Как установить PHP 7.2 на RHEL 8 / CentOS 8
Как я могу установить MariaDB 10.4 на компьютере с ОС CentOS 8 / RHEL 8 Linux? MariaDB — это многопользовательский многопоточный сервер баз данных SQL, разветвленный от системы управления реляционными базами данных MySQL. Он был разработан, чтобы быть быстрым, надежным и с более продвинутыми функциями, подходящими для агрессивных операций с базами данных.
Мы не будем обсуждать интересные функции системы баз данных MariaDB 10.4, вы можете проверить примечания к выпуску для подробного описания набора функций . Вот только простые шаги, необходимые для работы работающего сервера базы данных MariaDB 10.4 на компьютере с ОС CentOS 8 / RHEL 8 Linux.
Установите MariaDB 10.4 на CentOS 8 / RHEL 8
Это идеальные шаги, которые вы пройдете при установке MariaDB 10.4 на сервере CentOS 8 / RHEL 8 Linux.
Шаг 1: Обновление системы
Если у вас нет критически важных служб, работающих в Production на сервере, обновите систему перед началом установки MariaDB 10.4 на CentOS 8 / RHEL 8.
sudo dnf -y upgrade
Шаг 2: Добавьте репозиторий MariaDB 10.4 в CentOS 8 / RHEL 8
Теперь нам нужно добавить репозиторий MariaDB yum для нашей архитектуры ЦП. В этом руководстве будет описано добавление репозитория для компьютера с процессором x86_64.
CentOS 8:
sudo tee /etc/yum.repos.d/MariaDB.repo<<EOF
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.4/centos8-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
EOF
RHEL 8:
sudo tee /etc/yum.repos.d/MariaDB.repo<<EOF
[mariadb]
name = MariaDB
baseurl = http://yum.mariadb.org/10.4/rhel8-amd64
gpgkey=https://yum.mariadb.org/RPM-GPG-KEY-MariaDB
gpgcheck=1
EOF
Шаг 3: Установите репозиторий MariaDB 10.4 в CentOS 8 / RHEL 8
После добавления репозитория Yum вы можете сразу же приступить к установке репозитория MariaDB 10.4 в CentOS 8 / RHEL 8.
CentOS 8:
sudo dnf install boost-program-options
sudo dnf install MariaDB-server MariaDB-client --disablerepo=AppStream
sudo systemctl enable --now mariadb
RHEL 8:
sudo dnf install boost-program-options
sudo dnf install MariaDB-server MariaDB-client --disablerepo=rhel-8-for-x86_64-appstream-rpms
sudo systemctl enable --now mariadb

Шаг 4: Безопасный сервер базы данных MariaDB
Теперь, когда MariaDB 10.4 установлен на CentOS 8 / RHEL 8, защитите его, запустив mysql_secure_installation.
$ sudo mysql_secure_installation NOTE: RUNNING ALL PARTS OF THIS SCRIPT IS RECOMMENDED FOR ALL MariaDB SERVERS IN PRODUCTION USE! PLEASE READ EACH STEP CAREFULLY! In order to log into MariaDB to secure it, we'll need the current password for the root user. If you've just installed MariaDB, 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 MariaDB root user without the proper authorisation. Set root password? [Y/n] y New password: Re-enter new password: Password updated successfully! Reloading privilege tables.. ... Success! By default, a MariaDB installation has an anonymous user, allowing anyone to log into MariaDB 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, MariaDB 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 MariaDB installation should now be secure. Thanks for using MariaDB!
