xz -d rabbitmq-server-generic-unix-3.6.12.tar.xz
tar -xvf rabbitmq-server-generic-unix-3.6.12.tar -C /opt
- 命名
cd /opt
mv rabbitmq_server-3.6.12 rabbitmq
- 環境變量

** 重新加載
source /etc/profile
- web插件
rabbitmq-plugins enable rabbitmq_management
- 開放防火墻
firewall-cmd --zone=public --add-port=5672/tcp --permanent
firewall-cmd --zone=public --add-port=15672/tcp --permanent
firewall-cmd --reload
- 后臺運行
rabbitmq-server -detached
-detached 參數是為了能夠讓rabbitmq服務以守護的方式在后臺運行,不會因為當前的shell窗口關閉而影響
- 啟動服務
rabbitmq 安裝后默認不是以后臺進程的方式啟動的，要想使 rabbitmq 在系統啟動時默認以后臺進程的方式啟動，請以管理員身份執行以下命令：
chkconfig rabbitmq-server on
- 停止
rabbitmqctl stop
-
訪問

用戶名密碼都是guest/guest
發現登錄不了
這個帳戶有限制,默認只能在本地網絡(localhost),遠程網絡訪問受限,添加一個用戶
image.png
- 添加用戶
rabbitmqctl add_user root root
用戶名密碼都 是root
- 設置權限 為adminstrator
rabbitmqctl set_permissions -p / root ".*" ".*" ".*"
- 設置root 為管理員角色
rabbitmqctl set_user_tags root administrator
