[英]PowerShell MySQL Backup Script Error in Task Scheduler 0x00041301
I have created the following PowerShell script. 我创建了以下PowerShell脚本。
$root = 'C:\Backups\My Website\Database Dumps\'
$dateString = (Get-Date).ToString("yyyy-MM-dd")
$fileName = $dateString + "-MyWebsiteDbBackup.sql"
$backupFilePath = ($root + $fileName)
$command = ("mysqldump -u root wpdatabase > " + "`"$backupFilePath`"")
Write-Host $command
Invoke-Expression $command
Its function is supposed to be making a daily backup of a MySQL database for my WordPress website. 它的功能应该是对我的WordPress网站的MySQL数据库进行每日备份。
When I run the script in PowerShell ISE, it runs fine and the MySQL dump file is created with no problems. 当我在PowerShell ISE中运行脚本时,它运行良好,并且MySQL转储文件已创建成功。
However, in Task Scheduler, it was stuck on running with a code 0x00041301
. 但是,在Task Scheduler中,它停留在代码
0x00041301
上运行。
For the credentials, I am using the my.cnf
technique described here . 对于凭据,我使用此处描述的
my.cnf
技术。 And I've set the task to run whether a user is logged on or not. 而且我已将任务设置为无论用户是否登录都运行。
CODE UPDATE 代码更新
Based on vonPryz's answer. 基于vonPryz的答案。
$root = 'C:\Backups\My Website\Database Dumps\'
$dateString = (Get-Date).ToString("yyyy-MM-dd")
$fileName = $dateString + "-MyWebsiteDbBackup.sql"
$backupFilePath = ($root + $fileName + " 2>&1")
$command = ("mysqldump -u root wpdatabase > " + "`"$backupFilePath`"")
Write-Host $command
$output = Invoke-Expression $command
$output | Out-File C:\mysqlBackupScriptOutput.txt
This now give me an error saying illegal character in path
现在这给我一个错误,指出
illegal character in path
What am I doing wrong? 我究竟做错了什么?
Task Scheduler's code 0x00041301
means that the task is running. 任务计划程序的代码
0x00041301
表示任务正在运行。 This is likely to mean that mysqldump
is prompting for something. 这很可能意味着
mysqldump
正在提示某些内容。 Maybe a password or some confirmation dialog. 可能是密码或一些确认对话框。 Which user account is the task being run on?
任务在哪个用户帐户上运行?
In order to debug, you'd need to capture the process' output to see what's going on. 为了进行调试,您需要捕获流程的输出以查看发生了什么。 Try using
Tee-Object
to send a copy to a file. 尝试使用
Tee-Object
将副本发送到文件。
