ansible 注册变量 register和jinja语法

1.用ansible做安全自查，形成报告

---
- hosts: huidu
  tasks:
  - name: register shell result to variable
    shell: ps aux|grep 18086|grep -v 'grep'|wc -l
    register: host_ps

  - name: get 18086 count and judge if ok
    debug:
          msg: "{{ host_ps['stdout']}}"

  - name: get ssh version
    shell: ssh -V
    register: ssh_version

  - name: echo ssh -V result
    debug: 
         msg: "{{ ssh_version['stderr_lines'] }}"

  - name: judge root login permission
    shell: cat /etc/ssh/sshd_config|grep -i 'PermitRootLogin'|grep -i yes|wc -l 
    register: root_ssh



  - name: get ps num into a file
    template: src=ps.html.j2 dest=/tmp/ps.html

2.jinja2模板

items                                result                          ok/nook
process num                        {{ host_ps['stdout']}}                                  {% if "{{host_ps['stdout']}}" ==2  %}  ok {% else %}  not ok  {% endif %} 

ssh_version                        {{ ssh_version['stderr_lines']}} 'judge myself'

root_ssh                           {{ root_ssh}}           {% if "{{root_ssh['stdout']}}" != '0' %} ok {% else %} not ok {% endif %}
