1：测试光盘

网上下载的CentOS5.0，刻成光盘，测试能够启动，在老黑上测试可以安装，但老黑提示只能用文本安装，当然，他不提示我也用文本形式安装。

2：安装过程

整个安装的过程，我基本都是采用默认。

以前的版本这个地方显示的是空硬盘，但这里好像就已经有分区了，这个地方是没有搞明白。我就把默认的都删除

分区我采用最简单的办法，分一个swap分区，320m，根分区5g，创建一个data的分区，占用全部剩下的空间，其实你也可以是根分区是占用全部空间。

这个就选择最小化的安装，什么都不选。声明：我这里还是选了一个FTP Server，方便下一步安装LAMP环境。

上面显示，安装了399个包，占用空间是665m。这个信息，如果你是图形化安装你是看不到的。

3：设置centos

centos5，这个地方进行的改动，不是在安装的过程设置，而是装完系统，第一次启动的时候进行设置。我在这里就把防火墙禁用了。如果这里你不进行设置，进入系统后，可以运行setup命令进行设置，出来的是同样的界面。禁用selinux的防火墙，你还可以通过修改配置文件

vi /etc/sysconfig/selinux

SELINUX=enforcing 改成--> SELINUX=disabled

这样你就可以进入系统。我们可以在这里设置启动的服务，也可以进入系统再设置。可以比较一下停用服务后内存的使用情况

运行ntsysv 或者setup，进行服务配置

只选择9项服务

acpid
anacron
auotfs
cpuspeed
crond
network
sshd
syslog
yum-updatesd

重新启动机器，你就会发现内存占用少了一半。

4：设置ssh

修改/etc/ssh/sshd.config两个地方，运行root帐户登陆和禁止使用dns，这样可以加快客户端登陆，否则ssh会做反向的dns查询。

PermitRootLogin yes

UseDNS no

service sshd restart

5：mount 光驱

其实由于我们的服务已经启动autofs，centos5已经是配置好autofs，

ls /misc/cd

你就可以看到现在光盘里的内容，如果不使用，缺省300秒就会unmount。

6：设置yum

本来打算把yum更新指向cd的，不过反复测试，没有成功。所有只能指向国内的yum，速度也很快

vi /etc/yum.repos.d/CentOS-Base.repo

rpm --import http://centos.ustc.edu.cn/centos/5.1/os/i386/RPM-GPG-KEY-CentOS-5

yum update

7：建立搜索的db

为了以后搜索查找文件快速，使用locate来查找文件，运行命令

updatedb

8：查看log

当你安装完系统后，会在你的root的帐户下产生两个log

你可以用命令来查询自己安装了多少个rpm包

rpm -qa > rpm.txt

我用命令查询发现是装了342个包，和install.log 是一样的。
