Linux环境下给python项目写个启停服务

写个服务，写完后放在/lib/systemd/system路径下

update_rule.server

[Unit]
Description = TinyScan update rule

update_rule.py是一个定时任务

import os

import schedule
import time
import datetime

def job1():
    os.system('/root/TinyScan_Auto_Deploy/init_cve/sSnvd -u')

if __name__ == '__main__':
    # schedule.every(10).seconds.do(job1)
    schedule.every().day.at('11:00').do(job1)
    while True:
        schedule.run_pending()

当然单纯的定时任务可以利用crontab来搞定

crontab定时任务

cat /etc/crontab

crontab -e ： 编辑定时任务（用户可以省略，默认是当前用户）

crontab -l ： 查看定时任务（只查看当前用户的定时任务）

cat /var/log/cron : 可以查看到执行那些定时任务

cat /var/log/messages: 记录系统操作的日志，（例如：用户登录）
