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?

# パスワード品質チェックを有効にするか否か
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

# パスワード品質チェックを有効にした場合は強度を選択
Please enter 0 = LOW, 1 = MEDIUM and 2 = STRONG: 0　←各自任意でよい
Please set the password for root here.

# MySQL root パスワードを設定
New password:　　←　任意のパスワード

Re-enter new password:　←　再度同じパスワード

# 入力したパスワードで良いかの確認
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.

# 匿名ユーザーを削除するか否か
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.

# root ユーザーのリモートログインを無効とするか否か
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.

# テストデータベースを削除するか否か
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.

# 特権情報をリロードするか否か
Reload privilege tables now? (Press y|Y for Yes, any other key for No) : y
Success.

All done!

2.Wordpressインストール

# cd /var/www/html/[FQDN]
# wget http://ja.wordpress.org/latest-ja.tar.gz
# tar xvf latest-ja.tar.gz

# cd /var/www/html/[FQDN]

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

# tar xvf latest-ja.tar.gz

3.Wordpress設定ファイルの編集

# cd wordpress/
# cp wp-config-sample.php wp-config.php
# vi wp-config.php
 // ** Database settings - You can get this info from your web host ** //
/** The name of the database for WordPress */^
define('DB_NAME', 'wp_db');

/** Database username */
define('DB_USER', 'wp_user');

/** Database password */
define('DB_PASSWORD', '?W123456');

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');

# cd wordpress/

# cp wp-config-sample.php wp-config.php

# vi wp-config.php

// ** Database settings - You can get this info from your web host ** //

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