rokcetmq-console启动失败踩坑

搭建 rocketmq-console 的时候，控制台一直报错。

[2019-09-23 19:42:14.004] ERROR op=global_exception_handler_print_error
org.apache.rocketmq.console.exception.ServiceException: This date have't data!
        at org.apache.rocketmq.console.service.impl.DashboardCollectServiceImpl.getBrokerCache(DashboardCollectServiceImpl.java:140)

然后打开 rocketmq-console源码查看。

DashboardCollectServiceImpl.java

@Override
   public Map<String, List<String>> getBrokerCache(String date) {
       String dataLocationPath = rmqConfigure.getConsoleCollectData();
       File file = new File(dataLocationPath + date + ".json");
       if (!file.exists()) {
           throw Throwables.propagate(new ServiceException(1, "This date have't data!"));
       }
       return jsonDataFile2map(file);
   }

错误就是这里抛出的了。

1	String dataLocationPath = rmqConfigure.getConsoleCollectData();

这里获取配置文件路径

所以去 resources/application.properties 下查找，

1	rocketmq.config.dataPath=/tmp/rocketmq-console/data

知道了路径，接着去部署rocketmq的服务器查看

[root@localhost data]# pwd
/tmp/rocketmq-console/data

[root@localhost data]# ll
total 16
-rw-r--r--. 1 root root  1759 Sep 23 19:58 dashboard2019-09-23.json
-rw-r--r--. 1 root root 11864 Sep 23 19:58 dashboard2019-09-23_topic.json

发现有数据，但是仔细一看，日期对不上。当时的日期是 2019-09-25

查看服务器时间：

[root@localhost data]# date
Mon Sep 23 19:59:41 UTC 2019
[root@localhost data]# date -R
Mon, 23 Sep 2019 20:00:58 +0000

果然时间错了，时区并不是东八区

将时区改为东八区，请自行 goolge/百度

如果还是不对，则将时间改为当前时间，参考：https://blog.csdn.net/YonJarLuo/article/details/77864321

重新执行 jar包，

1	java -jar rocketmq-console-ng-1.0.1.jar

[root@localhost data]# pwd
/tmp/rocketmq-console/data

[root@localhost data]# ll
total 40
-rw-r--r--. 1 root root  2479 Sep 24 04:26 dashboard2019-09-23.json
-rw-r--r--. 1 root root 19208 Sep 24 04:26 dashboard2019-09-23_topic.json
-rw-r--r--. 1 root root     2 Sep 25 00:00 dashboard2019-09-24.json
-rw-r--r--. 1 root root     2 Sep 25 00:00 dashboard2019-09-24_topic.json
-rw-r--r--. 1 root root   127 Sep 25 16:52 dashboard2019-09-25.json
-rw-r--r--. 1 root root   632 Sep 25 16:52 dashboard2019-09-25_topic.json

查看后台，没有了报错，一切恢复了正常~
