###RedHat Objectives###
----------------------------------------------------------
. Boot, reboot, and shutdown the system normally
. Diagnose and correct problems at boot
. Boot systems into different runlevels for troubleshooting and system maintenance
. Use single-user mode to gain access to a system for which the root password is not known
. Diagnose and correct misconfigured networking settings
. Diagnose and correct hostname resolution problems
. Diagnose and address permissions problems and SELinux policy violations
. Diagnose and correct non-hardware disk storage problems
. Adding new partitions, logical volumes, filesystems, and swap areas to a system non-
destructively
. Manually open, mount, unmount, and close LUKS-encrypted filesystems
. Extend existing unencrypted ext4-formatted logical volumes
. Login or switch user to the root account
. Use ssh and VNC to access remote systems
. Locate and read on-line documentation using man, info, and files in /usr/share/doc
. Locate and analyze system log files
. Understand how to use grep and regular expressions to analyze text output
. Access a bash shell prompt and issue commands with correct syntax; use pipelines and I/O
redirection
. Use text editors such as gedit and vim to create and edit text files
. Manage system resources: identify CPU/memory intensive processes, adjust process priority
with renice, kill processes
. Manage files and directories: create/delete/copy/move; create hard and soft links
. Use tar, gzip, and bzip2 to archive and compress files
. Install Red Hat Enterprise Linux manually with the graphical installer from network installation
media
. Install Red Hat Enterprise Linux automatically using Kickstart
. Configure a physical machine as a RHEL-based virtualization host
. Manage virtual machines: install/start/stop/configure to start at boot/access a VM ́s graphical
console
. Manage disk partitions: understand MBR-style partitions (primary,extended,logical);
list/create/delete partitions
. Manage logical volumes: create/remove physical volumes, assign PVs to volume groups,
create/delete logical volumes
. Create and configure LUKS-encrypted partitions and logical volumes to prompt for password and
mount decrypted filesystem at boot
. Canage ext4 filesystems: create, label, mount, mount automatically at boot (by UUID or label),
unmount
. Mount and unmount CIFS and NFS network filesystems, manually or by configuring autofs
. Manage network devices: understand basic IP networking/routing, configure IP
addresses/default route statically or dynamically
. Manage name resolution: set local hostname, configure /etc/hosts, configure to use existing
DNS server
. Manage network services: check status, start, stop, configure to start automatically at boot
. Configure the scheduling of tasks using cron and at
. Manage local user and group accounts: create, delete, change passwords, adjust password
aging, adjust group memberships
. Use network user and group accounts stored on an existing LDAP directory service
. Manage standard permissions: list, interpret, change ugo/rwx
. Use sgid directories for collaboration
. Set and manage Access Control Lists (ACLs)
. Manage SELinux security: set enforcing/permissive modes, list file and process context, restore
default file context, use "booleans" to adjust policy
. Manage default firewall settings with basic tools
. Install and update software packages from RHN or remote repository, or from the local
filesystem
. Update the kernel package appropriately to ensure a bootable system
. Modify the system bootloader
. Configure the system to synchronize system time using remote NTP servers
. Deploy a VNC server that allows multiple desktops to be shared
. Deploy file sharing services with HTTP/FTP
