This tutorial helps you to install Java 8 or update Java on your system. Read the instruction carefully before downloading Java from the Linux command line. The Oracle Java 11 is the latest LTS version available to download and install. To install Oracle Java 11 on CentOS and Fedora system follow below tutorial. Step 1 – Download Latest Java Archive The Oracle team provides Java RPM packages as well as compiled source code.
Java SE Development Kit 8 Downloads. Thank you for downloading this release of the Java™ Platform, Standard Edition Development Kit (JDK™). The JDK is a development environment for building applications, applets, and components using the Java programming language.
Many times I have tried Java installation using rpm packages but I faced some issues. So I decided to install Java using the compiled source code. Since then I have installed a large number of times Java on CentOS, Redhat based systems without any issues. To download the latest Java SE Development Kit 8 release from its or use following commands to download from the shell.
Cd /opt/ wget -no-cookies -no-check-certificate -header 'Cookie: gpwe24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie' 'tar xzf jdk-8u201-linux-x64.tar.gz Step 2 – Install Java 8 with Alternatives The alternatives command is used for maintained symbolic links. This command used to creates, removes, maintains and displays information about the symbolic links comprising the alternatives system.
Let’s use the alternatives command to configure Java on your system. The alternatives command is available in chkconfig package. Cd jdk1.8.0201/ alternatives -install /usr/bin/java java /opt/jdk1.8.0201/bin/java 2 alternatives -config java The newly installed Java version listed at number 4, So input 4 and press enter. Select java version There are 3 programs which provide 'java'.
Selection Command - 1 /opt/jdk1.8.045/bin/java. 2 /opt/jdk1.8.0144/bin/java + 3 /opt/jdk-11/bin/java 4 /opt/jdk1.8.0201/bin/java Enter to keep the current selection+, or type selection number: 4 At this point, JAVA 8 has been successfully installed on your system. We also recommend to setup javac and jar commands path using alternatives alternatives -install /usr/bin/jar jar /opt/jdk1.8.0201/bin/jar 2 alternatives -install /usr/bin/javac javac /opt/jdk1.8.0201/bin/javac 2 alternatives -set jar /opt/jdk1.8.0201/bin/jar alternatives -set javac /opt/jdk1.8.0201/bin/javac Step 3 – Check Installed Java Version Java and javac binaries are available under PATH environment variable. You can use them from anywhere in your system. Let’s check the installed version of Java runtime environment (JRE) on your system by executing the following command. Java -version java version ' 1.8.0201' Java(TM) SE Runtime Environment (build 1.8.0201-b09) Java HotSpot(TM) 64-Bit Server VM (build 25.201-b09, mixed mode) Step 4 – Setup Java Environment Variables Most of Java based application’s uses environment variables to work.

Set the Java environment variables using following commands Set the JAVAHOME, JREHOME and PATH environment variables. Export JAVAHOME=/opt/jdk1.8.0201 export JREHOME=/opt/jdk1.8.0201/jre export PATH=$PATH:/opt/jdk1.8.0201/bin:/opt/jdk1.8.0201/jre/bin Also add the above commands to /etc/bashrc or /etc/environment file to auto set environment variables during the system reboot.
Hi Rahul, I am trying to install jenkins on my centos vm instance but unable to do so as its need java 8 and the java version in my system is 1.7. Now, I am trying to update the java version but due to proxy issue I am getting error so I downloaded the java 8 couple of times “jre-8u181-linux-x64.rpm” and whenever I am trying to execute this rpm file, like below, sudo yum install jre-8u181-linux-x64.rpm But I am getting error like below, Trying other mirror. Error: Cannot retrieve repository metadata (repomd.xml) for repository: local. Please verify its path and try again Could you please navigate me to the correct direction. Looking forward for your reply. Regards Sumit Sahay. Hi Jaydeep, Could you please let me know if you could resolve this?
I am stuck at this point and don’t know how to proceed. Hi, this is an amazing post, and I benefited a lot! But I met a problem. After installing, i checked the version and it was successful. However, I wanted to use the java 1.8 on system boot, and as you suggested I put the last three commands in the “/etc/environment” file.
