Installing JDK

To ensure that Edge Flow Management functions correctly, you need to install JDK on each machine where the EFM server will be installed.

Download the JDK package from the appropriate website.
Run the following installation command.
For RHEL/CentOS:
```
yum install java-17-openjdk
```

After installing the JDK, ensure that you have the required database installed and properly configured for Edge Flow Management.
