     *  实战应用

## 1. Salt yaml配置文件使用Jinja2模板介绍 ##

jinja2官方网站：  
[http://jinja.pocoo.org/][http_jinja.pocoo.org]

### 1.1 File状态使用template参数 ###

- template: jinja

### 1.2 模板文件里面变量使用`{ { 名称 }}` ###

{ { PORT }}

### 1.3 变量列表 ###

- defaults:   PORT: 8080

## 2. 实战应用 ##

添加监听主机和端口变量

`vim /srv/salt/devfiles/httpd.conf`

Listen { { HOST }}:{ { PORT }} # { { MAC }}

配置salt master配置文件、pillar配置文件、lamp.sls添加jinja模板：

[root@salt-master112 dev]# egrep -v '^$|^[#]' /etc/salt/master
    state_top: top.sls
    file_roots:
      base:
        - /srv/salt   dev:
        - /srv/salt/dev   test:
        - /srv/salt/test   prod:
        - /srv/salt/prod pillar_roots:
      base:
        - /srv/salt/pillar   dev:
        - /srv/salt/dev/pillar [root@salt-master112 dev]# cat /srv/salt/pillar/top.sls 
    dev:
      'node*.test.com':
        - apache [root@salt-master112 dev]# cat /srv/salt/dev/pillar/apache.sls 
    apache:
      HOST: {
       { grains['fqdn_ip4'][0] }}
      PORT: 8080
      MAC: {
       { salt['network.hw_addr']('eth0') }}
    [root@salt-master112 dev]# salt '*' saltutil.refresh_pillar

    [root@salt-master112 dev]# salt '*' pillar.items            
    master.test.com:

                8080
    [root@salt-master112 dev]# cat /srv/salt/dev/lamp.sls 
    lamp-pkg-install:
      pkg.installed:
        - names:       - php       - php-fpm       - mysql       - php-mysql       - php-pdo
