无法通过ssh连接到主机：root@node1：权限被拒绝

在执行apache任务时报错

[root@ansible ansible]# ansible-playbook apache.yml 

PLAY [use apache role] ********************************************************************************************************

TASK [Gathering Facts] ********************************************************************************************************
fatal: [node1]: UNREACHABLE! => {"changed": false, "msg": "Failed to connect to the host via ssh: root@node1: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).", "unreachable": true}
翻译报错：
#致命：[node1]：无法访问！=>｛“changed”：false，“msg”：“无法通过ssh连接到主机：root@node1：权限被拒绝（公钥、gssapi keyex、带麦克风的gssapi、密码）。“，”无法访问“：true｝

解决：

[root@ansible ansible]# ssh-copy-id root@node1   
/usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub"
/usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed
/usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys
root@node1's password: 

Number of key(s) added: 1

Now try logging into the machine, with:   "ssh 'root@node1'"
and check to make sure that only the key(s) you wanted were added.

原因：ssh远程密钥没有对接
