Environment Modules简单使用

Environment Modules简介

Typically users initialize their environment when they log in by setting environment information for every application they will reference during the session. The Environment Modules package is a tool that simplify shell initialization and lets users easily modify their environment during the session with modulefiles.

初始化

刚刚安装好的Environment Modules是没有module这条shell命令的

需要进行简单的配置source一下环境

在profile.d下建立软连接，执行下列语句

# root用户

$ cd /etc/profile.d

$ ln -s /usr/local/Modules/init/profile.sh  module-profile.sh

$ ln -s /usr/local/Modules/init/profile.csh module-profile.csh

# 普通用户(bash)

$ source /usr/local/Modules/init/profile.sh

$ echo "source /usr/local/Modules/init/profile.sh" >> ~/.bashrc

$ which module

module is a function

module ()

{

    _module_raw "$@" 2>&1

}

bash下支持自动补全

# 确认已经安装bash-completion

$ cd /etc/bash_completion.d

ln -s /usr/local/Modules/init/bash_completion modules-compliction.bash

管理工具的不同版本

一个简单的例子

$ cd /usr/local/Modules/modulefiles

$ mkdir riscv_toolchain

$ cd riscv_toolchain

$ touch compile-version

$ touch freedomstudio-version

compile-verison

}

module-whatis   "adds  /opt/riscv/toolchain/bin to your PATH environment variable"

简单使用

$ module load riscv_toolchain/compile-version

$ which riscv64-unknown-elf-gcc

riscv64-unknown-elf-gcc is /opt/riscv/toolchain/bin/riscv64-unknown-elf-gcc

$ module load riscv_toolchain/freedomstudio-version

Loading riscv_toolchain/freedomstudio-version

  ERROR: riscv_toolchain/freedomstudio-version cannot be loaded due to a conflict.

    HINT: Might try "module unload riscv_toolchain/compile-version" first.

$ module unload riscv_toolchain/compile-version 

$ module load riscv_toolchain/freedomstudio-version

$ which riscv64-unknown-elf-gcc

riscv64-unknown-elf-gcc is /opt/FreedomStudio/SiFive/riscv64-unknown-elf-gcc-8.3.0-2019.08.0/bin/riscv64-unknown-elf-gcc

个人环境管理

~/privatemodules/ 与/usr/local/Modules/modulefiles一样可以包含local的环境设置

$ cd ~/

$ mkdir privatemodules/

常用命令
