-# YOHO Center Switch
-
-
-## 准备`ansible`的环境
-
-
->1.创建用户： `useradd ansible -g root -d /home/ansible`.
->  
->2.安装`ansible`
->
->3.将被管理的服务器的`private key` copy 到 `~/.ssh/`
->
->4.`git clone` 本项目即可
-
-
-## 依赖:
-
-
->仅支持大于等于2.7.3并小于3.0的python版本
->
->python模块: qcloud、ansible
->
->安装python模块: pip install qcloud ansible
->
->依赖脚本: switch_lb.py (http://git.yoho.cn/ops/yoho-ansible-roles/blob/master/scripts/switch_lb.py) clone本项目即可无需单独下载
-
-
-### `switch.ini`: `switch.ini`的配置
-
->参考scripts/switch/switch.ini
-  
-
- 
-
-
-  
-
-## How to Run
-
-
->根据需要修改本地配置文件switch.ini(http://git.yoho.cn/ops/yoho-ansible-roles/blob/master/scripts/switch/switch.ini)
->
->需在配置文件中准确填写相关的密钥、密码、负载均衡等信息
->
->需进入脚本所在目录下执行脚本(/home/ansible/yoho-ansible-roles/scripts/switch)
-
-```
-
-cd /home/ansible/yoho-ansible-roles/scripts/switch
-python center_switch.py --config=switch.ini
-```
