How to Install NetBeans on CentOS ?

Before proceeding with this Installation procedure, ensure that you are using a user with sudo access.

To install NetBeans on CentOS, there are following two methods:

• Installation via installer script.
• Installation via snap.

1. NetBeans Installation via Installer Script

Here, we will install NetBeans using the installer script available at Apache NetBeans's official website. Using this installation method, you can have the latest version of NetBeans. For NetBeans, you will also require JDK installed on your CentOS machine. The complete steps for the installation of NetBeans via installer script are as follows.

i. First, you will need to install JDK on your CentOS system. Use the command below to install it:

$ sudo dnf install java-11-openjdk java-11-openjdk-devel

Enter sudo password and hit y when prompted with y/N.

ii. Next, you will need to download Apache NetBeans on your system. Visit Apache NetBeans official website and download the latest available version of the installer script version for Linux. The latest version available at the NetBeans site is 12.4, but here we are going to download the version 12.0.

You can also use the command below in your Linux Terminal to download the NetBeans installer script version 12.0.

$ wget https://downloads.apache.org/netbeans/netbeans/12.0/Apache-NetBeans-12.0-bin-linux-x64.sh

You can find the downloaded script in your current directory. 

iii. Now run the downloaded script. However, before that, we will need to first make it executable. Use the command below to do so:

$ sudo chmod +x Apache-NetBeans-12.0-bin-linux-x64.sh

Note: Make sure in the above command you mention the correct version of the script you have downloaded. You can also type initial letters like Apache-NetBeans and use the tab to auto complete the name.

iv. After making the script executable, we can run it as follows:

$ sudo ./Apache-NetBeans-12.0-bin-linux-x64.sh

After running the script, the installer wizard will appear on your screen. Click Next to start the installation process.

Then accept the Terms and conditions by checking the box and click Next.

Then choose the installation directory or leave the default directory selected and click Next.

In the next window, check the box named Check for Updates and then hit Install button.

Next, the installation of Apache NetBeans will be started.
