[英]Fabric not working with cron job
I'm trying to run a deploy script using pexpect and Fabric. 我正在尝试使用pexpect和Fabric运行部署脚本。 This is what is happening:
这是正在发生的事情:
$ 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
deploy.sh (I'm a total shell scripting newbie, bear with me) deploy.sh (我是一个完全的shell脚本新手,请耐心等待)
#!/bin/bash
EXPECT_FILE=/home/pedregal/Deploy/expectfile.py
LOG_FILE=/home/pedregal/Deploy/deploy.log
touch $LOG_FILE
python $EXPECT_FILE > $LOG_FILE 2>&1
mail -s "Auto-update log" cbustios@elpedregalsa.com < $LOG_FILE
expectfile.py expectfile.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)
fabfile.py fabfile.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')
If I run deploy.sh
manually it runs perfectly fine, however, I'm receiving an email with the following traceback from the cron job: 如果我手动运行
deploy.sh
,它运行得很好,但是,我收到的电子邮件中包含来自cron作业的以下追溯:
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)

'executable: %s.' % self.command)
pexpect.exceptions.ExceptionPexpect: The command was not found or was not executable: fab.
I thought the installation of Fabric was system-wide, what am I missing? 我以为Fabric的安装是整个系统的,我缺少什么?
A cronjob doesn't run load .bash_profile
nor your .bashrc
, these are source'd by your shell. cronjob不会运行load
.bash_profile
或您的.bashrc
,这些都是由您的Shell来的。 But cron
does not run through your shell so you have to setup the required environment variables (eg PATH
) manually from the running script. 但
cron
不通过你的shell,所以你必须设置所需的环境变量(例如运行PATH
)手动运行的脚本中。
Got it working with fabric and python 使用了Fabric和python
me@local $ crontab cron_file.txt 我@本地$ crontab cron_file.txt
