Install Microsoft SQL Server 2019 on CentOS 7

SQL Server runs on Linux starting with SQL Server 2017. This SQL Server is the same SQL Server database engine running on Microsoft Operating systems, with many similar features and services.

This guide will take you through the steps to install Microsoft SQL Server 2019 on CentOS 7 | Fedora 36/35/34/33/32 Linux system. As of this writing, SQL Server 2019 is available for Production use on Ubuntu / CentOS and RHEL Linux.

Step 1: Install Microsoft SQL Server 2019 on CentOS 7 / Fedora

Microsoft SQL Server 2019 is available for the general use. Add the repository to your CentOS 7 / Fedora by running the following commands on your terminal.

sudo curl -o /etc/yum.repos.d/mssql-server.repo https://packages.microsoft.com/config/rhel/7/mssql-server-2019.repo

This will download  SQL Server 2019 repository to 

/etc/yum.repos.d/mssql-server.repo

Update your system cache:

### CentOS 7 ###
sudo yum makecache

### Fedora ###
sudo dnf makecache

Then install SQL server 2019 on CentOS 7:

sudo yum install -y mssql-server

  3) Express (free)
  4) Web (PAID)
  5) Standard (PAID)
  6) Enterprise (PAID)

Setup has completed successfully. SQL Server is now starting.

Step 3: Install SQL Server command-line tools

Then install mssql-tools with the unixODBC developer package. Add the repository containing required packages using the next command:

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

echo 'export PATH=$PATH:/opt/mssql/bin:/opt/mssql-tools/bin' | sudo tee /etc/profile.d/mssql.sh

Source the file to start using MS SQL executable binaries in your current shell session:

source /etc/profile.d/mssql.sh

If you have an active Firewalld service, allow SQL Server ports for remote hosts to connect:

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

Step 5: Test SQL Server
