Slide 1 : LINUX KOLLA SANJEEVA RAO MCA

: LINUX INSTALLATION

Naming Conventions for Physical Devices : Naming Conventions for Physical Devices Hard Disk: hd Primary master : /dev/hda Primary slave : /dev/hdb Secondary master : /dev/hdc Secondary slave : /dev/hdd

Naming Conventions for Physical Devices : Naming Conventions for Physical Devices SATA Hard Disk: /dev/sda /dev/sdb /dev/sdc /dev/sdd Here there is no concept of Primary & Secondary or master & Slave.

Naming Conventions for Physical Devices : Naming Conventions for Physical Devices SCSI Drive:/dev/sda The main aim of SCSI is that several peripherals can be daisy chained to one host adapter, using only one slot in the bus. Here there is no concept of Primary & Secondary or master & Slave.

Naming Conventions for Physical Devices : There is no drive letters in LINUX such as C in Windows, here the convention is /dev/hda1. Naming Conventions for Physical Devices Partitions

Naming Conventions for Physical Devices : Floppy: fd /dev/fdo ( For Floppy-1) /dev/fd1 ( For Floppy-2) Naming Conventions for Physical Devices

Naming Conventions for Physical Devices : Naming Conventions for Physical Devices TAPE DRIVE: ht /dev/ht0 (for Tpae drive 1) /dev/ht1 (for tape drive 2)

Naming Conventions for Physical Devices : Naming Conventions for Physical Devices cdroms: /dev/cdrom 0 (for CDROM- 1) /dev/cdrom 1 (for CDROM- 2)

Naming Conventions for Physical Devices : Naming Conventions for Physical Devices pen drives: /dev/sda1 (for all external devices )

TYPES OF INSTALLATION : TYPES OF INSTALLATION

MODES OF INSTALLATION : MODES OF INSTALLATION LINUX TEXT LINUX No probe Linux Media Check Linux Rescue Linux updates Linux Ask method

REQUIREMENTS OF INSTALLATION : REQUIREMENTS OF INSTALLATION

STEP BY STEP PROCEDURE FOR TEXT BASED INSTALLATION : STEP BY STEP PROCEDURE FOR TEXT BASED INSTALLATION Before putting the REDHAT linux CD-01 put the computer in BOOT from CD-ROM mode from BIOS setup. Insert CD and Select /press F2 to get the modes of installation, such as LINUX TEXT LINUX No probe Linux Media Check Linux Rescue Linux updates Linux Ask method For graphical mode press ENTER for text mode you have to type at boot: linux text Select New installation or Re Installation

STEP BY STEP PROCEDURE FOR TEXT BASED INSTALLATION ( contd..) : STEP BY STEP PROCEDURE FOR TEXT BASED INSTALLATION ( contd..) Select Automatic partition or Manual partition [ with DISK DRUID] DISK DRUID is a partition tool. Delete all existing partitions ( use up and down arrows for giving option to get ‘*’ on appropriate selection use space bar to get ‘*’ and follow instructions given at the bottom such as F4 for delete and so on) (a) Allocate the sizes to mandatory directories. (b) Create SWAP Area

STEP BY STEP PROCEDURE FOR TEXT BASED INSTALLATION ( contd..) : STEP BY STEP PROCEDURE FOR TEXT BASED INSTALLATION ( contd..) Example: How to create a new partition? Mount point: / File System Type: Ext3 Allowable on :hda ( in case if your HDD is connected to primary master) size :4000MB one partition is created . ( Repeat this procedure to create all partitions)

STEP BY STEP PROCEDURE FOR TEXT BASED INSTALLATION ( contd..) : STEP BY STEP PROCEDURE FOR TEXT BASED INSTALLATION ( contd..) How to create swap area ? Mount point : [ ] nothing to be selected File System Type : SWAP Allowable on : hda ( in case if your HDD is connected to primary master) size : Double of the RAM Size if RAM<1 GB) 1 ½ of RAM size if RAM<1 GB Note: To find out the RAM size press Ctrl+Alt+F2 and type command FREE and to come back to Text mode press Ctrl+Alt+F1 and to come back to GUI mode press Ctrl+Alt+F7.

