安裝RabbitMQ(一)

安裝Erlang 

安裝erlang環境

用yum安裝erlang

yum install erlang

執行上面語句時報錯說找不到包，那得先安裝EPEL庫
yum install epel-release
再執行
yum install erlang
--------------------- 

下載安裝rabbitmq

mq版本連線查詢地址：http://www.rabbitmq.com/releases/rabbitmq-server/v3.1.5/

下載安裝rabbitmq
[
 
[email protected] local]#wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.1.5/rabbitmq-server-3.1.5-1.noarch.rpm
[[email protected] local]#yum -y install rabbitmq-server-3.1.5-1.noarch.rpm

[[email protected] local]#rabbitmq-server start  //啟動
  或者這樣啟動：rabbitmq-server -detached
Warning: PID file not written; -detached was passed.
我這裡是提示這個，但是rabbitmq服務已經啟動成功

注意:出現這種情況，執行如下命令
[
 
[email protected] local]#yum remove esl-erlang-20.0-1.x86_64 esl-erlang-20.0-1.x86_64 esl-erlang-20.0-1.x86_64 esl-erlang-20.0-1.x86_64 esl-erlang-20.0-1.x86_64 esl-erlang-20.0-1.x86_64 esl-erlang-20.0-1.x86_64 esl-erlang-20.0-1.x86_64

啟動成功

如果啟動失敗如下處理：

[[email protected] rabbitmq]# rabbitmq-server restart
