rabbitmq-server啟動報錯：Failed to start RabbitMQ broker

度娘解析：主機hostname配置錯誤，原本hostname為vdevops.org,更改為vdevops，修改hosts文件中hostname設(shè)置

防火墻設(shè)置

[root@linuxprobe~]# firewall-cmd --add-port=5672/tcp --permanent success [root@linuxprobe~]# firewall-cmd --reload success

要使用RabbitMQ，請先添加用戶

[root@vdevops ~]# rabbitmqctl add_user linuxprobe password Creating user "linuxprobe" ... ...done. [root@vdevops ~]# rabbitmqctl list_users Listing users ... guest [administrator] linuxprobe [] ...done. # granting admin role to a user is like follows [root@vdevops ~]# rabbitmqctl change_password linuxprobe strongpassword Changing password for user "linuxprobe" ... ...done. # granting admin role to a user is like follows [root@vdevops ~]# rabbitmqctl set_user_tags linuxprobe administrator Setting tags for user "linuxprobe" to [administrator] ... ...done. # deleting a user is like follows [root@vdevops ~]# rabbitmqctl delete_user linuxprobe Deleting user "linuxprobe " ... ...done.

要使用RabbitMQ，也要添加虛擬主機

[root@vdevops ~]# rabbitmqctl add_vhost /my_vhost Creating vhost "/my_vhost" ... ...done. [root@vdevops ~]# rabbitmqctl list_vhosts Listing vhosts ... / /my_vhost ...done. [root@vdevops ~]# rabbitmqctl delete_vhost /my_vhost Deleting vhost "/my_vhost" ... ...done.

給虛擬主機的用戶授予權(quán)限，請如下配置

# rabbitmqctl set_permissions [-p vhost] [user] [permission ? (modify) (write) (read)] [root@vdevops ~]# rabbitmqctl set_permissions -p /my_vhost linuxprobe ".*" ".*" ".*" Setting permissions for user "linuxprobe" in vhost "/my_vhost" ... ...done. # [root@vdevops ~]# rabbitmqctl list_user_permissions linuxprobe Listing permissions for user "linuxprobe" ... /my_vhost .* .* .* ...done. # deleting permission of a specific user is like follows [root@vdevops ~]# rabbitmqctl clear_permissions -p /my_vhost linuxprobe Clearing permissions for user "linuxprobe" in vhost "/my_vhost" ... ...done.

RabbitMQ：使用Web UI

[root@vdevops ~]# rabbitmq-plugins enable rabbitmq_management The following plugins have been enabled: mochiweb webmachine rabbitmq_web_dispatch amqp_client rabbitmq_management_agent rabbitmq_management Plugin configuration has changed. Restart RabbitMQ for changes to take effect. [root@vdevops ~]# systemctl restart rabbitmq-server

rabbitmqadmin使用

可以配置RabbitMQ使用rabbitmqadmin命

在Web UI上下載rabbitmqadmin。 登錄到Web UI并移動到“http：//（主機名或IP地址）：15672 / cli”，然后顯示以下屏幕，您可以在這里下載rabbitmqadmin，點擊here右鍵保存rabbitmqadmin.txt，然后上傳到服務(wù)器上面更改為rabbitmqadmin，并添加執(zhí)行權(quán)限

將rabbitmqadmin上傳到RabbitMQ服務(wù)器并設(shè)置合適的權(quán)限，此示例顯示如下設(shè)置
