• What do Etcd, Consul, and Zookeeper do?
  • Service Registration:
    • Host, port number, and sometimes authentication credentials, protocols, versions numbers, and/or environment details.
  • Service Discovery:
    • Ability for client application to query the central registry to learn of service location.
  • Consistent and durable general-purpose K/V store across distributed system.
    • Some solutions support this better than others.
    • Based on Paxos or some derivative (i.e. Raft) algorithm to quickly converge to a consistent state.
• Centralized locking can be based on this K/V store.

##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
