注意，这里出现config file(s) : /etc/rabbitmq/rabbitmq.config (not found)

这里显示的是没有找到配置文件，我们可以自己创建这个文件

1
2
cd /etc/rabbitmq/
vi rabbitmq.config
编辑内容如下
1
[{rabbit, [{loopback_users, []}]}].

后面的“.”是要的，不是写错
这里的意思是开放使用，rabbitmq默认创建的用户guest，密码也是guest，这个用户默认只能是本机访问，localhost或者127.0.0.1，从外部访问需要添加上面的配置。

保存配置后重启服务

service rabbitmq-server stop
service rabbitmq-server start

开放 15672 端口

这里虚拟机操作，没有机子没装防火墙，固做记录未亲测

firewall-cmd --zone=public --add-port=15672/tcp --permanent
firewall-cmd --reload 

# 直接关闭防火墙
service iptables stop

RabbitMQ无法访问Web管理页面

启动RabbitMQ后，没法访问Web管理页面，RabbitMQ安装后默认是不启动管理模块的，所以需要配置将管理模块启动

3
rabbitmqctl start_app
rabbitmq-plugins enable rabbitmq_management
rabbitmqctl stop

设置 RabbitMQ 远程 IP 登陆 (以下操作不需要重启)

rabbitmq默认创建的用户guest，密码也是guest

  1. 创建一个 anan 的账号

    1
    rabbitmqctl add_user anan 123456

  2. 设置用户角色

    1
    rabbitmqctl set_user_tags anan  administrator

  3. 设置用户权限

    1
    rabbitmqctl set_permissions -p "/" anan ".*" ".*" ".*"

  4. 设置完成后可以查看当前用户和角色（需要开启服务）

    1
    rabbitmqctl list_users
