Red Hat Enterprise Linux 6 使用报告
FiredFish 2010-12-11
在rhel6正式版发布的第二天，就在RedHat官网下载了rhel-server-6.0-x86_64-dvd.iso,在此将安装过程及安装后的一些基本信息与大家分享。
1.刻盘
本人下载的是rhel-server-6.0-x86_64，大小3.2G，280k的速度下载了5个小时，由于cpu不支持64位虚拟化，所以在物理机上进行安装
2.安装
通过光盘引导后，就出现的redhat6的安装界面，选择第一项开始安装，整个安装界面非常漂亮，步骤也很精简，磁盘分区支持最新ext4
我选择了base server进行安装，共有500多个包
3.进系统体验
内核：2.6.32-71.el6.x86_64 比Ubuntu 10.04还新（2.6.32-25-server）
安装后占用空间1.3G：
/dev/sda1 9.7G 1.3G 7.9G 14% /
运行等级：
[root@localhost ~]# runlevel
N 3
默认启用了selinux:
[root@localhost ~]# sestatus
SELinux status: enabled
SELinuxfs mount: /selinux
Current mode: enforcing
Mode from config file: enforcing
Policy version: 24
Policy from config file: targeted
开机启动的服务，不必要的建议关闭：
