1、查看MASTER的BASE路径，在对应的路径建立_modules文件夹，存放.py的模块
[[email protected] _modules]# cat /etc/salt/master | grep file_roots -A 5
--
file_roots:
base:
- /srv/salt
建立目录：
mkdir -p /srv/salt/_modules
2、在/srv/salt/_modules目录下编写python代码
[[email protected] _modules]# pwd
/srv/salt/_modules
[[email protected] _modules]# cat infos.py
#!/usr/bin/env python
#encoding: utf-8
from subprocess import Popen, PIPE
import os,sys
import time
def getipaddr():
p = Popen(['hostname','-I'], stdout = PIPE)
ip=p.stdout.read()
return ip
def gethostname():
p = Popen(['hostname'], stdout = PIPE)
hostname=p.stdout.read()
return hostname
def getdiskinfo():
p = Popen(['df','-h'], stdout = PIPE)
disks=p.stdout.read()
return disks
def getmemoryinfo():
p = Popen(['free','-m'], stdout = PIPE)
memorys=p.stdout.read()
return memorys
def getbiosinfo():
p = Popen(['dmidecode','-t','bios'], stdout = PIPE)
bios=p.stdout.read()
return bios
def getcpu():
p = Popen(['sar','-u','1','3'], stdout = PIPE)
time.sleep(3)
cpus=p.stdout.read()
return cpus
def getallinfos():
ip="IP地址: "+getipaddr()
hostname="主机名: "+gethostname()
disk="磁盘信息: "+getdiskinfo()
memory="内存信息: "+getmemoryinfo()
bios="BIOS信息: "+getbiosinfo()
cpu="CPU信息: "+getcpu()
return ip,hostname,disk,memory,bios,cpu
#getallinfos()
3、同步模块，执行验证
[[email protected] _modules]# salt '*' saltutil.sync_modules
v72:
- modules.infos
v73:
- modules.infos
运行，验证
[[email protected] _modules]# salt '*' infos.getallinfos

加载哪一部份的信息，只需要在saltstack上面调用对应的方法就可以了
将来如果需要获取其它的信息，只需要在自定义的模块添加对应的方法，同步，再执行即可
[[email protected] _modules]# cat infos.py | grep getos -A 5
def getos():
status,output=commands.getstatusoutput("uname -a")
return output
注意上面的方法也和上面一样可以获取linux命令的输出，但需要先导入模块
import commands
