Java服务器检测与远程重启

第一步

•  在服务器上配置jre环境。
  
• 去oracle官网下载jre ，然后在环境变量里添加jre路径。

第二步

• 我使用的是PHPStudy集成环境
• 注册apache 和 mysql服务

#切换到相对应的目录 

#apache
apache httpd -k install -n "服务名"

#mysql
mysqld --install 服务名

• 写一个启动服务start .cmd 

cd /d C:\phpStudy\PHPTutorial\Apache\bin
net start apache

cd /d C:\phpstudy\PHPTutorial\MySQL\bin

net start mysql

• 需要写一个重启电脑的closeSystem.cmd
  

  shutdown -r -t 1

第三步

• 把start.cmd放到注册表的启动项中实现开机启动
• cmd输入以下命令  /v 后面是注册名 随意 路径改成相应的

#注册服务启动项 
reg add HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run /v add /d C:\regRun\start.cmd /f 

第四步

获取服务器信息类

package com.boolib.service;

import java.net.InetAddress;
import java.net.UnknownHostException;
import java.text.DecimalFormat;
import java.util.Properties;

public class MySystemInfo {
	private String osName;
	private String osArch;
	private String osVersion;
	private String address;
	private int totalMemoryJVM;
	private int idleMemoryJVM;
	private int totalMemory;
	private int maxMemory;
	private int idleMemory;
	private String use;

	InetAddress address1;
	Properties pro;
	String info;

	public MySystemInfo() {
		
		
		try {
			pro = System.getProperties();
			address1 = InetAddress.getLocalHost();
			this.osName = pro.getProperty("os.name");
			this.osArch = pro.getProperty("os.arch");
			this.osVersion = pro.getProperty("os.version");
			this.address = address1.getLocalHost().toString();
			this.totalMemoryJVM = (int)Runtime.getRuntime().totalMemory()/1024;
			this.maxMemory = (int)Runtime.getRuntime().maxMemory()/1024;
		} catch (UnknownHostException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

	}
	public int getIdleMemoryJVM() {
		return idleMemoryJVM;
	}
	public void setIdleMemoryJVM(int idleMemoryJVM) {
		this.idleMemoryJVM = idleMemoryJVM;
	}
	public String getUse() {
		return use;
	}
	public void setUse(String use) {
		this.use = use;
	}
	
        //获取服务器信息
	public MySystemInfo getInfo() {
		setIdleMemoryJVM( (int)Runtime.getRuntime().freeMemory()/1024);
		float d = (1-(float)this.idleMemoryJVM / (float)this.totalMemoryJVM)*100;
		DecimalFormat decimalFormat=new DecimalFormat(".00");
		use=decimalFormat.format(d)+"%";
                return this;
	}
	@Override
	public String toString() {
		return "服务器名称=" + osName + ", 服务器架构=" + osArch + ", 服务器版本号=" + osVersion + ",  IP地址="
				+  address.substring(address.lastIndexOf('/')+1) +  ", JVM空闲内存=" + idleMemoryJVM + ",  JVM总内存=" + totalMemoryJVM 
				+", 使用率"+use+"\n"
				;
	}

}

信息输出线程类

package com.boolib.service;

import java.io.BufferedReader;
import java.io.BufferedWriter;
import java.io.IOException;
import java.io.InputStreamReader;
import java.io.OutputStreamWriter;
import java.io.Reader;
import java.net.ServerSocket;
import java.net.Socket;


public class WriteSocket extends Thread{
	
	ServerSocket ssocket;
	Socket socket;
	BufferedReader reader;
	
	BufferedWriter writer;
	final int  PORT=65530;
	MySystemInfo mInfo ;
	String flag;

	public WriteSocket() {
		try {
			this.ssocket = new ServerSocket(PORT);
			this.mInfo= new MySystemInfo();
		
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

	@Override
	public void run() {
		try {
			this.socket = ssocket.accept();
		} catch (IOException e1) {
			// TODO Auto-generated catch block
			e1.printStackTrace();
		}
		while(true) {
			
		
		try {
		
			writer = new BufferedWriter(new OutputStreamWriter(socket.getOutputStream()));
			writer.write(mInfo.getInfo().toString());
			writer.flush();
			Thread.sleep(5000);
			
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (InterruptedException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}}
		
	}
	

}

信息接收线程类

package com.boolib.service;

import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStreamReader;
import java.net.ServerSocket;
import java.net.Socket;

public class ReadSocket extends Thread {
	
	
	BufferedReader reader;
	String flag;
	Socket socket;
	ServerSocket ssocket;
	final String cmd="C:\\closeSystem.cmd.lnk";
	public ReadSocket() {
		try {
			this.ssocket = new ServerSocket(65531);
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	
	}

	@Override
	public void run() {
		try {
			socket=	ssocket.accept();
			int i = 0 ;
			while(true)
			{
				i++;
				reader = new BufferedReader(new InputStreamReader(socket.getInputStream())) ;
				System.out.println("当前第"+i+"次接收");
				if((flag=reader.readLine())!=null) {
				
					if(flag.equals("shutdown"))
					{
						
						  ProcessBuilder pb = new ProcessBuilder("cmd","/c",cmd); 
						  Process process = pb.start(); 
						   
						  //Runtime.getRuntime().exec("C:\\Users\\xu\\Desktop\\stop.cmd.lnk");
						  System.out.println("命中红心");
						  break;
					}
					
				}
			
				
				Thread.sleep(500);
			}
			
			
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		} catch (InterruptedException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	
	}
	

}

这里我设置的服务器监听端口是tcp :65530,65531,需要在服务器上安全组上配置

启动类

package com.boolib.service;

public class Start {

	public static void main(String[] args) {
		new ReadSocket().start();
		new WriteSocket().start();
	}
}

生成jar包，传送至服务器。写启动项

#注册监听项reg add HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run /v socket /d C:\regRun\utils\socketjar.cmd /f

测试 可以用telnet  ip 端口号 获取writer

服务器设置成自动登录

搜索 ：control userpasswords2；

测试自动重启类

package com.boolib.test;

import java.io.BufferedWriter;
import java.io.IOException;
import java.io.OutputStreamWriter;
import java.net.Socket;

public class test {
	
	public static void main(String[] args) {
		String path = "你的域名或者ip";
		try {
			Socket so =new Socket(path, 65531);
			BufferedWriter bw = new BufferedWriter(new OutputStreamWriter(so.getOutputStream()));
			bw.write("shutdown");
			bw.write("\n");
			bw.flush();
			so.shutdownOutput();//此处必须写
			
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

}
