java远程登录linux并调用shell命令
java程序用ssh远程登录linux并调用shell命令，需要用到java的ssh客户端，这里使用的是JSch，支持ssh2
示例代码登录远程linux，返回远程目录中的所有文件
JSch jsch = new JSch();try {Session 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 channel = session.openChannel("exec");ChannelExec execChannel = (ChannelExec)channel;execChannel.setCommand("ls");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(sb.toString());channel.disconnect();session.disconnect();} catch (JSchException e) {e.printStackTrace();} catch (IOException e) {e.printStackTrace();}}
