Install RHEL or CentOS 5: Archived Manual Installation Guide

Archived RHEL/CentOS 5 installation guide. Original English figures are retained, edited bitmap labels are English instructional illustrations, and official English replacement figures state their differing example settings in captions. These are documentation examples, not a newly executed or verified installation on a current server. No OS, disk, firewall or account operation was performed while preparing this guide.

Red Hat/CentOS 5.x System Installation Steps

1. Boot from CD-ROM and Load RAID Card Driver

Use a trusted installation medium and any required driver-update disk matched to the actual controller, OS/kernel and architecture. The source demonstrates a Legacy optical-drive boot, not a universal no-UEFI rule for every platform. Select the intended supported firmware mode and installation device rather than changing an existing installation blindly.

The archived example enters linux dd at the installer boot: prompt to request a driver disk. A driver update is required only when the supported hardware needs it; first verify controller/logical-drive visibility and compatibility. Match the driver to the actual image rather than copying a generic filename or device number.

A prompt will appear to load the RAID card driver; select Yes.

Reading driver disk

After loading the drivers, you will be prompted whether to load additional drivers; select NO.

The system will prompt to verify the CD media. You may choose to skip or verify based on your situation. Select SKIP and press Enter.

 

2. Basic Settings

Enter the main installation interface and click Next.

Select Language

Select Keyboard; keep the default setting.

Official RHEL 5 English Keyboard Configuration: U.S. English is selected, as in the OEM example; the scrolled list shows a different range of available layouts.

3. Disk Partitioning Setup

Choose to create a custom partition structure and configure partitions according to your needs.

Official RHEL 5 partition-method menu includes Create custom layout. Its underlying example uses an hda 5114 MB virtual IDE disk and a removal/default-layout method; select Create custom layout for this procedure. The OEM source already selects custom layout on an 8189 MB VMware sda. Verify the target; removal and formatting can destroy existing data.

Plan the actual supported boot and application partition layout. Root and swap alone are not a universal recipe for every firmware mode or storage arrangement. Partition deletion and formatting can destroy existing data; verify the target and protect required data before proceeding.

For swap, select swap as the filesystem type with no ordinary filesystem mount point. The OEM form shows 600 MB and the later rounded disk layout shows swap 596 MB. Size it for actual RAM, workload and OS requirements; the source’s 1.5–2 times RAM rule and 32/64 GB examples are not universal requirements. The official replacement illustrates the generic Add Partition fields with ext3/100 MB defaults, not a completed swap configuration.

Official RHEL 5 Add Partition dialog illustrates the same fields, but starts with ext3, a blank mount point, fixed 100 MB on vda 8189 MB and primary unchecked. For the OEM swap example choose swap with no filesystem mount point and the intended capacity; the OEM form shows 600 MB. The official picture is not a completed swap selection.

Create the root partition (/) as shown in the figure below. Select '/' as the mount point, choose 'ext3' as the file system type, and set the size according to actual needs or use all available space.

The same official Add Partition form illustrates root partition fields: set Mount Point / and the intended ext3 capacity or fill policy. Its blank mount point and fixed 100 MB are defaults, not a ready root layout. The OEM root form instead selects fill all available space on sda; verify the actual supported boot layout.

Below is an example of created disk partitions. Click Next to continue.

Official RHEL 5 Disk Druid overview shows an alternative LVM layout on a 152586 MB ATA disk: VolGroup00 152448 MB, / ext3 150464 MB and swap 1984 MB. The OEM example instead shows standard partitions on an 8189 MB VMware disk: / ext3 7585 MB, swap 596 MB and 8 MB free. These are different examples, not fixed sizing rules or one continuous installation.

Select the installation location for the GRUB bootloader. Default is /dev/sda.

Important! If installing the system via USB, /dev/sda might not be the local disk. Check 'Configure Advanced Boot Loader Options' and ensure the local disk is adjusted to the first position to avoid installing GRUB on the USB drive, which would prevent the system from booting.

Official RHEL 5 bootloader screen targets /dev/hda with OS /dev/VolGroup00/LogVol00 and advanced options checked. The OEM screen targets /dev/sda with OS /dev/sda1 and advanced options unchecked. Identify the actual local boot disk; a USB installer may change enumeration.

