开发需求: 因系统程序部署时,经常是拆分部署(多台机器) ,手工部署费时费力,且每次都要手工配置系统参数(系统提供配置向导)。
如下图所示:
1)进行main容器 -> 2)执行系统配置向导 -> 3)选择服务器模式 -> 4) 选择web控制台….然后进行具体的服务器IP设置。
为了解放双手，用java实现了Linux(centos) 下docker 应用程序的命令交互。
具体代码如下:
import java.io.*; /** * @author by dujiajun * @date 2021/4/29. */public class TestMain extends Thread{ //进入docker main private static String [] cmds = {"docker","exec","-i","main","bash"}; private Process pro; //初始化各机器IP信息 private String role = ""; private String webIp = ""; private String redisIp = ""; private String beanstalkdIp = ""; private String pgIp = ""; //main应用重启 public static String [] cmdRestart = {"/bin/sh","-c","docker restart main"}; public void cmdRun(String[] machines) throws Exception { //执行xx系统配置向导命令并生成进程 //pro = Runtime.getRuntime().exec(cmds); ProcessBuilder pb = new ProcessBuilder(cmds); /* pb.inheritIO(); pb.redirectErrorStream(true);*/ pro = pb.start(); System.out.println("执行前pro1:" + pro.isAlive()); //解析machines信息 if (machines.length > 0) { for (int i = 0; i < machines.length; i++) { int strEndIndex = machines[i].indexOf(":"); String str = machines[i].substring(0, strEndIndex); String content = machines[i].substring(strEndIndex + 1); switch (str.trim()) { case "role": role = content; break; //web服务器IP case "webIp": webIp = content; break; //redis服务器IP case "redisIp": redisIp = content;

} } //查看进程是否还存活 System.out.println("pro3:" + pro.isAlive()); bw.flush();//缓存提交 System.out.println("缓存提交!"); bw.close(); System.out.println(" bw.close();"); System.out.println("web配置向导设置成功!"); } else if (role != null && role.equals("api-server")) {//系统app应用 //系统配置向导命令集-APP System.out.println("*********进入APP服务器控制台配置向导*********"); String[] strCmdApp = { "python /opt/tools/skylar_cli/bin/skylar_cli.pyc",//系统配置向导 "server-type", //服务器模式 "api-server", //APP服务器 "cache-info " + redisIp + ":6379", //缓存服务器 "db-info " + pgIp + ":5432", //设置数据库信息 "queue-info " + beanstalkdIp + ":11300", //设置队列信息 "web-server-info " + webIp + ":8080", //设置管理服务器端口 "commit",//提交配置 "exit" };

bw.flush();//缓存提交 System.out.println("缓存提交!"); System.out.println("日志分析服务器配置向导设置成功!"); bw.close(); } } catch (IOException | InterruptedException e) { //pro.destroyForcibly(); e.printStackTrace(); //pro.destroy(); System.out.println("e.getMessage(): " + e.getMessage()); } finally { try { Process process = Runtime.getRuntime().exec(cmdRestart);//重启main System.out.println("process.isAlive:" + process.isAlive()); System.out.println("重启main成功!"); } catch (IOException e) { e.printStackTrace(); } } } }.start(); new Thread(){ public void run(){ BufferedReader br = new BufferedReader(new InputStreamReader(pro.getErrorStream())); String cmdout = ""; try { cmdout = br.readLine(); while(cmdout!= null&&(!cmdout.equals("exit"))){ System.out.println(cmdout); } } catch (IOException e) { //System.out.println("br:pro.destroy();"); //pro.destroy(); e.printStackTrace(); System.out.println("e.printStackTrace();"); } try { System.out.println(" br.close();"); br.close(); } catch (IOException e) { e.printStackTrace(); } } }.start(); pro.waitFor();//进程等待 } public static void main(String[] args) throws Exception { TestMain testMain = new TestMain(); /* //测试用 String[] machines ={ "role:web-server", "webIp:xx.xx.xx.110", "redisIp:xx.xx.xx.211", "beanstalkdIp:xx.xx.xx.211", "pgIp:xx.xx.xx.212" };*/ testMain.cmdRun(args); /* System.exit(0); System.out.println("System.exit(0);");*/ }}
特别注意:
private static String [] cmds = {"docker","exec","-i","main","bash"};
一定要使用 docker exec -i main bash ，不要使用 -it ，否则会报错 cannot enable tty mode on non tty input。
Usage: docker exec [OPTIONS] CONTAINER COMMAND [ARG...] Run a command in a running container -i, --interactive=false Keep STDIN open even if not attached -t, --tty=false Allocate a pseudo-TTY
打成jar包，执行jar包：
终于看到久违的部署成功界面~
