④MariaDBサービスの起動と有効化

# systemctl start mysql

1	# systemctl start mysql

再起動時にサービスを開始するようにする

# systemctl enable mariadb
Created symlink /etc/systemd/system/mysql.service → /usr/lib/systemd/system/mariadb.service.
Created symlink /etc/systemd/system/multi-user.target.wants/mariadb.service → /usr/lib/systemd/system/mariadb.service.

# systemctl enable mariadb

Created symlink /etc/systemd/system/mysql.service → /usr/lib/systemd/system/mariadb.service.

Created symlink /etc/systemd/system/multi-user.target.wants/mariadb.service → /usr/lib/systemd/system/mariadb.service.

⑤MariaDBのインストールのセキュリティー

MariaDBサーバーのrootユーザーのパスワードを変更しておきます。

# mysql_secure_installation

NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB
      SERVERS IN PRODUCTION USE!  PLEASE READ EACH STEP CAREFULLY!

In order to log into MariaDB to secure it, we'll need the current
password for the root user. If you've just installed MariaDB, and
haven't set the root password yet, you should just press enter here.

Enter current password for root (enter for none): [Enter]
OK, successfully used password, moving on...

Setting the root password or using the unix_socket ensures that nobody
can log into the MariaDB root user without the proper authorisation.

You already have your root account protected, so you can safely answer 'n'.

Switch to unix_socket authentication [Y/n] y
Enabled successfully!
Reloading privilege tables..
 ... Success!


You already have your root account protected, so you can safely answer 'n'.

Change the root password? [Y/n] y
New password: [Password]
Re-enter new password: [Password again]
Password updated successfully!
Reloading privilege tables..
 ... Success!


By default, a MariaDB installation has an anonymous user, allowing anyone
to log into MariaDB 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? [Y/n] 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? [Y/n] y
 ... Success!

By default, MariaDB 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? [Y/n] 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? [Y/n] y
 ... Success!

Cleaning up...

All done!  If you've completed all of the above steps, your MariaDB
installation should now be secure.

Thanks for using MariaDB!

# systemctl restart apache2

# zypper install phpMyAdmin

# systemctl restart apache2

②ブラウザで http://<IPアドレス>/phpMyAdmin にアクセスする
下記のログイン画面が表示されるので
Username : root
Password: MariaDBのセキュリティーインストールで設定したrootユーザーのパスワード
Go クリック

下記phpMyAdminの設定画面が表示される

1.3 MariaDB データベース＋ユーザー作成例

次にインストールするwordpress用ユーザー、パスワード、データベースを作成してみる
データベース　:　 wp_db
ユーザー　:　wp_user
パスワード　:　?WHxx333Yo

# mysql -u root -p

Enter password:

2. WordPress インストール

2.1 必要なライブラリーインストール

# zypper install php-gd php-pdo php-mysql php-mbstring php-simplexml php-curl apache2-mod_php8

1	# zypper install php-gd php-pdo php-mysql php-mbstring php-simplexml php-curl apache2-mod_php8

2.2 WordPressダウンロードとインストール

# cd /srv/www/htdocs/
# wget http://ja.wordpress.org/latest-ja.tar.gz
# tar zxvf latest-ja.tar.gz

# cd /srv/www/htdocs/

# wget http://ja.wordpress.org/latest-ja.tar.gz

# tar zxvf latest-ja.tar.gz

2.3 設定ファイルの編集

# cd /srv/www/htdocs/wordpress/
# cp wp-config-sample.php wp-config.php

1 2	# cd /srv/www/htdocs/wordpress/ # cp wp-config-sample.php wp-config.php

# vi wp-config.php

/** The name of the database for WordPress */
define( 'DB_NAME', 'wp_db' ); [データベース名]

/** Database username */
define( 'DB_USER', 'wp_user' ); [ユーザー名]

/** Database password */
define( 'DB_PASSWORD', '?WHxx333Yo' ); [パスワード]

/** Database hostname */

また、最終行に以下の分を追加します。 これをしないと、プラグインを追加するときにFTP接続情報なるものを聞かれます。
define('FS_METHOD', 'direct');

# vi wp-config.php

/** The name of the database for WordPress */

define( 'DB_NAME', 'wp_db' ); [データベース名]

/** Database username */

define( 'DB_USER', 'wp_user' ); [ユーザー名]

/** Database password */

define( 'DB_PASSWORD', '?WHxx333Yo' ); [パスワード]

/** Database hostname */

また、最終行に以下の分を追加します。これをしないと、プラグインを追加するときにFTP接続情報なるものを聞かれます。

define('FS_METHOD', 'direct');

/srv/www/htdocs/[web公開ディレクトリー]の下に展開した中身を移動します

# cd /srv/www/htdocs/
# mv wordpress/* .

1 2	# cd /srv/www/htdocs/ # 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

# cd /srv/www/htdocs/
# rm -Rf wordpress
# rm latest-ja.tar.gz

# cd /srv/www/htdocs/

# rm -Rf wordpress

# rm latest-ja.tar.gz

wordpressディレクトリの所有者をapacheにします。
これをしないとプラグインのインストールなどの際に、ディレクトリを作成できないとか言われてしまします。

# chown -R wwwrun:wwwrun /srv/www/htdocs/
# chmod 775 -R /srv/www/htdocs/

1 2	# chown -R wwwrun:wwwrun /srv/www/htdocs/ # chmod 775 -R /srv/www/htdocs/

# systemctl restart apache2

1	# systemctl restart apache2

2.4 起動確認

ブラウザで　http://<サーバー名>/wp-admin/install.php　に接続し、ユーザー名、パスワード等必要事項を入力し、インストールを開始してください
通常は、これで下図のWordpress管理画面にアクセスする「ユーザー名」「パスワード」等初期設定インストール画面が表示されますので
Site Title　:　任意のタイトル
Username　:　任意のユーザー名
Password　:　任意のパスワード
Your Email　:　管理者のメールアドレス
を入力し、「WordPressをインストール」クリック

WordPress管理画面への「ユーザー名またはメールアドレス」「パスワード」の入力画面が出ます。
