Formerly known as JBoss, WildFly is open-source and aims to provide the fastest Java runtime environment possible. With features such as subsystem blocks made to be easily added and removed, centralized configurations between environments, support for the latest Java enterprise standards, and much more, WildFly is an excellent choice for an application server.<!--more--><\/p>\n<p>In this tutorial, we will cover the full installation process for installing WildFly 14 onto your CentOS 7 machine. However, in order to complete this tutorial, your current setup has some requirements that need to be met. You must have a <a href=\"https:\/\/www.rosehosting.com\/vps-hosting.html\">VPS<\/a> or a machine running CentOS 7, a user with root access, and a static public IP address set up for your server.<\/p>\n<div id=\"ez-toc-container\" class=\"ez-toc-v2_0_65 counter-hierarchy ez-toc-counter ez-toc-transparent ez-toc-container-direction\">\n<p class=\"ez-toc-title\">Table of Contents<\/p>\n<label for=\"ez-toc-cssicon-toggle-item-6630341e3b2f9\" class=\"ez-toc-cssicon-toggle-label\"><span class=\"ez-toc-cssicon\"><span class=\"eztoc-hide\" style=\"display:none;\">Toggle<\/span><span class=\"ez-toc-icon-toggle-span\"><svg style=\"fill: #999;color:#999\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" class=\"list-377408\" width=\"20px\" height=\"20px\" viewBox=\"0 0 24 24\" fill=\"none\"><path d=\"M6 6H4v2h2V6zm14 0H8v2h12V6zM4 11h2v2H4v-2zm16 0H8v2h12v-2zM4 16h2v2H4v-2zm16 0H8v2h12v-2z\" fill=\"currentColor\"><\/path><\/svg><svg style=\"fill: #999;color:#999\" class=\"arrow-unsorted-368013\" xmlns=\"http:\/\/www.w3.org\/2000\/svg\" width=\"10px\" height=\"10px\" viewBox=\"0 0 24 24\" version=\"1.2\" baseProfile=\"tiny\"><path d=\"M18.2 9.3l-6.2-6.3-6.2 6.3c-.2.2-.3.4-.3.7s.1.5.3.7c.2.2.4.3.7.3h11c.3 0 .5-.1.7-.3.2-.2.3-.5.3-.7s-.1-.5-.3-.7zM5.8 14.7l6.2 6.3 6.2-6.3c.2-.2.3-.5.3-.7s-.1-.5-.3-.7c-.2-.2-.4-.3-.7-.3h-11c-.3 0-.5.1-.7.3-.2.2-.3.5-.3.7s.1.5.3.7z\"\/><\/svg><\/span><\/span><\/label><input type=\"checkbox\"  id=\"ez-toc-cssicon-toggle-item-6630341e3b2f9\"  aria-label=\"Toggle\" \/><nav><ul class='ez-toc-list ez-toc-list-level-1 ' ><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-1\" href=\"https:\/\/www.rosehosting.com\/blog\/how-to-install-wildfly-14-on-centos-7\/#Step-1-Installing-Java\" title=\"Step 1: Installing Java\">Step 1: Installing Java<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-2\" href=\"https:\/\/www.rosehosting.com\/blog\/how-to-install-wildfly-14-on-centos-7\/#Step-2-Installing-WildFly\" title=\"Step 2: Installing WildFly\">Step 2: Installing WildFly<\/a><\/li><li class='ez-toc-page-1 ez-toc-heading-level-2'><a class=\"ez-toc-link ez-toc-heading-3\" href=\"https:\/\/www.rosehosting.com\/blog\/how-to-install-wildfly-14-on-centos-7\/#Step-3-Creating-a-User\" title=\"Step 3: Creating a User\">Step 3: Creating a User<\/a><\/li><\/ul><\/nav><\/div>\n<h2><span class=\"ez-toc-section\" id=\"Step-1-Installing-Java\"><\/span>Step 1: Installing Java<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In order for WildFly to work, it needs the Java Developer Kit, or JDK. Install JDK version 10.0.2 (the latest version at the time of writing) onto your system by downloading the JDK to your server from Oracle&#8217;s site. Open a terminal on your CentOS VPS\/machine and execute these two commands:<\/p>\n<pre>cd \/opt\r\nsudo wget --no-cookies --no-check-certificate --header \"Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie\" \"http:\/\/download.oracle.com\/otn-pub\/java\/jdk\/10.0.2+13\/19aef61b38124481863b1413dce1855f\/jdk-10.0.2_linux-x64_bin.tar.gz\"<\/pre>\n<p>You then need to extract the downloaded tarball using the &#8216;tar&#8217; command:<\/p>\n<pre>tar -zxvf jdk-10.0.2_linux-x64_bin.tar.gz<\/pre>\n<p>(You can now delete the downloaded tarball)<\/p>\n<p>Once this has been downloaded and extracted onto your machine, we can use &#8216;alternatives&#8217; to set up the JDK onto your system without interfering with already existing installs (if present). Use these commands to set up this new version of Java:<\/p>\n<pre>sudo alternatives --install \/usr\/bin\/java java \/opt\/jdk-10.0.2\/bin\/java 2\r\nsudo alternatives --config java<\/pre>\n<p>Once this is done, you can then set the &#8216;java&#8217; and &#8216;javac&#8217; locations using the &#8216;alternatives&#8217; command.