Question

我在Playbook中有一个任务，试图通过处理程序按照惯例重新启动nginx：

- name: run migrations
  command: bash -lc "some command"
  notify: restart nginx

然而，剧本打破了这个错误：

NOTIFIED: [deploy | restart nginx] ******************************************** 
failed: [REDACTED] => {"failed": true}
msg: failure 1 running systemctl show for 'nginx.service': Failed to get D-Bus connection: No connection to service manager.

处理程序是标准的：

- name: restart nginx
  service: name=nginx state=restarted enabled=yes

我设置nginx的方式也不同寻常：

- name: install nginx
  apt: name=nginx state=present
  sudo: yes

- name: copy nginx.conf to the server
  template: src=nginx.conf.j2 dest=/etc/nginx/nginx.conf
  sudo: yes

- name: delete default virtualhost
  file: path=/etc/nginx/sites-enabled/default state=absent
  sudo: yes

- name: add mysite site-available
  template: src=mysite.conf.j2 dest=/etc/nginx/sites-available/mysite.conf
  sudo: yes

- name: link mysite site-enabled
  file: path=/etc/nginx/sites-enabled/mysite src=/etc/nginx/sites-available/mysite.conf state=link
  sudo: yes

这是ubuntu-14-04-x64 VPS。

Answer 1

处理程序是：

- name: restart nginx
  service: name=nginx state=restarted enabled=yes

似乎状态和启用的标志不能同时存在。通过修改以上内容，它起作用了。

- name: restart nginx
  service: name=nginx state=restarted

为什么会这样，为什么它突然突然爆发，我不知道。

Nginx无法通过Ansible重新启动
