一、背景

　　某数据库服务器为CentOS，想要监控Keepalived的VIP是否有问题，通过邮件进行报警，但这台机器不能上外网，现在只能在Windows下通过PowerShell来完成发邮件预警。

二、脚本详情

1.创建名为：ping-ip.ps1的PS脚本，代码如下所示：

# ping 192.168.1.51

Test-Connection 192.168.1.51 -Count 2

If ($? -ne "True"){

    Write-Host $address"连接失败"

    # send mail

    powershell.exe D:\ps\send-mail.ps1

}

Else {

    Write-Host $address"连接成功"

    $tcp.Close()

}

2.创建名为：send-mail.ps1的PS脚本，代码如下所示：

#mail server configuration

$smtpServer = "smtp.126.com"

$smtpUser = "bbs@126.com"

$smtpPassword = "mypsw"

#create the mail message

$mail = New-Object System.Net.Mail.MailMessage

#set the addresses

$MailAddress="bbs@126.com"

$MailtoAddress="1343xxx@139.com"

$mail.From = New-Object System.Net.Mail.MailAddress($MailAddress)

$mail.To.Add($MailtoAddress)

#set the content

$mail.Subject = "XX预警";

$mail.Priority  = "High"

$mail.Body = "VIP 失效了 $(Get-Date -Format 'M-d H:m:s')"

#$filename="file"

#$attachment = new-Object System.Net.Mail.Attachment($filename)

#$mail.Attachments.Add($attachment)

#send the message

$smtp = New-Object System.Net.Mail.SmtpClient -argumentList $smtpServer

$smtp.Credentials = New-Object System.Net.NetworkCredential -argumentList $smtpUser,$smtpPassword

$smtp.Send($mail)
