192.168.245.130 worker0
192.168.245.131 worker1
192.168.245.132 worker2
192.168.245.133 worker3

erlang-debuginfo-25.0.3-1.el8.x86_64.rpm
erlang-debugsource-25.0.3-1.el8.x86_64.rpm
rabbitmq-server-3.10.6-1.el8.noarch.rpm

rpm -ivh erlang-25.0.3-1.el8.x86_64.rpm
rpm -ivh erlang-debuginfo-25.0.3-1.el8.x86_64.rpm
rpm -ivh erlang-debugsource-25.0.3-1.el8.x86_64.rpm
rpm -ivh rabbitmq-server-3.10.6-1.el8.noarch.rpm

解决错误提示

[/usr/lib/tmpfiles.d/rabbitmq-server.conf:1] Line references path below legacy directory /var/run/, updating /var/run/rabbitmq → /run/rabbitmq; please update the tmpfiles.d/ drop-in file accordingly.

解决办法如下：

vim /usr/lib/tmpfiles.d/rabbitmq-server.conf
将
D /var/run/rabbitmq 0755 rabbitmq rabbitmq -
改为
D /run/rabbitmq 0755 rabbitmq rabbitmq -
