I will do linux server administration on redhat centos and debian

Need a reliable hand managing your Linux server? As a Linux trainer who teaches the complete RHCSA and RHCE course, I set up, fix and maintain Red Hat, CentOS and Debian systems. I can help with: - Initial server setup and SSH configuration (key-based login) - User, group, sudo and file permission management - Package installation and updates (dnf/yum, apt) - Service management with systemd (Apache httpd, SSH, cron) - Disk, partition, LVM and mount configuration - firewalld, SELinux basics and log checks - Bash scripts to automate backups and routine tasks - Linux troubleshooting: boot, service, permission and network errors Every job includes the commands used and a short summary, so you know exactly what changed on your system. Please message me with your distribution, version and task before ordering. I will review it and confirm the scope, so the work stays safe and on time.
