CentOS6 自宅データベースサーバMySQL構築手順です。
文字色の説明 ■説明文 ■コマンド（Input） ■注意事項
MySQLインストール
[root@hostname ~]# yum -y install mysql-server ⇐ mysql-serverをインストール
MySQL設定
[root@hostname ~]# 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 ⇐ 追加（MySQLサーバ文字コードをUTF-8）
[mysqld_safe]
log-error=/var/log/mysqld.log
pid-file=/var/run/mysqld/mysqld.pid
MySQL起動/自動起動設定
[root@hostname ~]#/etc/rc.d/init.d/mysqld start ⇐ MySQLを起動
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 centos.centossrv.com 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@hostname ~]# chkconfig mysqld on ⇐ MySQL自動起動設定
MySQL初期設定
[root@hostname ~]# 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): ⇐ 空ENTER
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] ⇐ 空ENTER（MySQLのrootパスワード設定）
New password: ⇐ MySQLOのrootパスワード入力（パスワードは不表示）
Re-enter new password: ⇐ MySQLのrootパスワード入力（確認）
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] ⇐ 空ENTER（匿名ユーザー削除）
… 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] ⇐ 空ENTER（リモートからのrootログイン禁止）
… 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] ⇐ 空ENTER(testデータベース削除)
– 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] ⇐ 空ENTER
… 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!
