salt '' saltutil.sync_grains
salt '' saltutil.sync_modules
语法如下：{{ grains.['ip_interfaces'] }}
如下是通过grains获得的minion服务器的信息：

依然使用上一篇salt部署zabbix来举例，部署完成后，额希望吧配置文件中的Hostname= “ ”
的值改成各自机器的ip地址，这样动态获取比一台一台去改快很多，
# Mandatory: no
# Default:
# Hostname=
Hostname={{ grains['ip_interfaces']['eth0'][0] }}
### Option: HostnameItem
# Item used for generating Hostname if it is undefined. Ignored if Hostname is defined.
# Does not support UserParameters or aliases.
#
# Mandatory: no
# Default:
替换完成后，我们执行下：
[root@centos2 conf]# salt ubuntu state.sls cp saltenv=base test=true

从执行结果上看到：

我们通过测试运行 ，这里已经将zabbixagent中Hostname=Zabbix server动态改成了对应agent的ip地址
