ansible requirements

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

Automated operations Tools: ansible Application scenario for multi-process call Ansible API: Application System Check An application system may have a cluster of 20-50 servers, and a preliminary system-level check can be checked with a unified playbook, such as (Df-h command). But deep into the application layer, there are some personalized applications, such as 2 HTTP servers, 20 middleware

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

The goal of this tool is to automate app deployment, automate configuration management, automate continuous delivery, and automate (AWS) cloud service management. All these goals are essen

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.

First, Introduction Ansible is a configuration management and application Deployment tool that functions like the current Industry configuration management tool Chef,puppet,saltstack. Ansible is developed through the Python language. The Ansible platform, created by Michael DeHaan, is also the author of a well-known software cobbler and Func. The first version

I. Preparation of the first order Ansible installation is complete, below learn how to use ansible.Just like learning a programming language, first write a Hello World sample program. 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

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

Ansible through the way of the module to complete some remote management work. 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. IP and host name are: IP host name note 192.168.128.10 Ansible-manager Management host 192.168.128.11 Ansible-demo1 managed host 1 192.168.128.12

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

Ansible Problems Developed based on paramiko. What is this paramiko? It is a python-Only SSH protocol library. Therefore, fabric and ansible do not need to install client/agents on a remote host because they communicate with remote hosts Based on SSH. The inventory file is used to define the host to be managed. The default location is/etc/ansible/hosts.

Ansible automated O M tool learning Manual 1. Introduction to ansibleCommon automated O M tools 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.
