<h2>1.安装supervisor</h2>

<span class="hljs-meta">#</span><span class="bash">pip  </span>
pip install supervisor  
<span class="hljs-meta">  
#</span><span class="bash">ubuntu  </span>
sudo apt-get install supervisor  
<span class="hljs-meta">  
#</span><span class="bash">centos （可能需要先安装epel源） </span>
yum install epel-release
yum -y install supervisor  

<div data-unique="2.启动"></div>
<h2>2.启动</h2>
安装完后如supervisor没启动，可以使用如下，手动启动

<span class="hljs-meta">#</span><span class="bash">启动supervisor  </span>
/usr/bin/supervisord -c /etc/supervisord.conf  
或者
supervisord -c /etc/supervisord.conf

进入 cd /etc 目录 找到supervisord.conf 配置文件和supervisord.d 文件夹，编辑supervisord.conf文件，拉到最底部我们可以看到

files = supervisord.d/*.ini 这句代码说明它会加载supervisord.d文件夹中的所有.ini配置文件

 
<h2>3.添加开机自启动</h2>

<span class="hljs-comment">#创建supervisord.service  </span>
<span class="hljs-attribute">vi</span> /usr/lib/systemd/system/supervisord.service

激活开机启动

<span class="hljs-meta">#</span><span class="bash">激活开机启动  </span>
systemctl enable supervisord.service  
<span class="hljs-meta">  
#</span><span class="bash">如修改了supervisord.service配置文件需重新加载  </span>
systemctl daemon-reload

<h3>遇到的问题</h3>
添加要启动的程序配置文件后supervisor无法再启动，用systemctl status supervisor 命令查看状态发现有错误。

把添加的程序配置文件删除后再启动 supervisor可以正常启动，这样问题就是出现在了所添加的程序配置文件上。

比较奇怪的的是配置文件和另一台一样也会报错，需要把配置文件里面的一行命令删除后才正常。好奇怪，也不知道为什么。
