STOP 28021</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash plain">+ Stopped     python backup_mysql.py yumin 172.16.33.227 3333 yumin</code>
</div>
<div class="line number3 index2 alt2">
<code class="bash plain">root@wing-01:~ </code><code class="bash comments"># </code>
</div>
<div class="line number4 index3 alt1">
<code class="bash comments"># 此时可以通过top查看其占用CPU率为0%，即进程已经停止。</code>
</div>
</div>
</td>
</tr></tbody></table>
</div>
</div>
<div class="codetool" id="codetool">
<div class="code_n">
<textarea></textarea>
</div>
</div>
</div>
<p>
7、通过PID将程序恢复到后台运行：<code>kill -CONT pid</code></p>
<div class="jb51code">
<div>
<div class="syntaxhighlighterbash" id="highlighter_389274">
<div class="toolbar">
<span>?</span>

<td class="code">
<div class="container">
<div class="line number1 index0 alt2">
<code class="bash plain">root@wing-01:~ </code><code class="bash comments"># kill -CONT 28021</code>
</div>
<div class="line number2 index1 alt1">
<code class="bash plain">root@wing-01:~ </code><code class="bash comments">#</code>
</div>
<div class="line number3 index2 alt2">
<code class="bash comments"># 此时再通过top,发现它开始占用CPU,CPU使用率不在为0，说明其已经在后台运行了。</code>
</div>
</div>
</td>
