在master上面打开系统自带的pillar:# vim /etc/salt/master
556 pillar_opts: True
# /etc/init.d/salt-master restart
Stopping salt-master daemon: [确定]
Starting salt-master daemon: [确定]
# salt '*' pillar.items =======>显示系统自带的pillar
pillar的应用场景:
1 敏感数据：如用户名与密码
2 处理差异性变量
# vim /etc/salt/master ==========>打开如下选项
533 pillar_roots:

535 - /srv/pillar
556 pillar_opts: False
# mkdir pillar
# /etc/init.d/salt-master restart
Stopping salt-master daemon: [确定]
Starting salt-master daemon: [确定]
实例1：
# cat /srv/pillar/apache.sls
{% if grains['os'] == 'CentOS' %} 如果系统是CentOS
apache: httpd 则显示httpd
{% elif grains['os'] == 'Debian' %} 如果系统是Debian
apache: apache2 则显示apache2
{% endif %}
# cat /srv/pillar/top.sls ========>pillar的top file文件
base:
'*':
- apache
# salt '*' pillar.items ========>获取pillar的值
