Выбрать версию PHP под определенную CMS и не плакать
“Я же сказал — полетели, а не побежали!”
“Давай, страус, пошел! Работаем, работаем!”
PHP сейчас один из самых популярных языков программирования, используемых для создания сайтов. На shared linux веб хостинге в России с выбором версии PHP не совсем гладко, хотя встречаются исключения из этого правила.
Почему выбор версии необходим? Интересно? Добро пожаловать под кат!
Рассмотрим системные требования самых распостраненных CMS на рынке России — WordPress, Bitrix, Drupal и Joomla к версиям PHP (про модули говорить не будем, это тема для отдельной статьи):
-
8: PHP 5.5.9 or higher : PHP 5.3 or higher 3.4.7: PHP 5.5 or higher 4.4: PHP 5.2.4 or higher
-
:
- 6 – PHP 5.3
- 7 – PHP 5.4
- 7 – PHP 5.4
- 8 – PHP 5.6
- 13 – PHP 5.4
- 14 – PHP 5.5
- Постоянно пересобирать пакеты из исходников?
- Зависеть от сторонних репозиториев (людей)?
- Следить за баг трэками для оперативного внесения заплаток?
- Держать несколько VPS или dedicated серверов с разной версией PHP для различных WEB проектов (а ещё и для разработки)?
- Уменьшение трудозатрат, как на развертывание, так и на сопровождение проектов.
- Возможность выбрать версию PHP не обращаясь к техподдержке. Переключение версий происходит меньше чем за минуту!
- Бэкап и доступ к консоли или каталогам по безопасному протоколу SSH. Также и проверенным способом – протоколом FTP.
- Катастрофоустойчивость – возможность быстрого развертывания инфраструктуры в другом ЦОД`е.
- Создать собственный репозиторий и систему обновлений для него. Что стоило для нас появлением у сотрудников красных глаз. Сборки PHP (5.2 — 5.6) мы собирали со своими параметрами, для того чтобы установить и использовать их параллельно в одной системе.
- Создать на портале самообслуживания страницы управления.
- Внедрить обученного агента в CloudLinux для биллинга и управления услугами из ЛК. На момент разработки агента в CloudLinux еще небыло такого функционала как PHP Selector, поэтому данную функцию выполняет сам агент.
- 2-Years Active Support: the support includes fixing BOTH BUGS and SECURITY ISSUES.
- 1-Year Security Support: the support includes fixing ONLY CRITICAL SECURITY ISSUES.
PHP Version 7.4– No Longer Supported- PHP Version 8.0(Security Support, ends on 26/11/2023)
- PHP Version 8.1(Active Support, ends on 25/11/2023)
- PHP Version 8.2(Active Support, ends on 08/12/2024)
- Log in to your WP Admin Dashboard .
- Navigate to the sidebar menu and choose: Tools then Site Health .
- From the opened interface, choose Info tab.
- From the list displayed, navigate to Server section and click on the small arrow to expand it.
- Here you will find your PHP version as well as other server details.
У себя мы используем CloudLinux, который по пакетной базе соответствует CentOS 6.7. Ситуация “из коробки” не радужная – версии PHP весьма старые.
А те клиенты, у которых сайт создан давно и CMS не обновлялась (а таких немало приходит к нам с других хостингов) как правило хотят ровно обратного — более старых версий PHP из-за того, что на их CMS имеются проблемы с совместимостью.
Так что выходов два: либо собирать самому из исходников, либо ставить из сторонних репозиториев, что не всегда возможно.
Немного остановлюсь на агенте, который взаимодействует между ЛК и системой где развернут хостинг. Агент (написан на питоне) представляет из себя службу с документированным api, позволяющую взаимодействовать с CloudLinux`ом. в качестве оркестратора. Касаемо PHP — агент позволяет изменить версию и настройки для определенного клиента. При создании новой услуги (пользователя) агент использует предустановленные настройки, которые позже можно сменить на кастомные.

Supported Versions
Each release branch of PHP is fully supported for two years from its initial stable release. During this period, bugs and security issues that have been reported are fixed and are released in regular point releases.
After this two year period of active support, each branch is then supported for an additional year for critical security issues only. Releases during this period are made on an as-needed basis: there may be multiple point releases, or none, depending on the number of reports.
Once the three years of support are completed, the branch reaches its end of life and is no longer supported. A table of end of life branches is available.
Какую версию PHP выбрать для сайта?
На первый взгляд ответ простой — последнюю.))) Я тоже так считаю, но когда я скачивал PHP 5.3 (5.3.8) VC9 для Windows, то увидел следующую информацию:
**Какую версию выбрать?
-Если вы используете PHP с Apache 1 или Apache2 от apache.org вам нужно использовать VC6 версий PHP
-Если вы используете PHP с IIS вы должны использовать VC9 версий PHP
-VC6 Версии составляются с наследием Visual Studio 6 компилятор
-VC9 Версии составляются с Visual Studio 2008 компилятор и есть улучшения в производительности и стабильности. VC9 версии требутся установить Microsoft 2008 C + + Runtime (x86) или Microsoft 2008 C + + Runtime (x64)
-Не использовать VC9 версию с apache.org файлами.
-VC9 версии Apache могут быть выбраны в Apache Lounge. Мы используем их для создания бинарных файлов Apache видами SAPI.**
На моем хостинге сейчас подключен сервер Apache 1.3.* [s56, Windows 2008 R2], aux3
Есть вариант перевести на Linux 2.6 с модулями Apache 1.3.*, Fast CGI, CGI
