解决办法:

  1:查看mysql配置文件位置

[root@localhost ~]# ps -ef | grep mysqlmysql 838 1 0 02:21 ? 00:00:00 /usr/sbin/mysqld --defaults-file=/etc/my.cnfroot 2035 1706 0 02:29 pts/0 00:00:00 grep --color=auto mysql

  2:打开配置文件

[root@localhost ~]# vim /etc/my.cnf

  3:修改配置:如果没有该配置项,添加一个即可

sql_mode=STRICT_TRANS_TABLES,NO_ZERO_IN_DATE,NO_ZERO_DATE,ERROR_FOR_DIVISION_BY_ZERO,NO_AUTO_CREATE_USER,NO_ENGINE_SUBSTITUTION

  4:重启mysql

[root@localhost ~]# systemctl restart mysql
