Create Java apps using SQL Server on RHEL

In this section, you will get SQL Server 2017 on Red Hat Enterprise Linux (RHEL). After that you will install the necessary dependencies to create Java apps with SQL Server.

Step 1.1 Install SQL Server

Note: To ensure optimal performance of SQL Server, your machine should have at least 4 GB of memory.

1. Register the Microsoft Linux repository.

    curl https://packages.microsoft.com/config/rhel/7/mssql-server-2017.repo | sudo tee /etc/yum.repos.d/mssql-server-2017.repo
   

2. Install SQL Server.

    sudo yum update
    sudo yum install mssql-server
   

3. Setup your SQL Server.

    sudo /opt/mssql/bin/mssql-conf setup
   

    Microsoft(R) SQL Server(R) Setup
   
    To abort setup at anytime, press Ctrl-C.

You now have SQL Server running locally on your RHEL machine! Check out the next section to continue installing prerequisites.

Step 1.2 Install Java

If you already have Java installed on your machine, skip the next two steps. Install the Java Runtime Environment (JRE) using the following command.

  sudo yum install java-1.8.0-openjdk

Step 1.3 Install Maven

Maven can be used to help manage dependencies, build, test and run your Java project.

  sudo wget http://repos.fedorapeople.org/repos/dchen/apache-maven/epel-apache-maven.repo -O /etc/yum.repos.d/epel-apache-maven.repo
  sudo sed -i s/\$releasever/6/g /etc/yum.repos.d/epel-apache-maven.repo
  sudo yum install maven

Installed:
  maven.noarch 0:3.0.5-17.el7

Check that you have Maven properly installed by running the following command.

mvn -v

Apache Maven 3.0.5 (Red Hat 3.0.5-17)
Maven home: /usr/share/maven
Java version: 1.8.0_111, vendor: Oracle Corporation
Java home: /usr/lib/jvm/java-1.8.0-openjdk-1.8.0.111-2.b15.el7_3.x86_64/jre
Default locale: en_US, platform encoding: UTF-8
OS name: "linux", version: "3.10.0-327.36.3.el7.x86_64", arch: "amd64", family: "unix"

Note: If you’re using an older version of Java, such as 1.7, your results above may differ slightly. If you want to use an updated version of Java, please update your Java home variable.

You have successfully installed Java and Maven on RHEL. You now have everything you need to start writing your Java apps with SQL Server!
