Downloading and installing WildFly

In this recipe, we will learn how to get and install WildFly. As always, in the open source world you can do the same thing in different ways. WildFly can be installed using your preferred software manager or by downloading the bundle provided by the http://wildfly.org site. We will choose the second way, as per the JDK.

Getting ready

Just open your favorite browser and point it to http://wildfly.org/downloads/. You should see a page similar to the following screenshot:

WildFly's download page

At the time of writing this book, the latest WildFly was version 9.0.0.Beta2. The final version is now available and in use.

Now, download the latest version into the WFC folder.

How to do it…

1. Once the download is complete, open a terminal and extract its contents into the WFC folder, executing the following commands:

   $ cd ~/WFC && tar zx wildfly-9.0.0.Beta2.tar.gz
   

   The preceding command will first point to our WildFly Cookbook folder; it will then extract the WildFly archive from it. Listing our WFC folder, we should find the newly created WildFly' folder named wildfly-9.0.0.Beta2.

2. To better remember and handle WildFly's installation directory, rename it wildfly, as follows:

   $ cd ~/WFC && mv wildfly-9.0.0.Beta2 wildfly
   

   By the way, WildFly can be also installed using the traditional YUM, Fedora's software manager.

   Note

   In a production environment, you will not place the WildFly installation directory into the home folder of a specific user. Rather, you will be placing it into different paths, relative to the context you are working in.

3. Now we need to create the JBOSS_HOME environment variable, which is used by WildFly itself as base directory when it starts up (probably in future releases, this will be updated to WILDFLY_HOME). We will also create the WILDFLY_HOME environment variable, which we will use throughout the whole book to reference WildFly's installation directory. Thus, open the .bash_profile file, placed in your home folder, with your favorite text editor and add the following directives:

   export JBOSS_HOME=~/WFC/wildfly
   export WILDFLY_HOME=$JBOSS_HOME

4. For the changes to take effect, you can either log out and log back in, or just issue the following command:

   $ source ~/.bash_profile
   

If you followed the first two recipes carefully, your .bash_profile file should look like the following image:
