  ; The supervisorctl section configures how supervisorctl will connect to

  [supervisorctl]

• 管理的应用-配置

  • 单进程模板

    [program:command-example]
    command=command example.sh
    autostart=true
    autorestart=true
    startretries=3
    
    ; stop
    stopsignal=TERM
    
    ; user
    user=www
    
    ; 日志
    redirect_stderr=true
    stdout_logfile=/data/log/supervisord/%(program_name)s.log
    stdout_logfile_maxbytes=1MB
    stdout_logfile_backups=50
    

  • 多进程模板

    [program:command-example2]
    command=command example2.sh
