Install RedHat Enterprise Linux 3.0:
Put CD1 in your CD drive and reboot.
Make sure you select the smb-server packages during the install. You need that package to run Samba for Windows file-sharing.
Follow the install for your hardware and set up the boot disk to
your liking. Be sure and leave some extra room on the disk (a least an
extra 2-5 Gb) if you plan to encapsulate the boot volume.
Pay attention to how you setup the Ethernet cards. In Linux your
cards will most likely be eth0, eth1, eth2. In my case I had two
on-board Ethernet ports and one PCI based Ethernet card. Most Linux
installs will recognize the on-board NIC ports first and then any PCI
slots. During the install, I configured the public interface as eth2
and left the on-board cards (eth0 and eth1) for the heartbeat network.
Keep that in mind for the VCS install later.
Finally, you should try to configure X for your hardware. This will
come in handy later for running the GUIs locally. Of course, you can
always connect remotely from another workstation.
After both systems have rebooted, make sure you add the other node�s
hostname to the /etc/hosts file on both machines. So linuxnode1 will
look like this and linuxnode2 should be just the opposite:
[root@linuxnode1]# cat /etc/hosts
127.0.0.1 linuxnode1 localhost.localdomain localhost
192.168.1.113 linuxnode2
Install VM:
Time to install the RPMs. Order is important.
cd to the rpms directory on the fst_ha.lxrt2.2 CD and run this command:
rpm -Uvh VRTSvlic-3.00-008.i686.rpm
VRTSvxvm-3.2-update4_RH.i686.rpm VRTSvmdoc-3.2-update4

1、升级系统
yum check-update
yum update
2、安装一些常用的工具
yum install ntp iptraf sysstat screen subversion wget bzip2 nfs-utils vim-common
3、设置每天自动核准时间
# crontab -e
0 * * * * /usr/sbin/ntpdate 210.72.145.44
:wq
4、安装一些开发包
# yum install make gcc gcc-c++ libjpeg-devel ......
想要通过普通的静态策略路由来实现电信网通双线基本上是不可能的，因为那将需要维护相当大的一个IP段的数据库，而且还需要随时更新才能保证效果。
后来听前辈们说，可以采用基于源地址路由的方式来处理，让进来的数据，从哪个IP进来就从哪个IP返回。
下面就是一个在生产中得到了实际应用的脚本：

功能描述：
获取一些文件相关的信息。
用法：
#include <sys/types.h>
#include <sys/stat.h>
#include <unistd.h>
int stat(const char *path, struct stat *buf);
int fstat(int filedes, struct stat *buf);
int lstat(const char *path, struct stat *buf);
参数：
path：文件 ......
