问题 I've got a problem trying to build a easy backup/upgrade database script. The error is in the mysqldump call using subprocess: cmdL = ["mysqldump", "--user=" + db_user, "--password=" + db_pass, domaindb + "|", "gzip", ">", databases_path + "/" + domaindb + ".sql.gz"] print "%s: backup database %s \n\t[%s]" % (domain, domaindb, ' '.join(cmdL)) total_log.write("%s: backup database %s \n\t[%s] \n" % (domain, domaindb, ' '.join(cmdL))) p = subprocess.Popen(cmdL, stdout=subprocess.PIPE, stderr

Automate MySQLdump to local computer (Windows)

由 ↘锁芯ラ 提交于 2019-12-13 11:35:06
问题 I'd like to automate a mysqldump to my computer from a remote host, and I cannot figure out how to do it. I suppose that I should run a mysqldump through an SSH tunnel, but this becomes complicated by the fact that my local computer is a Windows XP machine. I'm using putty to open a tunnel like so: putty -load "[my saved session]" -L [localport]:localhost:3306 -N Note: I can't just connect to the mysql server remotely. 回答1: Instead of PuTTY, download the command line version plink.exe . Then

数据备份的中要性 在生产环境中，数据的安全性是至关重要的，任何数据的丢失都可能产生严重的后果 造成数据丢失的原因 程序错误 人为错误 计算机失败 磁盘失败 灾难（如起火、地震）和偷窃 数据库备份的分类 从物理与逻辑的角度，备份可分为 物理备份：对数据库操作系统的物理文件（如数据文件、日志文件等）的备份 物理备份又可以分为脱机备份（冷备份）和联机备份（热备份） 冷备份：是关闭数据库的时候进行的 热备份：数据库处于运行状态，这种备份方法依赖于数据库的日志文件 逻辑备份：对数据库逻辑组件（如表等数据库对象）的备份 从数据库的备份策略角度，备份可分为 完全备份：每次对数据进行完整的备份 差异备份：备份那些自从上次完全备份之后被修改过的文件 增量备份：只有那些在上次完全备份或者增量备份后修改的文件才会被备份 MySQL完全备份 完全备份是对整个数据库的备份、数据库结构和文件结构的备份 完全备份保存的是备份完成时刻的数据库 完全备份是增量备份的基础 完全备份的优点 备份与恢复操作简单方便 完全备份的缺点 数据存在大量的重复 占用大量的备份空间 备份与恢复时间长 mysqldump备份数据库 MySQL数据库的备份可以采用多种方式 直接打包数据库文件夹，如/usr/local/mysql/data 使用专用备份工具 mysqldump mysqldump命令 MySQL自带的备份工具

mysqldump: Error 2020: Got packet bigger than 'max_allowed_packet' bytes when dumping table

问题 mysqldump: Error 2020: Got packet bigger than 'max_allowed_packet' bytes when dumping table happens, when I do a mysqldump -u root -p database >dumpfile.sql I increased max_allowed_packet to the max value already (1073741824) to no avail. How come that one cannot dump a database with mysqls on board means? Cause may be a longblob in a data row/column which may be maximum size of 4 GB (4294967295 bytes). Could it be the network transport being used? Would there be another transport? 回答1: Use

The XML file is laid out like this: <mysqldump> <database name="export"> <table_structure name="export_rental_2006_property"> <field Field="id" Type="bigint(20)" Null="NO" Key="" Default=""
