解决RabbitMQ service is already present

C:\Users\Administrator>rabbitmq-service install

RabbitMQ service is already present - only updating service parameters C:\Program Files\erl5.10.3\erts-5.10.3\bin\erlsrv: Warning, could not set correct interactive mode. Error: 句柄无效。 C:\Program Files\erl5.10.3\erts-5.10.3\bin\erlsrv: Warning, could not set correct service description (comment)Error: 句柄无效。 C:\Users\Administrator>rabbitmq-service stop C:\Program Files\erl5.10.3\erts-5.10.3\bin\erlsrv: Failed to stop service RabbitMQ. Error: 句柄无效。  

当出现如上问题时，解决办法是卸载erlang并且去注册表里HKLM/SOFTWARE/Ericsson/Erlang/ErlSrv下的项清掉，然后重新已管理员身份安装erlang

重装完成后若RabbitMQ service未安装则通过：rabbitmq-service install  安装service；rabbitmq-service start   启动service
