Linux下RabbitMQ详细安装流程

本文章选取的服务器 *** 作系统：CentOS 7版本；

在 /etc/yum.repos.d/ 目录下添加 .repo 文件（例如：rabbitmq-erlang.repo），因发行版的不同，文件内容也有区别，以下是Centos 7 的配置：

在 /etc/yum.repos.d/ 目录下添加 .repo 文件（例如：rabbitmq.repo），因发行版的不同，文件内容也有区别，以下是Centos 7 的配置：

进入 /etc/systemd/system 或者/usr/lib/systemd/system，并创建rabbitmq-server.service 文件。

注意：通过 yum 安装的，已经在 /usr/lib/systemd/system 目录下存在rabbitmq-server.service 文件。

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

[root@vdevops /]# hostnamectl set-hostname vdevops # hostname更改重启启动rabbitmq-server

要使用RabbitMQ，请先添加用户

[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

# deleting a user is like follows

[root@vdevops ~]# rabbitmqctl delete_user linuxprobe

Deleting user "linuxprobe " ...

...done.

要使用RabbitMQ，也要添加虚拟主机

[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.

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 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

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
