<p>Supervisor（<a href="http://supervisord.org/" rel="nofollow" data-token="9a63bf72d5d1340e40ad98701bd2911a">http://supervisord.org/</a>）是用Python开发的一个client/server服务，是Linux/Unix系统下的一个进程管理工具，不支持Windows系统。它可以很方便地监听、启动、停止、重启一个或<strong>多个</strong>进程。当一个进程意外终止时，supervisort监听到进程死亡，会自动将它重新启动，很方便地做到用户进程守护的功能，不需要自己再写shell脚本来控制。</p>

<p>由于Supervisor是用Python开发的程序，在安装前，请确保系统已安装Python，并确保python版本至少为2.4。下面在CentOS7操作系统和Python2.7版本环境下，介绍Supervisor的安装与配置步聚：</p>

<h2 id="1安装python包管理工具easyinstall"><a name="t0"></a>1、安装Python包管理工具easy_install</h2>

<p>easy_install是setuptools包里带的一个命令。使用easy_install，实际上是在调用setuptools来完成模块的安装工作。</p>

<p>设置PYTHONPATH，在.bash_profile里添加如下内容：</p>

<pre class="has" name="code"><code class="hljs bash"><span class="hljs-built_in">export</span> PYTHONPATH=<span class="hljs-variable">$HOME</span>/Python
</code><div class="hljs-button signin" data-title="登录后复制" onclick="hljs.signin(event)"></div></pre>

<p>注意：如果$HOME/Python目录不存在，请使用如下命令创建：</p>

<pre class="has" name="code"><code class="hljs perl">$ <span class="hljs-keyword">mkdir</span> $HOME/Python</code><div class="hljs-button signin" data-title="登录后复制" onclick="hljs.signin(event)"></div></pre>

<p>转到$HOME/Python目录，下载setuptools包：</p>

<pre class="has" name="code"><code class="hljs ruby"><ol class="hljs-ln"><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="1"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line">$ cd $HOME/Python</div></div></li><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="2"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line">$ wget --no-check-certificate <span class="hljs-symbol">https:</span>/<span class="hljs-regexp">/bootstrap.pypa.io/ez</span>_setup.py -O - <span class="hljs-params">| sudo python</span></div></div></li></ol></code><div class="hljs-button signin" data-title="登录后复制" onclick="hljs.signin(event)"></div></pre>

<h2 id="2安装supervisor"><a name="t1"></a>2、安装supervisor</h2>

<p>在第1步中，获取到的setuptools包为setuptools-33.1.1.zip，对其进行解压缩，使用easy_install工具安装supervisor：</p>

<pre class="has" name="code"><code class="hljs ruby"><ol class="hljs-ln"><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="1"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line">$ unzip setuptools-<span class="hljs-number">33.1</span>.<span class="hljs-number">1</span>.zip</div></div></li><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="2"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line">$ cd setuptools-<span class="hljs-number">33.1</span>.<span class="hljs-number">1</span></div></div></li><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="3"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line">$ easy_install --install-dir=$HOME/Python supervisor</div></div></li></ol></code><div class="hljs-button signin" data-title="登录后复制" onclick="hljs.signin(event)"></div></pre>

<p>supervisor安装完成后，会生成<span style="color:#3399ea;">三个执行程序：supervisortd、supervisorctl、echo_supervisord_conf</span>，分别是<span style="color:#86ca5e;">supervisor的守护进程服务（用于接收进程管理命令）、客户端（用于和守护进程通信，发送管理进程的指令）、生成初始配置文件程序</span>。</p>

<p>运行supervisord服务的时候，需要指定supervisor配置文件。如果没有显示指定，则默认在以下目录查找：</p>

<pre class="has" name="code"><code class="hljs vbscript"><ol class="hljs-ln"><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="1"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line">$CWD/supervisord.conf</div></div></li><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="2"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line">$CWD/etc/supervisord.conf</div></div></li><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="3"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line">/etc/supervisord.conf</div></div></li><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="4"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line">/etc/supervisor/supervisord.conf (since Supervisor <span class="hljs-number">3.3</span><span class="hljs-number">.0</span>)</div></div></li><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="5"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line">../etc/supervisord.conf (Relative <span class="hljs-keyword">to</span> the executable)</div></div></li><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="6"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line">../supervisord.conf (Relative <span class="hljs-keyword">to</span> the executable)</div></div></li></ol></code><div class="hljs-button signin" data-title="登录后复制" onclick="hljs.signin(event)"></div></pre>

