Hello everyone! I’m stuck with a MySQL 8 setup issue on my CentOS 7 system. For certain requirements in my project, I must use CentOS 7 specifically and cannot upgrade to a newer version.
Every attempt to install MySQL 8 results in various errors during the installation process. I’ve tried different approaches but keep running into problems. A colleague mentioned that CentOS 7 might have compatibility issues with MySQL 8, but insisted that it should still be possible to get it working.
Has anyone successfully installed MySQL 8 on CentOS 7? What steps or workarounds did you use? I would really appreciate any guidance or alternative installation methods that might work better. Thanks in advance for any help!
Hit this same problem six months back during a legacy upgrade. MySQL 8 needs OpenSSL 1.1.1 but CentOS 7 only has 1.0.2. I ditched the native install and went with Docker instead - way easier than wrestling with dependencies. You get full MySQL 8 without breaking your system libraries. Just set up persistent volumes for data and map your ports correctly. Performance matches native installs but skips all the RPM dependency hell on CentOS 7. Make sure you’re running a recent Docker version though - older ones had issues with MySQL containers.
Been there! CentOS 7 and MySQL 8 don’t play nice together, but there’s a better approach than fighting with manual installs.
Skip the dependency hell and automate the whole thing. Build a workflow that handles MySQL 8 installation, config, and whatever post-setup stuff you need.
I’ve automated similar database deployments - the script grabs the right packages, sorts dependencies, configures services, even sets up monitoring. Way more reliable than doing it by hand, especially when you’re repeating the process.
Bonus: you can version control everything. Something breaks? Roll back or iterate fast instead of trying to remember which manual steps worked.
Latenode’s great for this kind of deployment automation - handles complex installation workflows perfectly: https://latenode.com
Your colleague’s right - MySQL 8 works on CentOS 7, but you’ll need extra steps. The problem is MySQL 8 needs newer system libraries than CentOS 7 comes with. I hit the same issue last year during a production migration. Skip the repository install and grab the MySQL 8.0 RPM bundle straight from Oracle’s site instead. Install the packages in order and update system dependencies first. Here’s what tripped me up: make sure the secure installation script runs correctly after setup. MySQL 8’s authentication is stricter and will break connections if you don’t configure it right during initial setup. Also check your system resources - MySQL 8 needs more memory than older versions. It’ll fail silently on startup if your system’s too constrained.
hey omarR_85! i totally understand, MySQL 8 on CentOS 7 can be a pain. try looking into the community repo for the install files, and don’t forget to disable MariaDB—they can clash hard. took me a bit to figure it out but it works!
