5、测试Heartbeat
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:
[root@zbdba1 etc]# cat drbd.conf
include "drbd.d/drbd.conf.example";
[root@zbdba1 etc]# cat drbd.d/drbd.conf.example
resource zbdba {
options {

# The disk section is possible on resource level and in each
# volume section
disk {
# If you have a resonable RAID controller
# with non volatile write cache (BBWC, flash)

}
}
}
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:

挂载mysql目录:
mkdir /mysql
mkfs.ext4 /dev/drbd0
mount /dev/drbd0 /mysql
查看DRBD状态:
[root@zbdba1 ~]# service drbd status

2、安装Mysql:
在zbdba1:
service mysql stop
umount /dev/drbd0
drbdadm secondary zbdba
scp /etc/my.cnf zbdba2:`pwd`
在zbdba2:
drbdadm primary zbdba
mount /dev/drbd0 /mysql
cp support-files/mysql.server /etc/init.d/mysql
chkconfig mysql on
启动mysql:
service mysql start
测试成功
4、安装Heartbeat:

5、测试Heartbeat:
1、直接关闭hearbeat
[root@zbdba1 ha.d]# service heartbeat stop
监控zbdba1上ha-log日志:
