linux安装rabbitMQ

Posted 2022-10-13

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。

[root@manager1 home]# docker pull rabbitmq:3.10-management #拉取最新的镜像
[root@manager1 home]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE

rabbitmq 3.10-management 6b94498c1b2f 3 weeks ago 262MB

[root@manager1 home]# docker run -d -it --name rabbitmq -e RABBITMQ_DEFAULT_USER=admin -e RABBITMQ_DEFAULT_PASS=123456 -p 5672:5672 -p 15672:15672 rabbitmq:3.10-management #运行容器
3812306d62b01cd31722fd762704844375e7b801ea42d579deffa8c917f9fb84

[root@manager1 home]# docker ps #查看运行起来的容器
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
3812306d62b0 rabbitmq:3.10-management "docker-entrypoint.s…" 2 seconds ago Up 2 seconds 4369/tcp, 5671/tcp, 0.0.0.0:5672->5672/tcp, 15671/tcp, 15691-15692/tcp, 25672/tcp, 0.0.0.0:15672->15672/tcp rabbitmq

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​

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。