<p>其中，$CWD表示“运行supervisord程序的目录”。</p>

<p>通过运行echo_supervisord_conf程序，可以生成supervisor的初始化配置文件，如下所示：</p>

<p>supervisor的配置参数较多，下面介绍一下常用的参数配置，详细的配置及说明，请参考<a href="http://supervisord.org/configuration.html" rel="nofollow" data-token="3c0abe008dc93eff0efd9e8847362e45">官网文档</a>介绍。 <br>

<p>注意：对于include示例，在使用相对路径时，默认当前目录为supervisord.conf所在目录。</p>

<h2 id="5配置管理进程"><a name="t4"></a>5、配置管理进程</h2>

<p>进程管理配置参数，不建议全都写在supervisord.conf文件中，建议每个进程写一个配置文件，并放在include配置块中files指定的目录下，通过include包含进supervisord.conf文件中。 <br>
1. 创建$HOME/Python/etc/supervisord.d目录，用于存放“进程管理配置文件”。<br>
2. 修改$HOME/Python/etc/supervisord.conf中的include参数，将$HOME/Python/etc/supervisord.d目录添加到include中。</p>

<p>下面是配置Tomcat进程的一个例子：</p>

<h2 id="5启动supervisor服务"><a name="t5"></a>5、启动Supervisor服务</h2>

<h2 id="6控制进程"><a name="t6"></a>6、管理用户进程</h2>

<p>supervisord启动成功后，通过supervisorctl客户端来管理用户进程：启动、停止、重启。运行supervisorctl命令，会进入supervisor客户端的交互终端，并会列出当前所管理的所有进程。 </p>

<pre class="has" name="code"><code class="hljs swift">$ /usr/bin/python supervisorctl -<span class="hljs-built_in">c</span> etc/supervisord.conf</code><div class="hljs-button signin" data-title="登录后复制" onclick="hljs.signin(event)"></div></pre>

<p>上图中的tomcat就是我们在配置文件中[program:tomcat]指定的名字。</p>

<p>输入help，可以查看命令列表。如果想看某个命令的作用，运行“help 命令名称”，如：help stop。stop tomcat 表示停止tomcat进程， stop all 表示停止所有进程。</p>

<p>修改文件权限为755，并设置开机启动：</p>

<p>注意：修改脚本中supervisor配置文件路径为你的supervisor的配置文件路径</p>

<p><strong>其它Linux发行版开机启动脚本</strong>：<a href="https://github.com/Supervisor/initscripts" rel="nofollow" data-token="61e6eaec9d202eb6f2db8b659a91d7f2">https://github.com/Supervisor/initscripts</a></p>

<p><strong>注意：Supervisor只能管理非daemon的进程，不能管理守护进程。</strong>否则，会提示Exited too quickly (process log may have details)异常。例子中的Tomcat默认是以守护进程启动的，所以我们改成了catalina.sh run，以前台进程的方式运行。</p>

<p>另附：在centos操作系统上，以yum方式安装，使用如下命令。</p>

<pre class="has" name="code"><code class="hljs sql"><ol class="hljs-ln"><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="1"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line">$ yum <span class="hljs-keyword">install</span> epel-<span class="hljs-keyword">release</span></div></div></li><li><div class="hljs-ln-numbers"><div class="hljs-ln-line hljs-ln-n" data-line-number="2"></div></div><div class="hljs-ln-code"><div class="hljs-ln-line">$ yum <span class="hljs-keyword">install</span> -y supervisor</div></div></li></ol></code><div class="hljs-button signin" data-title="登录后复制" onclick="hljs.signin(event)"></div></pre>

<p>supervisor没有发布在标准的CentOS源上，需要安装epel源。这种方式安装的supervisor可能不是最新版本，但比较方便，安装完成之后，配置文件会自动帮你生成。 <br>
默认配置文件：/etc/supervisord.conf <br>
进程管理配置文件放到：/etc/supervisord.d/目录下即可。</p> </div>
