该文描述了通过SSH连接到devops用户，然后在环境中安装Ansible，创建并配置Ansible目录、inventory文件及主机组。接着，设置了Ansible配置文件，创建角色目录，并在inventory中添加主机变量，最后进行了配置的测试验证。

（1）通过SSH连接到devops用户中

[student@workstation ~]$ ssh devops@workstation

（2）在当前环境中下载ansible

[devops@workstation ~]$ sudo yum install ansible -y
Last metadata expiration check: 0:41:52 ago on Sat 02 Apr 2022 03:35:12 PM GMT.
Package ansible-2.8.0-1.el8ae.noarch is already installed.
Dependencies resolved.
Nothing to do.
Complete!

（3）创建ansible目录，并在此目录创建inventory文件；

[devops@workstation ~]$ mkdir ansible
[devops@workstation ~]$ cd ansible
[devops@workstation ansible]$ vim inventory

（4）在inventory文件中创建相应的主机组

[devops@workstation ansible]$ vim inventory
[dev]
servera
[test]
serverb
[blancers]
serverb
[prod]
server[c:d]
[Webserver:children]
prod

（5）可以通过测试查看创建的主机组

[devops@workstation ansible]$ vim ansible.cfg
[defaults]
inventory = /home/devops/ansible/inventory
roles_path = /home/devops/ansible/roles
host_key_checking = False

[devops@workstation ansible]$ mkdir roles
（7）在配置主机中的文件中添加变量

[devops@workstation ansible]$ vim inventory
[dev]
servera
[test]
serverb
[blancers]
serverb
[prod]
server[c:d]
[Webserver:children]
prod

[all:vars]
ansible_user=root
ansible_password=redhat

（8）可以验证测试配置——测试成功

[devops@workstation ansible]$ ansible-inventory --graph
@all:
|--@Webserver:
| |--@prod:
| | |--serverc
| | |--serverd
|--@blancers:
| |--serverb
|--@dev:
| |--servera
|--@test:
| |--serverb
|--@ungrouped:
[devops@workstation ansible]$ ansible all -m ping
servera | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/libexec/platform-python"
},
"changed": false,
"ping": "pong"
}
serverd | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/libexec/platform-python"
},
"changed": false,
"ping": "pong"
}
serverc | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/libexec/platform-python"
},
"changed": false,
"ping": "pong"
}
serverb | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/libexec/platform-python"
},
"changed": false,
"ping": "pong"
}
