As a senior CMS website operation personnel in security, I am very familiar with the importance of database strategy in multi-site management.The design of Anqi CMS fully considers this requirement, providing a flexible and efficient database configuration solution to meet the considerations of data independence and reusability under different operation scenarios.

Database management strategy under AnQiCMS multi-site mode

In the multi-site mode, regarding the database configuration, AnQiCMS adopts a strategy that takes into account both data isolation and management convenience.When you add a new sub-site in AnQiCMS backend, the system will explicitly require you to specify a separate database name for this new site.This means that, even though all sites run on the same AnQiCMS application instance, their website content, user data, configuration information, and other core data will be stored in independent databases for each site.

The importance of database independence and data isolation

It is the default and recommended practice for Safe CMS to configure independent databases for each site under the multi-site mode. This strategy brings multiple advantages:

Firstly,Data isolationIs a core consideration.All data for each site, including articles, products, categories, tags, users, comments, etc., are stored in their dedicated databases.This ensures that the operation of one site does not inadvertently affect the data of another site, effectively avoiding data confusion and potential conflicts.

Secondly,Data SecurityEnhanced.If a site's database is attacked or damaged unexpectedly, the impact is limited to the data of that specific site and will not affect other sites under the management of AnQiCMS.This provides stronger risk resistance for multi-site operations.

Moreover,Performance Optimization and Scalability.When a site experiences a surge in traffic or a large amount of data, it is possible to optimize, back up, or migrate the database of that specific site to an independent database server without worrying about interference with the database operations of other sites.This modular data management method makes it more flexible to expand and maintain individual sites.

Finally,Convenience of Backup and Recovery.Since each site's data is independent, you can create independent backup strategies for each site and perform precise recovery to the site as needed, greatly reducing the complexity of data management and disaster recovery.

Consideration for Database Connection Information Reuse and Independent Configuration

When adding a new site and specifying a new database name, the SafeCMS provides the option of 'Database Information Replication'. Here, the term 'replication' refers to theConnect account and password authentication information, rather than the database instance itself.

If you choose to “Reuse default database account information”, the system will use the AnQiCMS main site (or the one configured during default deployment) database connection credentials (such as database username, password, host address, etc.) to connect to the newly created database. This method is suitable for the following scenarios:

  • Database server unified management:All site databases are deployed on the same database server, and the server allows access to different databases using unified authentication information.
  • Simplified management:Reduced the complexity of creating and managing database users and permissions for each new site, improving deployment efficiency.

However, in some cases, you may need to configure for the new siteIndependent database connection informationThis usually occurs in the following situations:

  • Distributed deployment:The database of the new site needs to be deployed on different database servers, or it needs to use specific database users and permissions that are different from the default site to access.
  • Higher security requirements:To further enhance security, configure independent database users for each site and grant minimal permissions. Even if the connection information of a site is leaked, it is difficult to affect other sites.

The flexibility of AnQi CMS is reflected here, whether you choose to reuse the default connection information or configure it separately for a new site, the system can be compatible and correctly manage the independent database of each site.

Select an appropriate database strategy

When deciding on the specific configuration of the database in the multi-site mode, you need to weigh the following factors:

  • Operation scale and complexity:If your multisite scale is small and all sites are running on the same server, reusing the database connection information can simplify management.
  • Data security level requirements:For sites involving sensitive data or with extremely high security requirements, independently configuring database connection information and implementing strict permission management is a better choice.
  • Technical and management resources:It is more secure to independently configure database users and permissions, but it also increases the complexity of management and maintenance, and it is necessary to consider the technical capabilities and management resources of the team.

In summary, the Anqi CMS provides a powerful multi-site management solution that allows each sub-site to have an independent database and flexible database connection information configuration options, ensuring both data isolation and security while adapting to different operational needs.

Common Questions (FAQ)

1. Can all sites share a database in the multi-site mode of AnQi CMS?

2. What does 'database information reuse' specifically mean? Will the data remain independent after reuse?

“Database information reuse” refers to the option of using the database connection credentials of the AnQiCMS main site when adding a new site, such as the database server address, username, and password.This simplifies the process of connecting to the new database.Even if these connection details are reused, a new, independent database name must still be specified for the new site.Therefore, the data for each site is still completely independent, stored in different database instances, but they use the same "key" to access their respective "safes.

3. If I want to deploy the database of a site to a completely different server, does AnQiCMS support it?

Yes, AnQi CMS fully supports this scenario.When adding a new site, after you fill in the database name, you can choose not to reuse the default database account information.At this time, the system will provide fields for you to enter the independent database host address, port, username, and password.Thus, you can flexibly deploy the database of the new site to any accessible database server, achieving distributed deployment at the database level and a higher level of resource isolation.
