Step 3: Install Rust Programming Language in Linux

After successfully updating your System, it is now time to install Rust Programming Language using below curl command. Below curl command will install Rust Programming Language in Linux using rustup tool. It will download and install the Rust Programming Language Compiler known as Cargo. Once you run the below command it will ask you to select the option to proceed with the Installation.

You need to Select Option 1 to proceed with the steps to install Rust Programming Language in Linux. It will download all the required Rust Programming Language Components as shown below.

[root@localhost ~]# curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
info: downloading installer

Welcome to Rust!

This will download and install the official compiler for the Rust
programming language, and its package manager, Cargo.

It will add the cargo, rustc, install rustup and other commands to
Cargo's bin directory, located at:

/root/.cargo/bin

This can be modified with the CARGO_HOME environment variable.

Rustup metadata and toolchains will be installed into the Rustup
home directory to install Rust, located at:

/root/.rustup

This can be modified with the RUSTUP_HOME environment variable.

This path will then be added to your PATH environment variable by
modifying the profile files located at:

/root/.profile
/root/.bash_profile

You can uninstall at any time with rustup self uninstall and
these changes will be reverted.

Current installation options:

default host triple: x86_64-unknown-linux-gnu
default toolchain: stable
profile: default
modify PATH variable: yes

1) Proceed with installation (default)
2) Customize installation
3) Cancel installation

info: profile set to 'default'
info: default host triple is x86_64-unknown-linux-gnu
info: syncing channel updates for 'stable-x86_64-unknown-linux-gnu'

stable installed - rustc 1.44.1 (c7087fe00 2020-06-17)

Rust is installed now. Great!

To get started you need Cargo's bin directory ($HOME/.cargo/bin) in your PATH
environment variable. Next time you log in this will be done
automatically.

To configure your current shell run source $HOME/.cargo/env

Step 4: Configure Rust Programming Language in Linux

After successful installation of Rust Programming Language Components, you can configure your current shell by running source $HOME/.cargo/env command. It will configure the current logged in User shell to run the Rust programs.

If you open ~/.profile and ~/.cargo/env file you will see bin path added in global environment variable $PATH. If it is not added you need to add it manually to make rust programming tool work.

[root@localhost ~]# source $HOME/.cargo/env
[root@localhost ~]# cat ~/.profile
export PATH="$HOME/.cargo/bin:$PATH"
[root@localhost ~]# cat ~/.cargo/env
export PATH="$HOME/.cargo/bin:$PATH"

Step 5: Check Rust version

After adding rust bin tools in $PATH you can check the rust tool version using rustc --version command as shown below. As you can see from below output, currently installed rustc version is 1.44.1.

[root@localhost ~]# rustc --version
rustc 1.44.1 (c7087fe00 2020-06-17)

Step 6: Test Rust Programming Language in Linux

It is now time to test the Rust Programming Language by writing a simple program as shown below. Let's create a directory example first and then go to that directory and create a file known as hello.rs. You can notice here that the Rust Program should be saved with .rs extension. Here we will write a simple print program to display "This is hello from CyberITHub" in the Standard Output.

[root@localhost ~]# mkdir example
[root@localhost ~]# cd example
[root@localhost example]# vi hello.rs
fn main()
{
println!("This is hello from CyberITHub");
}

After saving above program you need to compile it using rustc hello.rs command as shown below. If compilation is successful then you will see an executable file hello generated in the current directory. This executable needs to be run using ./hello command. Upon successful execution, it will display the output "This is hello from CyberITHub" as specified below.

[root@localhost example]# rustc hello.rs
[root@localhost example]# ls -lrt
total 2848
-rw-r--r-- 1 root root 58 Jun 28 14:02 hello.rs
-rwxr-xr-x 1 root root 2912208 Jun 28 14:02 hello
[root@localhost example]# ./hello
This is hello from CyberITHub
