但是奇怪的是，这是在cmd下面报错。我用Navicat for Mysql 连接到MySQL，是可以正常连接的。
网上找了很多文章，有以下几种解决方案，可能适合你的情况：
1、删除data目录下的ib_logfile0和ib_logfile1文件，重启MySQL。 
   -----这种多发生在启动MySQL服务时，不能开启MySQL服务。但是我的服务可以正常的开启和关闭：

2、在my.ini mysqld 下添加 explicit_defaults_for_timestamp=true
   -----我添加之后，还是原来的错误。
3、手动的在服务里面，重启MySQL服务
   -----这种可能性表示怀疑。手动的跟命令行下，应该都一样吧

中午吃饭回来继续解决。
可发现，报错不一样了
[Warning] TIMESTAMP with implicit DEFAULT --explicit_defaults_for_timestamp
然后又把添加的参数给注释掉。
再登录的时候，居然可以登录了。

真的百思不得其解。刚刚接触MySQL，很多问题不会，只能通过度娘以及认识的大牛们。

哈哈 现在要下班了，刚刚在Linux环境下同样遇见这个问题：

但是这样就可以登录了：

度娘还是那些，这次请教大牛。这是与大牛的对话：
[Warning] TIMESTAMP with implicit DEFAULT --explicit_defaults_for_timestamp
[Warning] TIMESTAMP with implicit DEFAULT --explicit_defaults_for_timestamp

总算明白是怎么会事儿了！
回家！
