SaltStack数据系统之Grains、Pillar
# vim /etc/salt/master pillar_roots：base:
- /srv/pillar/base
prod:
- /srv/pillar/prod
#此段代码定义了base环境下的Pillar文件保存在/srv/pillar/base目录下。prod环境下的Pillar文件保存在/srv/pillar/prod下。
# mkdir -p /srv/pillar/{base,prod}
# tree /srv/pillar/
/srv/pillar/
├── base
└── prod
# systemctl restart salt-master
#创建base环境下的pillar文件为apache
# vim /srv/pillar/base/apache.sls
{% if grains['os'] == 'CentOS' %}
apache: httpd
{% elif grains['os'] == 'Debian' %}
apache: apache2
{% endif %}
#与State相似，Pillar也有top file，也使用相同的匹配方式将数据应用到minion上。示例如下：
# vim /srv/pillar/base/top.sls
base:
'*':
- apache
# salt '*' pillar.items
linux-node1.example.com:

linux-node2.example.com:

#在base环境下，引用pillar
# vim /srv/salt/base/web/apache.sls
