参数优化
创建如下配置文件位于：/etc/rabbitmq目录下（这个目录需要自己创建） 环境变量配置文件：rabbitmq-env.conf 配置信息配置文件：rabbitmq.config（可以不创建和配置，修改） rabbitmq-env.conf配置文件： ---------------------------------------关键参数配置------------------------------------------- RABBITMQ_NODE_IP_ADDRESS=本机IP地址 RABBITMQ_NODE_PORT=5672 RABBITMQ_LOG_BASE=/var/lib/rabbitmq/log RABBITMQ_MNESIA_BASE=/var/lib/rabbitmq/mnesia 配置参考参数如下： RABBITMQ_NODENAME=FZTEC-240088 节点名称 RABBITMQ_NODE_IP_ADDRESS=127.0.0.1 监听IP RABBITMQ_NODE_PORT=5672 监听端口 RABBITMQ_LOG_BASE=/data/rabbitmq/log 日志目录 RABBITMQ_PLUGINS_DIR=/data/rabbitmq/plugins 插件目录 RABBITMQ_MNESIA_BASE=/data/rabbitmq/mnesia 后端存储目录 更详细的配置参见： http://www.rabbitmq.com/configure.html#configuration-file 配置文件信息修改： /usr/lib/rabbitmq/lib/rabbitmq_server-3.6.4/ebin/rabbit.app和rabbitmq.config配置文件配置任意一个即可，我们进行配置如下： vim /usr/lib/rabbitmq/lib/rabbitmq_server-3.6.4/ebin/rabbit.app -------------------------------------关键参数配置---------------------------------------- tcp_listerners 设置rabbimq的监听端口，默认为[5672]。 disk_free_limit 磁盘低水位线，若磁盘容量低于指定值则停止接收数据，默认值为{mem_relative, 1.0},即与内存相关联1：1，也可定制为多少byte. vm_memory_high_watermark，设置内存低水位线，若低于该水位线，则开启流控机制，默认值是0.4，即内存总量的40%。 hipe_compile 将部分rabbimq代码用High Performance Erlang compiler编译，可提升性能，该参数是实验性，若出现erlang vm segfaults，应关掉。 force_fine_statistics， 该参数属于rabbimq_management，若为true则进行精细化的统计，但会影响性能
