Question

我安装了erlang（erlang-20.3.7-1.el7.centos.x86_64.rpm），已安装的rabbimq（rabbitmq-server-3.7.6）。当我检查节点状态时，rabbitmqctl得到了暗恋消息。我丢失了什么吗？许多美貌！

我刚刚安装了rabbitmq-server v3.7.6，如果您正在运行基于debian的发行版，请确保将esl-erlang和erlang*软件包固定到20.3.x（{{3 }}）。另外，请确保/var/lib/rabbitmq目录属于rabbitmq用户和组。如果不是，请使用chown -R rabbitmq:rabbitmq /var/lib/rabbitmq进行修复。最后，只需安装这些软件包之一，esl-erlang或erlang。

我看到您键入了erlang-20.3.7-1.el7.centos.x86_64.rpm，但是v20.3.x分支的最新版本是v20.3.6。请再次检查...

阅读与erlang / otp see here for more detail的Rabbitmq兼容性。我已经使用上述配置进行了测试，并且在输入sudo rabbitmq-ctl status后可以正常使用。

如果成功，您可能会看到以下结果。

因为安装了错误的erlang版本，所以您需要最新的erlang版本20.3，因为21版本仅适用于Rabbitmq版本3.7.6 beta。

要安装rabbitmq及其依赖项

sudo apt install rabbitmq-server erlang-base=1:20.3-1 erlang-syntax-tools=1:20.3-1 erlang-asn1=1:20.3-1 erlang-crypto=1:20.3-1 erlang-mnesia=1:20.3-1 erlang-runtime-tools=1:20.3-1 erlang-public-key=1:20.3-1 erlang-ssl=1:20.3-1 erlang-diameter=1:20.3-1 erlang-inets=1:20.3-1 erlang-xmerl=1:20.3-1 erlang-edoc=1:20.3-1 erlang-eldap=1:20.3-1 erlang-erl-docgen=1:20.3-1 erlang-eunit=1:20.3-1 erlang-ic=1:20.3-1 erlang-inviso=1:20.3-1 erlang-odbc=1:20.3-1 erlang-snmp=1:20.3-1 erlang-os-mon=1:20.3-1 erlang-parsetools=1:20.3-1 erlang-percept=1:20.3-1 erlang-ssh=1:20.3-1 erlang-tools=1:20.3-1 erlang-nox=1:20.3-1

无法部署最新的rabbitmq？
