********************************************
一、系统基本配置
master、slave都做如下配置。
1.配置/etc/hosts文件：
~]# vi /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.20.151 master
192.168.20.152 slave
2.禁用selinux：
~]# sed -i "7s/enforcing/disabled/" /etc/selinux/config
3.禁用或卸载iptables，这里我们将iptables卸载：
~]# rpm -e iptables --nodeps
4.运行yum update升级内核：
~]# yum update
Loaded plugins: fastestmirror, presto
Loading mirror speeds from cached hostfile
* base: mirrors.btte.net
………
5.格式化/dev/sdb
~]# fdisk -l
Disk /dev/sda: 10.7 GB, 10737418240 bytes
255 heads, 63 sectors/track, 1305 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00034d1a
Device Boot Start End Blocks Id System
/dev/sda1 * 1 26 204800 83 Linux
Partition 1 does not end on cylinder boundary.
/dev/sda2 26 157 1048576 82 Linux swap / Solaris
Partition 2 does not end on cylinder boundary.
/dev/sda3 157 1306 9231360 83 Linux
Disk /dev/sdb: 10.7 GB, 10737418240 bytes

Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0x00000000
~]# fdisk /dev/sdb
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0xf048a83b.
Changes will remain in memory only, until you decide to write them.
After that, of course, the previous content won't be recoverable.
Warning: invalid flag 0x0000 of partition table 4 will be corrected by w(rite)
WARNING: DOS-compatible mode is deprecated. It's strongly recommended to
switch off the mode (command 'c') and change display units to
sectors (command 'u').

5.重启：
~]# reboot
…………
The system is going down for reboot NOW!
二、安装DRBD 8.4.2（主备节点配置相同）
1.主备节点安装drbd编译环境：
~]# yum -y install gcc flex wget make kernel-devel kernel-headers git libxslt rpm-build automake autoconf
2.下载DRBD安装文件
~]# wget http://oss.linbit.com/drbd/8.4/drbd-8.4.2.tar.gz
3.解压并安装DRBD文件
~]# tar -zvxf drbd-8.4.2.tar.gz
~]# cd drbd-8.4.2
drbd-8.4.2]# ./configure --prefix=/usr/local/drbd --with-km
drbd-8.4.2]# make KDIR=/usr/src/kernels/`uname -r`/
drbd-8.4.2]# make install
4.安装配置DRBD驱动模块
drbd-8.4.2]# cd drbd
drbd-8.4.2]# make clean
drbd]# make KDIR=/usr/src/kernels/`uname -r`/
drbd]# cp drbd.ko /lib/modules/`uname -r`/kernel/lib/
drbd]# depmod #创建模块依赖关系的列表
drbd]# cp /usr/local/drbd/etc/rc.d/init.d/drbd /etc/rc.d/init.d/
drbd]# chkconfig --add drbd
drbd]# chkconfig drbd on
四、定义DRBD 配置文件 [b]（主备节点配置相同）[/b]
~]# cp /usr/local/drbd/etc/drbd.d/global_common.conf /usr/local/drbd/etc/drbd.d/global_common-bak.conf
~]# vi /usr/local/drbd/etc/drbd.d/global_common.conf
