rabbitmq安装

1、从源码安装最新的otperlang17，版本(otp_src_17.1.tar.gz)； ./configure make make install

2、有可能要安装    和simplebean

3、下载rabbitmq源码(rabbitmq-server-3.3.5.tar.gz),

   make TARGET_DIR=/usr/local/rabbitmq SBIN_DIR=/usr/local//rabbitmq/sbin MAN_DIR=/usr/local//rabbitmq/man DOC_INSTALL_DIR=/usr/local/rabbitmq/man

   make install TARGET_DIR=/usr/local/rabbitmq SBIN_DIR=/usr/local/rabbitmq/sbin MAN_DIR=/usr/local/rabbitmq/man DOC_INSTALL_DIR=/usr/local/rabbitmq/man

 

4、配置mq

建立目录：/etc/rabbitmq

 

5、启动

 

/usr/local/rabbitmq/sbin

 

./rabbitmq-server -detached

./rabbitmqctl stop 

 

6、配置web监控

rabbitmq-plugins enable rabbitmq_management

然后重启rabbitmq

 

 

rabbitmq-plugins enable rabbitmq_shovel

rabbitmq-plugins enable rabbitmq_shovel_management

 

7、修改rabbitmq使用的内存

0.4意思是：使用物理内存的40%，达到后不再接收生产者发布消息

./rabbitmqctl set_vm_memory_high_watermark 0.8

 

8、rabbitmq可接收的连接数，取决于进程可打开的句柄数

 

9、大量连接下，erl报错

** WARNING ** Mnesia is overloaded: {dump_log, write_threshold}

解决：

 

2）a configuration file：defines [server component(RabbitMQ core application, Erlang services and RabbitMQ plugins)] settings for permissions, limits and clusters, and also plugin settings.  标准的erlang配置文件，例子：

 

  [
    {mnesia, [{dump_log_write_threshold, 500000}]},
    {rabbit, [{tcp_listeners, [5673]}]}
  ].

     export RABBITMQ_SERVER_ERL_ARGS="+K true +A30 +P 2048576 -kernel inet_default_connect_options [{nodelay,true}]"
