1、mysql死锁
2、查看时区:
show variables like "%time_zone%";
3、mysql datetime字段使用DATE_FORMAT()函数,我是链接
4、MySQL retrieves and displays DATETIME values in 'YYYY-MM-DD hh:mm:ss' format. The supported range is '1000-01-01 00:00:00' to '9999-12-31 23:59:59' . TheTIMESTAMP data type is used for values that contain both date and time parts.TIMESTAMP has a range of '1970-01-01 00:00:01' UTC to '2038-01-19 03:14:07' UTC.
5、linux没有设置systemctl服务的话,需要去安装的bin下执行nohup mysqld &;
