First, installation

1. Installing Erlang1) System compilation Environment (Linux/unix environment is used here)① Installation Environment

after installing Erlang, start loading rabbitmq-server, the main reference Official document:http://www.rabbitmq.com/build-server.html ; ② Installing Simplejson (if you need to install a Python version )

A newer version of Python needs to be installed. Easy to install .

Second, the configuration

Main references official documents:http://www.rabbitmq.com/configure.html

In general, the default configuration for RABBITMQ is sufficient. If you want a special setting, there are two ways:

• One is the environment variable configuration file rabbitmq-env.conf;
• A configuration file that is configuration information rabbitmq.config;

Note that these two files are not by default and must be created yourself if necessary.

Rabbitmq-env.conf
The location of this file is deterministic and immutable, located in:/etc/rabbitmq directory (this directory needs to be created by itself).

• The contents of the file include some of the environment variables of RABBITMQ, commonly used are:
• #RABBITMQ_NODE_PORT =//Port number
• #HOSTNAME =
• Rabbitmq_nodename=mq
• rabbitmq_config_file=//path of the configuration file
• Rabbitmq_mnesia_base=/rabbitmq/data//path of the MNESIA database to be used
• Rabbitmq_log_base=/rabbitmq/log//log's Path
• Rabbitmq_plugins_dir=/rabbitmq/plugins//plug-in Path

For a specific list, see:http://www.rabbitmq.com/configure.html#define-environment-variables

Rabbitmq.config
This is a standard Erlang configuration file. It must conform to the standards of the Erlang profile.
It has both a default directory and can be configured in the rabbitmq-env.conf file.

The contents of the file are described in:http://www.rabbitmq.com/configure.html#config-items

third, monitoring

Main references official documents:http://www.rabbitmq.com/management.html

RABBITMQ provides a web-based monitoring page system that is invoked in a plugin manner.

First, configure the location of the plugins directory in rabbitmq-env.conf: Rabbitmq_config_file

Download the plugin required for the monitoring page to the plugins directory, which includes the following plugin:

• Mochiweb
• Webmachine
• Rabbitmq_mochiweb
• Amqp_client
• Rabbitmq_management_agent
• Rabbitmq_management

Download path is located at:http://www.rabbitmq.com/plugins.html#rabbitmq_management

Restart the RABBITMQ and enter the http://server-name:55672/mgmt/to access the monitoring page. The default user name and password are: Guest and guest.
