用Python实现定时备份Mongodb数据,并上传到FTP服务器


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:3.6.1
  • Python 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

3. 用python编写压缩文件并实现FTP上传的脚本

  • 3.1. Import包:
# 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
  • 3.4. 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 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}")

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。

用Python实现定时备份Mongodb数据,并上传到FTP服务器

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 EOFError
EOFError

或者是如下错误:

enter ftpUpload
Traceback (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)
