MySQLサーバの設定

MySQLサーバのインストール

sudo yum install mysql-server
sudo chkconfig mysqld on
sudo service mysqld start

MySQLのrootユーザの設定

デフォルトではMySQLのrootユーザにパスワードが設定されていないため, 新しくパスワードを設定します.

これはLinuxのrootアカウントとは無関係です.

sudo /usr/bin/mysql_secure_installation

以下のように,指示に従ってパスワードの設定を行ってください.

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


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

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

Setting the root password ensures that nobody can log into the MySQL
root user without the proper authorisation.

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


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? [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, 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? [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 MySQL
installation should now be secure.

Thanks for using MySQL!

WordPressのデータベースとユーザ作成

sudo mysql -u root -p

でMySQLに接続し,以下のSQLを実行します.ユーザー名,パスワード及びデータベース名は任意に変更してください.

CREATE DATABASE wordpress DEFAULT CHARACTER SET utf8;
GRANT ALL PRIVILEGES ON wordpress.* TO wordpress IDENTIFIED BY 'wp-password' WITH GRANT OPTION;

PHP-MySQLモジュールのインストール

sudo yum install --enablerepo=remi-php55 php-mysql
sudo service php-fpm restart

Nginxの設定変更

sudo vi /etc/nginx/conf.d/default.conf

location / の中の index 設定に,index.phpを追加します.

        index  index.php index.html index.htm;

設定のテストと反映

sudo nginx -t
sudo service nginx reload

WordPressのインストール

ファイルの展開

設置する場所は変更可能です.

wget https://ja.wordpress.org/wordpress-4.2.2-ja.tar.gz
tar zxvf wordpress-4.2.2-ja.tar.gz
sudo mv wordpress /usr/share/nginx/html/
sudo chown -R nginx /usr/share/nginx/html/wordpress/

ブラウザからアクセス

http://IPアドレス/wordpress/

にアクセスして,手順に従いWordPressのインストールを行います.

sudo vi /etc/nginx/conf.d/default.conf

(参考)パーマリンクの設定

Nginxでは.htaccessが使えませんが,WordPressに合わせて設定を変更することで,パーマリンクを利用することができます.

以下に default.conf に追記する一例を示します.

location /wordpress {
    root   /usr/share/nginx/html;
    index  index.php index.html index.htm;
    try_files $uri $uri/ /wordpress/index.php?q=$uri&$args;
}

変更したファイル

/etc/nginx/conf.d/default.conf

server {
    listen       80;
    server_name  localhost;

    location / {
        root   /usr/share/nginx/html;
        index  index.php index.html index.htm;
    }

    location /wordpress {
        root   /usr/share/nginx/html;
        index  index.php index.html index.htm;
        try_files $uri $uri/ /wordpress/index.php?q=$uri&$args;
    }

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }

    # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
    #
    location ~ \.php$ {
        root           /usr/share/nginx/html;
        fastcgi_pass   127.0.0.1:9000;
        fastcgi_index  index.php;
        fastcgi_param  SCRIPT_FILENAME  $document_root$fastcgi_script_name;
        include        fastcgi_params;
    }

}
