 # 手动安装教程：     
    
-【克隆代码】:
-```
-git clone https://github.com/cppla/ServerStatus.git
-```
+**【服务端配置】**           
           
-【服务端配置】（服务端程序在ServerStatus/web下）:  
-          
-一、生成服务端程序              
+#### 一、生成服务端程序              
 ```
-cd ServerStatus/server
-make
+`Debian/Ubuntu`: apt-get -y install gcc g++ make libcurl4-openssl-dev
+`Centos/Redhat`: yum -y install gcc gcc-c++ make libcurl-devel
+
+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                 
+#### 二、修改配置文件         
+```diff
+! watchdog rule 可以为任何已知字段的表达式。注意Exprtk库默认使用窄字符类型，中文等Unicode字符无法解析计算，等待修复       
+! watchdog interval 最小通知间隔
+! watchdog callback 可自定义为Post方法的URL，告警内容将拼接其后并发起回调    
+
+! Telegram: https://api.telegram.org/bot你自己的密钥/sendMessage?parse_mode=HTML&disable_web_page_preview=true&chat_id=你自己的标识&text=

-【客户端配置】（客户端程序在ServerStatus/clients下）：          
+**【客户端配置】**    
+
 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：       
+#### 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。      
+2、python3 client-linux.py 运行即可。      
 
-二、client-psutil版配置:                
+#### 二、client-psutil版配置:                
 1、安装psutil跨平台依赖库       
+```
+`Debian/Ubuntu`: apt -y install python3-pip && pip3 install psutil    
+`Centos/Redhat`: yum -y install python3-pip gcc python3-devel && pip3 install psutil      
+`Windows`: https://pypi.org/project/psutil/    
+```
 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
-```
+3、python3 client-psutil.py 运行即可。    
 
-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 &  
+服务器和客户端自行加入开机启动，或进程守护，或后台方式运行。 例如： nohup python3 client-linux.py &    
 
-### 如何快速跟随系统启动呢？其实好多人都搞复杂化了          
-1、chmod 755 /root/client-linux.py    
-2、vim /etc/crontab，尾部追加    
-```diff
-@reboot root /root/client-linux.py SERVER=$server USER=$user
-```

-# 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
