1、安装DRBD
下载drbd：
wget http://oss.linbit.com/drbd/8.4/drbd-8.4.0.tar.gz
在zbdba1、zbdba2：
添加磁盘
Disk /dev/sdb: 8589 MB, 8589934592 bytes 255 heads, 63 sectors/track, 1044 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: 0x00000000安装依赖包：
yum install gcc flex rpm-build kernel-devel docbook-style-xsl -y建立rpm目录：
rpmbuild ~解压并生成rpm包：
tar xvf drbd-8.4.0.tar.gz 尝试了8.4.3，版本太新 linux内核不兼容 ./configure make rpm make km-rpm 此时已经生成drbd的rpm包进入安装：
cd /root/rpmbuild/RPMS/x86_64 yum install * -y查看drbd模块：
modprobe drbd lsmod |grep drbd配置DRBD：
[root@zbdba1 etc]# cat drbd.conf
include "drbd.d/drbd.conf.example";
[root@zbdba1 etc]# cat drbd.d/drbd.conf.example

}
}

}
}
}
drbdadm create-md zbdba
[root@zbdba1 etc]# service drbd start
[root@zbdba2 etc]# service drbd start
在zbdba1：
drbdsetup /dev/drbd0 primary --force
监控传输速率：
[root@Dbrd1 etc]# watch cat /proc/drbd

挂载mysql目录：
mkdir /mysql
mkfs.ext4 /dev/drbd0
mount /dev/drbd0 /mysql
查看DRBD状态：

5、测试Heartbeat：
1、直接关闭hearbeat
