编辑配置文件：/etc/salt/
配置分组，供后续pillar判断参数使用
nodegroups: web1groups: ‘L@db_01‘ web2groups: ‘L@db_02‘
/srv/pillar/top.sls
base: web1groups: - match: nodegroup - web1server web2groups: - match: nodegroup - web2server
master配置的分组web1groups和web2groups参数，分别对应配置下的文件名（web1server.sls和web2server.sls）
/srv/pillar/web1server.sls
nginx:
root: /wwww
/srv/pillar/web2server.sls
nginx:
root: /data
/srv/salt/_grains/NginxGrins.py
import os, sys, commands def NginxGrains(): re = {} max_open_file = 65536 try: getulimit = commands.getstatusoutput(‘source /etc/profile; ulimit -n‘) except Exception , e: pass if getulimit[0] == 0: max_open_file = getulimit[1] re[‘max_open_file‘] = max_open_file return re NginxGrains()
配置过程中，出现问题，可以参考：saltstack-5 grainx组件

配置文件中：
1、使用{{ grains[‘num_cpus‘] }}获取cpu的数量；
2、{{ grains[‘max_open_file‘] }}获取最大的打开文件数；
3、{{ pillar[‘nginx‘][‘root‘] }}获取url路径，pillar又使用分组来判断获取参数；
