Ansible 上的 Supervisorctl 错误：[Errno 111] 连接被拒绝：文件：/usr/lib/python2.7/socket.py

Question

看起来主管存在一些问题：https://stackoverflow.com/questions/18859063/supervisor-socket-error-issue

我尝试了解决方案，基本上是在 Ansible 中的每个 Supervisorctl 调用中添加“config”文件路径，但无济于事。有人能帮我弄清楚到底发生了什么吗？

我在 Ubuntu 14.04 目标上运行这个脚本，它在此之前有很多配置可以运行（但与主管无关）。

Answer 1

在使用 Supervisorctl 之前，您是否已经启动了 Supervisord？

- name: Ensure supervisord is running
  service: name=supervisor state=started
