[Warning] TIMESTAMP with implicit DEFAULT value is deprecated

启动mysql时，报如下警告信息：

[Warning] TIMESTAMP with implicit DEFAULT value is deprecated. Please use --explicit_defaults_for_timestamp server option (see documentation for more details).

修改方法：

在配置my.cnf中加入，然后启动mysql

[mysqld]
explicit_defaults_for_timestamp=true

explicit_defaults_for_timestamp参数说明可以参考上一篇文章：
