python用作监控

一.python日志模块

二.python数据库连接

三.时间处理模块

四.python传递参数给shell

五.发送邮件(py2.7)

六.python计划任务

七.supervisor

/etc/supervisor.conf
[program:check]
command = python /data/remote_back/checkbackup.py
directory = /data/remote_back
user = root

[email protected]_TMN_Data:[/data/remote_back]supervisorctl 
check          RUNNING    pid 5771, uptime 19:15:25
