我的几个报错：
1.远程复制失败
[root@localhost ~ ]#scp -r .ssh 192.168.10.145:/root/
root@192.168.10.145's password:
bash: scp: command not found
lost connection
解决思路：发现没装openssh-clients客户端工具
[root@centos6 ~ ]#rpm -qa openssh*
openssh-5.3p1-122.el6.x86_64
openssh-server-5.3p1-122.el6.x86_64
[root@centos6 ~ ]#yum install openssh-clients
3.
[root@ansible /etc/ansible ]#ansible-playbook -C nginx.yml
[WARNING]: While constructing a mapping from /etc/ansible/roles/nginx/tasks/main.yml, line 6, column 3, found a duplicate dict key (template). Using
last defined value only.
[WARNING]: Ignoring invalid attribute: with_item

装这几个工具是方便-键操作
yum install ntpdate -y
ansible all -a 'yum install ntpdate -y'
ansible all -a '/usr/sbin/ntpdate stdtime.gov.hk'
ansible all -a 'yum install tree -y'
ansible all -a 'yum install openssh-clients -y'
2.同步失败
[root@centos7 ~ ]#ansible all -a 'ntpdate time.nist.gov'
192.168.10.144 | FAILED | rc=1 >>
5 May 19:00:00 ntpdate[37327]: no server suitable for synchronization foundnon-zero return code
解决方法：
第1：先要确定，系统确实可以上网，ping baidu.com 能通就行
第2：/usr/sbin/ntpdate stdtime.gov.hk 就行了。
