实现的功能:在win7下,每天晚上1点,自动将 f:/data中所有文件进行压缩,以[mongodb+日期]命名,将压缩好的文件存储在本地目录 f:\mongodbdata\,然后将这个压缩好的文件上传到ftp://192.168.0.101/mongodbup/目录下
分三步:
第一步:搭建ftp服务器,配置好ftp环境。 第二步:用python编写压缩文件并实现ftp上传的脚本第三步:使用win7自带的任务计划程序定时执行python脚本
1. 环境
python:3.6.1python ide:pycharm系统:win7
2. 搭建ftp服务器,配置好ftp环境
2.1. 启用ftp和iis服务器
注意:要全部展开,勾选上。
2.2. 添加ftp服务器
2.3. 设置参数
2.4. 设置成功,访问
3. 用python编写压缩文件并实现ftp上传的脚本
3.1. import包:
1
2
3
4

|
# python3.6.1 import zipfile import os import datetime from ftplib import ftp |
3.2. 定义配置信息:

|
# 定义配置信息 srcfolder = r "f:\data" # 被压缩的源数据,文件夹形式 desfolder = r 'f:\mongodbdata\\' # 压缩好的数据临时存放的位置 ftp_url = "192.168.0.101" # ftp服务器地址 ftp_port = 21 # ftp服务端口号 ftpuploadfolder = "mongodbup" # 压缩数据在ftp服务器上存放的位置 |
3.3. 压缩数据源(文件夹):

# 压缩文件夹 def zipfolder(srcfolder, desfolder, date): ''' :param srcfolder: 被压缩的源数据位置 :param desfolder: 压缩之后文件的存放路径 :param date: 执行压缩的当前时间,datetime产生(ext:2017-08-16 14:56:40.872613) :return: 压缩文件的路径 ''' starttime = datetime.datetime.now() print (f "enter func zipfolder, time:{starttime}" ) desname = f "{desfolder}mongodb{date.year}{date.month}{date.day}.zip" # 检查是否已经压缩过了 if os.path.exists(desname): endtime = datetime.datetime.now() print (f "already exsist, leave func zipfolder, time:{endtime}, usedtime:{endtime-starttime}" ) return desname z = zipfile.zipfile(desname, 'w' , zipfile.zip_deflated) for dirpath, dirnames, filenames in os.walk(srcfolder): print (f "dirpath:{dirpath}, dirnames:{dirnames}, filenames:{filenames}" ) for filename in filenames: try : # mongodb在运行时,有几个关于lock的文件无法压缩,为了避免程序终止,忽略这几个文件 z.write(os.path.join(dirpath, filename)) except exception as e: print (f "except: {e}, cannot zip file: {dirpath}{filename}" ) z.close() endtime = datetime.datetime.now() print (f "zip done, leave func zipfolder, time:{endtime}, usedtime:{endtime-starttime}" ) return desname |

# 上传文件至ftp服务器 def ftpupload(filename, folder, ftp_url, ftp_port): ''' :param filename: 待上传文件路径 :param folder: 文件上传至ftp服务器上的存储目录 :param ftp_url: ftp服务器ip :param ftp_port: 端口号,默认为21 :return: status code ''' starttime = datetime.datetime.now() print (f "enter func ftpupload, time:{starttime}" ) ftp = ftp() ftp.set_debuglevel( 2 ) # set debug level, detail info:2, close:0 ftp.connect(ftp_url, ftp_port) ftp.login(' ', ' ') # 登录,如果匿名登录则用空串代替 print (ftp.getwelcome()) # ext: *welcome* '220 microsoft ftp service' ftp.cwd(folder) # change to a directory on ftp server bufsize = 1024 # 设置缓冲块大小 file_handler = open (filename, 'rb' ) # 读模式在本地打开文件 res = - 1 try : # 为了避免程序终止,忽略可能出现的错误 res = ftp.storbinary(f "stor {os.path.basename(filename)}" , file_handler, bufsize) # upload file except exception as e: print (f "except: {e}, cannot upload file: {ftp_url}:{ftp_port} {filename}" ) finally : ftp.set_debuglevel( 0 ) # 关闭debug信息 file_handler.close() ftp.quit() endtime = datetime.datetime.now() print (f "upload done, leave func ftpupload, time:{endtime}, usedtime:{endtime-starttime}" ) return res |
3.5. 主程序:

# main backuptime = datetime.datetime.now() zip_des_name = zipfolder(srcfolder, desfolder, backuptime) print (zip_des_name) ftp_res = ftpupload(zip_des_name, ftpuploadfolder, ftp_url, ftp_port) print (f "ftp_res: {ftp_res}" ) |
4. 使用win7自带的任务计划程序定时执行python脚本
位置:开始 ——> 附件 ——> 系统工具 ——> 任务计划程序
不需要时,右键——>删除任务 即可
5. 效果
5.1. 本地生成的压缩文件
5.2. 上传至ftp服务器的压缩文件
5.3. 详细信息-性能-时间
日志信息:
源文件data总共8.7g,压缩后5.3g,压缩时间20m,局域网内上传时间18m。

6. 注意事项
6.1. ftp服务器ip地址变更处理
6.1.1. 第一步,修改ftp服务器站点配置。
6.1.2. 第二步,修改代码中ftp登录ip
1
|
ftp.connect( "172.16.7.107" , 21 ) |
6.1.3. 出错信息 如果只是单纯按照6.1.2 修改登录ip,没有修改ftp服务器站点设置的话,将会出现如下莫名其妙的错误:
