【脚本分享】- Windows下利用Powershell进行MySQL数据库备份-CFANZ编程社区

环境准备

测试环境: Server 2008 R2

所需软件:

 - MySQLdump.exe  
 - msvcp120.dll  x64/x86
 - msvcr120.dll  x64/x86
 - powershell
 - 7z

设置PowerShell策略:

PS C:\Users\Administrator> Set-ExecutionPolicy -ExecutionPolicy Unrestricted -Scope LocalMachine

执行策略更改
执行策略可以防止您执行不信任的脚本。更改执行策略可能会使您面临 about_Execution_Policies
帮助主题中所述的安全风险。是否要更改执行策略?
[Y] 是(Y)  [N] 否(N)  [S] 挂起(S)  [?] 帮助 (默认值为“Y”): Y

regsvr32 msvcr120.dll
regsvr32 msvcp120.dll

数据库相关信息查看:

# 1.版本
SELECT @@version;

# 2.指定数据库的表与表数据行统计查看
select table_name,table_rows from information_schema.tables where TABLE_SCHEMA = 'authcenter' order by table_rows desc;
