Ansible is a lightweight batch configuration management tool for agentless, because of the relatively late (13) development based on ansible less relevant documents, so here are some small experiments, combined with the existing data and source code, explore the Ansible two times development.The contents of the essay are divided into three parts.

Puppet-developed based on Ruby and adopts a C/S architecture. It is highly scalable and SSL-based, and remote command execution is relatively weak.SaltStack-developed based on Python and adopts the C/S architecture. It is more lightweight than puppet. The configuration syntax uses YMAL to make the configuration script simpler.
Ansible is an automated operations tools, based on the development of Python, the collection of many operations tools (puppet, Cfengine, Chef, func, fabric) The advantages of the implementation of batch system configuration, batch program deployment, batch Run command and other functions.Ansible is a module-based capability that does not have the ability to deploy in batches. The real batch deployment is the module that

Inventory fileAnsible can operate concurrently with multiple hosts belonging to one group, the relationship between the combined hosts is configured through the inventory file, the default file path is/etc/ansible/hostsIn addition to the default files, you can use multiple inventory files at the same time, or you can pull inventory configuration information from a dynamic source or from the cloud--------------------------------------------------------

I. Ansible Introduction
Ansbile is a powerful python-based batchcompute Command Execution tool. It has powerful functions in managing a large number of clusters. It is small in size and has little dependencies, and has a general trend.
II. Install
The ansible Binary Package is provided in RHEL6. When using CentOS6, you may need to add an epel source.

Background information:There are a lot of facts in ansible, but not enough in many cases.For example, Ansible has no ansible_private_ipv4_address such a facts, which is used to save a private network IP address.And we just need such a facts, because we have a lot of server's default network card is not eth0, some bond0,eth1,em0,em1, and the public network IP address and private network IP address also does
The ansible only needs to be run on a common server and does not require the client to be installed on the managed server. Because it is SSH-based, the Linux server cannot be separated from SSH, so ansible does not need to add additional support for the configuration work. You can use ansible from the command line, the server running
In the field of automation operations, in addition to Saltstack, there are ansible this batch installation Deployment tool, in writing the specific content first, first of all I used two tools after the sentiment.Saltstack is the C/s framework, in order to install software in the client, and start the service to manage, ansible is connected via SSH to the client, that is, the key must be passed to the clien
