本文介绍了如何在SaltStack中创建自定义模块，并通过示例展示了如何获取主机信息，包括IP地址、主机名、磁盘、内存、BIOS和CPU信息。通过saltutil.sync_modules命令同步模块，并验证了模块的正确执行。

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

[root@v72 _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

[root@v72 _modules]# pwd

/srv/salt/_modules

[root@v72 _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

[root@v72 _modules]# salt '*' saltutil.sync_modules

v72:

- modules.infos

v73:

- modules.infos

运行，验证

[root@v72 _modules]# salt '*' infos.getallinfos

v73:

- IP地址: 192.168.156.73 192.168.122.1

- 主机名: v73

- 磁盘信息: 文件系统容量已用可用已用% 挂载点
