一条命令完成全部安装

echo "中途需要按回车键确认安装"; yum install -y gcc ;echo "export RUSTUP_DIST_SERVER=https://mirrors.ustc.edu.cn/rust-static";echo "export RUSTUP_UPDATE_ROOT=https://mirrors.ustc.edu.cn/rust-static/rustup";echo "export RUSTUP_DIST_SERVER=https://mirrors.ustc.edu.cn/rust-static" >> /etc/profile;echo "export RUSTUP_UPDATE_ROOT=https://mirrors.ustc.edu.cn/rust-static/rustup" >> /etc/profile;source  /etc/profile;curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh &&source $HOME/.cargo/env &&rustc -V &&echo "${HOME}/.cargo/config";echo "[source.crates-io]" ;echo 'registry = "https://github.com/rust-lang/crates.io-index"' ;echo "replace-with = 'ustc'";echo "[source.ustc]" ;echo 'registry = "git://mirrors.ustc.edu.cn/crates.io-index"' ;echo "[source.crates-io]" >>  ${HOME}/.cargo/config &&echo 'registry = "https://github.com/rust-lang/crates.io-index"' >>  ${HOME}/.cargo/config &&echo "replace-with = 'ustc'" >>  ${HOME}/.cargo/config &&echo "[source.ustc]" >>  ${HOME}/.cargo/config &&echo 'registry = "git://mirrors.ustc.edu.cn/crates.io-index"' >>  ${HOME}/.cargo/config

安装完成后，需要验证是否可用，请跳转到后边的：使用Rust ，以验证

安装Rust

依赖准备

安装gcc

yum install -y gcc

换国内源下载

两条命令进行国内下载安装文件地址配置

vim /etc/profile

在最后填写如下内容

export RUSTUP_DIST_SERVER=https://mirrors.ustc.edu.cn/rust-static
export RUSTUP_UPDATE_ROOT=https://mirrors.ustc.edu.cn/rust-static/rustup

使得环境变量生效

source  /etc/profile

安装

使用命令安装，中间会有阻塞等待输入，直接按回车就是默认安装

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

配置环境变量

安装完成后，需要添加环境变量，才能生效

source $HOME/.cargo/env

安装完成检查

查看版本

rustc -V
# 输出 > rustc 1.77.1 (7cf61ebde 2024-03-27)

依赖包换源

vim ${HOME}/.cargo/config

然后输入下边的内容来设置国内依赖包下载地址

[source.crates-io]
registry = "https://github.com/rust-lang/crates.io-index"
replace-with = 'ustc'
[source.ustc]
registry = "git://mirrors.ustc.edu.cn/crates.io-index"

使用Rust

Hello world

vim helloworld.rs

输入内容：

fn main(){
        let test = "Hello, I love the world!";
        println!("{}",test);
}

编译运行

rustc helloworld.rs  # 编译
./helloworld # 运行编译后生成的文件

使用依赖包

创建程序

例如使用 random 的包；这需要创建一个二进制程序：

cargo new rustrandom
cd rustrandom

创建的 rustrandom 的目录结构是

.
├── Cargo.toml
└── src
    └── main.rs

添加包

vim Cargo.toml
在内容的最后添加：

rand = "0.6.5"

Cargo.toml

[package]
name = "rustrandom"
version = "0.1.0"
edition = "2021"

# See more keys and their definitions at https://doc.rust-lang.org/cargo/reference/manifest.html

[dependencies]
rand = "0.6.5"

使用包

编辑 rustrandom 目录下的 src/main.rs 文件
vim src/main.rs

extern crate rand;
use rand::Rng;
fn main() {
   let num = rand::thread_rng().gen_range(0, 100);
    println!("生成在0（包括）到100（包括）之间的数：{}", num);
}

运行

cargo run
首次运行会下载安装依赖包

再次运行就不会下载了。
