安装ansible-2.4.6的软件包

wget https://releases.ansible.com/ansible/rpm/release/epel-7-x86_64/ansible-2.4.6.0-1.el7.ans.noarch.rpm
 
# yum本地安装
yum localinstall ansible-2.4.6.0-1.el7.ans.noarch.rpm -y
 
# 验证安装(ok)
[root@localhost local]# ansible --version
ansible 2.4.6.0
  config file = /etc/ansible/ansible.cfg
  configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']
  ansible python module location = /usr/lib/python2.7/site-packages/ansible
  executable location = /usr/bin/ansible
  python version = 2.7.5 (default, Nov 16 2020, 22:23:17) [GCC 4.8.5 20150623 (Red Hat 4.8.5-44)]
 
# 验证功能(ok)
[root@localhost local]# ansible 127.0.0.1 -m ping
 [WARNING]: provided hosts list is empty, only localhost is available. Note that the implicit
localhost does not match 'all'
 
127.0.0.1 | SUCCESS => {
    "changed": false, 
    "failed": false, 
    "ping": "pong"
}

配置返回json格式数据

# 展示可用的回调插件列表
ansible-doc -t callback -l|grep json

# 检查配置文件所在路径
ansible --version|grep 'config file'

# 编辑配置文件
vi /etc/ansible/ansible.cfg

# 新增配置（如果有则改，无则加）
stdout_callback = json
#### 确保 stdout_callback 在 whitelist 中
callback_whitelist = json, yaml
bin_ansible_callbacks = True

# 新增配置（非必须）
interpreter_python = /usr/local/python3/bin/python3

测试验证

[root@localhost ~]# ansible -m ping 127.0.0.1
