安装RabbitMQ(一)

 

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版本链接查询地址：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，可是rabbitmq服务已经启动成功

注意:出现这种状况，运行以下命令
[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

 

若是启动失败以下处理：

[root@besttone2 rabbitmq]# rabbitmq-server restart

解决措施：

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

查看rabbitmq安装在那里：

1. whereis rabbitmq

2. whereis erlang

 

查询yum安装的相关包：

yum list | grep erlang

卸载 MQ：

rpm -q -a | grep MQSeries

卸载erlang相关的包：

yum remove erlang-asn1.x86_64  

使用rabbitctl添加用户

第1、添加mq用户并设置密码

root@live-mq-01:~ # rabbitmqctl add_user mq 123456

1	root@live-mq-01:~ # rabbitmqctl add_user mq 123456

第2、添加mq用户为administrator角色

root@live-mq-01:~ # rabbitmqctl set_user_tags mq administrator

1	root@live-mq-01:~ # rabbitmqctl set_user_tags mq administrator

第3、设置mq用户的权限，指定容许访问的vhost以及write/read

root@live-mq-01:~ # rabbitmqctl set_permissions -p "/" mq ".*" ".*" ".*"Setting permissions for user "live" in vhost "/" ......done.

1 2 3

root@live-mq-01:~ # rabbitmqctl set_permissions -p "/" mq ".*" ".*" ".*" Setting permissions for user "live" in vhost "/" ... ...done.

第4、查看vhost（/）容许哪些用户访问

root@live-mq-01:~ # rabbitmqctl list_permissions -p /Listing permissions in vhost "/" ...mq .* .* .*...done.

1 2 3 4

root@live-mq-01:~ # rabbitmqctl list_permissions -p / Listing permissions in vhost "/" ... mq .* .* .* ...done.

第5、配置容许远程访问的用户，rabbitmq的guest用户默认不容许远程主机访问。

root@live-mq-01:~ # cat /etc/rabbitmq/rabbitmq.config [ {rabbit, [{tcp_listeners, [5672]}, {loopback_users, ["mq"]}]}].

1 2 3 4

root@live-mq-01:~ # cat /etc/rabbitmq/rabbitmq.config [                                                                                                                                   {rabbit, [{tcp_listeners, [5672]}, {loopback_users, ["mq"]}]} ].