4. Network Settings

Configure the actual network plan. The OEM picture shows a static 192.168.0.229/24 network and manual hostname while the prose recommends DHCP; the official replacement shows a separate DHCP example. DHCP requires a working link and reachable service. Do not copy the pictured addresses or assume networking will work without configuration.

Official RHEL 5 network example uses eth0 DHCP for IPv4/IPv6 and automatic hostname. The OEM source instead shows IPv4 192.168.0.229/24, IPv6 disabled, localhost.localdomain, gateway 192.168.0.251 and DNS 192.168.0.111 plus 202.102.224.68. These are alternative configurations; enter only network-assigned values.

Set the time zone to Asia/Shanghai.

Set Root Password

Official RHEL 5 root-password form shows masked input. The OEM example illustrates the same fields; neither supplies a reusable secret. Set an appropriate password locally.

5. Package Selection

Select the packages to install. Check 'Customize Now' and click Next.

Official RHEL 5 Package Group Selection has Customize now selected and Software Development/Web server unchecked. The OEM medium lists additional task choices including virtualization. Choose required packages for the actual medium and workload.

Please check boxes according to your actual needs.

Select only package groups and development prerequisites required for the intended workload or a particular source-built driver. Installing every Development Tools optional package is not mandatory for all systems, and supported precompiled drivers have different requirements. The original package-detail screen shows Office/Productivity, not proof of all development packages being selected.

Official RHEL 5 Package Group Details illustrates optional-package selection under Base System/Administration Tools, with 13 of 14 optional packages selected. The OEM picture instead shows Applications/Office-Productivity with 1 of 2 selected. These are different selected groups, not proof that all Development Tools or every optional package was installed.

Installation in progress; please wait for completion.

After installation, the machine needs to be restarted. Click the Reboot button; upon reboot, boot the system from the hard disk.

6. Post-Installation Settings

Boot the system to the welcome screen. Next, perform some basic configurations by clicking the Forward button.

Read the applicable license and accept only if the responsible user agrees. The translated historical bitmap illustrates the agreement controls and visible source text; consult the actual agreement supplied with the installation medium. No agreement was accepted while preparing this guide.

Configure the firewall for only the services required by the actual workload. The source prose recommends disabling it, but its picture shows Enabled, with FTP, SSH, Samba and WWW (HTTP) checked, NFS4 and Telnet unchecked. Blanket disabling is not a general installation requirement; the picture’s service choices are historical examples, not a policy to copy.

Keep an appropriate SELinux policy for the actual system. The source prose recommends disabling SELinux, but the pictured value is Enforcing and the interface recommends keeping the default. Do not disable it merely to complete this generic installation procedure.

Configure kdump with sufficient reserved memory, a suitable dump destination and verification if crash capture is required. The supplied screenshot actually has Enable kdump unchecked, 462 MB total, 0 MB reserved and 462 MB usable. It does not demonstrate working crash collection.

Set date and time

Configure updates/registration according to the actual entitlement and update plan. The OEM prose chooses registration later, while its screenshot selects Yes, register now. These are different choices; the archived screen does not establish current RHN availability. The source’s suggested alternative label is

Create an appropriate non-root account for ordinary work. Although this historical Setup Agent permits skipping the page, that does not make routine root sessions a recommended default.

No need to configure the sound card. Click the Forward button to continue.

Do not install from the attached CD. Click the Finish button.

The source ends at the login screen with root typed as its example username. Log in using the intended non-root account for ordinary work and verify the actual installation and network; the example is not a recommendation for routine privileged use.

 

English reference and source scope

Red Hat Enterprise Linux 5 Installation Guide supplies English terminology and installer illustrations. Its different disk layouts, boot devices, package groups and network selections are identified beside the replacement images; they do not certify an OEM hardware/driver combination. Historical calendar/time values and the senyablog source attribution remain as source data. Language autonyms in language lists are preserved. The manufacturer’s EULA index is an additional reference; the actual agreement accompanying the chosen medium governs its acceptance.
