mysql \[Err\] 1118 - Row size too large (> 8126).

问题

mysql5.7 在执行创建表或者增加字段时，发现row size长度过长，导致出现以下错误。

\[Err\] 1118 - Row size too large (> 8126). Changing some columns to TEXT or BLOB may help. In current row format, BLOB prefix of 0 bytes is stored inline.

解决方案

You may want to take a look at this article which explains a lot about MySQL row sizes. It's important to note that even if you use TEXT or BLOB fields, your row size could still be over 8K (limit for InnoDB) because it stores the first 768 bytes for each field inline in the page.

The simplest way to fix this is to use the Barracuda file format with InnoDB. This basically gets rid of the problem altogether by only storing the 20 byte pointer to the text data instead of storing the first 768 bytes.

方法一：改变一些字段varchar为TEXT or BLOB。 无效，不能解决问题。

最终解决方案

查询系统参数：

show variables like '%innodb\_strict\_mode%';

show variables like '%innodb\_log\_file\_size%';

修改前：

innodb\_strict\_modeON

innodb\_log\_file\_size536870912

修改mysql的配置文件， vi /etc/my.cnf

innodb\_log\_file\_size=1024M

innodb\_strict\_mode=0

innodb\_strict\_mode=0 这个一定不能漏，否则不能生效。 重启后：
