LAMP с использованием yum установка очень проста и занимает всего несколько минут. Это хороший вариант для начинающих, которые не чувствуют себя комфортно при установке из исходного кода. Кроме того, установка стека LAMP с использованием yum – это хороший выбор, если вы хотите сохранить простоту и просто использовать конфигурацию по умолчанию.
# rpm -qa | grep httpd [Note: If the above command did not return anything, install apache as shown below] # yum install httpd
Убедитесь, что Apache успешно установлен
# rpm -qa | grep -i http httpd-tools-2.2.9-1.fc9.i386 httpd-2.2.9-1.fc9.i386
Включите службу httpd для автоматического запуска при запуске системы с помощью chkconfig. Запустите Apache, как показано ниже.
# chkconfig httpd on # service httpd start Starting httpd: [ OK ]
Если вы выбрали пакет веб-сервера во время установки Linux, Apache уже установлен в вашем Linux. В этом случае вы можете обновить Apache до последней версии, как показано ниже.
Проверьте, установлен ли Apache.
# rpm -qa | grep -i http httpd-tools-2.2.8-3.i386 httpd-2.2.8-3.i386 [Note: This indicates that Apache 2.2.8 version is installed already]
Проверьте, доступна ли последняя версия Apache для установки с использованием yum.
# yum check-update httpd Loaded plugins: refresh-packagekit httpd.i386 2.2.9-1.fc9 updates [Note: This indicates that the latest Apache version 2.2.9 is available for upgrade]

Настройте MySQL для автоматического запуска при запуске системы.
# chkconfig mysqld on
Запустите службу MySQL.
# service mysqld start
В первый раз, когда вы запускаете mysqld, он выдаст дополнительное информационное сообщение с указанием выполнить настройку после установки, как показано ниже.
Initializing MySQL database: 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 dev-db 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 highly 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 mysql-test ; perl mysql-test-run.pl Please report any problems with the /usr/bin/mysqlbug script!

После установки mysql вы можете войти в корневую учетную запись mysql без указания пароля, как показано ниже.
# mysql -u root Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 2 Server version: 5.0.51a Source distribution Type 'help;' or '\h' for help. Type '\c' to clear the buffer. mysql>
Чтобы решить эту проблему, вам нужно назначить пароль для учетной записи root mysql, как показано ниже. Выполните скрипт mysql_secure_installation, который выполняет следующие действия:
# /usr/bin/mysql_secure_installation
Вывод сценария 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): 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: [Note: Enter the mysql root password here] 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!
