ansible批量修改主机名称

1 修改host文件
cat >> /etc/ansible/hosts << EOF
[test]
192.168.1.202 hostname=spider-01 ansible_ssh_port=2968 ansible_ssh_user=root ansible_ssh_pass=1q2w3e4r
192.168.1.201 hostname=spider-02 ansible_ssh_port=22 ansible_ssh_user=root ansible_ssh_pass=1q2w3e4r
EOF

2 编写playbook剧本
cat > modify_hostname.yml << EOF

hosts: test
remote_user: root
tasks:
name: change name
raw: “echo {{hostname|quote}} > /etc/hostname”
name:
shell: hostname {{hostname|quote}}
EOF
3 检查语法 执行
[root@web ansible-playbook]# ansible-playbook --syntax-check modify_hostname.yml
[root@web ansible-playbook]# ansible-playbook -C modify_hostname.yml //预执行
[root@web ansible-playbook]# ansible-playbook modify_hostname.yml //真正执行
