java连接centos服务器，并执行命令

atcmahoder

java连接需要用到ganymed-ssh2。
将 ganymed-ssh2-build210.jar 加入到项目的lib中
package com.jms;
import java.io.BufferedReader;
import java.io.IOException;
import java.io.InputStream;
import java.io.InputStreamReader;
import ch.ethz.ssh2.Connection;
import ch.ethz.ssh2.Session;
import ch.ethz.ssh2.StreamGobbler;
public class Test {
/**
* @param args
* @throws IOException
*/
public static void main(String[] args) throws Exception {
// TODO Auto-generated method stub
System.out.println("开始连接主机");
Connection conn = new Connection("localhost", 22);
conn.connect();
boolean isdenglu = conn
.authenticateWithPassword("root", "123456");
if (isdenglu) {
System.out.println("ssh2登陆成功");
} else {
System.out.println("登陆失败");
}
System.out.println("当前目录：");
Session ses = conn.openSession();
ses.execCommand("pwd");
InputStream stdout = new StreamGobbler(ses.getStdout());
BufferedReader br = new BufferedReader(new InputStreamReader(stdout));
while (true)      
{      
String line = br.readLine();      
if (line == null)      
break;      
System.out.println(line);      
}   
System.out.println("运行结果："+ses.getExitStatus());
ses.close();
conn.close();
}
}

开始连接主机
ssh2登陆主机成功
当前目录：
/root
运行结果：0
