I run wordpress website using Ubuntu 16.04 + Nginx + Mariadb 10.0.x + Php7.

I saw article about upgrade mariadb from 10.0 to 10.1. but i cant find to 10.2

Please let me know how do i that

Thank you.

The suggested upgrade procedure is:

Set innodbfastshutdown to 0 (this step is not necessary when upgrading to MariaDB 10.2.5 or later - omitting it can make the upgrade process far faster - see MDEV-12289).
Shutdown MariaDB 10.1,
Take a backup (this is the perfect time to take a backup of your databases)
Uninstall MariaDB 10.1
Install MariaDB 10.2 [2]
Run mysqlupgrade
Ubuntu and Debian packages do this automatically when they are installed; Red Hat, CentOS, and Fedora packages do not
upgrade does two things:
Upgrades the permission tables in the mysql database with some new fields
Does a very quick check of all tables and marks them as compatible with MariaDB 10.2
In most cases this should be a fast operation (depending of course on the number of tables)
Add new options to my.cnf to enable features
If you change my.cnf then you need to restart mysqld
