Oracle帮您准确洞察各个物流环节

前提:具有ssh登陆权限

工作步骤:

下载软件putty,设置ssh 登陆选项

登陆后,进入自己的主页目录*(通过ftp可以访问到)

执行MySQLdump命令可执行数据库备份,而MySQLrestore命令则恢复数据库。

格式:

pXXXXXXX@kundenserver:~ > MySQLdump -hdbXX.puretec.de -upXXXXXXX -p******** dbXXXXXXX > dbXXXXXXXX.sql

pXXXXXXX@kundenserver:~ > MySQL -hdbXX.puretec.de -upXXXXXXX -p******** dbXXXXXXX

执行MySQLdump后,会在当前所在目录生成一个MySQL数据库备份文件(大小和数据库大小相当)

通过ftp即可下载备份的数据库文件包

恢复数据库工作与以上两部相反

你也可以写一个php脚本,来完成以上操作:
