Some basic steps should be taken to help harden the MariaDB Community Server deployment: $ sudo mysql_secure_installation MariaDB Enterprise Server Specific security practices should always follow any business-specific requirements and governance. Start the systemd service for MariaDB Server using systemctl: $ sudo systemctl start rvice After installing the packages, run the mysql_install_db utility to provision this directory. MariaDB Server 10.3 and 10.4 write all data files and tablespaces to a directory on the file system called the data directory. $ sudo yum install -repo="mariadb-main" MariaDB-server Configuring and Securing MariaDB Server To avoid conflict with the OS-vendor packages, install dependencies separately and use the -repo flag to specify the repository: $ sudo yum install perl-DBI libaio libsepol lsof boost-program-options To deploy MariaDB Community Server 10.4 on RHEL 8 or CentOS 8, first download and use the mariadb_repo_setup script to configure the MariaDB repositories for YUM: $ wget Authentication enhancements, including multiple authentication methods per user.Galera 4 technology, a major enhancement over Galera 3.Ability to reload SSL certificates without server restart.Temporal tables, including system-versioned, application time-period, and bitemporal (both).Optimizer trace to aid in performance diagnosis.While CentOS 8 and RHEL 8 include MariaDB Community Server 10.3, substantial enhancements are included in the MariaDB Server 10.4 release series that followed: You can install MariaDB Server from the command-line: $ sudo yum install mariadb-server Benefits of MariaDB Server 10.4 The RHEL 8 and CentOS 8 distributions include MariaDB Community Server 10.3. MariaDB Server is available for use on both RHEL 8 and CentOS 8. CentOS Linux 8 was released in September 2019. The CentOS Project follows releases of upstream RHEL source code with community binary builds a few months later. Red Hat provides a convenient document summarizing the changes from RHEL 7 to RHEL 8, which can be used when planning your upgrade. The latest point release, RHEL 8.1, adds support for kernel live-patching, allowing kernel security fixes to be deployed without reboot.
These include Linux Kernel 4.18 (vs Linux Kernel 3.10), and TLS 1.3 support. RHEL 8 includes a number of important enhancements over its predecessor. Red Hat has announced that RHEL 7.7 will be the last point release on the RHEL 7.x release series, so we expect users will be looking to upgrade before support for RHEL 7.7 concludes in August 2021.
The long-awaited Red Hat Enterprise Linux 8 was released in May 2019. Red Hat Enterprise Linux 7 (RHEL 7) was released back in 2014, and has had seven point releases since. MariaDB Server is available and supported on RHEL 8 and CentOS 8, and is easily deployed from OS vendor repositories or MariaDB repositories using YUM.
