Tag: Service disconnected name with success failure MD5 Code Direct

The purpose of writing a Python script, every time after the Windows edit the file, want to sync to Linux, only to log on to the server, and then use the network copy, the repetition is very large, think of can write a small script to help me synchronize

Logic: Compared to the local and server files MD5, if the MD5 inconsistent, then back up the files on the server, the local to upload up

The code is divided into Windows and server side, some things, let Python one do, write a little tired, think, can the server to provide a port, Windows to call this interface, to complete part of the work

The Python code is as follows:

Additional installation of the Baowei is Paramiko, installation method: Pip install Paramiko can be, code as follows, using Paramiko Sshclient to invoke the server to write its own API (hey, call it API), transport to implement the Sftp file upload,

Linux writes its own API:

#!/bin/Bash #判断参数的个数是否大于等于1if[$#-ge1]; Then#定义文件夹 Root_dir="/root/nginx_02/"Backdir="/root/.backup/"Abs_filename= $root _dir$1#判断是否有这个文件if[-F $abs _filename]; Then#利用md5sum工具获取文件的md5值 getfilemd5= ' Md5sum $abs _filename |awk '{print $}'`        Echo "$GETFILEMD 5"#判断第二个参数是否是moveif['Move'== $2]; Then#判断是否存在备份目录, none exists, then move to backup directoryif[-D $backdir]; ThenNowtime=`Date+"%f_%h:%m:%s"`                                MV$abs _filename $backdir $1_$nowtimeif[0-eq $? ]; Then                    Echo "Move Successful"                Else                    Echo "Move failed"                fi                            Else                mkdir-P $backdirfi        fi            Else#报错, there's no such file.Echo "$ No such file or directory"    fiElse#报错, parameter errorEcho "Parameter Error"fi    

The following functions are ultimately implemented:
