Ansible常用Ad-Hoc模式

1、authorized_key

# 给主机添加密钥认证
ansible all -m authorized_key -a key="{{ lookup('file', '~/.ssh/id_rsa.pub') }} user=root" --ask-pass -u root

2、ping

 ansible cdh_uat -m ping
172.17.208.73 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    },
    "changed": false,
    "ping": "pong"
}
172.17.208.72 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    },
    "changed": false,
    "ping": "pong"
}
172.17.208.74 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    },
    "changed": false,
    "ping": "pong"
}
172.17.208.75 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/bin/python"
    },
    "changed": false,
    "ping": "pong"
}

3、group

# 添加组
ansible all -m group -a "gid=41000 name=ansible_test state=present system=no"
# 删除组
ansible all -m group -a "gid=41000 name=ansible_test state=absent"

4、user

# 创建用户
ansible all -m user -a 'uid=41000 name=ansible_test state=present group=ansible_test shell=/bin/bash'

5、copy

# 从文件复制
ansible all -m copy -a "src=/Users/user/Downloads/hosts dest=/etc/hosts"
#从内容复制
ansible all -m copy -a "content='hello world\n' dest=/root/hi.txt"

6、fetch

ansible 10.9.251.30 -m fetch -a 'src=/etc/hosts dest=./hosts'

10.9.251.30 | CHANGED => {
    "changed": true,
    "checksum": "4b8e199a4422de7f7d5854f9e5cbc8656f557162",
    "dest": "/Users/user/Downloads/hosts/10.9.251.30/etc/hosts",
    "md5sum": "11196d628534ecf0a5eada5b6077fdc9",
    "remote_checksum": "4b8e199a4422de7f7d5854f9e5cbc8656f557162",
    "remote_md5sum": null
}

7、command

不支持变量

ansible all -m command -a 'ifconfig'

ansible all -m command -a 'chdir=/tmp mkdir ansible_tmp'

8、shell

ansible all -m shell -a 'echo hello | passwd --stdin ansible_test'

9、file

# 创建指定目录
ansible all -m file -a 'path=/tmp/hello.dir state=directory'

10、cron

# 每3min同步一次时间，任务名称叫ntp date
ansible all -m cron -a 'minute=*/3 job="/usr/sbin/ntpdate time.pool.aliyun.com >/dev/null 2>&1" state=present name="ntp date"'

11、yum

ansible all -m yum -a 'name=htop state=installed'
ansible all -m yum -a 'name=nginx state=installed'

12、service（Centos6）

ansible all -m service -a 'name=nginx state=started'

---

13、systemd（Centos7）

ansible all -m systemd -a 'name=nginx state=started enabled=true'
