学习Ansible发现的Nginx配置问题

《奔跑吧，Ansible》有个小小的问题，它在写下载软件的脚本中没有指定下载的软件的版本，所以我们阅读并执行这些脚本时，往往下载的是最新的版本，最后导致现象不一致。

如下脚本下载并启动一个Nginx，该Nginx支持tls。

- name: Config Webservers With Nginx And TLS
  hosts: webservers
  sudo: True
  vars:
    key_file: /etc/nginx/ssl/nginx.key
    cert_file: /etc/nginx/ssl/nginx.crt
    conf_file: /etc/nginx/sites-available/default/nginx.conf
    server_name: localhost
  tasks:
    - name: Install Nginx
      yum: name=nginx
    
    - name: Create Directories For TLS Certificates
      file: path=/etc/nginx/ssl state=directory
    
    - name: Copy TLS Key
      copy: src=files/nginx.key dest={{ key_file }} owner=root mode=0600
      notify: restart nginx

    - name: Copyt TLS Certificate
      copy: src=files/nginx.crt dest={{ cert_file }}
    
    - name: Generate Nginx Config File
      template: src=templates/nginx.conf.j2 dest={{ conf_file }}

    - name: Enable Configuration
      file: dest=/etc/nginx/sites-enabled/default src={{ conf_file }} state=link
      notify: restart nginx

    - name: Generate Index.html
      template: src=templates/index.html.j2 dest=/usr/share/nginx/html/index.html mode=0644

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

该脚本执行后，并不能Nginx并不能如愿的监听在443端口。观察/etc/nginx/nginx.conf文件后发现，我们的nginx.conf不应该放在/etc/nginx/sites-available/default/nginx.conf，而应该放置在conf.d目录下。

下面为nginx的配置文件，注意查看几个include配置。
