 6 info: downloading installer
 7 
 8 Welcome to Rust!
 9 
10 This will download and install the official compiler for the Rust
11 programming language, and its package manager, Cargo.
12 
13 Rustup metadata and toolchains will be installed into the Rustup
14 home directory, located at:
15 
16   /root/.rustup
17 
18 This can be modified with the RUSTUP_HOME environment variable.
19 
20 The Cargo home directory is located at:
21 
22   /root/.cargo
23 
24 This can be modified with the CARGO_HOME environment variable.
25 
26 The cargo, rustc, rustup and other commands will be added to
27 Cargo's bin directory, located at:
28 
29   /root/.cargo/bin
30 
31 This path will then be added to your PATH environment variable by
32 modifying the profile files located at:
33 
34   /root/.profile
35   /root/.bash_profile
36   /root/.bashrc
37 
38 You can uninstall at any time with rustup self uninstall and
39 these changes will be reverted.
40 
41 Current installation options:
42 
43 
44    default host triple: x86_64-unknown-linux-gnu
45      default toolchain: stable (default)
46                profile: default
47   modify PATH variable: yes
48 
49 1) Proceed with installation (default)
50 2) Customize installation
51 3) Cancel installation
52 >1 (按键'enter'，保持默认)
53 
54 info: profile set to 'default'
55 info: default host triple is x86_64-unknown-linux-gnu
56 warning: Updating existing toolchain, profile choice will be ignored
57 info: syncing channel updates for 'stable-x86_64-unknown-linux-gnu'
58 info: default toolchain set to 'stable-x86_64-unknown-linux-gnu'
59 
60   stable-x86_64-unknown-linux-gnu unchanged - rustc 1.65.0 (897e37553 2022-11-02)
61 
62 
63 Rust is installed now. Great!
64 
65 To get started you may need to restart your current shell.
66 This would reload your PATH environment variable to include
67 Cargo's bin directory ($HOME/.cargo/bin).
68 
69 To configure your current shell, run:
70 source "$HOME/.cargo/env"
71 [root@rocky temp]#

　　1.2　　configure environment of rust and cargo ( /etc/profile ) ( ref:　　https://www.rust-lang.org/tools/install )

　　　　1.2.1　　show images

　　　　1.2.2　　vim /etc/profile

　　　　1.2.3　　RUST_INSTALL=/root/.cargo/bin　　　　PATH=$PATH:${RUST_INSTALL}　　( /etc/profile )

 1 [root@rocky temp]# cat  /etc/profile
 2 # /etc/profile
 3 
 4 # System wide environment and startup programs, for login setup
 5 # Functions and aliases go in /etc/bashrc
 6 
 7 # It's NOT a good idea to change this file unless you know what you
 8 # are doing. It's much better to create a custom.sh shell script in
 9 # /etc/profile.d/ to make custom changes to your environment, as this
10 # will prevent the need for merging in future updates.
