jinjia模板

需求：想讓saltstack的file模塊分發到minion端的配置文件監聽minion端的IP和端口，如何用變量實現？看下面！！

一、jinja模板加grains使apache監聽本地端口

# cat lamp.sls 
lamp-install:
  pkg.installed:
    - pkgs:
      - httpd
      - php
      - php-pdo
      - php-mysql

apache-config:
  file.managed:
    - name: /etc/httpd/conf/httpd.conf
    - source: salt://web/files/httpd.conf
    - user: root
    - group: root
    - mode: 644
    - template: jinja       #指定使用jinja模板
    - defaults:     #變量列表
      PORT: 80     #端口變量
      IPADDR: {{ grains['fqdn_ip4'][0] }}     #ip變量{此變量使用grains獲取的IP地址}
    - require:
      - pkg: lamp-install

apache-auth:
  pkg.installed:
    - name: httpd-tools
    - require_in:
      -cmd: apache-auth
  cmd.run:
    - name: htpasswd -bc /etc/httpd/conf/htpasswd_file admin admin
    - unless: test -f /etc/httpd/conf/htpasswd_file 

apache-conf:
  file.recurse:
    - name: /etc/httpd/conf.d
    - source: salt://web/files/apache-conf.d
    - watch_in:
       - service: lamp-service

php-config:
  file.managed:
    - name: /etc/php.ini
    - source: salt://web/files/php.ini
    - user: root
    - group: root
    - mode: 644
    - watch_in:
      - service: lamp-service

lamp-service:
  service.running:
    - name: httpd
    - enable: True
    - reload: True
    - watch:
      - file: apache-conf
      - file: apache-config

1.一、修改apache-config狀態下的source指定的配置文件

# sed -n '42p' /srv/salt/base/web/files/httpd.conf
Listen {{ IPADDR }}:{{ PORT }}

注：將以前的Listen 80改成Listen {{ IPADDR }}:{{ PORT }}
