In this article, we will learn how to install and configure MS SQL on CentOS 7. Microsoft recently announced their plans to release MS SQL for Linux. Specifically, beta versions are available for Red Hat Enterprise Linux, CentOS, and Ubuntu, but only for 64-bit versions.
Since no MS SQL is available in the default CentOS repository, we need to add the details of the MS SQL repository to the local yum repository.
In order to install MS SQL Server using the command line, we need to add the repository to the local yum repository.
# curl https://packages.microsoft.com/config/rhel/7/mssql-server.repo > /etc/yum.repos.d/mssql-server.repo % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 100 220 100 220 0 0 257 0 --:--:-- --:--:-- --:--:-- 257
After updating the repository, we will run the following command to install the MS-SQL server
# yum update # yum install -y mssql-server … … Resolving Dependencies --> Running transaction check ---> Package mssql-server.x86_64 0:14.0.1.246-6 will be installed --> Processing Dependency: bzip2 for package: mssql-server-14.0.1.246-6.x86_64 --> Processing Dependency: gdb for package: mssql-server-14.0.1.246-6.x86_64 --> Running transaction check ---> Package bzip2.x86_64 0:1.0.6-13.el7 will be installed ---> Package gdb.x86_64 0:7.6.1-80.el7 will be installed --> Finished Dependency Resolution Dependencies Resolved ================================================================================ Package Arch Version Repository Size ================================================================================ Installing: mssql-server x86_64 14.0.1.246-6 packages-microsoft-com-mssql-server 138 M Installing for dependencies: bzip2 x86_64 1.0.6-13.el7 base 52 k gdb x86_64 7.6.1-80.el7 base 2.4 M Transaction Summary ================================================================================ Install 1 Package (+2 Dependent packages) … … +-------------------------------------------------------------------+ | Please run /opt/mssql/bin/sqlservr-setup to complete the setup of | | Microsoft(R) SQL Server(R). | +-------------------------------------------------------------------+ Verifying : mssql-server-14.0.1.246-6.x86_64 1/3 Verifying : gdb-7.6.1-80.el7.x86_64 2/3 Verifying : bzip2-1.0.6-13.el7.x86_64 3/3 Installed: mssql-server.x86_64 0:14.0.1.246-6 Dependency Installed: bzip2.x86_64 0:1.0.6-13.el7 gdb.x86_64 0:7.6.1-80.el7 Complete!
Once the installation is complete, we will run sqlservr- setup script to set the SA password; we need to provide a strong password for the SA account (at least 8 characters, lowercase and uppercase letters and numbers from 1 to 10 or any non-alphanumeric characters)
# sudo /opt/mssql/bin/sqlservr-setup Microsoft(R) SQL Server(R) Setup You can abort setup at any time by pressing Ctrl-C. Start this program with the --help option for information about running it in unattended mode. Please enter a password for the system administrator (SA) account: Please confirm the password for the system administrator (SA) account: Setting a password for the system administrator (SA) account Do you wish to start the SQL Server service now? [y/n]: Y Do you wish to enable SQL Server to start on boot? [y/n]: y Created symlink from /etc/systemd/system/multi-user.target.wants/mssql-server.service to /usr/lib/systemd/system/mssql-server.service. Created symlink from /etc/systemd/system/multi-user.target.wants/mssql-server-telemetry.service to /usr/lib/systemd/system/mssql-server-telemetry.service. Setup completed successfully.
After configuration is complete , we will restart the MS SQL service and use the following command to view the status of the service:
Restart the service
# systemctl start mssql-server
View the status of the service
# systemctl status mssql-server mssql-server.service - Microsoft(R) SQL Server(R) Database EngineLoaded: loaded (/usr/lib/systemd/system/mssql-server.service; enabled; vendor preset: disabled) Active: active (running) since Fri 2016-12-02 15:52:33 IST; 5min ago Main PID: 2299 (sqlservr) CGroup: /system.slice/mssql-server.service ├─2299 /opt/mssql/bin/sqlservr └─2307 /opt/mssql/bin/sqlservr Dec 02 15:52:37 localhost.localdomain sqlservr[2299]: 2016-12-02 10:22:37.31 spid17s....

We need to open the firewall settings so that MS SQL can be accessed. The following is the command to open the firewall
# sudo firewall-cmd --zone=public --add-port=1433/tcp --permanent # sudo firewall-cmd –reload
We need to download the Microsoft warehouse.
# curl https://packages.microsoft.com/config/rhel/7/prod.repo > /etc/yum.repos.d/msprod.repo % Total % Received % Xferd Average Speed Time Time Time Current Dload Upload Total Spent Left Speed 0 0 0 0 0 0 0 0 --:--:-- --:--:-- --:--:-- 0 100 193 100 193 0 0 213 0 --:--:-- --:--:-- --:--:-- 213
Once the repository is installed on the local machine, we can install MS SQL tools using the following command:
# yum install mssql-tools Loaded plugins: fastestmirror packages-microsoft-com-prod | 2.9 kB 00:00:00 packages-microsoft-com-prod/primary_db | 4.6 kB 00:00:00 Loading mirror speeds from cached hostfile * base: mirrors.digipower.vn * extras: mirror.digistar.vn * updates: mirror.digistar.vn Resolving Dependencies ======================================================================================== Package Arch Version Repository Size ======================================================================================== Installing: mssql-tools x86_64 14.0.1.246-1 packages-microsoft-com-prod 249 k Installing for dependencies: libtool-ltdl x86_64 2.4.2-21.el7_2 updates 49 k msodbcsql x86_64 13.0.1.0-1 packages-microsoft-com-prod 3.8 M unixODBC-utf16 x86_64 2.3.1-1 packages-microsoft-com-prod 329 k Transaction Summary ======================================================================================== Install 1 Package (+3 Dependent packages) Total download size: 4.5 M Installed size: 4.5 M Is this ok [y/d/N]: ^CN Exiting on user command Your transaction was saved, rerun it with: yum load-transaction /tmp/yum_save_tx.2016-12-02.17-18.RpEVqg.yumtx Do you accept the license terms?

on the computer After installing the tool, we will test the following commands and general syntax to connect to MS SQL Server.
Syntax
# sqlcmd –S IP-ADDRESS –U SA –P ‘CREATE DATABASE TEST1; 2>GO; 3>quit
