default-character-set = utf8mb4

[mysqld]

character-set-server = utf8mb4[client]

default-character-set = utf8mb4

＃systemctl enable --now mysqld

Once completed, set the password for the root user using the "mysql_secure_installation" command

＃mysql_secure_installation

Securing the MySQL server deployment.

Connecting to MySQL using a blank password.

VALIDATE PASSWORD COMPONENT can be used to test passwords
and improve security. It checks the strength of password
and allows the users to set only those passwords which are
secure enough. Would you like to setup VALIDATE PASSWORD component?

Press y|Y for Yes, any other key for No: y

There are three levels of password validation policy:

LOW Length >= 8
MEDIUM Length >= 8, numeric, mixed case, and special characters
STRONG Length >= 8, numeric, mixed case, special characters and dictionary file

Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 0　←Any
Please set the password for root here.

New password:　　←　Any  Mysql root password

Re-enter new password:　←　again  Mysql root password

Estimated strength of the password: 100
Do you wish to continue with the password provided?(Press y|Y for Yes, any other key for No) : y
By default, a MySQL installation has an anonymous user,
allowing anyone to log into MySQL without having to have
a user account created for them. This is intended only for
testing, and to make the installation go a bit smoother.
You should remove them before moving into a production
environment.

Remove anonymous users? (Press y|Y for Yes, any other key for No) : y
Success.

Normally, root should only be allowed to connect from
'localhost'. This ensures that someone cannot guess at
the root password from the network.

Disallow root login remotely? (Press y|Y for Yes, any other key for No) : y
Success.

By default, MySQL comes with a database named 'test' that
anyone can access. This is also intended only for testing,
and should be removed before moving into a production
environment.

Remove test database and access to it? (Press y|Y for Yes, any other key for No) : y
- Dropping test database...
Success.

- Removing privileges on test database...
Success.

Reloading the privilege tables will ensure that all changes
made so far will take effect immediately.

Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y
Success.

All done!

①Move the expanded contents under /var/www/html/[FQDN for wordpress].

# cd /var/www/html/[FQDN for wordpress]
# mv wordpress/* .

1 2	# cd /var/www/html/[FQDN for wordpress] # mv wordpress/* .

After confirming that the files have been moved, delete the wordpress directory and the downloaded latest-ja.tar.gz.

6.Start the wordpress installation.

Access http://[FQDN for wordpress]/wp-admin/install.php with a browser, enter your user name, password, and other necessary information, and start the installation.

Your server's PHP does not seem to be able to use the MySQL extensions required for WordPress." If you see this, install the following and restart apache and mysql

# dnf install php-mysqlnd
# systemctl restart mysqld
# systemctl restart httpd

# dnf install php-mysqlnd

# systemctl restart mysqld

# systemctl restart httpd
