这篇教程用Python实现定时备份Mongodb数据并上传到FTP服务器写得很实用，希望能帮到您。
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：# python3.6.1import zipfileimport osimport datetimefrom 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 desName3.4. 文件上传到FTP服务器上：# 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 res3.5. 主程序：# mainbackupTime = 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

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 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： enter ftpUpload*get* ''Traceback (most recent call last): File "AutoBackupMongoTest.py", line 64, in <module> ftp_res = ftpUpload(zip_des_name, ftpUploadFolder) File "AutoBackupMongoTest.py", line 42, in ftpUpload ftp.connect('172.16.7.107', 21) File "E:/Miniconda/lib/ftplib.py", line 155, in connect self.welcome = self.getresp() File "E:/Miniconda/lib/ftplib.py", line 234, in getresp resp = self.getmultiline() File "E:/Miniconda/lib/ftplib.py", line 220, in getmultiline line = self.getline() File "E:/Miniconda/lib/ftplib.py", line 208, in getline raise EOFErrorEOFError或者是如下错误： enter ftpUploadTraceback (most recent call last): File "AutoBackupMongoTest.py", line 63, in <module> ftp_res = ftpUpload(zip_des_name, ftpUploadFolder) File "AutoBackupMongoTest.py", line 41, in ftpUpload ftp.connect("192.168.0.101", 21) File "E:/Miniconda/lib/ftplib.py", line 152, in connect source_address=self.source_address) File "E:/Miniconda/lib/socket.py", line 722, in create_connection raise err File "E:/Miniconda/lib/socket.py", line 713, in create_connection sock.connect(sa)TimeoutError: [WinError 10060] 由于连接方在一段时间后没有正确答复或连接的主机没有反应，连接尝试失败。到此这篇关于用Python实现定时备份Mongodb数据并上传到FTP服务器的文章就介绍到这了,更多相关Python 定时备份Mongodb内容请搜索51zixue.net以前的文章或继续浏览下面的相关文章希望大家以后多多支持51zixue.net！
