CentOS7下怎么搭建RabbitMQ(centos,rabbitmq,开发技术)

RabbitMQ是一种消息队列 ，用于常见的进程通信。支持点对点，请求应答和发布订阅模式 并且提供多种语言的支持。常见的java,c#，php都支持。

RabbitMQ 安装

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

度娘解析：主机hostname配置错误，原本hostname为vdevops.org,更改为vdevops，修改hosts文件中hostname设置

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~]#rabbitmqctladd_userlinuxprobepasswordCreatinguser"linuxprobe"......done.[root@vdevops~]#rabbitmqctllist_usersListingusers...guest[administrator]linuxprobe[]...done.#grantingadminroletoauserislikefollows[root@vdevops~]#rabbitmqctlchange_passwordlinuxprobestrongpasswordChangingpasswordforuser"linuxprobe"......done.#grantingadminroletoauserislikefollows[root@vdevops~]#rabbitmqctlset_user_tagslinuxprobeadministratorSettingtagsforuser"linuxprobe"to[administrator]......done.#deletingauserislikefollows[root@vdevops~]#rabbitmqctldelete_userlinuxprobeDeletinguser"linuxprobe"......done.

要使用RabbitMQ，也要添加虚拟主机

[root@vdevops~]#rabbitmqctladd_vhost/my_vhostCreatingvhost"/my_vhost"......done.[root@vdevops~]#rabbitmqctllist_vhostsListingvhosts...//my_vhost...done.[root@vdevops~]#rabbitmqctldelete_vhost/my_vhostDeletingvhost"/my_vhost"......done.

给虚拟主机的用户授予权限，请如下配置

#rabbitmqctlset_permissions[-pvhost][user][permission?(modify)(write)(read)][root@vdevops~]#rabbitmqctlset_permissions-p/my_vhostlinuxprobe".*"".*"".*"Settingpermissionsforuser"linuxprobe"invhost"/my_vhost"......done.#[root@vdevops~]#rabbitmqctllist_user_permissionslinuxprobeListingpermissionsforuser"linuxprobe".../my_vhost.*.*.*...done.#deletingpermissionofaspecificuserislikefollows[root@vdevops~]#rabbitmqctlclear_permissions-p/my_vhostlinuxprobeClearingpermissionsforuser"linuxprobe"invhost"/my_vhost"......done.

RabbitMQ：使用Web UI

[root@vdevops~]#rabbitmq-pluginsenablerabbitmq_managementThefollowingpluginshavebeenenabled:mochiwebwebmachinerabbitmq_web_dispatchamqp_clientrabbitmq_management_agentrabbitmq_managementPluginconfigurationhaschanged.RestartRabbitMQforchangestotakeeffect.[root@vdevops~]#systemctlrestartrabbitmq-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
