rabbitmq-server启动报错：Failed to start RabbitMQ broker

防火墙设置
[root@linuxprobe~]# firewall-cmd --add-port=5672/tcp --permanentsuccess [root@linuxprobe~]# firewall-cmd --reloadsuccess
要使用RabbitMQ，请先添加用户
[root@vdevops ~]# rabbitmqctl add_user linuxprobe passwordCreating user "linuxprobe" ... ...done. [root@vdevops ~]# rabbitmqctl list_usersListing users ... guest [administrator] linuxprobe [] ...done.# granting admin role to a user is like follows[root@vdevops ~]# rabbitmqctl change_password linuxprobe strongpasswordChanging password for user "linuxprobe" ... ...done.# granting admin role to a user is like follows[root@vdevops ~]# rabbitmqctl set_user_tags linuxprobe administratorSetting tags for user "linuxprobe" to [administrator] ... ...done.# deleting a user is like follows[root@vdevops ~]# rabbitmqctl delete_user linuxprobeDeleting user "linuxprobe " ... ...done.
要使用RabbitMQ，也要添加虚拟主机
[root@vdevops ~]# rabbitmqctl add_vhost /my_vhostCreating vhost "/my_vhost" ... ...done. [root@vdevops ~]# rabbitmqctl list_vhostsListing vhosts ... / /my_vhost ...done. [root@vdevops ~]# rabbitmqctl delete_vhost /my_vhostDeleting vhost "/my_vhost" ... ...done.
给虚拟主机的用户授予权限，请如下配置
# 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 linuxprobeListing permissions for user "linuxprobe" ... /my_vhost .* .* .* ...done.# deleting permission of a specific user is like follows[root@vdevops ~]# rabbitmqctl clear_permissions -p /my_vhost linuxprobeClearing permissions for user "linuxprobe" in vhost "/my_vhost" ... ...done.
RabbitMQ：使用Web UI
[root@vdevops ~]# rabbitmq-plugins enable rabbitmq_managementThe 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
客户端访问
http://vdevops:15672/
rabbitmqadmin使用
可以配置RabbitMQ使用rabbitmqadmin命
在Web UI上下载rabbitmqadmin。 登录到Web UI并移动到“http：//（主机名或IP地址）：15672 / cli”，然后显示以下屏幕，您可以在这里下载rabbitmqadmin，点击here右键保存rabbitmqadmin.txt，然后上传到服务器上面更改为rabbitmqadmin，并添加执行权限
将rabbitmqadmin上传到RabbitMQ服务器并设置合适的权限，此示例显示如下设置
[root@localhost ~]# ll /usr/local/bin/rabbitmqadmin-rwxr-xr-x. 1 root root 36112 Nov 11 17:23 /usr/local/bin/rabbitmqadmin [root@vdevops bin]# rabbitmqadmin list users+------------+------------------------------+---------------+ | name | password_hash | tags | +------------+------------------------------+---------------+ | guest | k2rhpzCrZBKkY5WRhUWrGm5DCkg= | administrator | | linuxprobe | P+YxK1QXIYrJpek5i//rPjn5SME= | administrator | +------------+------------------------------+---------------+ [root@vdevops bin]# cd[root@vdevops ~]# rabbitmqadmin list users+------------+------------------------------+---------------+ | name | password_hash | tags | +------------+------------------------------+---------------+ | guest | k2rhpzCrZBKkY5WRhUWrGm5DCkg= | administrator | | linuxprobe | P+YxK1QXIYrJpek5i//rPjn5SME= | administrator | +------------+------------------------------+---------------+ [root@vdevops ~]# rabbitmqadmin list vhosts+-----------+---------+ | name | tracing | +-----------+---------+ | / | False | | /my_vhost | False | +-----------+---------+
