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
Python:3.6.1Python IDE:pycharm系统:win7

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 EOFError EOFError
或者是如下错误:
