由於需要遠程監控一些Linux主機的運行情況,需要通過java遠程執行一些shell腳本,並獲取返回值,可以通過jsch實現
jsch jar包下載地址:http://sourceforge.net/projects/jsch/files/jsch.jar/0.1.51/jsch-0.1.51.jar/download
public static void SSHCommand(String host,String user,String pass,int port,String command){ JSch jsch = new JSch(); Session session=null; Channel channel=null; try { session = jsch.getSession(user, host, port); session.setPassword(pass); session.setTimeout(2000); Properties config = new Properties(); config.put("StrictHostKeyChecking", "no"); session.setConfig(config); session.connect(); channel = session.openChannel("exec"); ChannelExec execChannel = (ChannelExec)channel; execChannel.setCommand(command); InputStream in = channel.getInputStream(); channel.connect(); StringBuffer sb = new StringBuffer(); int c = -1; while((c = in.read()) != -1){ sb.append((char)c); } System.out.println("輸出結果是:"+sb.toString()); in.close(); } catch (JSchException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } finally{ channel.disconnect(); session.disconnect(); } }
當然還可以通過sftp上傳文件
public static boolean upload(String host, String username, String password, int port, String location,File uploadFile){ Session session; Channel channel; Channel channelExec; JSch jsch = new JSch(); try { session = jsch.getSession(username, host, port); session.setPassword(password); Properties config = new Properties(); config.put("StrictHostKeyChecking", "no"); session.setConfig(config); session.connect(); channel = session.openChannel("sftp"); channel.connect(); ChannelSftp c = (ChannelSftp)channel; c.cd(location); c.put(new FileInputStream(uploadFile),uploadFile.getName()); //------------------------- c.disconnect(); session.disconnect(); return true; } catch (JSchException e) { e.printStackTrace(); } catch (SftpException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } return false; }
