RabbitMQ Server安装

################################################

1.安装Erlang

sudo yum install erlang

2.安装RabbitMQ Server

需要先导入key

sudo rpm --import http://www.rabbitmq.com/rabbitmq-signing-key-public.asc
可先将内容保存至文本文件，如，rabbitmq-signing-key-public.asc.txt

sudo rpm --import rabbitmq-signing-key-public.asc.txt

3.安装rabbitmq-server-3.4.1-1.noarch.rpm

sudo yum install rabbitmq-server-3.4.1-1.noarch.rpm

4.启动RabbitMQ Server

注册为系统服务

sudo chkconfig rabbitmq-server on

启动RabbitMQ Server

sudo /etc/init.d/rabbitmq-server stop/start/etc

sudo service rabbitmq-server stop/start/etc

5.若启动失败检测端口是否被占用

4369 (epmd), 25672 (Erlang distribution)

5672, 5671 (AMQP 0-9-1 without and with TLS)

15672 (if management plugin is enabled)

61613, 61614 (if STOMP is enabled)

1883, 8883 (if MQTT is enabled)

RabbitMQ Server 配置

##################################################

1.通过环境变量进行配置

可直接在Shell中进行配置

或在rabbitmq-env.conf中配置

2.通过配置文件进行配置

sudo cp /usr/share/doc/rabbitmq-server-3.4.1/rabbitmq.config.example /etc/rabbitmq/rabbitmq.config

sudo vim /etc/rabbitmq/rabbitmq.config

相关文件位置

对于RPM为/etc/rabbitmq/，如/etc/rabbitmq/rabbitmq.config、/etc/rabbitmq/rabbitmq-env.conf

#RabbitMQ 日志、用户、client

#################################################

1.日志

ls -l /var/log/rabbitmq

2.默认virtual host与默认user

virtual host: /

user:guest

passwd:guest

注：默认用户只可在localhost上连至/且有全部权限

3.RabbitMQ Client

python client

pika-0.9.14.tar.gz

tar -xzvf pika-0.9.14.tar.gz

cd pika-0.9.14

sudo python27 setup.py install

JS client

amqp.node
