linux安装rabbitMQ

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。

备注:
-d: 保证容器后台允许
-i:即使没连接,也要保持标准输入保持打开状态
-t:分配一个伪tty,一般与-i一起使用。
-e:设置rabbitmq的账户和密码变量

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

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。
