linux 已经安装好docker环境。​

rabbitMQ是一个消息队列软件

rabbitMQ的特性：消息持久化：从内存持久化消息到硬盘，再从硬盘加载到内存。

增加备注：​

查看rabbitmq当前用户列表​

[root@manager1 home]# docker exec -it rabbitmq /bin/bash #进入rabbitmq容器​

root@3812306d62b0:/# rabbitmqctl list_users #查看当前用户列表​

Listing users ...​

usertags​

admin[administrator]​


root@3812306d62b0:/# rabbitmqctl change_password admin '12345678' #修改密码​

Changing password for user "admin" ...​

修改密码后，rabbitMQ 的web界面会弹出重新输入账号和密码​

rabbitMQ官网：​​https://www.rabbitmq.com/#features​​​

rabbitmq端口说明

5672 ：这是rabbitMQ的端口号;

15672 ：这是那个RabbitMQ的web页面的端口号;

问题1：​

linux内存不足导致rabbitMQ容器自动退出​

rabbitMQ日志如下​

rabbitMQ的特性：消息持久化：从内存持久化消息到硬盘，再从硬盘加载到内存。所以查看一下内存，发现swap的内存空间也用完了。后面给服务器增加内存，重新运行rabbitmq容器。
