##python案例##

一、文件目录案例

Ⅰ、文件目录按关键词备份迁移

#!/usr/bin/env python
# -*- coding:utf-8 -*-
import  os
import shutil
#
# 处理文件及目录
# @a_srcPath 目录路径
# # copyOrMove 复制操作还是移动操作 False为复制操作，True为移动操作
 
allfile = []
def handle_dir(a_srcPath, a_findKey, a_copyOrMove=False):
    srcPathList = os.listdir(a_srcPath)
    #print(str(srcPathList))
    for sPath in srcPathList:
        filepath = os.path.join(a_srcPath, sPath)
        # print("filepath="+filepath)
        # 判断是目录
        if os.path.isdir(filepath):
          handle_dir(filepath, a_findKey, a_copyOrMove)
          if filepath.find(a_findKey)>=0:
             len_asrcPath = len(srcPath_root)
             destPath= destPath_root+filepath[len_asrcPath:]
             # destPath = filepath
             #print("destPath="+destPath)
             #print("filepath=" + filepath)
             allfile.append(destPath)
             if a_copyOrMove:  
                 shutil.move(filepath, destPath)    #移动目录
             else:
                 shutil.copytree(filepath, destPath) #复制目录
 
    return allfile
 
findKey='2018-'
srcPath_root='/home/mysoft/attachments'
destPath_root='/home/mysoft/bk/attachments_history/'+findKey
 
allfiles=handle_dir(srcPath_root,findKey,False)
 
for item in allfiles:
   print(item)

Ⅱ、日志切割

import os, sys, datetime,re

# nginx日志存放的路径
nginxLogPath="/opt/nginx-1.9.5/logs/"
# 获取昨天的日期
yesterday = (datetime.date.today() + datetime.timedelta(days = -1)).strftime("%Y-%m-%d")
# nginx启动的pid文件
PID = "/var/run/nginx.pid"

def cutNginxLog(path):
    """
    切割nginx日志函数
    :param path: 日志文件的第一级目录
    :return: 
    """
    logList = os.listdir(path)    # 判断传入的path是否是目录
    for logName in logList:      # 循环处理目录里面的文件
        logAbsPath = os.path.join(path, logName)
        if os.path.isdir(logAbsPath):   # 如果是目录，递归调用自己，继续处理
            cutNginxLog(logAbsPath)
        else:         # 如果是日志文件，就进行处理
            # 分割日志
            re_Num = re.compile(r'^[a-zA-Z]')
            # 判断日志文件是否是字母开头，如果是日期开头就不切割
            if re_Num.search(logName):
                logNewName = yesterday + "_" + logName          # 新日志文件名称列如：2018-11-8_access.log
                oldLogPath = os.path.join(path, logName)        # 旧日志文件绝对路径
                newLogPath = os.path.join(path, logNewName)     # 新日志文件绝对路径
                os.rename(oldLogPath, newLogPath)

    cmd = " kill -USR1 `cat %s` "% PID
    res = os.system(cmd)
    if res != 0:
        return "重新加载nginx失败"
cutNginxLog(nginxLogPath)

二、监控案例

Ⅰ：监控端口

#验证端口是否正常<br>import socket
 
def get_ports(port):
    sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
    result = sock.connect_ex(('127.0.0.1',port))
    print(result)  #输出返回码
    if result != 0:
       send_data = "服务器的%d",port,'端口挂了，快去修复哈'
       print (send_data)
    else:
       print("端口:",port,"正常")
