Q1：pip安装ansible附加包时编译错误

A1：未安装Python dev库

1 2	$ sudo apt-get install python-dev $ sudo apt-get install libffi-dev

Q2：源码编译或无法运行，提示没有hosts文件

1 2 3

$ ansible all -m ping [WARNING]: Host file not found: /etc/ansible/hosts [WARNING]: provided hosts list is empty, only localhost is available

A2：在源码的example目录中可以找到hosts文件

1 2	#mkdir /etc/ansible #cp -r /home/ansible/ansible/example/* /etc/ansible

Q3：Failed to connect to the host via ssh错误

1 2 3 4 5 6

$ansible all -m ping -u root 192.168.3.2 | UNREACHABLE! => {     "changed": false,     "msg": "Failed to connect to the host via ssh.",     "unreachable": true }

A3：两种方法

在/etc/ansible/hosts配置将注释驱动

1 2	[ssh_connection] scp_if_ssh = True

或者命令中带有--ssh-extra-args="-o ControlPath=none" --sftp-extra-args="-o ControlPath=none

Q4：场景为已经配置好的机器，公钥已经发送，但是无法联通

1 2 3 4 5 6

$ ansible share -m ping -u root 192.168.30.200 | UNREACHABLE! => {     "changed": false,     "msg": "SSH Error: data could not be sent to the remote host. Make sure this host can be reached over ssh",     "unreachable": true }

A4：开启远程被控机sftp权限
原因：在/etc/ansible/ansible.cfg中开启下列选项

1 2	[ssh_connection] scp_if_ssh = True

配置后需要检查远程被控机器的ssh是否打开sftp功能，否则无法联通

1 2	vi /etc/ssh/sshd_config Subsystem sftp /usr/lib/openssh/sftp-server
