# Amazon Corretto 8 Installation Instructions for Amazon Linux 2 and Amazon Linux 2023
Installing on Amazon Linux

 This topic describes how to install and uninstall Amazon Corretto 8 on a host or container running the Amazon Linux 2 or Amazon Linux 2023 operating systems. 

## Option 1: Install using the yum Package Manager on Amazon Linux


1.  Enable the yum repository in Amazon Linux 2. This is not required on Amazon Linux 2022 and later.   
**Example**  

   ```
   sudo amazon-linux-extras enable corretto8
   ```

1.  You can install Amazon Corretto 8 as either the runtime environment (JRE) or the full development environment (JDK). The development environment includes the runtime environment. 

   Install Amazon Corretto 8 as JRE.  
**Example**  

   ```
   sudo yum install java-1.8.0-amazon-corretto
   ```

   Install Amazon Corretto 8 as JDK.  
**Example**  

   ```
   sudo yum install java-1.8.0-amazon-corretto-devel
   ```

 The installation location is `/usr/lib/jvm/java-1.8.0-amazon-corretto.<cpu_arch>`. 

 While it is recommended to use `/usr/lib/jvm/java-1.8.0-amazon-corretto.<cpu_arch>` location, installation may also add alternative links making installation location accessible via `/etc/alternatives/jre`, `/etc/alternatives/jre_1.8.0` and `/etc/alternatives/jre_1.8.0_openjdk` for JRE and `/etc/alternatives/java_sdk`, `/etc/alternatives/java_sdk_1.8.0` and `/etc/alternatives/java_sdk_1.8.0_openjdk` for JDK. The paths under `/etc/alternatives/` may point to another JDK depending on the packages installed and system configuration. 

## Option 2: Download and Install RPMs Manually


1.  Download RPMs from the [Downloads](downloads-list.md) page for your CPU architecture. To install the JDK, you will need to download the RPMs for both the JDK and the JRE. 

1.  Install using `yum localinstall`.   
**Example**  

   ```
   sudo yum localinstall java-1.8.0-amazon-corretto*.rpm
   ```

## Verify Your Installation


 In the terminal, run the following command to verify the installation. 

**Example**  

```
java -version
```
Expected output for 8u482:   

```
openjdk version "1.8.0_482"
OpenJDK Runtime Environment Corretto-8.482.08.1 (build 1.8.0_482-b08)
OpenJDK 64-Bit Server VM Corretto-8.482.08.1 (build 25.482-b08, mixed mode)
```

 If you see a version string that doesn't mention `Corretto`, run the following command to change the default `java` or `javac` providers. 

**Example**  

```
sudo alternatives --config java
```
If using the JDK you should also run:  

```
sudo alternatives --config javac
```
