Today, you will learn how To Install Java and Java SE Development Kit on AlmaLinux 9
Install Java on AlmaLinux:
Follow the steps below to get started with Java:
- Update your AlmaLinux system packages with running the below command:
sudo dnf clean all && sudo dnf update
sudo dnf groupinstall "Development Tools"- Java package is not available on AlmaLinux base repository. So You can run the following command to download OpenJDK installer to your AlmaLinux system as follows:
wget https://download.java.net/java/GA/jdk18.0.2/f6ad4b4450fd4d298113270ec84f30ee/9/GPL/openjdk-18.0.2_linux-x64_bin.tar.gz
- Extract the downloaded file then move the extracted files to /mnt directory.
tar xvf openjdk-18.0.2_linux-x64_bin.tar.gz sudo mv jdk-18.0.2 /mnt/
- After that, configure the Java environment by editing the file below :
sudo vim /etc/profile.d/jdk18.sh
Then add the following:
export JAVA_HOME=/opt/jdk-18
export PATH=$PATH:$JAVA_HOME/bin
- Check the java command:
source /etc/profile.d/jdk18.sh
- Also try to verify the OpenJDK installation by running the command below:
echo $JAVA_HOME
Install Java SE Development Kit on AlmaLinux:
- Java SE Dev Kit package is not available on RHEL base repository. So You can download it with the following command:
wget https://download.oracle.com/java/19/latest/jdk-19_linux-aarch64_bin.rpm
- Then install the Java SE Dev Kit as shown below:
sudo rpm -Uvh jdk-19_linux-aarch64_bin.rpm
- Verify the installation:
java -version
After that, configure the Java environment by editing the file below :
sudo vim /etc/profile.d/jdk18.sh
Then add the following:
export JAVA_HOME=/usr/java/default
export PATH=$PATH:$JAVA_HOME/bin
Check the java command:
source /etc/profile.d/jdk18.sh
NOTE:
If you have multiple versions of Java, you can use the command below to manage the version you want:
sudo alternatives --config java
