RabbitMQ 已经经历了10 来个春夏秋冬，全球超过35000生产部署RabbitMQ，RabbitMQ是最受欢迎的开源消息队列，
正如官网的介绍：

RabbitMQ 安装
访问RabbitMQ官网 下载对应系统版本，这里我们下载Debian Ubuntu 对应的版本。

如上rabbitmq-server依赖于erlang-nox，下面安装输入：sudo apt-get install erlang-nox
but 依然报错
1 | alex@ubuntu:~/work$ sudo apt-get install erlang-nox |
根据提示，执行 apt-get -f install
中途提示：Do you want to continue? [Y/n] 输入 Y
1 | alex@ubuntu:~/work$ sudo apt-get -f install |
再次输入：sudo dpkg -i rabbitmq-server_3.6.10-1_all.deb
1 | alex@ubuntu:~/work$ sudo dpkg -i rabbitmq-server_3.6.10-1_all.deb |
显然如上结果，表示 rabbitmq-server 安装完成，启动rabbitmq-server 服务
1 | // 启动 rabbitmq-server |
- 若通过终端安装程序sudo apt-get install xxx时出错：

3sudo apt-get install erlang-nox
E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it
通过如下强制解锁,命令
1 | $ sudo rm /var/lib/dpkg/lock |
再次输入安装命令，可能会会提示 “E: dpkg 被中断，您必须手工运行 sudo dpkg –configure -a 解决此问题”
按照提示执行：sudo dpkg –configure -a
RabbitMQ 管理插件 management plugin
RabbitMQ 默认已经集成了management plugin，通过命令enable即可
1 | $ cd /usr/lib/rabbitmq/bin/ |
当显示如上信息，打开浏览器访问：http://localhost:15672
输入默认用户名/密码：guest/guest 登陆Web管理页：
guest用户只能从localhost地址登录，如果要配置远程登录，必须创建用户
- 通过Web管理页面添加用户并设置权限，点击用户进入授权页面，默认直接点击”set permission”即可
- 通过命令添加用户,并分配权限：

Creating user "admin"
$ sudo rabbitmqctl set_user_tags admin administrator
Setting tags for user "admin" to [administrator]
$ sudo rabbitmqctl set_permissions -p / admin ".*" ".*" ".*"
Setting permissions for user "admin" in vhost "/"
设置完成后，RabbitMQ就可以远程通过 http://rabbitmq_ip:15672 访问了。
