4．/etc/php.ini変更

下記を追記
extension=mysql.so

5．install.phpアクセスでエラー表示

「お使いのサーバーの PHP では WordPress に必要な MySQL 拡張を利用できないようです。」
用意したデータベースwordpressに対するユーザwordpressのhostが%ではダメ。localhostに変更。

mysql> select host,user,password from user;
+-----------+-----------+-------------------------------------------+
| host      | user      | password                                  |

| localhost | wordpress |*EC13F3D2A50CDD8B3E5D76514D5FD311E6276EA5  |
+-----------+-----------+-------------------------------------------+

6．WP Multibyte Patch有効化でエラー表示

「お使いの WP Multibyte Patch を有効にするには、PHP の mbstring 関数が必要です。」
対処は、php-mbstringをインストールすること。

[root ~]# yum install php-mbstring.i386
Loaded plugins: fastestmirror, priorities

Complete!

7．プラグイン更新やテーマインストール時のFTP接続設定

/opt/wordpress/wp-config.phpに下記を追記。

define('FS_METHOD', 'direct');

8．プラグイン更新やテーマインストールのための設定

[root ~]# mkdir /opt/wordpress/wp-content/upgrade
[root ~]# chown root:httpd実行グループ /opt/wordpress/wp-content/upgrade
[root ~]# chown root:httpd実行グループ /opt/wordpress/wp-content/plugins
[root ~]# chown root:httpd実行グループ /opt/wordpress/wp-content/themes
[root ~]# chmod 775 /opt/wordpress/wp-content/upgrade
[root ~]# chmod 775 /opt/wordpress/wp-content/plugins
[root ~]# chmod 775 /opt/wordpress/wp-content/themes

以上でバッチリ！

ちなみに、アクセスURLのパス部分に関するhttpd.conf等でのAlias設定などは、必要に応じて別途実施。
