Asible is a very good tool in the operation of tools, I personally prefer, can be flexibly configured according to the needs of yml files to achieve different business needs, because do not need to install the client, the start is very easy, In some cases you might want to write ansible as a library component of Python into your own script, and today's script script will show how

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

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

Managing remote servers in bulk using AnsibleBackground local need to manage the remote batch of servers, mainly perform the following tasks: 1) Copy Local files to all remote servers; 2) need to execute commands on remote server; Remote server path is not exactly the same. General access to the variable path defined in the environment variable; For example, define $app_path=/opt/app/bin final selection ansible in. BASHRC, and use this automated OPS

Objective:Sometimes we need to define a host group when automating and batching the operations master. For example, Saltstack group, and Salt-n parameters, in Ansible under the self-fix ansible of the host group. Some trouble, you know, since you choose to use Saltstack, ansible this kind of cluster operation tool, if

Ansible automatic operation and Maintenance tool configuration Ngnix front end to back-end real machine, and set keepalived high availability, on the back end a real host configuration httpd,mysql,php-fpm; set memcached cache server on this real host (Because of my Computer configuration problem, can not open so many virtual machines, so simply build a bit)IP configuration:Directory1 (MASTER):eno16777736:17

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

the list's way table to identify the individual hosts, such as: [webserver]www[01:50].test.org ansible_ssh_user=root ansible_ssh_pass=123456 #支持01到50，用户为root，密码为123456[dbbservers]db-[a:f].test.org #支持匹配a b c ... fThere are several important concepts in inventory. 1), host variables Host variables can be added when the host is defined for use in subsequent playbook, such as [webserver]www1.test.com http_port=80 maxRequestsChild=808www2.test.com http_port=8080 max

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.
