远程登陆linux且调用shell
首先在远程服务器上编写一个测试脚本test.sh,并赋予可执行权限:chmod +x test.sh
- #!/bin/bash
- echo 'test22'
- echo $1
$1是脚本传进来的第一个参数,我们控制台打印一下这个参数
新建maven项目,添加依赖:
- <dependency>
- <groupId>org.jvnet.hudson</groupId>
- <artifactId>ganymed-ssh2</artifactId>
- <version>build210-hudson-1</version>
- </dependency>
编写一个工具类:
- package com.xj.runshell;
- import java.io.IOException;
- import java.io.InputStream;
- import java.nio.charset.Charset;
- import ch.ethz.ssh2.Connection;
- import ch.ethz.ssh2.Session;
- public class RemoteShellTool {
- private Connection conn;
- private String ipAddr;
- private String charset = Charset.defaultCharset().toString();
- private String userName;
- private String password;
- public RemoteShellTool(String ipAddr, String userName, String password,
- String charset) {
- this.ipAddr = ipAddr;
- this.userName = userName;
- this.password = password;
- if (charset != null) {
- this.charset = charset;
- }
- }
- public boolean login() throws IOException {
- conn = new Connection(ipAddr);
- conn.connect(); // 连接
- return conn.authenticateWithPassword(userName, password); // 认证
- }
- public String exec(String cmds) {
- InputStream in = null;
- String result = "";
- try {
- if (this.login()) {
- Session session = conn.openSession(); // 打开一个会话
- session.execCommand(cmds);
- in = session.getStdout();
- result = this.processStdout(in, this.charset);
- session.close();
- conn.close();
- }
- } catch (IOException e1) {
- e1.printStackTrace();
- }
- return result;
- }
- public String processStdout(InputStream in, String charset) {
- byte[] buf = new byte[1024];
- StringBuffer sb = new StringBuffer();
- try {
- while (in.read(buf) != -1) {
- sb.append(new String(buf, charset));
- }
- } catch (IOException e) {
- e.printStackTrace();
- }
- return sb.toString();
- }
- /**
- * @param args
- */
- public static void main(String[] args) {
- RemoteShellTool tool = new RemoteShellTool("192.168.27.41", "hadoop",
- "hadoop", "utf-8");
- String result = tool.exec("./test.sh xiaojun");
- System.out.print(result);
- }
- }
main函数中执行了./test.sh xiaojun这个命令,控制台打印出:
test22
xiaojun
