折腾：
【已解决】supervisor的supervisorctl start出错：unix:///var/run/supervisor/supervisor.sock no such file
期间，需要把服务器CentOS中supervisor的版本从3.1.4升级到最新版本3.3.4，或者是至少3.2.0版本之后，以便于支持environment环境变量。
其中需要注意的是：
升级后，要记得使用上现在的配置：
<code>cat /etc/supervisord.conf … </code>
[include]
;files = supervisord.d/*.ini
files = /etc/supervisord.d/*.conf
以防万一，备份现有配置：

</code>Installing — Supervisor 3.3.4 documentation
不过最好先去看，之前自己是通过什么方式安装的supervisor
之前是
<code>yum install supervisord </code>
详见：
【已解决】CentOS中用python2的pip去安装supervisor后找不到/etc/supervisor中的默认配置文件supervisord.conf
其中还：
<code>pip uninstall supervisor pip2 uninstall supervisor </code>
再去用yum安装的
原因是之前，pip安装的supervisor的配置文件，不是默认的/etc/下面的，不利于使用
（不过注意到pip安装的supervisor是最新的3.3.4的版本
并且yum安装后，自带允许systemctl去管理supervisord
后来发现：
http://supervisord.org/installing.html
也提到了这点：
“Use the package management tools of your distribution to check availability; e.g. on Ubuntu you can run apt-cache show supervisor, and on CentOS you can run yum info supervisor.
A feature of distribution packages of Supervisor is that they will usually include integration into the service management infrastructure of the distribution, e.g. allowing supervisord to automatically start when the system boots.
Distribution packages of Supervisor can lag considerably behind the official Supervisor packages released to PyPI. For example, Ubuntu 12.04 (released April 2012) offered a package based on Supervisor 3.0a8 (released January 2010).”
现在yum安装后，不是最新版本
去看看现有的：
<code>[root@xx-general-01 robotDemo]# which supervisor /usr/bin/which: no supervisor in (/root/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/root/bin) [root@xx-general-01 robotDemo]# which supervisord /usr/bin/supervisord [root@xx-general-01 robotDemo]# ll /usr/bin/supervisord -rwxr-xr-x 1 root root 318 Jul 29 2017 /usr/bin/supervisord </code>
去找找，centos yum安装，能否指定版本
centos yum install supervisor version
Installing — Supervisor 3.3.4 documentation
<code>[root@xx-general-01 robotDemo]# yum info supervisor Loaded plugins: fastestmirror Loading mirror speeds from cached hostfile * nux-dextop: mirror.li.nux.ro Installed Packages Name : supervisor Arch : noarch Version : 3.1.4 Release : 1.el7 Size : 2.2 M Repo : installed From repo : epel Summary : A System for Allowing the Control of Process State on UNIX URL : http://supervisord.org/ License : ZPLv2.1 and BSD and MIT Description : The supervisor is a client/server system that allows its users to control a : number of processes on UNIX-like operating systems. </code>
此处镜像中只有3.1.4版本的supervisor
那估计用yum安装的话，很难再指定更高的版本了

package management – How do I install Supervisor on CentOS? – Unix & Linux Stack Exchange
CentOS7下Supervisor安装与配置（Linux/Unix进程管理工具）_服务器应用_Linux公社-Linux系统门户网站
或许是：
用pip安装最新版，然后参考上面去手动加上：supervisor.service（或supervisord.service）
但是很麻烦啊
centos yum 指定版本
在CentOS系统中使用yum安装指定版本软件 – CSDN博客
<code>[root@xx-general-01 robotDemo]# yum list | grep supervisor supervisor.noarch 3.1.4-1.el7 @epel nodejs-supervisor.noarch 0.6.0-2.el7 epel </code>
只有3.1.4版本的supervisor，没有其他版本，更谈不上指定安装更高版本的了
centos yum supervisor high version
Running Supervisor — Supervisor 3.3.4 documentation
Supervisor/initscripts: User-contributed OS init scripts for Supervisor

估计是可以直接利用上面的脚步，实现开机自动启动，和用systemctl去管理supervisord的
python – How to automatically start supervisord on Linux (Ubuntu) – Server Fault
an init.d script for supervisord
此处好像是用的是sevrice管理的
所以就可以去试试：
删除旧的用yum安装的supervisor
用eash_install或pip去安装supervisor
可以确保是最新版本3.3.4.或至少是3.2.0之后的版本了
再去创建可以用systemctl管理supervisord的配置和文件
<code>[root@xx-general-01 robotDemo]# yum uninstall supervisor Loaded plugins: fastestmirror No such command: uninstall. Please use /usr/bin/yum --help [root@xx-general-01 robotDemo]# yum remove supervisor Loaded plugins: fastestmirror Resolving Dependencies --> Running transaction check ---> Package supervisor.noarch 0:3.1.4-1.el7 will be erased --> Finished Dependency Resolution Dependencies Resolved ========================================================================================================================================================================================== Package Arch Version Repository Size ========================================================================================================================================================================================== Removing: supervisor noarch 3.1.4-1.el7 @epel 2.2 M Transaction Summary ========================================================================================================================================================================================== Remove 1 Package Installed size: 2.2 M Is this ok [y/N]: y Downloading packages: Running transaction check Running transaction test Transaction test succeeded Running transaction Erasing : supervisor-3.1.4-1.el7.noarch 1/1 warning: /etc/supervisord.conf saved as /etc/supervisord.conf.rpmsave Verifying : supervisor-3.1.4-1.el7.noarch 1/1 Removed: supervisor.noarch 0:3.1.4-1.el7 Complete! [root@xx-general-01 robotDemo]# </code>
后来注意到：
此处还残留之前的配置文件的：
<code>[root@xx-general-01 robotDemo]# ll /etc/supervisord.* -rw-r--r-- 1 root root 8145 May 24 11:34 /etc/supervisord.conf.rpmsave /etc/supervisord.d: total 4 -rw-r--r-- 1 root root 2161 May 24 13:56 supervisord_server.conf </code>
然后再去安装：
【已解决】CentOS中用pip或easy_install安装supervisor
然后再去：
