你必须知道的python运维常用脚本

1、你必须知道的python运维常用脚本判断是否是一个目录#!/usr/bin/env python3# -*- coding: utf-8 -*-# Time : 2018-12-18 15:16# Author : opsonly# Site : # File : opsUse.py# Software: PyCharmimport osdir = /var/www/html/EnjoyCarApi/if os.path.isdir(dir): print(%s is a dir % dir)else: print(%s is not a dir % dir)系统内存与磁盘检测#!/usr/bin/env python3# -*- coding: utf-8 -*-# Time : 2018-12-17 17:16# Author : opsonly# Site : # File : systemissue.py# Software: PyCharmimport psutildef memissue(): print(内存信息：) mem = psutil.virtual_memory

2、() # 单位换算为MB memtotal = mem.total/1024/1024 memused = mem.used/1024/1024 membaifen = str(mem.used/mem.total*100) + % print(%.2fMB % memused) print(%.2fMB % memtotal) print(membaifen)def cuplist(): print(磁盘信息：) disk = psutil.disk_partitions() diskuse = psutil.disk_usage(/) #单位换算为GB diskused = diskuse.used / 1024 / 1024 / 1024 disktotal = diskuse.total / 1024 / 1024 / 1024 diskbaifen = diskused / disktotal * 100 print(%.2fGB % diskused) print(%.2fGB % disktotal) print(%.2f % diskbaifen)memissue()p

3、rint(*)cuplist()统计nginx日志前十ip访问量并以柱状图显示#!/usr/bin/env python3# -*- coding: utf-8 -*-# Time : 2018-12-18 15:49# Author : opsonly# Site : # File : nginx_ip.py# Software: PyCharmimport matplotlib.pyplot as plt#nginx_file = nginx2018-12-18_07:45:26ip = # 筛选nginx日志文件中的ipwith open(nginx_file) as f: for i in f.readlines(): s = i.strip().split()0 lengh = len(ip.keys() # 统计每个ip的访问量以字典存储 if s in ip.keys(): ips = ips + 1 else: ips = 1#以ip出现的次数排序返回对象为list http:/f-1.ccip = sorted(ip.items(), key=lambda e:e1,

7、.query(host,A) for i in ip: shost.append(i) return sfor i in query(hosts): print(i,si)清除指定redis缓存#!/usr/bin/env python3# -*- coding: utf-8 -*-# Time : 2018-12-20 15:19# Author : opsonly# Site : # File : redisdel.py# Software: PyCharmimport redis#选择连接的数据库db = input(输入数据库:)r = redis.Redis(host=127.0.0.1,port=6379,db=0)#输入要匹配的键名 id = input(请输入要执匹配的字段：)arg = * + id + *n = r.keys(arg)#查看匹配到键值for i in n: print(i.decode(utf-8)#确定清除的键名delid = input(输入要删除的键：)print(清除缓存 %s 成功 % delid)下载阿里云RDS二进制日志#!/usr/bin/env python3# -*- coding: utf-8 -*-# Time : 2018-12-12 13:52# Author : opsonly# Site : # File : rds_binlog.py# Software: PyCharm查询阿里云rds binlog日志import base64,urllib.requestimport hashlibimport hmacimport uuid,time,json,wgetclass RDS_BINLOG_RELATE(object): def _init_(self): #阿里云的id和key self.access_id = * self.access_key = * #通过id和key来进行签名 def signed(self): timestamp = time.strftime(%Y-%m-%dT%H:%M:%SZ, time.gmtime() header = Action: DescribeBinlogFiles, DBInstanceId: rm-wz9azm783q621n9,
