cronjob中的python多线程问题没有执行

Question

我有一个 script.py 调用其他多处理脚本如下我的 scripts.py:

import os
from multiprocessing import Pool

scriptspy = [
    '/pyscripts/apoiont01.py',
    '/pyscripts/access.py',
    '/pyscripts/dental.py',
    '/pyscripts/cremers.py',
    '/pyscripts/delcuritib.py',
    '/pyscripts/dtalndes.py',
    '/pyscripts/lobo.py',
    '/pyscripts/ierre.py',
    '/pyscripts/daster.py',
    '/pyscripts/dsul.py',
    '/pyscripts/doema.py',
    '/pyscripts/maz.py',
    '/pyscripts/deura.py',
    '/pyscripts/der.py',
    '/pyscripts/dlo.py',
    '/pyscripts/deoltda.py',
    '/pyscripts/dpeed.py',
    '/pyscripts/derr.py',
    '/pyscripts/dweb.py',
]


def roda_processo(processo):
    os.system('python3.7 {}'.format(processo))


for s in scriptspy:
    roda_processo(s)

我的 crontab -e:

* * * * 1,5 /usr/local/bin/python3.7 /pyscripts/scripts.py > /pyscripts/logs/scripts.log

有趣的是，如果我在终端上运行相同的手动运行命令：/ usr / local / bin / python3. 7 /pyscripts/scripts.py > / pyscripts/logs / scripts.log 它运行正常。

您应该将其替换为具有 Python 解释器完整路径的版本，因为从 cron 运行的任何内容都缺少“通常”的环境变量设置，即 PATH 是您最缺少的：

def roda_processo(processo):
    os.system('/usr/local/bin/python3.7 {}'.format(processo))
