sed '218 a{vm_memory_high_watermark, 0.9}' -i  rabbitmq.config  #內存設置

#rabbitmq數據是根據當前hostname做爲node節點做爲數據名保存、重啓會丟失用戶信息
echo 'NODENAME=rabbit@q' | sudo tee -a /etc/rabbitmq/rabbitmq-env.conf

查看rabbitmq的數據保存路徑 cat /var/lib/rabbitmq/mnesia/

service rabbitmq-server restart


其它命令：
rabbitmqctl list_users   #查看用戶信息
rabbitmqctl list_queues  #顯示隊列
rabbitmqctl  change_password  API  API123..   #修改用戶API密碼

rabbitmq配置 
通常狀況下，RabbitMQ的默認配置就足夠了。若是但願特殊設置的話，有兩個途徑：
一個是環境變量的配置文件 /etc/rabbitmq/rabbitmq-env.conf ；
一個是配置信息的配置文件 /etc/rabbitmq/rabbitmq.conf；
注意，這兩個文件默認是沒有的，若是須要必須本身建立。
管理web界面登錄
在瀏覽器中輸入http://127.0.0.1:15672/
輸入用戶名和密碼（默認爲guest）
