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, 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, 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.

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
[root@kolla ~]# cat .cargo/config
[registry]
index = "https://mirrors.ustc.edu.cn/crates.io-index/"
[source.crates-io]
registry = "https://github.com/rust-lang/crates.io-index"
replace-with = 'ustc'
[source.ustc]
registry = "https://mirrors.ustc.edu.cn/crates.io-index/"
[root@kolla ~]#
[root@kolla ~]# source $HOME/.cargo/env
[root@kolla ~]# rustup --version
