Nessuna differenza per SQL Server: si fa tutto dalla console

18. Install SQL Server
Ubuntu:
# Import the public repository GPG keys:
curl | sudo apt-key add –
# Register the Microsoft SQL Server Ubuntu repository:
sudo add-apt-repository "$(curl
# Install SQL Server:
sudo apt-get update
sudo apt-get install -y mssql-server
# Config
sudo /opt/mssql/bin/mssql-conf setup
# Check
systemctl status mssql-server

19. Install SQL Server Agent
# Ubuntu
sudo apt-get update
sudo apt-get install mssql-server-agent
sudo systemctl restart mssql-server

20. Install SQL Server Full-Text Search
# Ubuntu
sudo apt-get update
sudo apt-get install -y mssql-server-fts
Il Semantic Search DB è all’interno di “/opt/mssql/misc/semanticsdb.bak”. E’ sufficiente un restore.

21. Install SQL Server Integration Server
# Ubuntu
sudo apt-get update
sudo apt-get install -y mssql-server-is
# Config
sudo /opt/ssis/bin/ssis-conf setup
# Path
export PATH=/opt/ssis/bin:$PATH
dtexec /F <package name> /DE <protection password>

22. Upgrade
Repository:
Cumulative Updates (CU): CU + Bug Fix + Improvements
GDR: Critical Fix + Security Updates
Path:
GDR -> CU
CU -> GDR
# Verifica l’impostazione corrente
sudo cat /etc/apt/sources.list
# Rimuove la configurazione corrente
sudo add-apt-repository -r 'deb [arch=amd64] xenial main’
# Importa la chiave pubblica del repository
sudo curl | sudo apt-key add –
# Imposta il Nuovo repository (CU in questo caso)
sudo add-apt-repository "$(curl && sudo apt-get update

23. Upgrade Verificare se necessita upgrade Nel caso
sudo apt-get --just-print upgrade
sudo apt-get update
sudo apt-get install mssql-server

24. Disponibili su Azure

25. Package disponibili su AZ Gallery VM

26. Best practice (file location)
Impostare Data & Log directory
TempDB location
Backup location
sudo chown mssql [new path]
sudo chgrp mssql [new path]
sudo /opt/mssql/bin/mssql-conf set filelocation.defaultdatadir [new path]
sudo /opt/mssql/bin/mssql-conf set filelocation.defaultlogdir [new path]
sudo systemctl restart mssql-server
sudo chown mssql [new path]
sudo chgrp mssql [new path]
sudo mv /var/opt/mssql/data/tempdb.mdf [new path]
sudo mv /var/opt/mssql/data/templog.mdf [new path]
sudo systemctl restart mssql-server
sudo chown mssql [new path]
sudo chgrp mssql [new path]
sudo /opt/mssql/bin/mssql-conf set filelocation.defaultbackupdir [new path]
sudo systemctl restart mssql-server

27. Best practice (other settings)
Memory Limit
TempDB Config
sudo /opt/mssql/bin/mssql-conf set memory.memorylimitmb [limit]
sudo systemctl restart mssql-server
USE [master] GO
ALTER DATABASE [tempdb] ADD FILE ( NAME = N'tempdev_cpu2', FILENAME = N'/var/opt/mssql/data/tempdev_cpu2.ndf' , SIZE = 8192KB , FILEGROWTH = 65536KB )
ALTER DATABASE [tempdb] ADD FILE ( NAME = N'tempdev_cpu3', FILENAME = N'/var/opt/mssql/data/tempdev_cpu3.ndf' , SIZE = 8192KB , FILEGROWTH = 65536KB )
ALTER DATABASE [tempdb] ADD FILE ( NAME = N'tempdev_cpu4', FILENAME = N'/var/opt/mssql/data/tempdev_cpu4.ndf' , SIZE = 8192KB , FILEGROWTH = 65536KB )
