AlmaLinux VPS主机

Step 1: Connect via SSH

ssh root@your-server-ip

Step 2: Update the system

dnf upgrade -y

Step 3: Enable EPEL and install common tools

EPEL adds thousands of extra packages built for Enterprise Linux:

dnf install -y epel-release
dnf install -y curl wget git vim nano htop

Step 4: Configure the firewall

systemctl enable --now firewalld
firewall-cmd --permanent --add-service=ssh
firewall-cmd --permanent --add-service=http
firewall-cmd --permanent --add-service=https
firewall-cmd --reload
firewall-cmd --list-all

Step 5: Install a web server (example: Nginx)

dnf install -y nginx
systemctl enable --now nginx
curl -I localhost

SELinux

AlmaLinux runs SELinux in enforcing mode. Keep it on and read the audit log when a service is denied:

sestatus
ausearch -m avc -ts recent

Why AlmaLinux

• RHEL compatible: built to be binary (ABI) compatible with Red Hat Enterprise Linux, so RHEL packages and guides apply.
• Long lifecycle: each major release gets about 10 years of updates (AlmaLinux 9 until 2032, AlmaLinux 10 until 2035).
• Free: no subscription or licence fee.
• Community owned: governed by the non-profit AlmaLinux OS Foundation.
• Upgrade path: the ELevate project upgrades a server in place from one major version to the next.
