Just add the line:

inside file:

sudo service mysql restart

there you go....

  • I am having the same issue and following these steps did not fix the problem:

    1. add sqlmode = “NOAUTOCREATEUSER,NOENGINESUBSTITUTION” to /etc/mysql/mysql.conf.d/mysqld.cnf
    2. sudo service mysql restart


Your MySQL configuration files are located in /etc/mysql. By default, mode is not set, so you’ll need to scan the files and find where [mysqld] is defined for your installation and then under that tag, add:


.. and then restart MySQL. If you set this from the CLI, without using the configuration files and restarting MySQL, it won’t persist.


mysqld_safe] section of /etc/my.cnf! Because it didn’t work when the server rebooted, I searched for other .cnf files. Correctly adding it to the [mysqld] section of /etc/my.cnf works perfectly.

I came across this solution online by Nathaniel Hammond:

The implementation is swift and takes just a couple of seconds or minutes:

  1. Log into your server as root
  2. Get script wget
  3. Make is executable chmod +x
  4. Run the script ./

You can keep the script where you downloaded it for future mods or references or you can rm -rf and delete the shell script.

You will then have MySQL 5.7 without strict mode.
