(Transferred from https://www.izixia.cn/2016/01/03/supervisor-pei-zhi-guo-cheng/)

1. Installation
pip install supervisorWhether the test was successful after installationecho_supervisord_conf

2. Create a configuration file
Create a Directory

mkdir -m 755 -p /etc/supervisor/

mkdir -m 755 conf.d

echo_supervisord_conf > /etc/supervisor/supervisord.conf

Create a configuration file in the Conf.d folder, such as App.ini

[program:pmapp]command=python3 /home/keith/temp/app.py  autorestart=true stdout_logfile=/home/keith/temp/supervisord_stdout.log stderr_logfile=/home/keith/temp/supervisord_stderr.log [supervisord]

The contents of app.py are as follows, and the function is a record every five seconds in writing:

import timedef log(): while True: with open(‘a.txt‘,‘a‘) as f: s = ‘log:%s \n‘%time.strftime(‘%H:%M:%S‘) f.write(s) print(s) time.sleep(5)log() 

3. Add a profile to the master profile

Open the/etc/supervisor/supervisord.conf file to the last line to see

;[include];files = /relative/dictory/*.ini

Delete the semicolon here, and then add our config file /etc/supervisor/conf.d/app.ini , modified as follows

[include]files = /etc/supervisor/conf.d/*.ini /etc/supervisor/example.ini  

Multiple paths are separated by spaces.

4. Start Supervisor

supervisorThere are two commands, supervisord and supervisorctl , by supervisord Managing the startup and configuration of supervisor itself, by supervisorctl managing some of the applications that use Supervisor startup and management itself, such as our app.py here

• Start Supervisor with Commands

supervisord -c /etc/supervisor/supervisord.conf  

• Close supervisor with Command

shutdown  

If the App.ini (control file) is built first, these configured programs will also start after using the start command

• Startup program app.py

start program_name  

The program name here is [Program:name] in the config file ini, so the program_name here is Pmapp

• Close the program app.py

stop program_name  

• Refresh configuration file If you modify the INI file after startup, you can refresh the reload command by using the

supervisorctl reload  

• To view the running status of a supervisor

ps -efH|grep supervisor  

Here is a reminder that if you do this, the following error occurs:

Error: .ini file does not include supervisorctl section  help, use /usr/local/bin/supervisorctl -h 

Or

error: <class ‘socket.error‘>, [Errno 101] Network is unreachable: file: /usr/lib/python2.7/socket.py line: 571 

Switch to the/etc/supervisor directory to execute the above command

Execution supervisorctl start APP_NAME or execution supervisorctl of related commands, if any

unix:///tmp/supervisor.sock no such file  

Description Supervisord Service has not started, check your supervisord.conf file final comment ; cancellation, files path no problem

[include]files = ./conf.d/*.ini  

Then rerun in the directory /etc/supervisor

supervisord -c /etc/supervisor/supervisord.conf  

Finally attach the supervisord service Run command

Reconfigure read files:supervisorctl reread

Restart Service:supervisorctl reload

To close the service:supervisorctl shutdown
