需要安装的操作系统信息:

[root@m161p114 ~]#
本文选择最新版本的RabbitMQ 3.9.8。现在rabbitMQ的下载文件都放在了github。
由于操作系统是centos7,那么选择下载的版本为 rabbitmq-server-3.9.8-1.el7.noarch.rpm.
另外需要下载erlang,参考rabbitMQ和rabbitMQ的兼容关系: RabbitMQ Erlang Version Requirements
erlang最低版本为23.2,在此选择了23.3.4.8版本。因为这个版本有支持el7的rpm包可下载。 erlang-rpm
下载的版本为:erlang-23.3.4.8-1.el7.x86_64.rpm
现在将这两个rpm上传到需要安装的服务的/opt/software目录。
首先要安装依赖包:
[root@m161p114 ~]# yum install -y socat

首先要检查host文件,在hosts文件中确保存在hostname对应的ip解析。 在本文中,增加:
192.168.161.114 m161p114
配置管理后台:
[root@m161p114 ~]# rabbitmq-plugins enable rabbitmq_management
Enabling plugins on node rabbit@m161p114:
rabbitmq_management
The following plugins have been configured:
rabbitmq_management
rabbitmq_management_agent
rabbitmq_web_dispatch
Applying plugin configuration to rabbit@m161p114...
The following plugins have been enabled:
rabbitmq_management
rabbitmq_management_agent
rabbitmq_web_dispatch
set 3 plugins.
Offline change; changes will take effect at broker restart.
之后,启动rabbitmq:
[root@m161p114 opt]# service rabbitmq-server start
Redirecting to /bin/systemctl start rabbitmq-server.service
rabbitmq启动完成。
增加用户:
[root@m161p114 opt]# rabbitmqctl add_user root 123456
Adding user "root" ...
Done. Don't forget to grant the user permissions to some virtual hosts! See 'rabbitmqctl help set_permissions' to learn more.
[root@m161p114 opt]# rabbitmqctl set_user_tags root administrator
Setting tags for user "root" to [administrator] ...
[root@m161p114 opt]#
至此,rabbitmq安装完成,可以用新增的用户,访问rabbitMQ:
http://192.168.161.114:15672
这样RabbitMQ就安装完毕,通过service rabbitmq-server 可以对rabbitmq进行启动和关闭。
启动报错:
[root@m161p114 ~]# service rabbitmq-server restart

启动rabbitmq,出现上述错误。 实际上这是端口被占用所致。rabbitmq使用的是5672端口。而这个服务器上由于安装过activeMQ,导致5672端口被占用。

可以看到,5672被activeMQ占用。虽然activeMQ使用的是61616端口,但是amqp服务还是会占用5672端口。 我们只需要关闭activeMQ,然后重启rabbitMQ即可。
增加rabbitMQ 用户的过程中,出现如下错误:
[root@m161p114 etc]# rabbitmqctl add_user root 123456
Error: unable to perform an operation on node 'rabbit@m161p114'. Please see diagnostics information and suggestions below.
Most common reasons for this are:
* Target node is unreachable (e.g. due to hostname resolution, TCP connection or firewall issues)
* CLI tool fails to authenticate with the server (e.g. due to CLI tool's Erlang cookie not matching that of the server)
* Target node is not running
In addition to the diagnostics info below:
* See the CLI, clustering and networking guides on https://rabbitmq.com/documentation.html to learn more
* Consult server logs on node rabbit@m161p114
* If target node is configured to use long node names, don't forget to use --longnames with CLI tools

这需要将rabbitMQ server启动。否则将会出现上述错误。
