Chapter 15. Infrastructure services


The following chapter contains the most notable changes to infrastructure services between RHEL 8 and RHEL 9.

15.1. Notable changes to infrastructure services

Support for Berkeley DB dynamic back end has been removed

With this release, the Berkeley DB (libdb) dynamic back end is no longer supported. The named-sdb build is no longer provided. You can use the DLZ loadable plugins for each back end, for example, sqlite3 or mysql. Those plugins are not built or shipped and have to be built from the source.

The mod_php module provided with PHP for use with the Apache HTTP Server has been removed

The mod_php module provided with PHP for use with the Apache HTTP Server is no longer available in RHEL 9.

Since RHEL 8, PHP scripts are run using the FastCGI Process Manager (php-fpm) by default. For more information, see Using PHP with the Apache HTTP Server.

The BIND 9.18 is now supported in RHEL

BIND 9.18 has been added in RHEL 9.5 in the new bind9.18 package. The notable feature enhancements include the following:

  • Added support for DNS over TLS (DoT) and DNS over HTTPS (DoH) in the `named`daemon
  • Added support for both incoming and outgoing zone transfers over TLS
  • Improved support for OpenSSL 3.0 interfaces
  • New configuration options for tuning TCP and UDP send and receive buffers
  • Various improvements to the dig utility
