How to Install MS SQL Server on CentOS 7

Install MS SQL Server 2019 on CentOS 7

SQL Server is a Relational Database Management System (RDBMS) developed by Microsoft. Since it’s inception in 1989 from Sybase SQL Server, MS SQL Server was a platform dependent RDBMS and it only support different versions of Microsoft Windows. However, Microsoft haved added support for Linux platform in MS SQL Server 2017. Therefore, we can now install MS SQL Server 2017 (or later) on Windows, Linux and Docker platforms.

MS SQL Server 2017 is the stable version that is currently available to download. However, a MS SQL Server 2019 version is also available at their preview yum repository.

In this article, we will install MS SQL Server 2019 on CentOS 7 machine and then we will create a test database and a table using Transact-SQL (T-SQL).

This article only addresses the installation of MS SQL Server 2019 on CentOS 7 and some basic commands to give you an introduction of the environment. Therefore, if you are willing to know more about MS SQL Server and Transact-SQL (T-SQL) then you should read Learn Microsoft SQL Server Intuitively: Transact-SQL: The Solid Basics by zPL Concept.

To allow remote connections, we have to allow the MS SQL Server default port 1433/tcp in Linux Firewall.

# firewall-cmd --permanent --add-port=1433/tcp
success
# firewall-cmd --reload
success

 

Installing SQL Server Tools on CentOS 7:

We have configured a MS SQL Server 2019 and we can use SQL Server Management Studio (SSMS) on a windows based client to connect and use our database server.

However, we are also installing MS SQL Server command line utilities, so we can perform database administration tasks directly on our database server.

Download and install Microsoft yum repository to install SQL Server tools.

# curl -o /etc/yum.repos.d/msprod.repo https://packages.microsoft.com/config/rhel/7/prod.repo

Build yum cache for the newly added yum repository.

# yum makecache fast

Install SQL Server Tools using yum command.

# yum install -y mssql-tools

SQL Server tools has been installed in /opt/mssql/bin/ directory.

# ls /opt/mssql-tools/bin/
bcp  sqlcmd

Add this directory to PATH environment variable for accessibility and convenience.

# cat > /etc/profile.d/mssql-tools.sh << EOF
> #!/bin/bash
> export PATH=$PATH:/opt/mssql-tools/bin
> EOF

SQL Server tools has been installed on CentOS 7.

 

Using sqlcmd to execute Transact-SQL on MS SQL Server:

Connect to MS SQL Server instance using SA user and password.

# sqlcmd -S localhost -U SA -P 'Ahmer@1234'

You are now at the Transact-SQL (T-SQL) command prompt. Execute a query as follows:

1> select name from sys.databases;
2> go
name                                                                            
----------------------
master                                                                          
tempdb                                                                          
model                                                                           
msdb

Now, create a custom database on our MS SQL Server 2019 instance.

1> create database contacts;
2> go

Create a table in contacts database.

1> use contacts;
2> create table contacts_list
3> (contact_id char(6) primary key,
4> contact_name char(30));
5> go
Changed database context to 'contacts'.

Check our newly created table.

1> select name from sys.tables;
2> go
name                                                                            
-----------------------
contacts_list                                                                   

(1 rows affected)

Insert a row in contacts_list table.

1> use contacts;
2> insert into contacts_list
3> values
4> ('101','Ahmer Mansoor');
5> go
Changed database context to 'contacts'.

(1 rows affected)

You can execute any Transact-SQL (T-SQL) commands using sqlcmd. But we are not showing every command here in this article to keep it brief.

Exit from Transact-SQL (T-SQL) command prompt.

1> quit

We have successfully configured MS SQL Server 2019 on CentOS 7.

  1. anyway to enter yes to agree to the license without stopping my setup script?

    already tried without success:
    yes "YES" | rpm -i msodbcsql17-17.4.2.1-1.x86_64.rpm
    echo -e 'YES' | rpm -i msodbcsql17-17.4.2.1-1.x86_64.rpm
