【已解决】升级CentOS中的supervisor到最新版本
期间，由于在CentOS中，卸载了旧的用yum安装的supervisor后，
其中：yum安装的supervisor自带支持systemctl控制，且配置文件在/etc/下面
使得需要去手动添加配置文件，以实现，支持systemctl去管理supervisor，包括设置开机启动
去看看如何用systemctl去管理
centos systemctl manage supervisor
centos systemctl manager supervisor
解释的很清楚
supervisor-systemd/supervisord.service at master · zokeber/supervisor-systemd
里面有个：
/usr/bin/supervisord -n
去看了看-n是nodaemon：
<code>[root@xx-general-01 robotDemo]# /usr/bin/supervisord --help supervisord -- run a set of applications as daemons. Usage: /usr/bin/supervisord [options] Options: -c/--configuration FILENAME -- configuration file -n/--nodaemon -- run in the foreground (same as 'nodaemon true' in config file) </code>
supervisor-systemd/example-nodejs.conf.bak at master · zokeber/supervisor-systemd
好像是：
其中program部分都可以自己定义environment？
supervisor-systemd/supervisord.conf at master · zokeber/supervisor-systemd
install and configure supervisord on centos 7.
提到了：
systemctl start supervisord
之前要：
systemctl daemon-reload
此处没有给/bin/supervisord加上-n，是一般正常做法

然后去：
这是前面就看到的配置：
initscripts/centos-systemd-etcs at master · Supervisor/initscripts
另外，参考：

<code>curl https://raw.githubusercontent.com/Supervisor/initscripts/master/redhat-init-mingalevme > /etc/rc.d/init.d/supervisord </code>

https://gist.github.com/danmackinlay/176149
“an init.d script for supervisord”
大概知道了：
对于保存配置到：
/etc/rc.d/init.d/supervisord
中的，是为了支持：
serverice去管理supervisor的
而此处暂时不用去考虑，只考虑用systemctl去管理supervisor即可。
继续参考：
https://github.com/zokeber/supervisor-systemd
https://gist.github.com/mozillazg/6cbdcccbf46fe96a4edd
去试试
其中：
https://github.com/Supervisor/initscripts
-》
https://github.com/Supervisor/initscripts/blob/master/centos-systemd-etcs
只是上述完整步骤中，相对最核心的supervisord.service的配置而已
而虽然
https://github.com/zokeber/supervisor-systemd
写的很完整，但是配置文件的路径写的是：
/etc/supervisor/supervisord.conf
此处打算换成自己之前用的，且文件还存在的：
/etc/supervisord.conf
（以及相关的：
/etc/supervisord.d/supervisord.conf）
现在看起来就简单了：
自己本身此处已经存在了
/etc/supervisord.conf
/etc/supervisord.d/supervisord.conf
然后只要弄个：
supervisord.service
即可。
此处先确定pip安装后，存在supervisord和supervisorctl：
<code>[root@xxx-general-01 robotDemo]# ll /usr/bin/supervisor* -rwxr-xr-x 1 root root 403 May 24 15:33 /usr/bin/supervisorctl -rwxr-xr-x 1 root root 399 May 24 15:33 /usr/bin/supervisord </code>
同时贴出之前：
【已解决】CentOS中用supervisor去管理gunicorn的Flask的app
（yum install supervisor）的supervisord.service供参考：
<code>[root@xx-general-01 robotDemo]# cat /usr/lib/systemd/system/supervisord.service [Unit] Description=Process Monitoring and Control Daemon After=rc-local.service nss-user-lookup.target [Service] Type=forking ExecStart=/usr/bin/supervisord -c /etc/supervisord.conf [Install] WantedBy=multi-user.target </code>
然后去弄个supervisord.service
<code># supervisord service for systemd (CentOS 7.0+) [Unit] Description=supervisord - Supervisor process control system for UNIX Documentation=http://supervisord.org After=network.target [Service] Type=forking # User=root ExecStart=/usr/bin/supervisord -c /etc/supervisord.conf ExecStop=/usr/bin/supervisorctl $OPTIONS shutdown ExecReload=/usr/bin/supervisorctl $OPTIONS reload KillMode=process Restart=on-failure # RestartSec=50s RestartSec=42s [Install] WantedBy=multi-user.target </code>
放到：/usr/lib/systemd/system/ 中：
<code>[root@xx-general-01 system]# pwd /usr/lib/systemd/system [root@xx-general-01 system]# cat supervisord.service # supervisord service for systemd (CentOS 7.0+) [Unit] Description=supervisord - Supervisor process control system for UNIX Documentation=http://supervisord.org After=network.target [Service] Type=forking # User=root ExecStart=/usr/bin/supervisord -c /etc/supervisord.conf ExecStop=/usr/bin/supervisorctl $OPTIONS shutdown ExecReload=/usr/bin/supervisorctl $OPTIONS reload KillMode=process Restart=on-failure # RestartSec=50s RestartSec=42s [Install] WantedBy=multi-user.target </code>
然后reload后再start，结果出错：
和：
【未解决】supervisor的conf配置中无法使用自定义变量或环境变量
【总结】
此处，想要在pip或easy_install安装supervisor
由于不是通过系统的包管理器，比如
CentOS的yum，去安装的，则默认是没有开启启动，没法通过systemctl或service去管理supervisord的，所以需要去加上这方面的配置，允许用通过systemctl或service去管理supervisord
具体做法是：
1.此处自己之前已经有了supervisor的配置
<code>[root@xx-general-01 robotDemo]# cat /etc/supervisord.conf

</code>和：

注意：
此处忽略掉environment部分，待后续解决。
然后去添加，用于systemctl控制supervisor的配置文件
<code>[root@xx-general-01 robotDemo]# cat /usr/lib/systemd/system/supervisord.service # supervisord service for systemd (CentOS 7.0+) [Unit] Description=supervisord - Supervisor process control system for UNIX Documentation=http://supervisord.org After=network.target [Service] Type=forking # User=root ExecStart=/usr/bin/supervisord -c /etc/supervisord.conf ExecStop=/usr/bin/supervisorctl $OPTIONS shutdown ExecReload=/usr/bin/supervisorctl $OPTIONS reload KillMode=process Restart=on-failure # RestartSec=50s RestartSec=42s [Install] WantedBy=multi-user.target </code>
然后记得先要reload使得配置生效：
<code>systemctl daemon-reload </code>
然后就可以正常去启动：
<code>systemctl start supervisord </code>
查看状态：
<code>systemctl status supervisord </code>
设置开机启动：
<code>systemctl enable supervisord </code>
了。
