How to Install JAVA 7 (JDK 7u79) on CentOS/RHEL 7/6/5 and Fedora

Last updated October 16, 2017 by
JAVA, Linux Tutorials , , , , ,
Warning – Java 7 is officially deprecated by Oracle team. It is no more available for download on the public network. The Oracle team recommends upgrading to Java 8 or Java 9. You can follow below tutorials to install accordingly.

During installation of Java using rpm files, I faced issues many times. After that, I found a better way to install java from Sun site. Using below steps I have installed java successfully many times without facing any issues. We can also install multiple version of java easily if required. Oracle has also released Java 8. To install it read article

Use following step by step instructions to install or update Java. I recommend reading carefully instruction for downloading Java from Linux command line.

Downloading Latest Java Archive

Java latest archive is available on its official site. We recommend to download latest version of Java from Oracle official website. After completing download also extract archive with given commands.

For 64 Bit:-

# cd /opt/
# 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/7u79-b15/jdk-7u79-linux-x64.tar.gz"

# tar xzf jdk-7u79-linux-x64.tar.gz

For 32 Bit:-

# cd /opt/
# 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/7u79-b15/jdk-7u79-linux-i586.tar.gz"

# tar xzf jdk-7u79-linux-i586.tar.gz

Note: If Above wget command doesn’t not work for you watch this example video to download java source archive using terminal.

Use archive file as per your system configuration. For this example we are using CentOS 7.0 (64 bit) system.

Install Java with Alternatives

After extracting Java archive file, we just need to set up to use newer version of Java using alternatives. Use the following commands to do it.

# cd /opt/jdk1.7.0_79/
# alternatives --install /usr/bin/java java /opt/jdk1.7.0_79/bin/java 2
# alternatives --config java

There are 3 programs which provide 'java'.

  Selection    Command
-----------------------------------------------
*  1           /opt/jdk1.7.0_60/bin/java
 + 2           /opt/jdk1.7.0_72/bin/java
   3           /opt/jdk1.7.0_79/bin/java

Enter to keep the current selection[+], or type selection number: 3 [Press Enter]

Now you may also required to set up javac and jar commands path using alternatives command.

# alternatives --install /usr/bin/jar jar /opt/jdk1.7.0_79/bin/jar 2
# alternatives --install /usr/bin/javac javac /opt/jdk1.7.0_79/bin/javac 2
# alternatives --set jar /opt/jdk1.7.0_79/bin/jar
# alternatives --set javac /opt/jdk1.7.0_79/bin/javac
Check Installed Java Version

Use following command to check which version of Java is currently being used by system.

# java -version

java version "1.7.0_79"
Java(TM) SE Runtime Environment (build 1.7.0_79-b15)
Java HotSpot(TM) 64-Bit Server VM (build 24.79-b02, mixed mode)
Configuring Environment Variables

Most of Java based application’s uses environment variables to work. Use following commands to set up these variable properly. It’s also good to add following commands to any start-up script like ~/.bashrc or ~/.bash_profile.

  • Setup JAVA_HOME Variable
    • # export JAVA_HOME=/opt/jdk1.7.0_79
  • Setup JRE_HOME Variable
    • # export JRE_HOME=/opt/jdk1.7.0_79/jre
  • Setup PATH Variable
    • # export PATH=$PATH:/opt/jdk1.7.0_79/bin:/opt/jdk1.7.0_79/jre/bin

I hope above steps will help you for installing Java on your Linux system. You can follow above steps to install multiple version of Java as same time but you can use only one version at a time.

    I had old java6 installed:

    # java -version
    java version “1.6.0_41”
    Java(TM) SE Runtime Environment (build 1.6.0_41-b02)
    Java HotSpot(TM) 64-Bit Server VM (build 20.14-b01, mixed mode)

    so I’ve installed java7 as mentioned above, and:
    [[email protected] ~]# alternatives –config java

    There are 2 programs which provide ‘java’.

    Selection Command
    ———————————————–
    * 1 /usr/java/default/java
    + 2 /opt/jdk1.7.0_75/bin/java

    Enter to keep the current selection[+], or type selection number:

    however java -version still claims (even after reboot):
    # java -version
    java version “1.6.0_41”
    Java(TM) SE Runtime Environment (build 1.6.0_41-b02)
    Java HotSpot(TM) 64-Bit Server VM (build 20.14-b01, mixed mode)

    what is wrong?

    I installed all the steps, however, I am facing issue setting-up JAVA_HOME and JRE_HOME. Once I export both the home and exit, the path resets to its original states.. JAVA_HOME turns to null when I echo $JAVA_HOME or echo $JRE_HOME

    I am using su to set them up.

    Otherwise the installation instructions are superb. The only issue I found in the step is that the directory structure you mentioned is hadoop/hadoop whereas (if I am not wrong) it should have been hadoop/hadoop-1.2.1 Please let me know if I am wrong so I can rectify it.

    Thanks in advance.

    January 16, 2014 at 5:03 pm

    Nice article thanks for posting it.

    It should be noted that there are other commands from the JDK/JRE referenced in the alternatives directory that may cause problems if not all of the alternatives are updated. If you look at /etc/alternatives and look for all of the associated applications that are provided with java (maybe something like ls -l /etc/alternatives |grep ‘jvm|java|jre|jdk’ ) you will notice much more than just the java command.

    For example, if you followed steps 1-2 and then ran javac, javaws, javadoc, jar, keytool, appletviewer, javah, etc… you will not get those installed from the jdk tarball in /opt but rather those installed via package (if something like the java-1.6.0-openjdk-devel package is installed) .

    After step 4 you will get it but not because of the alternatives system but because of the change in the PATH variable in step 4 which is user specific unless set in /etc/profile, /etc/profile.d/, or other system wide environment. So if you have a system process that uses javac, javadoc or a command other than java I believe you will not get the version in /opt. I believe that debian based systems (mint, ubuntu, etc.) have an update-java-alternatives command used for this purpose (to update all java related commands) but I don’t know at the moment if it is available for RHEL and derivatives like CentOS.

    Just thought I would share this in case other ran into issues.

      I run into this because I typed java after I finished these commands:

      # alternatives –install /usr/bin/java java /opt/jdk1.7.0_67/bin/java 2
      # alternatives –config java
      and it works.
      but I can’t make it work after I finish these command:
      # alternatives –install /usr/bin/jar jar /opt/jdk1.7.0_67/bin/jar 2
      # alternatives –install /usr/bin/javac javac /opt/jdk1.7.0_67/bin/javac 2
      # alternatives –set jar /opt/jdk1.7.0_67/bin/jar
      # alternatives –set javac /opt/jdk1.7.0_67/bin/javac
      System told me “-bash: javac: command not found”.

    Tried to do this but at Step 1, after copy/pasting the wget command, I get:
