the Etag is primarily useful when downloading breakpoints. The Expires/cache-control Header is the control of whether the browser caches data directly from the browser or re-sends requests to the server to fetch data . Just Cache-control more than Expires can control, and cache-control will rewrite Expires 's rules. Last-modified/if-modified-since and etag/if-none-match are when the browser sends a request to the server to determine if the file has been modified , if not modified, send only o

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

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

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

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.

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.
