【故障集合】综合架构之ansible服务错误集合（持续补充中）

1、Failed to connect to the host via ssh: Permission denied 权限拒绝

没有ssh秘钥认证。
ansible是基于ssh秘钥认证的，估生成秘钥，重新分发下公钥就ok了

[root@m01 /server/ansible-playbook]# ansible-playbook -C ansible-var01.yml 

PLAY [oldboy] ************************************************************************************************************************

TASK [Gathering Facts] ***************************************************************************************************************
fatal: [172.16.1.41]: UNREACHABLE! => {"changed": false, "msg": "Failed to connect to the host via ssh: Permission denied (publickey,password).", "unreachable": true}

[root@m01 /server/ansible-playbook]# 

2、The task includes an option with an undefined variable 任务包含一个带有未定义变量的选项

根据错误的行数提醒，shell模块的命令书写错误

TASK [make dir] **********************************************************************************************************************
fatal: [172.16.1.41]: FAILED! => {"msg": "The task includes an option with an undefined variable. The error was: 'dict object' has no attribute 'stdout'\n\nThe error appears to be in '/server/ansible-playbook/ansible-var04.yml': line 12, column 7, but may\nbe elsewhere in the file depending on the exact syntax problem.\n\nThe offending line appears to be:\n\n      register: time\n    - name: make dir\n      ^ here\n"}
