這種問題用戶沒有權(quán)限需要 添加權(quán)限
添加權(quán)限有兩種
- 在dos命令中設(shè)置
rabbitmqctl set_permissions -p / guest '.* ' ' .* ' '.*'
顯示Setting permissions for user "guest" in vhost "/" 表明設(shè)置權(quán)限成功
2.在后臺(tái)控制臺(tái)輸入
輸入前需要添加rabbit的插件
后臺(tái)管理開啟方法
rabbitmq-plugins enable rabbitmq_management
重啟rabbitmq服務(wù)生效
打開http://localhost:15672/即可看到管理后臺(tái)
用戶名密碼均為guest
輸入http://127.0.0.1:15672進(jìn)入后臺(tái)
找到你自己的用戶
點(diǎn)擊名字
輸入框中內(nèi)容如圖所示即可。
ShutdownSignalException: channel error; protocol method: #method<channel.close>(reply-code=406, reply-text=PRECONDITION_FAILED - inequivalent arg 'durable' for queue 'order-delay-queue' in vhost '/': received 'false' but current is 'true', class-id=50, method-id=10)
表示你order-delay-queue隊(duì)列，已經(jīng)創(chuàng)建運(yùn)行，但是你告訴rabbit的是它沒有創(chuàng)建。原因在于‘
需要將此隊(duì)列刪除并且對(duì)應(yīng)代碼為
代碼rabbit官方文檔中有
2.延時(shí)隊(duì)列報(bào)錯(cuò)
ShutdownSignalException: connection error; protocol method: #method<connection.close>(reply-code=503, reply-text=COMMAND_INVALID - unknown exchange type 'x-delayed-message', class-id=40, method-id=10)
代表沒有找到對(duì)應(yīng)x-delayed-message的exchange type
rabbit官方github地址
說明你要是用延時(shí)隊(duì)列需要啟用插件
首先在dos命令中輸入文檔中的命令顯示error(錯(cuò)誤信息為沒有發(fā)現(xiàn)對(duì)應(yīng)插件)則需要到rabbit官網(wǎng)下載插件
插件地址
找到這個(gè)插件
下載下來冰晶插件復(fù)制到rabbit-service的插件目錄(自己的安裝目錄)中
并且在dos命令中再次運(yùn)行
rabbitmq-plugins enable rabbitmq_delayed_message_exchange
就可以了
3. error: unable to connect to node rabbit@: nodedown
rabbitmq版本過低問題
當(dāng)前有些阿里云服務(wù)器阿里源對(duì)應(yīng)的rabbit的版本為3.5.X版本，但現(xiàn)在官網(wǎng)延遲插件對(duì)應(yīng)的最低版本為3.6.X
解決方案：
- 手動(dòng)安裝最新版（如果不想手動(dòng)則使用第二種）
- 添加源 echo 'deb http://www.rabbitmq.com/debian/ testing main' | tee /etc/apt/sources.list.d/rabbitmq.list 然后執(zhí)行 apt-get update 會(huì)安裝3.6.15的版本