<\/p>\n<pre>sudo alternatives --install \/usr\/bin\/jar jar \/opt\/jdk-10.0.2\/bin\/jar 2\r\nsudo alternatives --install \/usr\/bin\/javac javac \/opt\/jdk-10.0.2\/bin\/javac 2\r\nsudo alternatives --set jar \/opt\/jdk-10.0.2\/bin\/jar\r\nsudo alternatives --set javac \/opt\/jdk-10.0.2\/bin\/javac<\/pre>\n<p>Once done, you can now check what version of Java is currently active on your system:<\/p>\n<pre>sudo java --version<\/pre>\n<p>The output should look similar to this:<\/p>\n<pre>java 10.0.2 2018-07-17\r\nJava(TM) SE Runtime Environment 18.3 (build 10.0.2+13)\r\nJava HotSpot(TM) 64-Bit Server VM 18.3 (build 10.0.2+13, mixed mode)<\/pre>\n<p>When this is completed, you will then need to set your environment variables to correspond with the locations of your Java executables. You will need to create new files using your favorite text editor.<\/p>\n<p>The Bourne Again shell configuration file should be created at the location &#8220;\/etc\/profile.d\/java.sh&#8221;, and should contain these contents:<\/p>\n<pre>if ! echo ${PATH} | grep -q \/opt\/jdk-10.0.2\/bin ; then\r\n   export PATH=\/opt\/jdk-10.0.2\/bin:${PATH}\r\nfi\r\nif ! echo ${PATH} | grep -q \/opt\/jdk-10.0.2\/jre\/bin ; then\r\n   export PATH=\/opt\/jdk-10.0.2\/jre\/bin:${PATH}\r\nfi\r\nexport JAVA_HOME=\/opt\/jdk-10.0.2\r\nexport JRE_HOME=\/opt\/jdk-10.0.2\/jre\r\nexport CLASSPATH=.:\/opt\/jdk-10.0.2\/lib\/tools.jar:\/opt\/jdk-10.0.2\/jre\/lib\/rt.jar<\/pre>\n<p>Once you have entered and saved this in that new file, you can now create a configuration file for the C Shell. This file should be located and named as &#8220;\/etc\/profile.d\/java.csh&#8221;. The file should contain these contents:<\/p>\n<pre>if ( \"${path}\" !~ *\/opt\/jdk-10.0.2\/bin* ) then\r\n   set path = ( \/opt\/jdk-10.0.2\/bin $path )\r\nendif\r\nif ( \"${path}\" !~ *\/opt\/jdk-10.0.2\/jre\/bin* ) then\r\n    set path = ( \/opt\/jdk-10.0.2\/jre\/bin $path )\r\nendif\r\nsetenv JAVA_HOME \/opt\/jdk-10.0.2\r\nsetenv JRE_HOME \/opt\/jdk-10.0.2\/jre\r\nsetenv CLASSPATH .:\/opt\/jdk-10.0.2\/lib\/tools.jar:\/opt\/jdk-10.0.2\/jre\/lib\/rt.jar<\/pre>\n<p>You have now set the environment variables for Java. Make sure to change the file permissions to the correct values:<\/p>\n<pre>sudo chmod 755 \/etc\/profile.d\/java.sh\r\nsudo chmod 755 \/etc\/profile.d\/java.csh<\/pre>\n<p>We can now continue with the installation of WildFly.<\/p>\n<h2><span class=\"ez-toc-section\" id=\"Step-2-Installing-WildFly\"><\/span>Step 2: Installing WildFly<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>The first step is downloading and extracting the WildFly software package from WildFly&#8217;s website &#8211; download the latest version (14.0.1 at the time of writing this tutorial) by using the following command:<\/p>\n<pre>wget\u00a0http:\/\/download.jboss.org\/wildfly\/14.0.1.Final\/wildfly-14.0.1.Final.tar.gz<\/pre>\n<p>Once the download is finished, you can then extract it by using the next command:<\/p>\n<pre>tar -zxvf\u00a0wildfly-14.0.1.Final.tar.gz<\/pre>\n<p>(You can now delete the downloaded tarball)<\/p>\n<p>You will now need to set two variables found in the standalone configuration file, found at the location &#8220;\/opt\/wildfly-14.0.1.Final\/bin\/standalone.conf&#8221;. The two variables set the location of WildFly, and your Java install location. Using your text editor of choice, add these next two lines to that file:<\/p>\n<pre>JBOSS_HOME=\"\/opt\/wildfly-14.0.1.Final\"\r\nJAVA_HOME=\"\/opt\/jdk-10.0.2\"<\/pre>\n<p>Once this is done, we can now edit the XML configuration file. This file is located at the filepath &#8220;\/opt\/wildfly-14.0.1.Final\/standalone\/configuration\/standalone.xml&#8221;. Open it with your favorite text editor, and replace all instances of a localhost IP address (they need to be written as &#8220;127.0.0.1&#8221;) with your server&#8217;s public IP address. This will allow us to access WildFly from an external network. Once done, we can now start the server and create our first user.