Python environment and into the ansible
Python3.6 into the virtual environment
#su - deploy
#source .py3-a2.5-env/bin/activate
Load ansible 2.5 version
#source .py3-a2.5-env/ansible/hacking/env-setup -q

#ansible-playbook --version
Write playbooks framework
Create a new directory and multiple directories
#mkdir test_playbooks
#cd test_playbooks/
#mkdir inventory roles
Into inventory, create testenv file,
# Cd inventory
#vi testenv
Add the target host service address
[testservers]
test.example.com
[testservers:vars]
server_name=test.example.com
user=root
output=/root/test.txt
Return to the parent directory
#cd ../
Into the roles directory, create a subdirectory
#cd roles
#mkdir -p testbox/tasks
Enter the subdirectory, create main.yml files, playbooks as the main configuration file
#cd testbox/tasks/
#vi main.yml
Add test tasks, save and exit
- name: Print server name and user to remote testbox
shell: "echo 'Currently {{ user }} is logining {{ server_name }}' > {{ output }}"Return to the test_playbooks directory
#cd ../../..
Playbooks create a task entry file, save and exit
#vi deploy.yml
- hosts: "testservers" # 对应testenv文件下主标签，用定义调用标签下目标主机
gather_facts: true # 获取目标主机信息
remote_user: root # 告诉ansible在目标主机下，使用root账户权限，进行所有系统的文件操作
roles: # 进入roles下testbox任务目录，进行接下来的任务执行
- testboxTree in print playbooks directory
#tree .
Configure key authentication ansible host and directory host
Returns the root user
#su - root
Edit hosts
#vi /etc/hosts
Add dns records test.example.com
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.96.151 test.example.com
