RabbitMQ 环境变量

RabbitMQ 的环境变量都是以"RABBITMQ_"开头的，可以在Shell 环境中设置，也可以在配置文件中定义。默认的配置文件如下：

##
/etc/rabbitmq/rabbitmq-env.conf

定义配置文件：

/va/lib/rabbitmq/ 的目录不要删除，因为systemd 的工作目录还是： WorkingDirectory=/var/lib/rabbitmq/

$sudo cat rabbitmq-env.conf 
NODENAME=rabbit@bigdata-02
RABBITMQ_MNESIA_BASE=/opt/data/rabbitmq/data/
RABBITMQ_LOG_BASE=/opt/data/rabbitmq/log/## 
chown -R rabbitmq:rabbitmq /opt/data/rabbitmq/

检测：

$sudo systemctl status rabbitmq-server.service
