Running supervisord-c FILE | path to supervisord configuration file | -n | run supervisord in the foreground | -u USER | UNIX username or numeric user id | -l FILE | filename path to use as the supervisord activity log | -e LEVEL | Valid levels are trace, debug, info, warn, error, and critical | -j FILE | filename to which supervisord should write its pid file |
Running supervisorctl-c FILE | configuration file path | -u USER | username to use for authentication with server | -p PASSWORD | password to use for authentication with server | -r | keep a readline history |
Supervisord SignalSIGTERM | supervisord and all its subprocesses will shut down | SIGINT | supervisord and all its subprocesses will shut down | SIGQUIT | supervisord and all its subprocesses will shut down | SIGHUP | supervisord will stop all processes, reload the configuration from the first config file it finds, and start all processes | SIGUSR2 | supervisord will close and reopen the main activity log and all child log files |
Installing supervisordInstalling With Pip pip install supervisor | Install On Debian apt-get install supervisor | Install On Redhat yum install supervisor | Install On Archlinux pacman -S supervisor |
Using Environment Variables[program:example]
command=/usr/bin/example --loglevel=%(ENV_LOGLEVEL)s |
Environment variables that are present in the environment at the time that supervisord is started can be used in the configuration file using the Python string expression syntax %(ENV_X)s Using UNIX domain socket[unix_http_server]
file = /tmp/supervisor.sock
chmod = 0777
chown= nobody:nogroup
username = user
password = 123 |
HTTP server that listens on a UNIX domain socket Using process group[group:foo]
programs=bar,baz
priority=999 |
Group “homogeneous” process groups (aka “programs”) together into a “heterogeneous” process group | | Using TCP domain socket[inet_http_server]
port = 127.0.0.1:9001
username = user
password = 123 |
HTTP server that listens on a TCP (internet) socket Log Levelcritical | CRIT | error | ERRO | warn | WARN | info | INFO | debug | DEBG | trace | TRAC | blather | BLAT |

Supervisord to know which programs it should start and control Using configuration directory[include]
files = supervisord.d/*.conf |
Include configuration files from drop in directory | | Supervisorctl actionshelp | print a list of available actions | help <action> | print help for <action> | add <name> [...] | activates any updates in config for process/group | remove <name> [...] | removes process/group from active config | update | reload config and then add and remove as necessary | clear <name> | clear a process’ log files | clear <name> <name> | clear multiple process’ log files | clear all | clear all process’ log files | fg <process> | connect to a process in foreground mode Press Ctrl+C to exit foreground | pid | get the PID of supervisord | pid <name> | get the PID of a single child process by name | pid all | get the PID of every child process, one per line | reload | restarts the remote supervisord | reread | reload the daemon’s configuration files, without add/remove (no restarts) | restart <name> | restart a process | restart <gname>:* | restart all processes in a group | restart <name> <name> | restart multiple processes | restart all | restart all processes | signal | No help on signal | start <name> | start a process | start <gname>:* | start all processes in a group | start <name> <name> | start multiple processes | start all | start all processes | status | get all process status info | status <name> | get status on a single process by name | status <name> <name> | get status on multiple named processes | stop <name> | stop a process | stop <gname>:* | stop all processes in a group | stop <name> <name> | stop multiple processes or groups | stop all | stop all processes | tail [-f] <name> [stdout|stderr] | output the last part of process logs |
