＃ dnf -y install mysql8.4-server |
charset.cnf 下記の内容で新規作成
デフォルトの文字コードを設定 絵文字等 4 バイト長の文字を扱う場合はutf8mb4
|
1 2 3 4 5 6 7 |
＃ vi /etc/my.cnf.d/charset.cnf [mysqld] character-set-server = utf8mb4 [client] default-character-set = utf8mb4 |
|

＃ systemctl enable --now mysqld Created symlink /etc/systemd/system/multi-user.target.wants/mysqld.service → /usr/lib/systemd/system/mysqld.service. |
完了したら、 「mysql_secure_installation」 コマンドを使用してrootユーザーのパスワードを設定し、いくつかの基本的なポリシーを設定します
# 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
Please set the password for root here.
New password:[password]
Re-enter new password:[password]
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!
WordPressインストール
1.MySQL8.4の設定変更
MySQL8.4では、"mysql_native_password"認証プラグインがデフォルトで無効になり、"caching_sha2_password"になっています。
"mysql_native_password"認証プラグインを利用するため設定ファイルの [mysqld] セクションに、以下のように設定を追加します。
|
1 2 3 4 5 6 7 8 |
＃ vi /etc/my.cnf.d/charset.cnf [mysqld] character-set-server = utf8mb4 mysql_native_password=on ←追加 [client] default-character-set = utf8mb4 |
|
1 |
# systemctl restart mysqld |
2. Word Press 用のデータベースを作成
例としてデータベース[wp_db] データベースユーザー[wp_user] パスワード[?Ww123456]とします
# mysql -u root -p
Enter password: ←MySQL 用root パスワード入力します（画面上は表示されません）

define('FS_METHOD', 'direct');
5.ファイルの移動
①/var/www/html/[wordpress用ドメイン名]の下に展開した中身を移動
|

# cd /var/www/html/[FQDN] # mv wordpress/* . |
移動されたことを確認後 wordpressディレクトリーとダウンロードしたlatest-ja.tar.gzを削除
|
1 2 3 |
# cd /var/www/html/[FQDN] # rm -R -f wordpress # rm latest-ja.tar.gz |
wordpressディレクトリの所有者をapacheにします。
