安装RabbitMQ(一)

安装Erlang

安装erlang环境

用yum安装erlang

yum install erlang

执行上面语句时报错说找不到包，那得先安装EPEL库
yum install epel-release
再执行
yum install erlang
---------------------

下载安装rabbitmq

mq版本连接查询地址：http://www.rabbitmq.com/releases/rabbitmq-server/v3.1.5/

下载安装rabbitmq
[root@bogon local]#wget http://www.rabbitmq.com/releases/rabbitmq-server/v3.1.5/rabbitmq-server-3.1.5-1.noarch.rpm
[root@bogon local]#yum -y install rabbitmq-server-3.1.5-1.noarch.rpm

[root@bogon local]#rabbitmq-server start  //启动
  或者这样启动：rabbitmq-server -detached
Warning: PID file not written; -detached was passed.
我这里是提示这个，但是rabbitmq服务已经启动成功

Transaction check error:

注意:出现这种情况，运行如下命令
[root@bogon 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

启动成功

如果启动失败如下处理：

[root@besttone2 rabbitmq]# rabbitmq-server restart

解决措施：
/var/log/rabbitmq/ 这个目录下的两个日志文件的用户和组设定成rabbitmq

chmod -R rabbitmq:rabbitmq /var/log/rabbitmq/
