Mcollective architecture 2-mcollective + MQ architecture deployment

Zero-basic learning puppet automated configuration management documents

1 mcollective Introduction

Mcollective is a framework for server orchestration and parallel execution systems. First, mcollective is a system management solution that provides programmable control over Server clusters. At this point, it features similar functions: func, fabric and Capistrano.

Second, the design of mcollective breaks the path of a central storage-based system and a tool like SSH, and is no longer obsessed with the SSH for loop. It uses modern tools such as publish subscribe middleware and a modern concept of discovering network resources in real time through the target data (meta data) instead of the Host Name (hostnames. Provides a scalable and rapid parallel execution environment.

The mcollective tool is a command line interface, but it can communicate with thousands of application instances, and the transmission speed is amazing. Regardless of the location of the deployed instance, the communication can be transmitted at line speed, using a push information system similar to multi-channel transmission. The mcollective tool does not have a visual user interface. You can only retrieve the instances to be applied. Puppet dashboard provides this function.

2.1.3 configure rabbitmq

2.1.3.1 load the amqp_client and rabbit_stomp plug-ins

  TCP 0 0: 5672: * Listen 1906/beam. SMP

2.1.3.3 Delete the default account guest, create an account "mcollective" for mcollective, set the password to "secret", and set permissions.

[[Email protected] RPMs] # rabbitmqctl delete_user guestdeleting user "guest "...... done. [[email protected] RPMs] # rabbitmqctl add_user mcollective secretcreating user "mcollective "...... done.

[[email protected] sbin] # rabbitmqctl list_users # view the listing users of the listener... mcollective []... done.

Note:Rabbitmq has a default Guest Account, which has all permissions on message queues by default. We recommend that you delete this account for security reasons.