<\/p>\n<p>Starting WildFly is simple. Just run the executable:<\/p>\n<pre>sudo \/opt\/wildfly-14.0.1.Final\/bin\/standalone.sh<\/pre>\n<p>Now, while this executable will run the server just fine, it will also run inside of your terminal session, meaning that when your session ends, the server will close as well. You can run it in a screen as well by using the &#8220;screen&#8221; package, but you will still need to start it manually every time your server reboots. To get around this, we created a simple file that will allow you to register WildFly as a service. Just follow these next couple of steps, and you will be able to start and stop WildFly as a regular service, as well as have it run on server boot.<\/p>\n<p>Create a new file at the location &#8220;\/lib\/systemd\/system\/&#8221; named &#8216;wildfly.service&#8217;. The full path should be &#8220;\/lib\/systemd\/system\/wildfly.service&#8221;. Enter the following text into it, and save it.<\/p>\n<pre>[Unit]\r\nDescription=WildFly Server\r\nAfter=httpd.service\r\nStartLimitIntervalSec=0\r\n\r\n[Service]\r\nType=simple\r\nRestart=always\r\nRestartSec=1\r\nUser=root\r\nExecStart=\/opt\/wildfly-14.0.1.Final\/bin\/standalone.sh<\/pre>\n<p>Now, all you need to do is reload the service list:<\/p>\n<pre>systemctl daemon-reload<\/pre>\n<p>And you can now start it as a regular service &#8211; just run it like any other service:<\/p>\n<pre>systemctl start wildfly.service<\/pre>\n<p>And if you wish to enable it so that it runs every time your machine or server boots, that can be done as well:<\/p>\n<pre>systemctl enable wildfly.service<\/pre>\n<h2><span class=\"ez-toc-section\" id=\"Step-3-Creating-a-User\"><\/span>Step 3: Creating a User<span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p>In order to use WildFly, you&#8217;ll need to create a user. This can be done by running the &#8216;add-user&#8217; script found in &#8220;\/opt\/wildfly-14.0.1.Final\/bin\/add-user.sh&#8221; like so:<\/p>\n<pre>sudo \/opt\/wildfly-14.0.1.Final\/bin\/add-user.sh<\/pre>\n<p><strong>Note<\/strong>: You will need to make sure that you create a Management user, as well as add this user to the group &#8220;ManagementRealm&#8221; in order for you to be able to log in.<\/p>\n<p>The script will then guide you through creating a new user. Once the new user is created you can then log in and access WildFly through the web interface. <strong>To access your server<\/strong>, simply enter &#8220;your.public.ip.address:8080&#8221; or &#8220;your.public.ip.address:9990&#8221;. Make sure that ports 8080 and 9990 are both open since those ports are the ones that WildFly listens to. If necessary, you can edit your firewall rules using firewall-cmd or iptables to open these ports for use. Congratulations, you can now begin to use WildFly on your CentOS 7 machine.<\/p>\n<p><img decoding=\"async\" class=\"aligncenter size-full wp-image-28304\" src=\"https:\/\/www.rosehosting.com\/blog\/wp-content\/uploads\/2018\/09\/install-wildfly-14-on-centos-7.jpg\" alt=\"install wildfly 14 on centos 7\" width=\"600\" height=\"320\" srcset=\"https:\/\/www.rosehosting.com\/blog\/wp-content\/uploads\/2018\/09\/install-wildfly-14-on-centos-7.jpg 600w, https:\/\/www.rosehosting.com\/blog\/wp-content\/uploads\/2018\/09\/install-wildfly-14-on-centos-7-150x80.jpg 150w, https:\/\/www.rosehosting.com\/blog\/wp-content\/uploads\/2018\/09\/install-wildfly-14-on-centos-7-300x160.jpg 300w\" sizes=\"(max-width: 600px) 100vw, 600px\" \/><\/p>\n<hr \/>\n<p><img decoding=\"async\" class=\"alignleft size-full wp-image-28305\" src=\"https:\/\/www.rosehosting.com\/blog\/wp-content\/uploads\/2018\/09\/installing-wildfly-14-on-centos-7.jpg\" alt=\"installing wildfly 14 on centos 7\" width=\"230\" height=\"138\" srcset=\"https:\/\/www.rosehosting.com\/blog\/wp-content\/uploads\/2018\/09\/installing-wildfly-14-on-centos-7.jpg 230w, https:\/\/www.rosehosting.com\/blog\/wp-content\/uploads\/2018\/09\/installing-wildfly-14-on-centos-7-150x90.jpg 150w\" sizes=\"(max-width: 230px) 100vw, 230px\" \/>Of course, you do not need to install WildFly 14 on your CentOS 7 VPS yourself if you have a <a href=\"https:\/\/www.rosehosting.com\/centos-hosting.html\">CentOS VPS<\/a> hosted with us, in which case you can simply ask our expert admins to install it for you.
