用python生成一个导出数据库的bat脚本文件

环境: python3.x def getExportDbSql(db, index): # 获取导出一个数据库实例的sql语句 sql = ‘mysqldump -u%s -p%s -h%s -P%d --default-character-set=utf8 --databases mu_ins_s%s > %s.s%d.mu_ins_%d.sql‘ %(db[‘user‘], db[‘pwd‘], db[‘host‘], db[‘port‘], index, db[‘server‘], index, index) return sql def createDbBackupFile(fname, dbList): # 生成数据库导出的语句保存到文件 if not fname or not dbList: return False f = open(fname, ‘w‘) if f: f.write(‘echo @off\n\n‘) for db in dbList: for index in db[‘indexList‘]: f.write(‘REM %s.s%d\n‘ %(db[‘server‘], index)) f.write(‘%s\n\n‘ %getExportDbSql(db, index)) f.write(‘\n‘) f.close() return True return False def initDb(user, pwd, host, port, server_name, indexList): # 生成db字典对象并返回 db = {} db[‘user‘] = user db[‘pwd‘] = pwd db[‘host‘] = host db[‘port‘] = port db[‘server‘] = server_name db[‘indexList‘] = indexList return db def displayDb(db): print(‘user =‘, db[‘user‘]) print(‘pwd =‘, db[‘pwd‘]) print(‘host =‘, db[‘host‘]) print(‘port =‘, db[‘port‘]) print(‘server =‘, db[‘server‘]) print(‘indexList =‘, db[‘indexList‘]) print(‘\n‘) def displayList(list): for item in list: displayDb(item) if __name__ == ‘__main__‘: db1 = initDb(‘root‘, ‘123456‘, ‘127.0.0.1‘, 3306, ‘th1‘, [10000, 1, 3]) db2 = initDb(‘root‘, ‘123456‘, ‘127.0.0.1‘, 3306, ‘th2‘, [10000, 1]) dbList = [] dbList.append(db1) dbList.append(db2) #displayList(dbList) createDbBackupFile(‘export00.bat‘, dbList) # 何问起 hovertree.com
