1、Can‘t connect to local MySQL server through socket ‘tmpmysql.sock‘ (2)

原因是mysql根本沒有啟動

2、Access denied for user ‘root‘@‘localhost‘ (using password YES)

解決方法：

重置密碼就行，重新執行所有授權就行

3、com.mysql.jdbc.MysqlDataTruncation Data truncation Incorrect datetime value ‘0000-00-00 000000‘ for column

分析：

ONLY_FULL_GROUP_BY,STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

NO_ZERO_IN_DATE,NO_ZERO_DATE是無法默認為‘0000-00-00 00:00:00’的根源，去掉之後再次新建表就可以了

註：
NO_ZERO_IN_DATE：在嚴格模式下，不允許日期和月份為零
NO_ZERO_DATE：設置該值，mysql數據庫不允許插入零日期，插入零日期會拋出錯誤而不是警告。

測試新建表，ok。可以了。

4、k8s中java程序中的redis連接容器外部reids總是連接不上導致容器啟動失敗，查看tomacat日誌得知

解決

把java程序的xml 配置文件的reids端口 改成 6379 就可以，不要使用變量

mysql自身報錯、java、reids連接mysql數據庫報錯匯總
