CentOSにWordPress(日本語版)をインストールする手順

CentOS release 6.5 (Final)

必要なパッケージのインストール

yum instal httpd mysql-server php php-mysql php-mbstring vsftpd

apache準備

# vi /etc/httpd/conf/httpd.conf

httpd.conf

ServerName www.example.com:80 #<- コメントアウトを外して変更
DirectoryIndex index.html index.html.var index.php #<- index.phpを追加
AddType application/x-httpd-php .php　#<- 追加
AllowOverride All #<- None から Allへ変更　.htaccessの許可(WPパーマリンク設定とか)

# service httpd start
httpd を停止中:                                            [  OK  ]
httpd を起動中:                                            [  OK  ]
# chkconfig httpd on

mysql準備

初期設定

# vi /etc/my.cnf

my.cnf

[mysqld]
datadir=/var/lib/mysql
socket=/var/lib/mysql/mysql.sock
user=mysql
symbolic-links=0
character-set-server = utf8 #<- 追加

# service mysqld start
MySQL データベースを初期化中:  Installing MySQL system tables...
OK
Filling help tables...
OK

To start mysqld at boot time you have to copy
support-files/mysql.server to the right place for your system

PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !
To do so, start the server, then issue the following commands:

/usr/bin/mysqladmin -u root password 'new-password'
/usr/bin/mysqladmin -u root -h localhost.localdomain password 'new-password'

Alternatively you can run:
/usr/bin/mysql_secure_installation

which will also give you the option of removing the test
databases and anonymous user created by default.  This is
strongly recommended for production servers.

See the manual for more instructions.

You can start the MySQL daemon with:
cd /usr ; /usr/bin/mysqld_safe &

You can test the MySQL daemon with mysql-test-run.pl
cd /usr/mysql-test ; perl mysql-test-run.pl

Please report any problems with the /usr/bin/mysqlbug script!

                                                           [  OK  ]
mysqld を起動中:                                           [  OK  ]
# chkconfig mysqld on

初期設定

# mysql_secure_installation


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): #<- 空エンター
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 #<- Y でroot用パスワードを設定する
New password: PASSWORD #<- 入力
Re-enter new password: PASSWORD　#<- 確認再入力
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 #<- 匿名ユーザーを削除
 ... 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 #<- リモートからのrootログインを許可しない
 ... 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 #<- テスト用DB削除
 - 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 #<- 再読み込み
 ... 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!
