  Supervisor（http://supervisord.org/）是用Python开发的一个client/server服务，是Linux/Unix系统下的一个进程管理工具，不支持Windows系统。它可以很方便的监听、启动、停止、重启一个或多个进程。用Supervisor管理的进程，当一个进程意外被杀死，supervisort监听到进程死后，会自动将它重新拉起，很方便的做到进程自动恢复的功能，不再需要自己写shell脚本来控制

 sudo yum install epel-release -y

 yum install rsync  # 有d的 这个不对 supervisord

一些常用配置

minprocs=200                 ;可以打开的进程数的最小值，默认 200

常用命令

#只重启特定的任务 
supervisorctl restart chat-im-message: client-user-connection: room-statistic-event: robot-comment:  robot-praise:

#stop

autostart=true
autorestart=true

killasgroup=true


bash终端

supervisorctl reload
supervisorctl status
supervisorctl stop tomcat
supervisorctl start tomcat
supervisorctl restart tomcat
supervisorctl reread
supervisorctl update

查看单个任务状态: supervisorctl status　服务名

开机启动Supervisor服务
7.1 配置systemctl服务

1> 进入/lib/systemd/system目录，并创建supervisor.service文件

[Unit]
Description=supervisor
After=network.target

[Service]
Type=forking
ExecStart=/usr/bin/supervisord -c /etc/supervisor/supervisord.conf
ExecStop=/usr/bin/supervisorctl $OPTIONS shutdown
ExecReload=/usr/bin/supervisorctl $OPTIONS reload
KillMode=process
Restart=on-failure
RestartSec=42s

[Install]
WantedBy=multi-user.target

2> 设置开机启动

systemctl enable supervisor.service
systemctl daemon-reload

3、修改文件权限为766

chmod 766 supervisor.service

trouble shooting

记得要  supervisorctl reload
求助！supervisord 报错 FATAL Exited too quickly (process log may have details)

entered FATAL state, too many start retries too quickly

我 user 改成 root 之后可以了


supervisor 比较适合监控业务应用，且只能监控前台程序，php fork方式实现的daemon不能用它监控，否则supervisor> status 会提示：BACKOFF Exited too quickly (process log may have details) 



# supervisorctl restart handle-user-question:
