1、Ubuntu默认未添加Rabbit源，需要添加源
nemo@Cynthia:~$ sudo vim /etc/apt/sources.list
添加：deb http://www.rabbitmq.com/debian/testing main
保存后执行更新
nemo@Cynthia:~$ sudo apt-get update
2、下载rabbitmq
nemo@Cynthia:~$ sudo apt-get install rabbitmq-server
如果在安装中出现无法下载的错误，需要将rabbitMQ的公钥添加到信任列表中：
wget http://www.rabbitmq.com/rabbitmq-signing-key-public.asc apt-key add rabbitmq-signing-key-public.asc
mq
