CentOS System installation Configuration graphics and text tutorial

Description

In the actual production environment, the CentOS 5.x series is still the preferred system for many server builders

As of the current CentOS 5.x latest version of CentOS 5.10, the following describes the CentOS 5.10 of the specific installation configuration process

Server-related settings are as follows:

Operating System: CentOS 5.10

Host Name: www

IP Address: 192.168.236.128

Gateway: 192.168.236.2

DNS: 8.8.8.8 8.8.4.4

Attached CentOS 5.10 system Mirror Download Address:

32-bit download address:

Http://mirrors.163.com/centos/5.10/isos/i386/CentOS-5.10-i386-bin-DVD-1of2.iso

64-bit Download address:

Http://mirrors.163.com/centos/5.10/isos/x86_64/CentOS-5.10-x86_64-bin-DVD-1of2.iso

Note:

1, the system mirrors has two files, installs the system to use only first, namely Centos-5.10-i386-bin-dvd-1of2.iso

The second mirror is the package that came with the system itself.

2, production server if it is large memory (more than 4G memory), it is recommended to install 64-bit version

Description: Before partitioning a disk, plan how to partition, how large each partition is set.

My zoning here is as follows

/boot 200MB #一般设置为200MB

SWAP1G (1024MB) #swap一般建议为物理内存的2倍大小

/ #剩余所有磁盘空间

Note: The formal production server can be divided into a separate/data partition, used to store data

Recommendation: All data are partitioned separately, the advantage of this is that if there is a problem with the system, will not affect the data, or need to reload the system, the data need not be transferred.

Configuring local yum sources using system mirroring files

1, use WinSCP.exe tool upload system image file Centos-5.10-i386-bin-dvd-1of2.iso to/usr/local/src directory

2. Connect to CentOS server remotely using Putty.exe tool

3. Mount System image files

Mkdir/media/cdrom #新建镜像文件挂载目录

CD/USR/LOCAL/SRC #进入系统镜像文件存放目录

LS #列出目录文件, you can see the system image file just uploaded

Mount-t iso9660-o loop/usr/local/src/centos-5.10-i386-bin-dvd-1of2.iso/media/cdrom #挂载系统镜像

Cd/media/cdrom #进入挂载目录, use the LS command to see that a file exists

4, set up automatically mounted system image files

Vi/etc/fstab #添加以下代码. Enable automatic mount on boot

/usr/local/src/centos-5.10-i386-bin-dvd-1of2.iso/media/cdrom iso9660 defaults,ro,loop 0 0

: wq! #保存退出

Note: iso9660 use df-t to view devices

5, use the Yum command to install the software

Yum--disablerepo=*--enablerepo=c5-media Clean all #清除yum缓存

Yum--disablerepo=*--enablerepo=c5-media makecache #缓存本地yum源中的软件包信息

Yum--disablerepo=*--enablerepo=c5-media Install httpd #安装apache

Yum--disablerepo=*--enablerepo=c5-media--skip-broken groupinstall "GNOME Desktop Environment"
