mysql自身报错、java、reids连接mysql数据库报错汇总

1、Can't connect to local MySQL server through socket 'tmpmysql.sock' (2)

原因是mysql根本没有启动

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

解决方法：

重置密码就行，重新执行所有授权就行

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是无法默认为‘0000-00-00 00:00:00’的根源，去掉之后再次新建表就可以了

注：
NO_ZERO_IN_DATE：在严格模式下，不允许日期和月份为零
NO_ZERO_DATE：设置该值，mysql数据库不允许插入零日期，插入零日期会抛出错误而不是警告。

测试新建表，ok。可以了。

4、k8s中java程序中的redis连接容器外部reids总是连接不上导致容器启动失败，查看tomacat日志得知

解决

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