[Supervisor] Note (Getting Started)

I haven't used it for a long time. I 'd like to talk about the installation and make a simple experiment. The system is Ubuntu14.04.

Quick configuration Installation
Sudo pip_python install supervisorsudo echo_supervisord_conf>/etc/supervisord. conf # the following error occurs: permission denied:/etc/supervisord. conf, you can use the following statement sudo su-root-c "echo_supervisord_conf>/etc/supervisord. conf"

In this way, an original configuration file is generated, but some changes need to be made

sudo vim /etc/supervisord.conf

...[unix_http_server]file=/var/run/supervisor.sock ; (the path to the socket file)...[supervisord]logfile=/var/log/supervisor/supervisord.log ; (main log file;default $CWD/supervisord.log)...[supervisorctl]serverurl=unix:///var/run/supervisor.sock ; use a unix:// URL for a unix socket...[include]files = /etc/supervisord.d/*.ini

Note that in unix_http_server and supervisorctlSockFile directory must be consistent
Then create a directory
Sudo su-root-c "mkdir-p/etc/supervisord. d"

Then, place the process management script to supervisord. d.

The following is a simple example. First, write a test script.
#!/usr/bin/python#-*- coding:utf-8 -*-#############################File Name: somejob.py#Author: orangleliu#Mail: orangleliu@gmail.com#Created Time: 2015-04-15 11:08:13#License: MIT############################import sys, timewhile True: print "pyserver runing %s"%time.ctime() sys.stdout.flush() time.sleep(10)
Configure a process management script in the/etc/supervisord. d directory.

somejob.ini

[program:somejob]command=/usr/bin/python /home/lzz/temp/super/somejob.pydirectroy=/home/lzz/temp/super/autostart=trueautorestart=truestartretries=3user=lzzstdout_logfile=/home/lzz/temp/super/%(program_name)s.logstderr_logfile=/home/lzz/temp/super/%(program_name)s.log
Operation Supervisord startup
sudo /usr/local/bin/supervisord -c /etc/supervisord.conf lzz@ubuntu:supervisord.d$ ps -ef|grep superroot 5709 1 0 11:30 ? 00:00:00 /usr/bin/python /usr/local/bin/supervisord -c /etc/supervisord.conflzz 5710 5709 0 11:30 ? 00:00:00 /usr/bin/python /home/lzz/temp/super/somejob.py

Check that my job process has been started and the log file is normal.

There is also a part of the web interface for process management, as well as boot, etc. You can view the documentation or google
