先自我介绍一下，小编浙江大学毕业，去过华为、字节跳动等大厂，目前阿里P7

深知大多数程序员，想要提升技能，往往是自己摸索成长，但自己不成体系的自学效果低效又漫长，而且极易碰到天花板技术停滞不前！

因此收集整理了一份《2024年最新大数据全套学习资料》，初衷也很简单，就是希望能够帮助到想自学提升又不知道该从何学起的朋友。

既有适合小白学习的零基础资料，也有适合3年以上经验的小伙伴深入学习提升的进阶课程，涵盖了95%以上大数据知识点，真正体系化！

由于文件比较多，这里只是将部分目录截图出来，全套包含大厂面经、学习笔记、源码讲义、实战项目、大纲路线、讲解视频，并且后续会持续更新

如果你需要这些资料，可以添加V获取：vip204888 （备注大数据）

[root@node1 ~]# curl http://node1:15672/cli/rabbitmqadmin -o /usr/sbin/rabbitmqadmin
[root@node1 ~]# chmod +x /usr/sbin/rabbitmqadmin

配置同步队列

[root@node1 ~]# rabbitmqadmin declare queue name=shared_queue
queue declared

rabbitmqctl set_policy [policy name(any name you like)] [Queue] [Mode]

[root@node1 ~]# rabbitmqctl set_policy ha-policy “shared_queue” ‘{“ha-mode”:“all”}’
Setting policy “ha-policy” for pattern “shared_queue” to “{“ha-mode”:“all”}” with priority “0” for vhost “/” …

查看同步状态

[root@node1 ~]# rabbitmqadmin list queues name node policy slave_nodes state synchronised_slave_nodes
±-------------±-------------±----------±--------------------------±--------±-------------------------+
| name | node | policy | slave_nodes | state | synchronised_slave_nodes |
