IntroductionPlaybooks is the language of Ansible management configuration, deployment applications, and orchestration, and you can use playbooks to describe the policies you want to perform on the remote host or the set of steps that you perform.Similar to a set of task sets, defining information such as projects, organizational structures, profiles, and so on, the task is to organize the things you want to do in one step and the whole playbookOffi

Do operation and maintenance of the classmate many have used Ansible bar, open Source Batch deployment tool ranked top three: puppet, Saltstack, Ansible.Ansible is characterized by the absence of agents, the use of SSH protocol to communicate, lightweight, written in Python, can write playbook, can also do some ad-hoc batch command execution operations.The recent execution of the ansible command on two

ObjectiveI've been looking at ansible. A configuration management tool, compared to Big Brother Puppet, is simpler to use and can execute commands in bulk, comparing Saltstack written in Python, without having to install a client (based on Paramiko). Also more flexible, especially our existing login method, through the Springboard Machine encryption key, converted into ansible cost is very low, ready to lea

How to Use the ansible callback plug-in to parse the execution results, ansiblecallback Recently I was writing a Batch Inspection tool to push the script to each machine using ansible for execution, and then return the execution result in json format. As follows: # Ansible node2-m script-a/root/python/health_check.py node2 | SUCCESS => { "changed": true,

First, the demand Online machine more, before using Excel statistics once, with ansible batch execution script, and then according to the display information, hand input to Excel, efficiency can imagine. Other departments to view the host information, not the first time to provide, so, just think, can be displayed in a static page, placed in the Apache Htdoc directory. After finding a ansible-cmd

What is expectExpect is a relatively simple and easy-to-use script programming language based on TCL, used for automatic and interactive task programs to communicate, without manual intervention, such as SSH FTP, these programs normally need to manually interact with them, The use of expect can be used to simulate the process of manual interaction, to achieve automatic and remote program interaction, so as to reach the purpose of automationExpect proc

SCP is very powerful, but requires manual input of password, of course, you can save the public key in the remote host's ~/.ssh directory, and then do not enter password, but this needs to be configured.Use Sshpass may enter password in command, but need to be installed with "sudo apt-get install Sshpass"If you do not want to use the above two methods, you can write scripts with expect can help us to automatically interactAlthough Python also offers p

In shell development, when we connect to FTP or passwd or sudo, we need to enter the password manually. This is obviously inappropriate for automation. And expect's strong interaction model solves this problem. I am involved in this work, the individual is also simple to understand, solve practical problems, as a learning record.One: Installation "Reference address: https://www.cnblogs.com/lixigang/articles/4849527.html"Expect needs the support of TCL

Preface: The last article said cobbler, this article is expect. Before distributing the file, we use the For loop to read the IP in turn. Of course you have to get through the SSH channel first. Although it is said that expect do not have to do anything in advance to prepare, just write two scripts. But personally, I don't think SSH is secure. Because you have to write your account into a file before you us

Some of the operation under Linux, sometimes need to do some interaction with the machine, such as the user to switch account password, transfer files to enter the account password login remote machine, etc., but sometimes these actions need to be done in the shell script, At this point, you can use expect to automate the interaction, thus avoiding the need for manual intervention to interrupt the execution of the script.Core command of

Expect is used to provide automatic interaction with the tool. For example, if you want to ssh into the server, each time you enter the password you feel trouble, then you can use expect to do automatic interaction, so that you do not have to enter the password every time.First look at the example:# !/usr/bin/expect#set Timeout #设置超时时间Spawn ssh [email protected]"

From:http://www.nginx.cn/1934.htmlWhere the shell script needs to interact with the here document is the implementation, but some commands require the user to manually go on the interaction such as passwd, SCPIt is very painful to eliminate user interaction for automatic deployment, expect can solve this kind of problem very well.The core of expect is spawn expect
