We also write a ansible "Hello World": Ansible 192.168.128.83-m Ping This command means ping 192.168.128.83 through the admin hostThe "-M ping" in the command indicates that the pi

Ansible supports Windows from the 1.7+ version, with the actual measurement of Windows 7 SP1 and Windows Server R2 and above, the system is simply configured to communicate with Ansible normally. However, the following points need to be met:1, the management machine must be a Linux system, and the original Python winrm module2. The underlying communication is based on PowerShell and the version is 3.0+,mana

Before we start, let's think of a scenario where your company has hundreds of servers, and when the leader asks to add a timed task to all the servers, or execute a command, you might say that you can use Xshell to connect or write a shell script. But if you have experienced something like this, you can certainly experience the pain, because so many servers you use Xshell to connect the workload will become particularly large, but if you choose to write a script, it will be particularly troubles

Ansible: a configuration management and IT automation tool Today I will talk about ansible, a powerful configuration management solution compiled by Python. Although there are already many configuration management solutions available on the market, they have their own advantages and disadvantages, and ansible is characterized by its conciseness. What distinguish

Ansible is a free, open-source configuration and automation tool developed for Unix-like systems. It is written in Python and is similar to Chef and Puppet. but there is a difference and advantage that we do not need to install any client in the node. It uses SSH to communicate with nodes. In this article, we will install and configure Ansible on CentOS7 and try to manage the two nodes.

Create ansible and manage container nodes based on DockerScenario: When learning conditions are limited, you can complete Docker and ansible learning with a single VMFIX: Create a custom image and build multiple ansible containers first.Of course, this method is suitable for other similar scenarios.VMS Environment: Os:centos7docker version 1.12.3, build

YAML syntaxThis article is from: http://www.ansible.com.cn/docs/YAMLSyntax.htmlThis page provides a basic overview of the correct YAML syntax, which is used to describe a playbooks (our Configuration management language).We use YAML because it is like XML or JSON as a data format that facilitates people's reading and writing. In addition, there are libraries that use YAML in most languages.You may want to read how playbooks is used in practice.Basic Y

I. Basic Knowledge: 1. Introduction Ansible is developed based on Python and combines the advantages of many O M tools to implement features such as batch system configuration, batch program deployment, and batch run commands. Ansible works based on modules and does not support batch deployment.The ansible module is actually deployed in batches, and

You can view all modules through ansible-doc-l, you can use Ansible-doc-s module to view the parameters of a module, or you can use Ansible-doc Help module to view more detailed information about the module. The default module location is/us

First, host planning Create 4 virtual machines as a demo ansible environment, install the operating system as CentOS 7.4. 1 of them as management host, the other 3 as the managed host.
