solution01:
ansible_sftp 传输失败导致无法连接,检查客户端发现/usr/lib/openssh/sftp-server不存在;
添加软连接问题解决
ln -s /usr/libexec/openssh/sftp-server /usr/lib/openssh/sftp-server

# ll /usr/lib/openssh/sftp-server 
lrwxrwxrwx 1 root root 32 Jun  8 15:32 /usr/lib/openssh/sftp-server -> /usr/libexec/openssh/sftp-server

solution02:
将ansible升级到2.9可以解决问题;
