CentOS7下安装RabbitMQ

第一步下载erlang环境并安装：

rpm -uvh https://mirrors.aliyun.com/centos/7.6.1810/extras/x86_64/packages/epel-release-7-11.noarch.rpm

yum install erlang

第二步下载rabbitmq的rpm包并安装：

wget http://www.rabbitmq.com/releases/rabbitmq-server/current/rabbitmq-server-3.6.15-1.el7.noarch.rpm

yum install rabbitmq-server-3.6.15-1.el7.noarch.rpm

第四步打开rabbitmq管理web：rabbitmq-plugins enable rabbitmq_management

默认3.3.0开始不允许guest账户非本地登录，需要修改以下设置

/usr/lib/rabbitmq/lib/rabbitmq_server-3.6.15/ebin/rabbit.app

将：{loopback_users, [<<”guest”>>]}，
改为：{loopback_users, []} 然后重启服务 systemctl restart rabbitmq-server

打开rabbitmq的端口：

firewall-cmd --zone=public --add-port=5672/tcp --permanent

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

firewall-cmd --reload
