Supervisor Python进程管理工具
Supervisor 是一个客户端/服务器系统,允许用户监控和控制类 Unix 操作系统上的进程数。
本文为大家讲解的是supervisor 配置文件使用详细，感兴趣的同学参考下。
Supervisor 是一个客户端/服务器系统,允许用户监控和控制类 Unix 操作系统上的进程数。
本文不陈述配置文件中的参数，而是关于配置文件的使用，强调2点
1. 对于supervisor 而言，配置文件在不手动指定的情况下 -c 参数
$CWD/supervisord.conf
$CWD/etc/supervisord.conf
/etc/supervisord.conf
所以要小心配置文件被错误使用
2. supervisorctl 与supervisord 进程进行通讯默认使用的是 tcp 连接
[inet_http_server]
port = 127.0.0.1:9001
username = user
password = 123
但是出于安全考虑很多人使用的是unix域套接字，
[unix_http_server]
file = /tmp/supervisor.sock
chmod = 0777
chown= nobody:nogroup
username = user
password = 123
所以在使用supervisorctl 时，如果supervisorctl 无法查找到配置文件，
supervisorctl 无法获知与supervisord 该如何通讯，你可能会看到如下错误
root@xxx:/home/operation# supervisorctl status
http://localhost:9001 refused connection
3. supervisorctl 支持
(sm_env)root@xxx:/etc/supervisor# supervisorctl help
default commands (type help <topic>):
=====================================
add clear fg open quit remove restart start stop update
avail exit maintail pid reload reread shutdown status tail version
root@xxx:/etc/supervisor# supervisorctl help update
update Reload config and add/remove as necessary
参考官方文档:
The Supervisor configuration file is conventionally named supervisord.conf. It is used by bothsupervisord and supervisorctl. If either application is started without the -c option (the option which is used to tell the application the configuration filename explicitly), the application will look for a file named supervisord.conf within the following locations, in the specified order. It will use the first file it finds.
$CWD/supervisord.conf
$CWD/etc/supervisord.conf
/etc/supervisord.conf
