结构不适用于cron作业

Question

我尝试使用pexpect和Fabric运行部署脚本。这就是正在发生的事情：

$ crontab -l
# m h  dom mon dow   command
30 04 * * * /bin/bash /home/pedregal/Deploy/deploy.sh

$ ls -l
total 20
-rwxrwxr-- 1 pedregal pedregal  239 Nov 11 09:00 deploy.sh
-rw-rw-r-- 1 pedregal pedregal  271 Nov  9 21:33 expectfile.py
-rw-rw-r-- 1 pedregal pedregal  900 Nov 10 07:28 fabfile.py

部署.sh（我是一个彻头彻尾的shell脚本新手，请耐心等待）

预期文件.py

# -*- coding: utf-8 -*-
import pexpect
import sys

child = pexpect.spawn('fab piura deploy', echo=False)
child.logfile = sys.stdout
child.expect('user:')
child.sendline('cesarbustios')
child.expect('password:')
child.sendline('************')
child.expect(pexpect.EOF)

工厂文件.py

# -*- coding:  utf-8 -*-
from __future__ import with_statement
import os
from os.path import join, dirname

from dotenv import load_dotenv
from fabric.api import cd, env, prefix, run, sudo, warn_only


DOTENV_PATH = join(dirname(__file__), '.env')
GESTAGRO_PATH = '/home/pedregal/Projects/gestagro/gestagro/'
VENV_PATH = '/home/pedregal/Environments/gestagro/venv/bin/activate'
ACTIVATE_VENV = 'source %s' % (VENV_PATH)
load_dotenv(DOTENV_PATH)


def piura():
    env.hosts = [
        'pedregal@192.168.5.20:22',
    ]
    env.passwords = {
        'pedregal@192.168.5.20:22': os.environ.get('PASSWORD_PIURA'),
    }


def deploy():
    with cd(GESTAGRO_PATH), prefix(ACTIVATE_VENV), warn_only():
        run('hg pull -u')
        run('python manage.py migrate --no-color')
        run('python manage.py collectstatic --noinput --no-color')
        sudo('nginx -s reload')
        sudo('supervisorctl restart gestagro')

如果我手动运行deploy.sh，它运行得非常好，但是，我收到一封电子邮件，其中包含来自cron作业的以下回溯：

Traceback (most recent call last):
  File "/home/pedregal/Deploy/expectfile.py", line 5, in <module>
    child = pexpect.spawn('fab piura deploy', echo=False)
  File "/usr/local/lib/python2.7/dist-packages/pexpect/pty_spawn.py", line 194, in __init__
    self._spawn(command, args, preexec_fn, dimensions)
  File "/usr/local/lib/python2.7/dist-packages/pexpect/pty_spawn.py", line 267, in _spawn
    'executable: %s.' % self.command)
pexpect.exceptions.ExceptionPexpect: The command was not found or was not executable: fab.

我以为织物的安装是全系统的，我遗漏了什么？在

Answer 1

cronjob不运行load .bash_profile也不运行您的.bashrc，这些都是由shell提供的源代码。但是cron不在shell中运行，因此必须从运行脚本手动设置所需的环境变量（例如PATH）。在

Answer 2

让它和织物和Python一起工作

在我@本地$crontab cron公司_文件.txt在

路径=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin SHELL=/bin/bash
