Python 运用Paramiko实现批量巡检

通过封装Paramiko这个SSH模块，我们可以实现远程批量管理Linux主机，在此基础上配合钉钉API接口可实现自动告警机制，定期自动检查设备状态，并推送到钉钉群内。

首先需要配置双网卡模式，我们将无线网卡配置路由让其走外网与钉钉连接，有线网口则负责与内部服务器相连接，只需要配置路由即可实现。

网络目标 网络掩码 网关 接口 跃点数
0.0.0.0 0.0.0.0 132.35.93.1 132.35.93.11 21
0.0.0.0 0.0.0.0 192.168.191.1 192.168.191.3 25

C:\Windows\system32> route delete 0.0.0.0

# 所有的外网访问走无线网卡，从网关 192.168.191.1 出去
C:\Windows\system32>route -p add 0.0.0.0 mask 0.0.0.0 192.168.191.1

# 如果是132网段，则走内部，网关为：132.35.93.1
C:\Windows\system32>route -p add 132.35.0.0 mask 255.255.0.0 132.35.93.1

封装钉钉接口： 接口的调用需要传入需要通知特定人的手机号，这个模块命名为Ding.py 代码如下。

import requests
import urllib.parse
import datetime,time,hmac,hashlib,base64,json

class DingToken():
def __init__(self,atAll,atMobiles):
self.atAll = atAll
self.atMobiles = atMobiles

def send_message(self,message):
timestamp = str(round(time.time() * 1000))
secret = 'SEC1018485caf7339e38530b'
secret_enc = secret.encode('utf-8')
string_to_sign = '{}\n{}'.format(timestamp, secret)
string_to_sign_enc = string_to_sign.encode('utf-8')
hmac_code = hmac.new(secret_enc, string_to_sign_enc, digestmod=hashlib.sha256).digest()
sign = urllib.parse.quote(base64.b64encode(hmac_code))

headers={'Content-Type': 'application/json'}
webhook = 'https://oapi.dingtalk.com/robot/send?access_token=0fe10f&timestamp=' + timestamp + "&sign=" + sign
data = {
"msgtype": "text",
"text": {"content": message },
"at": {

}
}
requests.post(webhook, data=json.dumps(data), headers=headers)

# 发送警告信息

self.send_message(

"告警类型: \t {5} \n"
"------------------------------------------------------- \n"

"-------------------------------------------------------".
format(platform,person,group,address,send_date,type,message) )

# 发送Ping连通性报告
def send_ping(self,platform,send_date,success_len,error_len,error_list):
self.send_message(
"------------------------------------------------------- \n"
"\t\t\t\t\t {0} \n"

)

if __name__ == "__main__":

ding.send_warning("总部客服","王瑞","CTI服务组","192.168.1.1","2021:01:01","磁盘异常","C:// \t 100% \n")

以磁盘为例，当超过了我们定义好的阈值时，则会通过钉钉提示用户告警，告警提示如下。

定义配置文件： 配置文件则是巡检时需要解析的内容，我们需要依次写入账号密码等信息。

实现正则解析： 前面的配置无法实现交互式问答，智能机器人推送数据，很被动，我们需要开启交互机器人，自己实现业务逻辑。

import os,sys,re

def participle(text):
ref = re.findall(r'(25[0-5]|2[0-4]\d|[0-1]\d{2}|[1-9]?\d)\.(25[0-5]|2[0-4]\d|[0-1]\d{2}|[1-9]?\d)\.(25[0-5]|2[0-4]\d|[0-1]\d{2}|[1-9]?\d)\.(25[0-5]|2[0-4]\d|[0-1]\d{2}|[1-9]?\d)',text)
address = ".".join(ref[0])
select = re.findall('查询', text)

if(len(address) !=0 and len(select) != 0):
if len (re.findall('内存',text)) != 0:
return [address,"内存"]
elif len (re.findall('磁盘',text)) != 0:
return [address,"磁盘"]
elif len (re.findall('负载',text)) != 0:
return [address,"负载"]

if __name__ == "__main__":
text = "帮我查询192.168.1.1主机的内存负载情况"
text2 = "帮我查询 192.168.1.200 这 台设 备的 磁盘 使用率"
text3 = "需要查询192.168.1.200 设备中负载使用情况，请反馈结果"
text4 = "发现负载出现告警，请立即查询192.168.1.200这台设备的负载使用率，并立即反馈"

print(participle(text))
print(participle(text2))
print(participle(text3))
print(participle(text4))

txt = '''
主编单位：总部客服系统
'''
addr = re.findall('(主编单位：.*?)\s', txt)[0]
print(addr)

