CentOS7下安裝rabbitMQ的簡單方法
安裝erlang
普及一下，rabbitMQ是用erlang語言進行開發的，因此需要安裝語言包。
安裝erlang
$ wget https://bintray.com/rabbitmq-erlang/rpm/download_file?file_path=erlang%2F22%2Fel%2F6%2Fx86_64%2Ferlang-22.3.1-1.el6.x86_64.rpm
$ rpm -ivh erlang-22.3.1-1.el6.x86_64.rpm --replacefiles
安裝rabbitmq-server
$ wget https://github.com/rabbitmq/rabbitmq-server/releases/download/v3.8.3/rabbitmq-server-3.8.3-1.el7.noarch.rpm
$ rpm -ivh rabbitmq-server-3.8.3-1.el7.noarch.rpm
