Introduction to MS SQL Server Ubuntu
MS SQL Server is a relational database management system developed by Microsoft. It is designed to store, manipulate, and retrieve data as requested by other software applications. MS SQL Server can be installed on different operating systems, including Ubuntu, which is a popular Linux distribution favored by many developers and system administrators.
Ubuntu is a free and open-source operating system that is known for its stability and security. It is also compatible with many software applications, including MS SQL Server. Installing MS SQL Server on Ubuntu can provide many benefits, such as cost savings, flexibility, and ease of management.
Why Use MS SQL Server Ubuntu?
Many organizations choose to use MS SQL Server Ubuntu because of the following reasons:
| Reasons | Description |
|---|---|
| Cost-effective | Ubuntu is a free and open-source operating system, which means that organizations can save money on licensing fees. |
| Stable and secure | Ubuntu has a reputation for being a stable and secure operating system that is less vulnerable to cyber attacks compared to other operating systems. |
| Flexible | Ubuntu can be easily customized to meet the specific needs of an organization. It also has a strong community support that can provide assistance on various issues. |
Installation and Configuration
Installing MS SQL Server on Ubuntu requires a few steps, but the process is straightforward and can be completed within a few minutes. Here are the steps to install MS SQL Server on Ubuntu:
Step 1: Add the Microsoft SQL Server repository
First, you need to add the Microsoft SQL Server repository to Ubuntu by running the following command:
wget -qO- https://packages.microsoft.com/keys/microsoft.asc | sudo apt-key add -
sudo add-apt-repository "$(wget -qO- https://packages.microsoft.com/config/ubuntu/16.04/mssql-server-2017.list)"This command will add the Microsoft GPG key to your system and create a new repository file that contains the necessary information to install MS SQL Server.
Step 2: Install MS SQL Server
Next, you need to install MS SQL Server by running the following command:
sudo apt-get update
sudo apt-get install -y mssql-serverThis command will update the system package list and install MS SQL Server. During the installation process, you will be prompted to set the system administrator (SA) password.
Step 3: Configure MS SQL Server
After installing MS SQL Server, you need to configure it by running the following command:
sudo /opt/mssql/bin/mssql-conf setupThis command will launch the MS SQL Server configuration script, which will guide you through the configuration process. You will be prompted to specify several settings, such as the SA password, the TCP port, and the language.
Step 4: Verify MS SQL Server Status
After installing and configuring MS SQL Server, you need to verify its status by running the following command:
systemctl status mssql-server --no-pagerThis command will display the current status of MS SQL Server, including whether it is running or stopped.
Security and Backup
Security and backup are crucial aspects of managing an MS SQL Server Ubuntu. Here are some tips on how to secure and backup your MS SQL Server Ubuntu:
Tip 1: Enable SSL Encryption
Enabling SSL encryption can help secure the communication between the MS SQL Server and the client applications. Here are the steps to enable SSL encryption:
- Generate a self-signed certificate by running the following command:
openssl req -x509 -newkey rsa:4096 -keyout /tmp/sql.key -out /tmp/sql.crt -days 365 -nodes - Copy the certificate files to the MS SQL Server certificate folder:
sudo cp /tmp/sql.crt /var/opt/mssql/data/
sudo cp /tmp/sql.key /var/opt/mssql/data/ - Modify the MS SQL Server configuration file (/var/opt/mssql/mssql.conf) to enable SSL encryption:
sudo nano /var/opt/mssql/mssql.conf
Uncomment the following lines:
forceprotocolencryption = 1
servercertificate = /var/opt/mssql/data/sql.crt
privatekeyfile = /var/opt/mssql/data/sql.key - Restart the MS SQL Server service:
sudo systemctl restart mssql-server - Verify SSL encryption by running the following command:
openssl s_client -connect localhost:1433 -tls1 -no_ssl3 -ign_eof
Tip 2: Use Strong Passwords
Using strong passwords can help prevent unauthorized access to your MS SQL Server Ubuntu. Make sure to use passwords that contain a mix of uppercase and lowercase letters, numbers, and special characters. Also, avoid using easily guessable passwords, such as “password” or “123456”.
Tip 3: Implement Regular Backup
Regular backup can help protect your data against accidental deletion or system failure. Here are the steps to implement regular backup:
- Create a backup folder:
sudo mkdir /var/opt/mssql/backup - Grant permission to the backup folder:
sudo chmod 777 /var/opt/mssql/backup - Create a backup schedule by adding the following line to the crontab file:
sudo crontab -e
0 1 * * * /opt/mssql-tools/bin/sqlcmd -S localhost -U sa -P <sa_password> -Q "BACKUP DATABASE <database_name> TO DISK='/var/opt/mssql/backup/<database_name>_$(date +\%Y\%m\%d\%H\%M\%S).bak'"
This command will create a backup of the specified database at 1:00 AM every day.
Optimizing Performance
Optimizing performance is essential for achieving faster response time and better user experience. Here are some tips on how to optimize your MS SQL Server Ubuntu:
Tip 1: Use Indexes
Indexes can help speed up the query execution time by allowing the MS SQL Server to retrieve data more efficiently. Make sure to use indexes on columns that are frequently used in queries.
Tip 2: Monitor Resource Usage
Monitoring resource usage can help identify bottlenecks and ensure that the MS SQL Server has enough resources to operate efficiently. Use tools like the Performance Monitor to monitor CPU, memory, disk, and network usage.
Tip 3: Clean Up Old Data
Cleaning up old data can help reduce the size of your database and improve the query performance. Use the DELETE statement to remove data that is no longer needed.
