Install Rust Toolchain (Linux Cloud VPS)

Unlike popular languages like C and Python, which have GCC and CPython bundled in most Linux releases, Rust does not (yet) have native support on Linux and must be installed separately.

This guide will help if you want to install the Rust development toolchain. You'll need a Linux host with shell access to get started.

#1 - Update Rust root dir

# export RUSTUP_HOME='~/.rustup' 

#2 - Install rustup

# curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh 

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

To proceed with the default Rust installation, type 1 when prompted, and press Enter. If you want to modify PATH variables, change the toolchain stream, or add a profile, you can select 2 and provide custom values for each.

#3 - Apply installation PATH changes

# source ~/.bash_profile 

#4 - Set Profile

Rust comes with separate profiles that control which Rust tools are installed in the current environment. The default profile is selected during the installation. You can change profiles at any time

• minimal - rustc, rust-std, cargo
• default - rustc, rust-std, cargo, rust-docs, rustfmt, clippy

# rustup set profile minimal 

#5 - Verify Rust toolchain installation

# which rustc /root/.cargo/bin/rustc 

#6 - Install 'build-essential' package

rustc utilizes the GCC linker for the linking stage of compilation. Your host may or may not have cc available. You can install build-essential the following way:

Distro

Command

RHEL / CentOS / Amazon Linux

sudo yum install gcc gcc-c++ make

Ubuntu / Debian

sudo apt-get install build-essential

Fedora

sudo yum install make gcc gcc-c++ kernel-devel

At this point, the Rust toolchain has been installed and is ready to use. You can test the Rust toolchain by compiling and executing a test Rust program:

#7 - Create a 'Hello World' Rust Program

# echo -e 'fn main() {\n\tprintln!("Hello from Hostwinds!");\n}' >> hellorust.rs

# cat hellorust.rs
fn main() {
println!("Hello from Hostwinds!");
} 

#8 - Compile with the rustc compiler

# rustc hellorust.rs 

The compiler should output a single file named 'hellorust' which is a compiled binary of the hellorust.rs program:

# file hellorust
hellorust: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked, interpreter /lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, BuildID[sha1]=b7a1b1e072fb63c7be826f7964636d6a3b628485, with debug_info, not stripped, too many notes (256)

You can now execute your compiled rust program:

# ./hellorust

Hello from Hostwinds!
