データベースサーバーは、サーバー上のデータベースをクライアントから操作できるようにするためのサーバー。WordPressもデータベースを使う必要があるので、ここでは、リレーショナル型データベースのデータベースサーバーであるMySQLの導入手順を紹介します。
MySQLの導入手順
(1)MySQLのインストール
[root@ufuso ~]# yum -y install mysql-server ← mysql-serverインストール Installed: mysql-server.x86_64 0:5.1.61-4.el6 Dependency Installed: mysql.x86_64 0:5.1.61-4.el6 perl-DBD-MySQL.x86_64 0:4.013-3.el6 Complete! |
(2)MySQLの設定
[root@ufuso ~]# vi /etc/my.cnf ← MySQL設定ファイル編集 [mysqld] datadir=/var/lib/mysql socket=/var/lib/mysql/mysql.sock user=mysql # Disabling symbolic-links is recommended to prevent assorted security risks symbolic-links=0 character-set-server = utf8 ← 追記。文字コードをUTF-8にする [mysqld_safe] log-error=/var/log/mysqld.log pid-file=/var/run/mysqld/mysqld.pid |
(3)MySQLの起動
[root@ufuso ~]# /etc/rc.d/init.d/mysqld start ← MySQL起動 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 ufuso.dip.jp 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 ] [root@ufuso ~]# chkconfig mysqld on ← MySQL自動起動設定 |
(4)MySQLデータベース初期設定
[root@ufuso ~]# mysql_secure_installation ← MySQL初期設定 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): ← ENTERキーを押す 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] ← ENTERキーを押す New password: ← rootパスワードを設定してENTERキーを押す Re-enter new password: ← rootパスワードを再度入力してENTERキーを押す 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] ←匿名ユーザー削除のためENTERキーを押す ... 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] ←リモートからのrootログイン禁止のためENTERキーを押す ... 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] ←testデータベース削除のためENTERキーを押す - 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] ←table再読込みのためENTERキーを押す ... 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!
