Azure SQL Linux VM – configuring SQL, installing pwsh and connecting and interacting with dbatools

Posted on by

In my posts about using Azure Devops to build Azure resources with Terraform, I built a Linux SQL VM. I used the Terrafrom in this GitHub repository and created this

Connecting with MobaXterm

I had set the Network security rules to accept connections only from my static IP using variables in the Build Pipeline. I use MobaXterm as my SSH client. Its a free download. I click on sessions

Choose a SSH session and fill in the remote host address from the portal

fill in the password and

Configuring SQL

The next task is to configure the SQL installation. Following the instructions on the Microsoft docs site I run

sudo systemctl stop mssql-server
sudo /opt/mssql/bin/mssql-conf set-sa-password

enter the sa password and

Now to start SQL

sudo systemctl start mssql-server

Installing pwsh

Installing PowerShell Core (pwsh) is easy with snap 

sudo snap install powershell --classic

A couple of minutes of downloads and install

and pwsh is ready for use

Installing dbatools

To install dbatools from the Powershell Gallery simply run

Install-Module dbatools -Scope CurrentUser

This will prompt you to allow installing from an untrusted repository

and dbatools is ready to go

#Set a credential
$cred = Get-Credential
# Show the databases on the local instance
Get-DbaDatabase -SqlInstance localhost -SqlCredential $cred

Connecting with Azure Data Studio

I can also connect with Azure Data Studio

and connect

Just a quick little post explaining what I did 🙂

Happy Linuxing!

Getting the SQL Version from a backup using dbatools ………. on PowerShell Core

Posted on by

Following an upgrade to SQL Server the backup share had a number of backups, some from the old version and some from the newer version. I was asked if I had a script to be able to get the SQL Version from the backup file from all of the files in the backup share.

With dbatools this was easy to accomplish with Read-DbaBackuoHeader

$backupshare = "$share\keep"
$Instance = "SQL0\Mirror"

$information = foreach ($BackupFile in (Get-ChildItem $backupshare)) {
    $FileName = @{Name = 'FileName'; Expression = {$BackupFile.Name}}
    Read-DbaBackupHeader -SqlInstance $Instance -Path $BackupFile.FullName | Select-Object  $FileName, DatabaseName , CompatibilityLevel, SqlVersion
}
$information | Format-Table

You can get more information about the backup using Read-DbaBackupHeader and as it is PowerShell it is easy to put this information into any format that you wish, maybe into a database with Write-DbaDataTable

Support for PowerShell Core in dbatools is coming along very nicely. Following some hard work by the dbatools team and some PowerShell Community members like Mathias Jessen it is now possible to run a large number of dbatools commands in PowerShell Core running on Windows. There is still a little bit of work to do to get it working on Linux and Mac but I hear the team are working hard on that.

So the code example you see above was running on Windows 10 using PowerShell 6.1.1 the current latest stable release. This is excellent news and congratulations to all those working hard to make this work
