For more about the sudo command and running as root you can checkout the man pages or the CentOS Wiki. Respectively a $ dollar sign indicates you are a normal user. Note that when you see a command-line with a # hash sign at the beginning this is a unix standard indicating that you are logged in ‘as the root user.’ However, if you are not logged in as root, all of the commands displaying a hash sign, # will require ‘sudo’ permissions. I’m installing Java to /usr/local but if you want you can substitute for another location such as /opt or /usr/share. In order to install the binaries we’re going to SSH into the server as root and use GNU Wget to download the dependencies. Installing / Updating to the Latest Java 8 Version Furthermore, we’re obviously going to need Java and Tomcat so let’s get started by installing or updating to the latest versions. (Currently Java 8 1.8.0_45, Tomcat v8.0.21). For more info you can get a pretty good bootstrap lesson on each technology from the StackOverflow wikis… respectively, SSH, Linux and Vim. If you’re not comfortable using Vim you might delegate this task to someone more confident with their skills or using another editor such as Nano or Emacs. If not I’ll show the commands as I go along but those skills are beyond the scope of this guide. To get this build working I’m assuming you are at least casually familiar with basic Linux commands, shell access and a understanding of the Vim editor. Personal Tools of ChoiceĪs I favor using GNU tools and I’m running Windows locally, I’m using a Cygwin-derived toolkit based on Arch Linux called MSYS2, and ConEmu – a superb console emulator for Windows. Note, this is simply a how-to… not a best-practices guide so if you require a security hardened solution I recommend checking out TomcatExpert for an authoritative how-to. As this build requirement is not entirely obvious I thought I’d share the experience as a simple how-to guide. I was recently asked by an associate of mine to deploy a Spring application to a CentOS server running cPanel/WHM and Apache.
