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

最近实验室内部的mysql的root密码被修改了，需要想办法修改新密码。方法如下：
1， 关闭mysql服务
/etc/init.d/mysqld stop
2，使用–skip-grant-tables选项启动MySQL服务,可以修改/etc/inin.d/mysqld脚本启动位置增加此选项，
vi /etc/init.d/mysqld
在下面运行启动的语句里增加--skip-grant-tables
