前言
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。
环境准备
centos 安装 supervisord
1
|
yum install -y supervisord |
debian 安装 supervisord
1
|
apt-get install -y supervisor |
supervisord.conf
安装完成后在/etc/supervisor
目录下会有个配置文件 supervisord.conf

# cd /etc/supervisor /etc/supervisor # ls conf.d supervisord.conf |

在项目中我们需要用到此配置,可以在项目根目录导出一份

echo_supervisord_conf > . /supervisord .conf |
文件内容编写
supervisord.conf文件内容编写, 前面内容不用改,直接接着在后面写
比如我需要后台启动celery的worker和beat服务

; Sample supervisor config file . ; ; For more information on the config file , please see: ; http: / / supervisord.org / configuration.html ; 前面文档省略,不用删,接着后面写 [program:celery - worker] command = celery - A hrun2_web worker - l info ; 管理命令,supervisor不支持后台进程 process_name = % (program_name)s #user=root ;进程启动用户 autostart = true ;是否随supervisor启动 autorestart = true ;是否在挂了之后重启,意外关闭后会重启,比如kill掉! startretries = 3 ;启动尝试次数 stderr_logfile = . / celery_worker.log ;标准输出文件 stdout_logfile = . / celery_worker.log ;标准输出文件 loglevel = info ;日志的级别 [program:celery - beat] command = celery - A hrun2_web beat ; 管理命令,supervisor不支持后台进程 process_name = % (program_name)s #user=root ;进程启动用户 autostart = true ;是否随supervisor启动 autorestart = true ;是否在挂了之后重启,意外关闭后会重启,比如kill掉! startretries = 3 ;启动尝试次数 stderr_logfile = . / celery_beat.log ;标准输出文件 stdout_logfile = . / celery_beat.log ;标准输出文件 loglevel = info ;日志的级别 |
启动服务
启动服务
1
|
supervisord -c /path/supervisord .conf |
关闭服务
1
|
supervisorctl shutdown |
运行过程,启动没问题,不显示任何内容,如果需要关闭用shutdown

|
root@13107c465557: /code # supervisord -c ./supervisord.conf root@13107c465557: /code # supervisorctl shutdown Shut down |
查看启动的服务
1
|
supervisorctl status |
执行结果如下
root@13107c465557:/code# supervisorctl status
celery-worker RUNNING pid 234, uptime 0:00:14
celery-beat RUNNING pid 235, uptime 0:00:14
说明启动了celery和celery-beat两个服务
查看日志
我们在配置里面指定了./celery_worker.log
文件保存运行日志,所以可以直接查看这个文件
1
|
tail -f celery_worker.log -n 30 |
运行就可以看到worker运行的日志了