这个案例，从文本中提取可用信息，并将其返回为列表格式。

接着配置钉钉开发者平台机器人，此处需要有公网地址，作用是，钉钉群有人at机器人时，机器人会将请求post发送到我们的django应用服务上。

使用django配置接收请求并处理即可，处理代码如下所示。

from django.http import HttpResponse, JsonResponse
import json,hmac,hashlib,base64
import sys,os,re

# 机器人 app_secret
app_secret = "LcKEf0nlqe"

# 根据IP查询操作使用
def select_participle(text):
ref = re.findall(r'(25[0-5]|2[0-4]\d|[0-1]\d{2}|[1-9]?\d)\.(25[0-5]|2[0-4]\d|[0-1]\d{2}|[1-9]?\d)\.(25[0-5]|2[0-4]\d|[0-1]\d{2}|[1-9]?\d)\.(25[0-5]|2[0-4]\d|[0-1]\d{2}|[1-9]?\d)',text)

# 判断如果地址不为空，则进行查询等操作
if len(ref) != 0:
address = ".".join(ref[0])
select = re.findall('查询', text)
if(len(address) !=0 and len(select) != 0):
if len (re.findall('内存',text)) != 0:
return [address,"内存"]
elif len (re.findall('负载',text)) != 0:
return [address,"负载"]
else:
if len(re.findall('主机列表', text)) != 0:
return ["主机列表"]

def index(request):
if request.method == "POST":
HTTP_SIGN = request.META.get("HTTP_SIGN")
HTTP_TIMESTAMP = request.META.get("HTTP_TIMESTAMP")
res = json.loads(request.body)

# 接收用户的输入并做处理
sendnick = res.get("senderNick")
is_admin = res.get("isAdmin")
conver = res.get("conversationTitle")
content = res.get("text").get("content")
print("发送人: {} 是否管理员: {} 所在组: {} 接收数据: {}".format(sendnick,is_admin,conver,content))

# 数据的加密解密
string_to_sign = '{}\n{}'.format(HTTP_TIMESTAMP, app_secret)
string_to_sign_enc = string_to_sign.encode('utf-8')
hmac_code = hmac.new(app_secret.encode("utf-8"), string_to_sign_enc, digestmod=hashlib.sha256).digest()
sign = base64.b64encode(hmac_code).decode("utf-8")

ref_select_text = select_participle(content)

if len(ref_select_text) == 2:
if sign == HTTP_SIGN:
if "负载" in ref_select_text[1]:
return JsonResponse(
{"msgtype": "text",
"text": {
"content": "经过查询,主机: {} 负载率为: 10% 当前为正常状态".format(ref_select_text[0])
}
})

if "内存" in ref_select_text[1]:
return JsonResponse\
(
{"msgtype": "text",
"text":
{
"content": "经过查询,主机: {} 内存占用率为: 70% 当前为正常状态".format(ref_select_text[0])
}
}
)
elif len(ref_select_text) == 1:
if "主机列表" in ref_select_text[0]:
return JsonResponse \
(
{"msgtype": "text",
"text":
{
"content": "目前您所管理的主机，总结: 205台"
}
}
)
return JsonResponse({"error": "没有权限"})
if request.method == "GET":
return HttpResponse("没有权限")

django运行后，我们回到钉钉群内，问机器人一些问题看看吧，前提是这些问题已经定义了正则解析。

django 后台则能够接收到，这些数据，并做出回应。
