Centos7.6 之 Rabbitmq 安装

关于消息队列的知识网上有很多讲解的，这里就不再讲解了，由于项目的需要，共多个项目之间进行数据交换等，需要用到消息队列，进行监听。

安装步骤

Rabbitmq 是依赖Erlang 语言包，需要先按照Erlang ,这里采用RPM 进行安装，先下载对应的数据包

[dataman@iZm5e400nzm6ck0cz0u32aZ soft]$ wget -c https://packagecloud.io/rabbitmq/erlang/packages/el/7/erlang-20.3-1.el7.centos.x86_64.rpm/download.rpm

[dataman@iZm5e400nzm6ck0cz0u32aZ soft]$ wget -c https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.7.14/rabbitmq-server-3.7.14-1.el7.noarch.rpm

安装Erlang

[dataman@iZm5e400nzm6ck0cz0u32aZ soft]$ rpm -ivh download.rpm 

安装rabbitmq

[dataman@iZm5e400nzm6ck0cz0u32aZ soft]$ sudo rpm -ivh rabbitmq-server-3.7.14-1.el7.noarch.rpm 
warning: rabbitmq-server-3.7.14-1.el7.noarch.rpm: Header V4 RSA/SHA256 Signature, key ID 6026dfca: NOKEY
error: Failed dependencies:
	socat is needed by rabbitmq-server-3.7.14-1.el7.noarch

缺少socat

[dataman@iZm5e400nzm6ck0cz0u32aZ soft]$ sudo yum install socat

然后再次安装

[dataman@iZm5e400nzm6ck0cz0u32aZ soft]$ sudo rpm -ivh rabbitmq-server-3.7.14-1.el7.noarch.rpm 
warning: rabbitmq-server-3.7.14-1.el7.noarch.rpm: Header V4 RSA/SHA256 Signature, key ID 6026dfca: NOKEY
