运行show table status;导致错误.并且错误未显示我登录的用户名!
就好像,对于这个命令,mysql会忘记我是谁.其他选择语句工作正常.有谁能解释一下？怎么修？谢谢.

有人可以简单地解释我如何恢复冲突中的文件(接受他们的副本),同时恢复我对没有冲突的文件的更改.
我知道,ansible支持这种形式的模板中的循环:
{% for host in groups['all'] %}
"{{ host }}"{% if not loop.last %},{% endif %}
{% endfor %}
当我运行ansible时,这会循环遍历hosts文件中的所有内容,正如人们所期望的那样.
当我使用--limit命令行参数运行ansible时,我想只遍历符合限制的主机.有没有办法在jinja2模板中表达这个循环？
