ActiveMQ Part 1: Basic Installation configuration (Windows version)

1. Install the start-up service

A) First download and install the latest JDK (this article uses: Jdk-8u66-windows-x64.exe)

B) Download the latest installation package from the official website (this download version is: http://activemq.apache.org/activemq-5143-release.html)

C) after unpacking the installation package, locate it in the Decompression directory: \bin\win64\activemq.bat (32-bit machine executes the corresponding Activemq.bat file in the Win32 directory)

Running Activemq.bat as Administrator, the ACTIVEMQ service has been successfully launched with the following complete interface;

Open a browser to access ActiveMQ WEB Management console: http://localhost:8161/admin/(default login username password: admin/admin)

2. Basic Configuration

A) Enable Debug logging (easy to install configuration process to find more detailed questions): Open \conf\log4j.properties, add: Log4j.logger.org.apache.activemq=debug in File, Restart the console program to take effect;

This will output the DEBUG type log in the log.

B) WEB Console permissions configuration: Open the \conf\jetty-realm.properties file, you can modify the role, user name, password, or add the user, after the change to restart the console to take effect;

1 # defines users that can access the Web (console, demo, etc.) 2 [, rolename ... ]3 admin:admin, admin4 user:user, user

According to management needs, self-configuration, this article is configured to follow the following use.

1 # defines users that can access the Web (console, demo, etc.) 2 [, rolename ... ]3 webadmin:web.admin, admin4 webuser1:user.1, user5 WEBUSER2:USER.2, user

C) Configure the Boot protocol: default all ActiveMQ supported protocols will be started, this article mainly launches the MQTT protocol, open file: \conf\activemq.xml;

Locate the following configuration and remove or comment out the other protocols above, leaving only the MQTT protocol;

D) MQTT protocol settings: ActiveMQ initiates the monitoring service based on the protocol configured above, and can enrich the functionality of the MQTT protocol by adding the following configuration;

maximumconnections=1000&wireformat.maxframesize=104857600: to prevent DOS attacks, concurrent connections and maximum transmission capacity limits (Maximum capacity: 256MB);

transport.defaultkeepalive=60000: Configure the default heartbeat of the server, the default is: If the client's heartbeat time is 10s, the service side of the detection time for the connection is: 10*1.5=15s;

Allowlinkstealing=false: If there are two or more connections using the same cilentid, it is considered hotlinking; the server forces the old connection to be closed (the following information can be seen from the log)

WARN | stealing link for clientId PUBSameID-001 from Connection

transport.activemqsubscriptionprefetch=100: If the processing power of the Subscriber is strong, the higher the value, the better, that is, the server will be pre-fetching how much message to the subscriber;

This setting needs to evaluate the minimum processing power of the subscriber and configure it according to the server performance;

The following 4 configurations are the best configurations for many cases:

wireformat.maxinactivityduration=30000: If the server does not receive a message from a connection within 30s, the connection is automatically disconnected;

wireformat.maxinactivitydurationinitaldelay=10000: Specifies the inactive link monitor (InactivityMonitor)" 在多长时间后启动，在需要并发创建许多连接场景非常有效；

transport.useinactivitymonitor=true: enable "Inactive link Monitor", if set to False, the server does not monitor "inactive connection";

transport.usekeepalive=true: If set to False, the server is not forced to close the connection when the data is confiscated outside the heartbeat time;

OK, common configuration to this end, start the AMQ service to start using.
