Install Microsoft SQL Server 2017 on Fedora 29/CentOS 7

To install MS SQL server 2017 on Fedora 29/CentOS , you need to create the MS SQL repository on your Fedora 29/CentOS 7 server since mssql-server package is not available on the default repos.

Create MS SQL repository

Run the command below to install Fedora/CentOS MS SQL repo.

wget -O /etc/yum.repos.d/mssql-server-2017.repo https://packages.microsoft.com/config/rhel/7/mssql-server-2017.repo

Once the MS SQL repository is created, install MS SQL server.

On CentOS 7, run;

yum install mssql-server

On Fedora 29, run;

dnf install mssql-server

You can however use yum on both.

Setup MS SQL server

Once the installation is done, run the setup script, /opt/mssql/bin/sqlservr-setup, to setup MS SQL server system administrator (SA) password and choose your MS SQL edition. Note that the Evaluation, Developer and Express editions are free-licensed. In this case, we are going to choose the Developer Edition. All the limitations have been removed on the Developer edition hence it is fully functional.

/opt/mssql/bin/mssql-conf setup

Choose an edition of SQL Server:
  1) Evaluation (free, no production use rights, 180-day limit)
  2) Developer (free, no production use rights)
  3) Express (free)
  4) Web (PAID)

The default port for MS SQL is 1433/TCP.

ss -altnp | grep 1433
LISTEN     0      128          *:1433                     *:*                   users:(("sqlservr",pid=3951,fd=133))

Configure firewalld Firewall to allow access to MS SQL server.

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

MS SQL has been successfully installed on Fedora 29/CentOS 7 server. In order to manage the database tasks, you need to install MS SQL server command line management tools such as bcp and sqlcmd. These tools are not available on the default Fedora/CentOS repos. Hence create the repository as shown below;

wget -O /etc/yum.repos.d/mssql-tools.repo https://packages.microsoft.com/config/rhel/7/prod.repo

Install MS SQL command line tools

yum install -y mssql-tools unixODBC-devel

The sqlcmd command is installed to /opt/mssql-tools/bin/. To ensure that the command is available on your default PATH environment, create a symbolic to /usr/bin/ as shown below;

ln -s /opt/mssql-tools/bin/sqlcmd /usr/bin/

The sqlcmd is now available under /usr/bin/.

which sqlcmd
/usr/bin/sqlcmd

Connect locally to you MS SQL server as SA and create a sample database;

sqlcmd -S localhost -U SA
Password: <SA password created above>

This takes you to sqlcmd prompt, 1>. Note that an sql statement is not executed until you enter GO.

1> CREATE DATABASE testdbA
2> GO
1>

Verify the test database creation.

1> select name from sys.databases
2> go
