At this moment CentOS 9 is only available as stream. So we need to find something else.
The co-founder of CentOS has started a new distro that we can use instead of CentOS. This is Rocky linux. This is also based on RedHet linux.
Steps
If you don't have a GUA for IPv6 you can forget it or use a fe80::/64 or fd00::/64 address.
If you want only a IPv4 server, ignore the IPv6 settings.
- Download your installation distro and burn it on a USB-stick. You can use the minimal version whitch is for servers. Additional packages are downloaded when you install it. You can find the latest Rocky linux 9.4 for x86_64 on the download pages.
- Read the release notes.
- Read the documents.
- If you use multiple harddisks make a partitionplan.
- The machine must boot from USB-drive as first choice and HDD as second. Check your BIOS setup.
- Connect the USB to your machine and reboot.
- Follow the instructions. You can setup the network for IPv4 and IPv6 with fixed IP addresses.
- Reboot the system after install, login as root and run yum -y update.
- Configure the system.
- Check if the networkcard is started at bootup. See /etc/sysconfig/network-scripts/ifcfg-xxx and /etc/sysconfig/network-scripts/ifcfg-lo files for ONBOOT="yes"
- Check and config the firewall for IPv4 and IPv6. At this point only the SSH-port should be open.
- Ping the server by its IPv4 and IPv6 address on a external host.
- Ping on the server the gate by its IPv4 and IPv6 addresses.
- Test with a ssh on a external host if you can connect to ssh by IPv4 and IPv6.
- Only when the above works you can proceed with the rest. You can install the rest of the deamons and do maintanance via a SSH-terminal.
