linux 安装 rust-lang
自动安装
apt install rust
这个是不带cargo/rustup那些的
手动安装
- 安装rustup
wget https://github.com/rust-lang-nursery/rustup.rs/archive/1.14.0.tar.gz
tar xzvf 1.14.0.tar.gz
cd rustup.rs-1.14.0
./rustup-init.sh
需。。如果半天不动，手动去下载如下安装文件。。
wget https://static.rust-lang.org/rustup/dist/x86_64-unknown-linux-gnu/rustup-init
vim rustup-init.sh
注释掉103行的下载步骤。手动指定刚刚下载的安装文件rustup-init
# ensure downloader "$_url" "$_file"
_file="/root/download/rustup.rs-1.14.0/rustup-init"
注释掉132行左右的rm，免得被误删。。
#ignore rm "$_file"
#ignore rmdir "$_dir"
保存退出
//加上中科大镜像
vim /etc/profile
export RUSTUP_DIST_SERVER=https://mirrors.ustc.edu.cn/rust-static
export RUSTUP_UPDATE_ROOT=https://mirrors.ustc.edu.cn/rust-static/rustup
md ~/.cargo && vim ~/.cargo/config
[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'
./rustup-init.sh -y
这时候无需就会自动安装了。
$ ./rustup-init.sh -y
