Java远程执行Shell命令
需要ganymed-ssh2-build210.jar
1 连接
Connection conn = new Connection(ip地址, 端口号);
conn.connect();
2认证并判断
boolean isAuthenticated = conn.authenticateWithPassword(用户名, 密码);
if (isAuthenticated == false){
System.out.println("密码错误");
throw new IOException("Authentication failed.");
}
3打开一个Session
final Session session=conn.openSession();
4上传文件(根据情况)
SCPClient client = new SCPClient(conn);
client.put(updateFileBytes, "xlsbz_server.zip", "/app/mhfx/");
5执行Shell命令(一般放线程里执行)
new Thread(new Runnable() {
public void run() {
try {
session.requestDumbPTY(); //建立虚拟终端
session.startShell(); //打开一个shell
OutputStream fout = session.getStdin(); //也可以用PrintWriter out = new PrintWriter(session.getStdin());
//输入命令
fout.write(("bash xlsbz_server/bin/telnet.sh" + "\n").getBytes());
Thread.sleep(1000);
fout.write(("freeze" + "\n").getBytes());
Thread.sleep(60000);
fout.write(("quit" + "\n").getBytes());
Thread.sleep(1000);
fout.write(("bash xlsbz_server/bin/xlsbz.sh" + "\n").getBytes());
Thread.sleep(1000);
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}).start();
6关闭session和相应流
session.close();
Thread.sleep(1000);
conn.close();
Thread.sleep(1000);
补充一点:
有时候需要从远程服务器获取返回结果
final InputStream is = new StreamGobbler(session.getStdout()); //StreamGobbler的作用是把session的标准输出包装成InputStream,用于接收目标服务器上的控制台返回结果,读取br中的内容。然后在循环中,把每一行的内容添加到StringBuffer里面。
new Thread() {
public void run() {
BufferedReader br = new BufferedReader(new InputStreamReader(is));
while (true) {
try {
String line = br.readLine();
if (line == null) break;
System.out.println(line);
} catch (IOException e) {
e.printStackTrace();
}
}
try {
is.close();
br.close();
} catch (IOException e) {
e.printStackTrace();
}
}
}.start();
