两端开启heartbeat服务
查看运行状态：tail -f /vat/log/messages
drbd
环境：server6 server7 两块大小相同的磁盘vda
安装：drbd-8.4.2.tar.gz
在server6中：
yum install kernel-devel
tar zxf drbd-8.4.2.tar.gz cd drbd-8.4.2
./configure --enable-spec --with-km
mv drbd-8.4.2.tar.gz tpmbuild/sources
rpmbuild -bb drbd.specrpmbuild -bb drbd-km.spec
cd rpmbuild/RPMS/x86_64安装所有生成的包并拷贝至server7中安装
配置：
cd /etc/drbd.d vim example.res
resource example {
meta-disk internal;
device /dev/drbd1;
syncer {
verify-alg sha1;
}
on server6.example.com {
disk /dev/vda;
address 172.25.254.6:7789;
}
on server7.example.com {
disk /dev/vda;
address 172.25.254.7:7789;
}
}
将此配置文件拷贝到server7的同目录下
在两个结点上进行格式化：
/etc/init.d/drbd start
drbdadm create-md example
drbdadm primary example --force
cat /proc/drbd 查看drbd状态
只有primary端才可以挂载
drbdadm secondary example
操作：
drbd-overview
drbdadm up/down example
drbd disconnect example
drbdadm connect --discard-my-data example
整合heartbeat+drbd:
vim /etc/ha.d/haresources
server6.example.com IPaddr::172.25.254.6/24/eth0
drbddisk::example Filesystem::/dev/drbd1::/var/www/html::ext4 httpd
