通过via服务器调用ansible-playbook
通过via服务器调用ansible-playbook
提问于 2017-11-22 01:39:57
我使用的是运行ubuntu16.04的虚拟机，并且已经在上面安装了ansible v2.4和apache2。我创建了一个cgi脚本'ansible_call.py‘，它使用子进程模块，特别是
import os
import subprocess
print 'Content-type:text/html /r/n/r/n'
with open(os.devnull, 'w') as devnull:
result = subprocess.check_output(['/usr/bin/ansible-
playbook','/vagrant/playbooks/sample.yml'], stderr=devnull)
print result然后，我使用curl向the服务发出请求。
curl localhost/cgi-bin/ansible-call.py但是，我得到了以下错误
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>500 Internal Server Error</title>
</head><body>
<h1>Internal Server Error</h1>
<p>The server encountered an internal error or
misconfiguration and was unable to complete

<p>Please contact the server administrator at

<p>More information about this error may be available
in the server error log.</p>
<hr>
<address>Apache/2.4.18 (Ubuntu) Server at localhost Port 80</address>
</body></html>我查看了日志，发现了以下内容
[Tue Nov 21 17:34:50.192002 2017] [cgi:error] [pid 3142:tid 140333400639232] [client 127.0.0.1:37534] AH01215: subprocess.CalledProcessError: Command '['/usr/bin/ansible-playbook', '/vagrant/playbooks/sample.yml']' returned non-zero exit status 2: /usr/lib/cgi-bin/ansible-call.pypython脚本本身运行正常。退出状态2对我来说是个谜，有谁知道吗？

请检查ansible "executable"以获取可能的状态代码：
以下是一些摘录：
except AnsibleOptionsError as e:
...
exit_code = 5
except AnsibleParserError as e:
...
exit_code = 4
# TQM takes care of these, but leaving comment to reserve the exit codes
# except AnsibleHostUnreachable as e:
# ...
# exit_code = 3
# except AnsibleHostFailed as e:
# ...
# exit_code = 2
except AnsibleError as e:
...
exit_code = 1
except KeyboardInterrupt:
...
exit_code = 99
except Exception as e:
...
exit_code = 250所以退出代码2表明您有失败的主机。您可能希望捕获流程异常：
try:
res = check_output(cmd)
except CalledProcessError as e:
print 'Error occurred: (Code {}) {}'.format(e.returncode, e.output)
res = None页面原文内容由Stack Overflow提供。腾讯云小微IT领域专用引擎提供翻译支持
