+# ServerStatus中文版：
+
+* ServerStatus中文版是一个酷炫高逼格的云探针、云监控、服务器云监控、多服务器探针~。
+* 在线演示：https://tz.cloudcpp.com
+
+# 目录介绍：
+
+* clients 客户端文件
+* server 服务端文件
+* web 网站文件
+
+# 更新说明：
+
+* 20180314, 调整前端，置默认密码为，设置ip和user即可上线
+* 20180312, 加入失联(被照顾)检测【正常：MH361, 屏蔽：MH370】，校准虚拟化(container)流量统计异常
+* 20170807, 更新平均1，5，15负载
+* 20170607, 去掉无用的IPV6信息，增加服务器总流量监控
+
+# 安装教程：
+
+【克隆代码】:
+```
+git clone https://github.com/cppla/ServerStatus.git
+```
+
+【服务端配置】（服务端程序在ServerStatus/web下）:
+
+一、生成服务端程序
+```
+cd ServerStatus/server
+make
+./sergate
+```
+如果没错误提示，OK，ctrl+c关闭；如果有错误提示，检查35601端口是否被占用
+
+二、修改配置文件
+修改config.json文件，注意username, password的值需要和客户端对应一致
+```
+{"servers":
+ [
+ {
+ "username": "s01",
+ "name": "Mainserver 1",
+ "type": "Dedicated Server",
+ "host": "GenericServerHost123",
+ "location": "Austria",
+ "password": "some-hard-to-guess-copy-paste-password"
+ },
+ ]
+}
+```
+
+三、拷贝ServerStatus/status到你的网站目录
+例如：
+```
+sudo cp -r ServerStatus/web/* /home/wwwroot/default
+```
+
+四、运行服务端：
+web-dir参数为上一步设置的网站根目录，务必修改成自己网站的路径
+```
+./sergate --config=config.json --web-dir=/home/wwwroot/default
+```
+
+【客户端配置】（客户端程序在ServerStatus/clients下）：
+客户端有两个版本，client-linux为普通linux，client-psutil为跨平台版，普通版不成功，换成跨平台版即可。
+
+一、client-linux版配置：
+1、vim client-linux.py, 修改SERVER地址，username帐号， password密码
+2、python client-linux.py 运行即可。
+
+二、client-psutil版配置:
+1、安装psutil跨平台依赖库
+2、vim client-psutil.py, 修改SERVER地址，username帐号， password密码
+3、python client-psutil.py 运行即可。
+```
+### for Centos：
+sudo yum -y install epel-release
+sudo yum -y install python-pip
+sudo yum clean all
+sudo yum -y install gcc
+sudo yum -y install python-devel
+sudo pip install psutil
+### for Ubuntu/Debian:
+sudo root
+apt-get -y install python-setuptools python-dev build-essential
+apt-get -y install python-pip
+pip install psutil
+### for Windows:
+打开网址：https://pypi.python.org/pypi?:action=display&name=psutil#downloads
+下载psutil for windows程序包
+安装即可
+```
+
+打开云探针页面，就可以正常的监控。接下来把服务器和客户端脚本自行加入开机启动，或者进程守护，或以后台方式运行即可！例如： nohup python client-linux.py &
+
+# 为什么会有ServerStatus中文版：
+
+* 有些功能确实没用
+* 原版本部署，英文说明复杂
+* 不符合中文版的习惯
+* 没有一次又一次的轮子，哪来如此优秀的云探针

+ * parsing solutions.
+ *
+ * The program defines what arguments it requires, and `argparse` will figure
+ * out how to parse those out of `argc` and `argv`, it also automatically
+ * generates help and usage messages and issues errors when users give the
+ * program invalid arguments.
