Linux之RabbitMQ安装各种问题处理

• 首先在centos7安装Erlang会出现如下问题
  

解决方法为分别输入
		yum install epel-release
		yum install unixODBC unixODBC-devel wxBase wxGTK SDL wxGTK-gl 
来安装依赖环境

• 还可能会出现如下错误 erlang >= 19.3 被 rabbitmq-server-3.7.8-1.el7.noarch
  
  此时需要erlang版本>=19.3，然而默认yum仓库中的版本较低，通过以下途径解决
  输入vim /etc/yum.repos.d/rabbitmq-erlang.repo按i进行编辑
  输入下面一段话

[rabbitmq-erlang]
name=rabbitmq-erlang
baseurl=https://dl.bintray.com/rabbitmq/rpm/erlang/20/el/7
gpgcheck=1
gpgkey=https://dl.bintray.com/rabbitmq/Keys/rabbitmq-release-signing-key.asc
repo_gpgcheck=0
enabled=1

按ESC后:wq保存

然后再输入
yum clean all
yum makecache

• 你可能还会遇到 vim：未找到命令
  通过输入rpm -qa|grep vim 命令发现少东西
  输入yum -y install vim-enhanced来进行安装
  
  安装后
  

• 接着在安装过程又有可能出现如下错误

Transaction check error:

输入yum remove esl-erlang-21.1.1-1.x86_64 esl-erlang-21.1.1-1.x86_64 esl-erlang-21.1.1-1.x86_64 esl-erlang-21.1.1-1.x86_64 esl-erlang-21.1.1-1.x86_64 esl-erlang-21.1.1-1.x86_64 esl-erlang-21.1.1-1.x86_64 esl-erlang-21.1.1-1.x86_64可以解决

• 最后你可能发现没法启动后台管理
  输入rabbitmq-plugins enable/disabled rabbitmq_management