However, after I did that, my machine is not starting (my machine is a CentOS machine created with Cloudera training vm with help of virtualbox), and giving the following error: Starting jexec servicesDevice, “eth0” does not exist Do you know what is wrong? Can you please reply? Install is the easy part, but can anyone note the reason why you can no longer perform a “yum update jdk” with version 1.8. I have noticed that once the package is installed, the package name format is different than in versions 1.7 and 1.6. Where 1.7 was formatted like so: jdk-1.7.080 Version 1.8 is now formatted like this: jdk1.8.060 This does not allow for a yum update in CentOS or Red Hat. Thanks for any leads on this.
It’s a real pain to manually update. Though I see a benefit in that you would not “yank out” the current version out from under your running java applications. It does appear to make the upgrade safer, but manual too. Hi, I had this problem too with Centos 7. The reason is that if you put the entries in /etc/environment it messes up the PATH environment setting which includes removing reference to /bin. To recover do the following: 1. Ctl-Alt-F2 to switch to a command line console 2.
Login with your account details – you’ll get errors as the shell script runs but don’t worry for the moment 3. Enter the command PATH=$PATH:/bin 4. Enter the command startx 5.
Once the desktop appears open a terminal session 6. Enter the command su – 5.
Enter your root password at the prompt 6. Again, enter PATH=$PATH:/bin 7. Enter the command gedit /etc/environment 8. Delete all lines in the file and save 9. Restart Centos Best regardsPaul. Hi everyone I would to know how resolve this: bash: $’ 342 200 234export’: order not found bash: $’ 342 200 234export’: order not found bash: $’ 342 200 234export’: order not found $ This happens from that I “installed java or detroyed with java my pc” I don’t know why: I have done this: echo “export JAVAHOME=/opt/jdk1.8.0101” /etc/profile.d/jre.sh echo “export JREHOME=/opt/jdk1.8.0101/jre” /etc/profile.d/jre.sh echo “export PATH=$PATH:/opt/jdk1.8.0101/bin:/opt/jdk1.8.0101/jre/bin” /etc/profile.d/jre.sh according to Mark Smith user.
All run fine. After Reboot I get that message in my terminal. Because I don’t know if this affects only to java or all my apps in mi machine Centos7. Hello sir, Im trying to install the latest java on my VPS to run a simple.jar file and the 1st step “tar xzf jdk-8u25-linux-x64.tar.gz” returns # tar xzf jdk-8u25-linux-x64.tar.gz tar (child): jdk-8u25-linux-x64.tar.gz: Cannot open: No such file or directory tar (child): Error is not recoverable: exiting now tar: Child returned status 2 tar: Error is not recoverable: exiting now Running “uname -a” returns, which I presume is 64bit, Im using Centos 6.
#1 SMP Mon Aug 11 18:47:39 MSK 2014 x8664 x8664 x8664 GNU/Linux. I tried installing via both SSH and terminal of the VPS itself.
Both returned the same result, what have I done wrong? Any help would be greatly appreciated. Ying, I had the same issue. I followed the steps exactly but when I tried to test that it was working I kept getting “No such file or directory”. I tried another version of java with the same results. Finally I traced it to (I think) to the alternative command. It seems it could not creating the symbolic link correctly between “/etc/alternatives” and “/opt/jdk1.8.045/bin/java”.
I deleted the existing link “”/etc/alternatives/java” and then recreated it: ln -s /opt/jdk1.8.045/bin/java java and now the command “java -version” displays: java version “1.8.045” Java(TM) SE Runtime Environment (build 1.8.045-b14) Java HotSpot(TM) Server VM (build 25.45-b02, mixed mode). Thank you so much. Maybe useful for other readers: – On a vanilla fedora (or at least on my system), ‘alternatives’ doesn’t seem to be in the path, so the full path has to be specified: sudo /usr/sbin/alternatives –install /usr/bin/java java /opt/jdk1.8.005/bin/java 2 sudo /usr/sbin/alternatives –config java – In case folks are not familar, the export commands can go into /.bashprofile, but careful not to overwrite your existing “PATH”, instead append to it. This is an example of my /.bashprofile #.bashprofile # Get the aliases and functions if -f /.bashrc ; then. /.bashrc fi # User specific environment and startup programs PATH=$PATH:$HOME/.local/bin:$HOME/bin:$HOME/Dropbox/Apps/Bashpathlinux/:/opt/jdk1.8.005/bin:/opt/jdk1.8.005/jre/bin export JAVAHOME=/opt/jdk1.8.005 export JREHOME=/opt/jdk1.8.005/jre export PATH Hope it helps.
