1、下载安装包

https://docs.conda.io/en/latest/miniconda.html

  sudo wget https://repo.anaconda.com/miniconda/Miniconda3-py37_4.10.3-Linux-x86_64.sh

2、执行安装

bash Miniconda3-latest-Linux-x86_64.sh

一直"enter，然后按照指引操作"

3、执行初始化

3.1、自动执行初始化选择yes

3.2、手动初始化

#进入安装目录
cd $install/miniconda3/
condabin/conda init
source ~/.bashrc

4、检验

 conda activate  ###激活虚拟python3环境
 python  --version
 conda deactivate ###退出虚拟python3环境

5、troubleshooting

5.1、 针对调度进程使用python3环境，需先手动启用python环境需要加执行命令

  source /root/.bashrc  #这种要授权

如无法授权可以在脚本前手动执行激活python3环境

__conda_setup="$('/root/miniconda3/bin/conda' 'shell.bash' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
    eval "$__conda_setup"
else
    if [ -f "/root/miniconda3/etc/profile.d/conda.sh" ]; then
        . "/root/miniconda3/etc/profile.d/conda.sh"
    else
        export PATH="/root/miniconda3/bin:$PATH"
    fi
fi
unset __conda_setup

conda放到SDCARD上的配置：

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/SDCARD/miniconda3/bin/conda' 'shell.bash' 'hook' 2> /
dev/null)"
if [ $? -eq 0 ]; then
    eval "$__conda_setup"
else
    if [ -f "/SDCARD/miniconda3/etc/profile.d/conda.sh" ]; then
        . "/SDCARD/miniconda3/etc/profile.d/conda.sh"
    else
        export PATH="/SDCARD/miniconda3/bin:$PATH"
    fi
fi
unset __conda_setup
# <<< conda initialize <<<

也可以通过直接创建软连

 ln -s /data1/miniconda3/bin/python /usr/bin/python3

5.2、conda创建指定版本Python环境

• 服务连上互联网

• conda

  conda create -n your_env_name python=x.x
  #demo，会自动联网下载包放到$conda/env
  

  conda create -n mypython python=2.7.5

创建环境变量

ln -s  /root/miniconda3/envs/test_py2/bin/python   /usr/bin/python2  

5.3、conda环境复制

 scp  $install_home/miniconda3  hosts:/$install_home
 ssh hosts
 $install_home:/condbin/conda init
 source ~/.bashrc
