Python备份Mysql脚本
代码如下:
#!/usr/bin/python import os import time import ftplib import traceback #config vars systempathchr="/" #路径分割符,*nix用"/" win32用"\\" dbuser="root" #数据库用户名 dbpwd="dbpwd" #数据库密码 dbnamelist=["dbone","dbtwo","dbthree"] #需要备份那些数据库 workdir="/path/to/backup/" #本地备份文件夹 errlogfile="databack.log" #错误日志名 ftp_addr="192.168.0.2" #ftp地址 ftp_port="2102" #ftp端口 ftp_user="databack" #ftp用户名 ftp_pwd="backpwd" #ftp密码 ftp_path="/" #存放到ftp路径 ftpqueue=[] def ftpstor(): #login bufsize=1024 ftp=ftplib.FTP() try: ftp.connect(ftp_addr,ftp_port) ftp.login(ftp_user,ftp_pwd) ftp.cwd(ftp_path) for filepath in ftpqueue: #open file for input as binary f=open(filepath,"rb") #store file as binary print getfilename(filepath) ftp.storbinary("STOR "+getfilename(filepath),f,bufsize) f.close() ftp.quit() except: path=os.path.join(workdir,errlogfile) traceback.print_exc(file=open(path,"a")) def dumpdb(dbname): global ftpqueue timeformat="%Y%m%d" sqlvalformat="mysqldump -u%s -p\"%s\" \"%s\" >\"%s\"" tarvalformat="tar --directory=\"%s\" -zcf \"%s\" \"%s\"" nowdate=time.strftime(timeformat) dumpfile=os.path.join(workdir,dbname+".dump") zipfile=os.path.join(workdir,dbname+nowdate+".tar.gz") sqlval=sqlvalformat % (dbuser,dbpwd,dbname,dumpfile) result=os.system(sqlval) tarval=tarvalformat % (workdir,zipfile,dbname+".dump") result=os.system(tarval) os.remove(dumpfile) ftpqueue.append(zipfile) def getfilename(path): pt=path.rfind(systempathchr) return path[pt+1:] def main(): for dbname in dbnamelist: dumpdb(dbname) ftpstor() main()
没有仔细看,不过下面这两句,推荐看看os.path模块里面的函数,可能就不用针对linux和win分别设定不同的分隔符了 引用
#config vars
systempathchr="/" #路径分割符,*nix用"/" win32用"\\"
看到代码里面是用在得到文件名的,可以试试os.path.basename活着os.path.split了
代码如下:
>>> import os.path >>> os.path.basename("c:\\test\\aa.txt") 'aa.txt' >>> os.path.split("c:\\test\\aa.txt") ('c:\\test', 'aa.txt') >>> os.path.split("c:\\test\\aa.txt")[-1] 'aa.txt' >>> os.path.basename("/home/test/aa.txt") 'aa.txt' >>> os.path.split("/home/test/aa.txt") ('/home/test', 'aa.txt') >>> os.path.basename("/home/test/aa.txt") 'aa.txt'
