| + | 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 fedora9.fedorasrv.com password 'new-password'\\ | ||
| + | |||
| + | Alternatively you can run:\\ | ||
| + | /usr/bin/mysql_secure_installation\\ | ||
| - | datadir=/var/lib/mysql | + | 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.\\ | ||
| - | socket=/var/lib/mysql/mysql.sock | + | See the manual for more instructions.\\ |
| - | # Default to using old password format for compatibility with mysql 3.x | + | You can start the MySQL daemon with:\\ |
| + | cd /usr ; /usr/bin/mysqld_safe &\\ | ||
| - | # clients (those using the mysqlclient10 compatibility package). | + | You can test the MySQL daemon with mysql-test-run.pl\\ |
| + | cd mysql-test ; perl mysql-test-run.pl\\ | ||
| - | old_passwords=1 | + | Please report any problems with the /usr/bin/mysqlbug script!\\ |
| - | default-character-set = utf8 | + | The latest information about MySQL is available on the web at\\ |
| + | http://www.mysql.com\\ | ||

| + | 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(rootパスワード設定)\\ | ||
| + | New password: ← rootパスワード応答\\ | ||
| + | Re-enter new password: ← rootパスワード応答(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!\\ | ||