HOW SWAP PARTITION WORKS? : HOW SWAP PARTITION WORKS?

STEP BY STEP PROCEDURE FOR TEXT BASED INSTALLATION ( contd..) : STEP BY STEP PROCEDURE FOR TEXT BASED INSTALLATION ( contd..) 7. Select Automatic partition. or Manual partition [ with DISK DRUID] DISK DRUID is a partition tool. Format all Partitions. The file system is Ext 3. We can choose boot loader label and we can edit the label. Configure Network address, Firewall option etc. Give the Root password. Select and customize software packages. After installing all CDs it will ask for again Ist CD , insert it and wait for completion of Installation. Reboot the system. User name: ROOT ( default user made by the System) Password: Welcome to REDHATLINUX V4. ********

STEP BY STEP PROCEDURE FOR GUI BASED INSTALLATION : STEP BY STEP PROCEDURE FOR GUI BASED INSTALLATION Boot up system using CD. Press Enter at the boot prompt. Choose the appropriate language( English). Press Enter on the OK prompt. Choose the Appropriate Key Board (US). Press Enter on the OK prompt. Configure TCP/IP. Select Use Dynamic IP configuration ( BOOTP/DHCP). Press Enter on the OK prompt. Pres Enter on the OK prompt. At this point Anaconda ( the installer ) will retrieve the necessary installation image and will probe the system for its monitor and mouse type and will finally present you with the welcome screen. Click Next. Choose the appropriate mouse for your system . Click Next. Manually partition your system using Disk Druid( Delete any Pre Existing partitions). The partitioning Scheme is as follows:

STEP BY STEP PROCEDURE FOR GUI BASED INSTALLATION ( contd..) : STEP BY STEP PROCEDURE FOR GUI BASED INSTALLATION ( contd..) Format all partitions. Use the Default Boot Loader Settings. Choose DHCP for networking and activate on boot. Choose Enable Firewall. Select the appropriate language Support. Set the time Zone as appropriate for location. Set the root password. Select the Customize the set of packages to be installed and click next. You should be now be at the about to install screen. Click next to begin. Reboot the system after installation. Welcome to REDHATLINUX V4. ********

PROCEDURE FOR NET WORK BASED INSTALLATION : PROCEDURE FOR NET WORK BASED INSTALLATION Just Follow the Above Steps up to Configuring TCP/IP NFS METHOD: NFS Server name : 188.152.0.253 ( For Example) NFS mount : /var/ftp/pub FTP METHOD: FTP Site name : 192.168.1.254 ( For Example) REDHAT Diretory : pub/… Again just follow the Normal Method. Here system will pick up the image from Server instead of CD.

Sample Partition Structure : Sample Partition Structure

Partitioning HARD DRIVES : Partitioning HARD DRIVES Hard Drives are divided in to partitions . Partitions normally contain file systems. . Primary . Extended . Logical The default file system in Linux is EXT3. Multiple partitions may be assembled in to larger virtual partition: software RAID and LVM. Primary: The first four partitions on the disk are called primary partitions. Extended: If more than four partitions are needed , one of the four partitions may be converted into a special extension partition. Logical: Extension partition that may contain one or more logical partitions.

MBR ( MASTER BOOT RECORD) : MBR ( MASTER BOOT RECORD) It contains Boot Loader Partition table Boot signature Boot loader: It gives GRUB loader information. Partition table: It gives information about partition such as starting address, Ending address , size etc. Boot Signature: It is having active partition information.

RAID &LVM : RAID &LVM Multiple partitions may be assembled in to a single virtual partition by using Advanced techniques. Software RAID: It is used to provide redundancy, improve performance, or create partitions bigger than a single disk. multiple partitions from different disks are assembled in to a RAID Device, A disk drive which is treated like a normal partition. LVM: LVM is used to assign one or more partitions to a volume group, which can be used to create virtual partitions called logical volumes. These logical volumes are easier to resize than normal prtitions.
