The self-hosted CMS on the selection list requires PHP 8.4 to start, how to check each environmental dependency item by item?

📅 2026-11-01 👁️ 0

When the operation requirements are written in the selection list, break it down into four columns for item-by-item verification: language runtime, framework version, database, optional extensions. A system starting with PHP 8.4 means that the host needs to move PHP version, which is a mandatory item; optional items should be marked separately to avoid discovering that the extension is not installed during deployment. The verification table should be completed before purchasing the host, rather than补环境 after going online.

Why do we need to split the running requirements into four columns

The format in the third-party self-hosted list can be used as a sample: There are systems that label themselves as a combination of Laravel and React, requiring PHP 8.4 or above; Strapi, Directus, Ghost and other Node.js runtime systems, with Ghost additionally requiring MySQL 8, and Payload being a TypeScript project. These entries read as 'requirements' when mixed on a single line, but splitting them into four columns can reveal the workload:

  • Runtime language: Determines what the host installs and also determines who will do the subsequent upgrades.
  • Framework version: Determines compatibility range, major version upgrades often come with expansion and theme adaptation windows.
  • Database: Determines instance specifications and backup strategies, the version lower limit affects whether the existing libraries can be reused.
  • Optional extensions: Determine feature switches, missing extensions usually report errors during runtime.

The value of splitting columns lies in distinguishing between 'must satisfy now' and 'affected by upgrades later', many selection disputes actually arise from the confusion between the two.

Runtime major version affects the upgrade window

This requirement for starting with PHP 8.4 and similar conditions, on the surface, is just a version number, but it actually affects the rhythm: if the existing host is a lower version, either upgrade the runtime first and then install the system, or run two versions in parallel on the same machine for migration; both paths require time for regression testing. Upgrading to a major version of the runtime will also affect extension compatibility, making it more reasonable to do this before content migration, to avoid changing two layers at the same time.

The deployment logic of the GoLang series is different. Taking the technical stack of GoLang with Iris framework and GORM as the data layer as an example, the output is a single executable file, the host side does not require a resident language runtime, and dependencies are converged in the binary and database connections. As a result, the verification items are concentrated elsewhere: process guard mode, default listening port, and reverse proxy rules.

The corresponding relationship between database and host configuration

The database dependency directly affects the specifications and backup scope of the host. When only listing

Checklist before purchasing a host

Check items The content that needs to be written clearly Consequences when not met
Language runtime Version minimum, whether resident, who upgrades Cannot be installed or must migrate in parallel version
Framework version Main version compatibility range, extension requirements Function interruption during major version upgrade
Database Type, version lower limit, character set Unable to reuse existing instances or require data conversion
Optional extension List mandatory and optional columns Runtime error, high troubleshooting cost
Port and proxy Default port, reverse proxy rules For example, the 8001 port not forwarded causes external access to be unavailable
Backup and restore Does it contain static files, and can it be recovered independently There is no available rollback point when an issue occurs
Deployment method One-click deployment panel, Docker image, or manual The rollback time does not match the operation and maintenance habits

When filling out this form, do three things in order: first, confirm the mandatory items on the checklist, then install it once on the test machine to record missing dependencies, and finally write the person responsible for ports, backups, and upgrades into the operation and maintenance records.

Common questions

Question: If the checklist only writes running requirements and does not write optional extensions, how to make up for it?Answer: The installation result of the test machine should be taken as the standard. The missing items reported during the first deployment are the actual list of optional extensions. Write them down one by one, and prepare the same record for the formal environment.

Question: When the host is running an old version, should an upgrade be performed specifically for the selection?Answer: First, look at the impact of the upgrade. Migrating to a new version in parallel on the same host is usually safer than performing a local major version upgrade, and then recover the old environment after the switch is completed.

Question: How much difference in cost between the Go system and the PHP system on the host?Answer: The difference lies mainly in the resident overhead and concurrent carrying capacity, not in whether it can run. It is more reliable to determine the position by measuring the resident memory with the same load aperture than to make a budget judgment based on language.

The official migration list lists the theme styles as items that cannot be taken away. Should the template be redone?

The migration list puts the theme style as an item that cannot be taken away, which does not mean that the template must be rewritten from scratch. The judgment sequence is to first list the content and fields that can be taken away, and then estimate the working hours according to the number of page types, field structure, and special components: the text and media go through batch import, the field structure is supported by the content model, and the style layer is remade according to the template rules of the new system. Before making changes, make a backup of the template and static files, keep a rollback point, and then preview each page with a draft to check.

Should the visibility of AI search be reviewed regularly, and how often should it run one round?

The AI search visibility is worth regular review, the rhythm usually consists of two layers: monthly running a round of reference checks, looking at whether the official website is cited and whether the口径 is distorted in the same set of questions; quarterly review to see if important content needs to be rewritten or supplemented with data. When implementing, the question list should be fixed, covering brand words, comparative words, and scenario words, and the same batch of engines should be used in the same round, otherwise the data is not comparable. The keywords library, drafts, and pending release status on the site determine whether the review conclusion can smoothly fall into the schedule.

The release schedule of open-source projects is predictable, the Drupal official schedule has clearly stated that the next major version is scheduled for the week of December 2026, and also listed the end of security support for some branches. The site should reserve an upgrade window in advance, rather than dealing with it on the day of the announcement: first, divide the scheduling into major versions, minor versions, and security fixes, and then prepare reversible backups, independent pre-release environments, and content freeze periods before the window, and write the version tracking into the annual maintenance schedule.

Open-source website building tools have written order callback and login modification into the new version, can the corporate website use it?

The open-source website building tool incorporates order callback, registration login modification, and AI expansion into the new version, which may not be necessary for corporate websites. The criteria for judgment are data ownership and whether additional services need to be resident: orders and finance belong to business system integration, login and group permissions directly affect the back-end security boundary, and editor and template updates are the parts that the content team feels strongly about in daily life. Do not hang externally if it can be covered by built-in modules, and confirm the interface scope first if external system cooperation is needed.

The announcement writes the authentication bypass and marks it as 9.8 points, should we stop this kind of temporary login function first?

Seeing the bypass of authentication with a high-risk score, it is not necessary to immediately shut down all at once, but it is necessary to first judge whether it is in use, whether it is accessible from the outside, and whether there is an alternative path. The attack surface of temporary login functions is in three points: who can apply, how long the validity period is, and whether it is protected by secondary verification. The disposal sequence is to collect the exposed range, concentrate on credential rotation, supplement session invalidation and log verification, and then decide on patches or shutdown, while confirming that the back-end authentication entry has anti-automation protection.
