在使用rpm方式安装rabbitmq时，执行yum install rabbitmq-server-3.7.18-1.el7.noarch.rpm出现以下问题：

yum install rabbitmq-server-3.7.18-1.el7.noarch.rpm 
    Loaded plugins: fastestmirror
    Examining rabbitmq-server-3.7.18-1.el7.noarch.rpm: rabbitmq-server-3.7.18-1.el7.noarch

                   erlang = R16B-03.18.el7
     You could try using --skip-broken to work around the problem
     You could try running: rpm -Va --nofiles --nodigest

通过erl查看，发现已经安装了21.0的erl，这时需要重新安装最新的erlang

**1.手动配置erlang的repo源**  
vi /etc/yum.repos.d/rabbitmq-erlang.repo  
在文件中加入以下内容：

# In /etc/yum.repos.d/rabbitmq-erlang.repo
    [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

**2.清理rpm文件缓存**  
yum clean all  
yum makecache

**3.查看已有的源文件**  
yum list |grep erlang 此时发现有一个21.3的文件可以用，我们就安装这个文件

yum install erlang.x86\_64  
完成后继续执行yum install rabbitmq-server-3.7.18-1.el7.noarch.rpm提示成功
