How to remove the error The table '/tmp/mysql/#sql_xxxxx' is full?

Question

MySQL

Ubuntu server 15.10, php5.6, nginx 1.9.3, mysql 5.7 in a virtual machine under Hyper-V in Windows 10
I set up seo-url in opencart 2, which is in the site subdirectory on joomla 3.5 After enabling seo in the opencart settings
In the mysql log
[ERROR] InnoDB: Tablespace innodb_temporary ran out of space errors appear . Please add another file or use 'autoextend' for the last file in setting innodb_temp_data_file_path
[ERROR] /usr/sbin/mysqld: The table '/tmp/mysql/#sql_c76e_2' is full [ERROR] /usr/sbin/mysqld: The table '/tmp/mysql/#sql_c76e_3' is full
I did this
mkdir /tmp/mysql
chown mysql:mysql /tmp/mysql
service mysql restart
There are rights, but there is not a single file in /tmp/mysql/.
In mysqld.cnf
