Supervisor是一款后臺(tái)進(jìn)程管理工具靠欢，保障不被異常終端题翰，有重啟等功能
安裝
pip install supervisor
配置文件
通過(guò)pip安裝的默認(rèn)是沒(méi)有配置文件，需要進(jìn)行創(chuàng)建
echo_supervisord_conf > /etc/supervisor.conf
;[program:theprogramname]
;command=/bin/cat ; the program (relative uses PATH, can take args)
;process_name=%(program_name)s ; process_name expr (default %(program_name)s)
;numprocs=1 ; number of processes copies to start (def 1)
;directory=/tmp ; directory to cwd to before exec (def no cwd)
;umask=022 ; umask for process (default None)
;priority=999 ; the relative start priority (default 999)
;autostart=true ; start at supervisord start (default: true)
;startsecs=1 ; # of secs prog must stay up to be running (def. 1)
;startretries=3 ; max # of serial start failures when starting (default 3)
;autorestart=unexpected ; when to restart if exited after running (def: unexpected)
;exitcodes=0,2 ; 'expected' exit codes used with autorestart (default 0,2)
;stopsignal=QUIT ; signal used to kill process (default TERM)
;stopwaitsecs=10 ; max num secs to wait b4 SIGKILL (default 10)
;stopasgroup=false ; send stop signal to the UNIX process group (default false)
;killasgroup=false ; SIGKILL the UNIX process group (def false)
;user=chrism ; setuid to this UNIX account to run the program
;redirect_stderr=true ; redirect proc stderr to stdout (default false)
;stdout_logfile=/a/path ; stdout log path, NONE for none; default AUTO
;stdout_logfile_maxbytes=1MB ; max # logfile bytes b4 rotation (default 50MB)
;stdout_logfile_backups=10 ; # of stdout logfile backups (0 means none, default 10)
;stdout_capture_maxbytes=1MB ; number of bytes in 'capturemode' (default 0)
;stdout_events_enabled=false ; emit events on stdout writes (default false)
;stderr_logfile=/a/path ; stderr log path, NONE for none; default AUTO
;stderr_logfile_maxbytes=1MB ; max # logfile bytes b4 rotation (default 50MB)
;stderr_logfile_backups=10 ; # of stderr logfile backups (0 means none, default 10)
;stderr_capture_maxbytes=1MB ; number of bytes in 'capturemode' (default 0)
;stderr_events_enabled=false ; emit events on stderr writes (default false)
;environment=A="1",B="2" ; process environment additions (def no adds)
;serverurl=AUTO ; override serverurl computation (childutils)
這里是系統(tǒng)給出的配置內(nèi)容，可以根據(jù)自己的需求去添加對(duì)應(yīng)字段
例
配置
[program:demo1]
directory=/root/test/
command=python a.py
autostart=true
autorestart=true
配置成功后在終端進(jìn)行更新
supervisorctl update
supervisorctl reload
運(yùn)行
supervisorctl -c /etc/supervisor.conf
supervisorctl> status //查看狀態(tài)
supervisorctl> start demo1 //啟動(dòng)
supervisorctl> restart demo1 //重啟
supervisorctl> stop demo1 //停止
