ansible主控端

192.168.26.129
|
ansible被控制端
|
192.168.26.130
|
ansible被控制端
|
1、ansible主配置文件/etc/ansible/ansible.cfg和受管主机/etc/ansible/hosts里面的配置
[root@192 ~]# cat /etc/ansible/ansible.cfg |grep -v "^#"|grep -v "^$"
[defaults]
[inventory]
[privilege_escalation]
[paramiko_connection]
[ssh_connection]
[persistent_connection]
[accelerate]
[selinux]
[colors]
[diff]
[root@192 ~]# cat /etc/ansible/hosts |grep -v "^#"|grep -v "^$"
[test]
192.168.26.129
192.168.26.130
2、使用ping模块探测其它主机
[root@192 ~]# ansible test -m ping -k
SSH password:
192.168.26.130 | FAILED! => {
"msg": "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."
192.168.26.129 | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/bin/python"
},
"changed": false,
"ping": "pong"
3、可以看到192.168.26.130的主机不能到达,原因是这台主机是新加的机器,信息没写入known_hosts文件
4、在/etc/ansible/hosts把host_key_checking = False注释取消
[root@192 ~]# cat /etc/ansible/ansible.cfg |grep -v "^#"|grep -v "^$"
[defaults]
host_key_checking = False
[inventory]
[privilege_escalation]
[paramiko_connection]
[ssh_connection]
[persistent_connection]
[accelerate]
[selinux]
[colors]
[diff]
5、再次执行ping模块探测其它主机
[root@192 ~]# ansible test -m ping -k
SSH password:
192.168.26.129 | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/bin/python"
},
"changed": false,
"ping": "pong"
192.168.26.130 | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/bin/python"
},
"changed": false,
"ping": "pong"
6、可以看到正常的探测到其它的机器,这个方法适用大批量的新增主机至/etc/ansible/hosts主机配置文件中
