installing almost done!!
you should do few steps below.

1. change mysql user password

echo "SET PASSWORD FOR wp_user@\"localhost\"=PASSWORD('newpasswordhere');" | mysql -u root

2. edit /var/www/${HOSTNAME}/public_html/wp-config.php (rewrite password phrase).
define('DB_PASSWORD', 'newpasswordhere');

3. make robots.txt likie below (/var/www/${HOSTNAME}/public_html/robots.txt).
=================================================
User-Agent: *
Disallow: /wp-admin/
Disallow: /wp-includes/
Disallow: /wp-content/
Disallow: /wp-content/plugins
Disallow: /wp-content/cache
Disallow: /wp-content/themes
Disallow: /*?
Disallow: /*.php$
Disallow: /*.css$
Disallow: /*.js$

User-agent: Googlebot-Image
Disallow: /

Sitemap: http://${HOSTNAME}/sitemap.xml
=================================================

4. start servers

/etc/init.d/php-fpm start
/etc/init.d/nginx start

5. access http://${HOSTNAME}/wp-admin/install.php
