ansible主机文件中的ansible远程服务器名称（jenkins从节点）

Question

I am not sure how to specify my host name in ansible host file. I am not able to ping my remote machine because of this.

jenkins slave node name: agent007

Answer 1

Please make sure you have mapped the local DNS if you are trying to ping using hostname. Or else try Ip. Also you should make the password-less authentication for this. Use ssh-keygen and copy the pub key to the remote server in authorized hosts file.

Answer 2

The remote host you are trying to reach needs to be defined in your ansible inventory file, usually named hosts :

agent007 ansible_ssh_host=<ip addr>

Then you can explicitly use this inventory file with the -i option

ansible-playbook -i hosts firstplaybook.yml

Answer 3

1. In /etc/ansible/hosts list the host machines: [localhost] IP address of local host
2. u should have passwordless connection using ssh-keygen -t rsa which will give ua rsa.pubkey which should be copied on authorization keys of host machine
3. then u can run the playbook
