Create Root CA (Done once)

Create Root Key

Attention: this is the key used to sign the certificate requests, anyone holding this can sign certificates on your behalf. So keep it in a safe place!

为Mac 设置Python多版本开发环境

##参考链接

##问题 - 可能会遇到多个版本同时部署的情况

  • 系统自带的Python是2.x,自己需要Python 3.x,测试尝鲜;
  • 系统是2.6.x,开发环境是2.7.x
  • 由于Mac机器系统保护的原因,默认的Python中无法对PIP一些包升级,需要组建新的Python环境
  • 此时需要在系统中安装多个Python,但又不能影响系统自带的Python,即需要实现Python的多版本共存。pyenv就是这样一个Python版本管理器

##解决方法 - pyenv
