【經驗】ansible 批量推送公鑰

1.使用 ssh-keygen -t rsa生成密鑰對

 ssh-keygen -t rsa

 

2.推送單個公鑰到遠程機器

格式: ssh-copy-id -i ~/.ssh/id_rsa.pub username@[ip,hostname]html

ssh-copy-id -i ~/.ssh/id_rsa.pub username@192.168.100.2

 

3.添加ansible hosts

編輯/etc/ansible/hosts,沒有則建立些文件。tomcat

 

格式:【主機名】 【主機地址】 【主機密碼】  默認是root用戶來進行的ssh

[tomcat-servers]
1 ansible_ssh_user="tomcat"  ansible_ssh_host=192.168.100.1 ansible_ssh_pass="test"
2 ansible_ssh_user="tomcat"  ansible_ssh_host=192.168.100.2 ansible_ssh_pass="test"

 

新版的ansible(2.4) hosts有更新, 用如下方式:post

 
 
[tomcat-servers]
192.168.100.1   ansible_user=tomcat  ansible_ssh_pass="test"
192.168.100.2   ansible_user=tomcat  ansible_ssh_pass="test"

 

4.批量推送公鑰到遠程機器

機器多的狀況下,使用ssh-copy-id方法有些費時,使用ansible-playbook推送ymal,這裏使用到了authoried_keys模塊,能夠參考 http://docs.ansible.com/authorized_key_module.html測試

將如下文件命名爲:push.ssh.ymal this

 # Using alternate directory locations:
  - hosts: tomcat-servers
    user: tomcat
    tasks:
     - name: ssh-copy
       authorized_key: user=tomcat key="{{ lookup('file', '/home/tomcat/.ssh/id_rsa.pub') }}"
       tags:
         - sshkey

 

5.執行推送命令

ansible-playbook push.ssh.ymal 

 

6.如若報錯,解決

Using a SSH password instead of a key is not possible because Host Key checking is enabled and sshpass does not support this.  Please add this host's fingerprint to your known_hosts file to manage this host.

修改host_key_checking(默認是check的):spa

vi /home/xiangdong/ansible/ansible.cfg
# uncomment this to disable SSH key host checking
host_key_checking = False

 

7.測試

#查看各機器時間
ansible all -a date
#ansible all -m command -a date # 做用同上

#ping
 ansible all -m ping

 輸出結果:code

$ ansible all  -m ping 
192.168.100.1 | SUCCESS => {
    "changed": false, 
    "ping": "pong"
}
