java连接ssh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：
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
这个简单的远程调用shell demo就算完了。
