############## [ 安装 python 3.7 ] #######################
在Ubuntu 18.0.4上只需要下面两条即可，不需要pyenv安装。
sudo apt-get install python3.7
sudo apt-get install python3.7-dev

############## [通过pyenv 管理多个python环境， 这里并不需要，可选]###########
1.安装依赖包

sudo apt-get update
sudo apt-get install build-essential python-dev python-setuptools python-pip python-smbus
sudo apt-get install build-essential libncursesw5-dev libgdbm-dev libc6-dev
sudo apt-get install zlib1g-dev libsqlite3-dev tk-dev
sudo apt-get install libssl-dev openssl
sudo apt-get install libffi-dev


2. 安装pyenv (安装python3)

 git clone git://github.com/pyenv/pyenv.git ~/.pyenv
 echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.bashrc
 echo 'export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.bashrc
 echo 'eval "$(pyenv init -)"' >> ~/.bashrc
 exec $SHELL -l
3. 安装 python3.7.0 （3.7.1等版本都可以）

pyenv install 3.7.0 -v
3.1安装完成之后，需要使用如下命令对数据库进行更新：
pyenv rehash
3.2查看已经安装的python版本：
pyenv versions
* system (set by /root/.pyenv/version)
3.7.0
4.设置全局python版本

pyenv global 3.7.0

[==========在sudo 中保持 env 环境变量=======================]
编辑/etc/sudoers  文件
sudo vi /etc/sudoers
将    Defaults    env_reset 改成 Defaults    !env_reset

编辑 .bashrc文件
sudo vi  .bashrc
在文件末尾添加一行代码
alias sudo='sudo env PATH=$PATH'
直接执行

source ~/.bashrc

sudo update-alternatives --install /usr/bin/python python /usr/bin/python3.7     200
sudo update-alternatives --install /usr/bin/python python /home/michael/pyenv/versions/3.7.1     100

sudo update-alternatives --list python

######################[ 开始安装部署 GreenGrass ]##############################
sudo tar -xzvf greengrass-linux-aarch64-1.10.0.tar.gz -C /
sudo tar -xzvf <hash-setup>.tar.gz -C /greengrass

cd /greengrass/certs/
sudo wget -O root.ca.pem https://www.amazontrust.com/repository/AmazonRootCA1.pem
cat root.ca.pem

cd /greengrass/ggc/core/
sudo ./greengrassd start

ps aux | grep PID-number
ps aux | grep -E 'greengrass.*daemon'
#################################################################################
[报错]GreenGrassSession is not authorized to perform: GetGroupVersion
[原因]如果多次部署greengrass，并且设置了全局的role，就会出现上面的错误。
[解决方案]在全局的setting中解除全局的role。 点击 Detach role。 重新部署应用，然后再重新设置全局的role即可。
