Ubuntu Install Zulu Java
I am trying to install an application called OpenHAB, which recommends using ZULU. When I attempt to do this I receive the following error, I am not very savvy with UNIX?CLI so any information on what needs to be changed would help. I also noted when checking the version command that this current MacOSX (9.0.4)version does not report (build 1.X.X) as indicated in the install guide.Last login: Wed Feb 7 10:47:33 on ttys000ulwil-454-bs: administrator$ /Users/administrator/Downloads/openhab-2/start.shLaunching the openHAB runtimeUnable to find any JVMs matching version “1.8”.Java 1.8 or higher is required.

Recently I moved my server to Ubuntu from windows. I went with Ubuntu 16.04 server edition as it is lightweight as compared to desktop edition and comes preloaded with some server tools. As I am running OpenHAB for my home automation system I wanted to install it on the server but the server edition doesn’t come with JAVA/JDK pre-installed. As per OpenHAB, Zulu JDK is the recommended JAVA platform and performs better as compared to OpenJDK. Though Oracle JDK can be installed, I thought of trying ZULU. So let’s see how to install it.Zulu comes with JDK for almost all OS and both in 32/64 bit edition. The installation method included using the repository or downloading the zip file.
How To Install Zulu Java On Raspberry Pi
First I tried with apt-get (For Ubuntu) method by adding the repositories as provided on their site, but unfortunately, that didn’t work for me. So I moved ahead by downloading the zip file. STEP 2 (Extract and Copy)After download complete, copy the downloaded file to the server by using any method like drive or SCP or anything else. Create a folder jvminside / usr /lib folder. You can use any location that you are interested in.
Mkdir /usr/lib/jvmCopy the zip file to the newly created directory and extract it. Cp zulu8.30.0.1-jdk8.0.172-linuxi686.tar.gz /usr/lib/jvm/cd /usr/lib/jvm/sudo tar -xzvf zulu8.30.0.1-jdk8.0.172-linuxi686.tar.gzThe extracted files will be in a new folder and the will have a long name, so for convenience rename it to something shorter, sudo mv zulu8.30.0.1-jdk8.0.172-linuxi686 zulu-8That’s it, we don’t need any script to run for installation or build. Simply extraction organizes the files into respective folders and all are precompiled binaries.
Now you can use JAVA by navigating to the folder /bin inside the installation directory. STEP 3 (Setting up Environment Variables):Though JAVA can be used by navigating to the installation folder, it’s not convenient any tools we will be installing, we will have to provide the path to the JSK folder manually. So to avoid that we need to setup couples of Environmental Variables like JAVAHOMEand PATH. While JAVAHOMEis used by tools installed on the system like IDE and all to find out the installed JAVA folder, PATHis used by the system to find the same. To set it up, use the following commands, sudo nano /etc/environmentAt the end of the PATHline add:/usr/lib/jvm/zulu-8/bin.

Again don’t forget to change the path, if you have installed the JDK into some other directory and same foes with the JAVAHOMEvariable.Add the following line to the file and save it.JAVAHOME=”/usr/lib/jvm/zulu-8″Now use source /etc/environmentIt loads the system variables. By typing in java -version into the terminal, you can check if everything went right. If you have multiple installations of JDK, you can change the default JDK to use, by using the command, sudo update-alternatives -config java.
