DRBD 4.1安装配置

yum install kernel* -y ##升级内核

reboot

wget http://oss.linbit.com/drbd/8.4/drbd-8.4.1.tar.gz ##下载drbd8.4.1

tar xvzf drbd-8.4.1.tar.gz

cd drbd-8.4.1

./configure --with-km --with-heartbeat ##--with-xen --with-pacemaker --with-rgmanager

make KDIR=/usr/src/kernels/2.6.18-274.12.1.el5xen-x86_64/ ##内核目录要与uname -a 输出的对应

make install KDIR=/usr/src/kernels/2.6.18-274.12.1.el5xen-x86_64/

modprobe drbd ##将drbd模块加载到内核

lsmod |grep drbd ##查看一下是否加载成功

drbdadm --version ##看一下版本输出

cp scripts/drbd /etc/init.d/ ##将drbd启动脚本复制到/etc下

/etc/init.d/drbd ##测试一下脚本的可用性

##drbd的配置文件在/usr/local/etc/drbd.d/下

cp scripts/global_common.conf /usr/local/etc/drbd.d/ ##复制全局配置文件/usr/local/etc/drbd.d/下还应有resource配置文件

cp scripts/drbd.conf* /usr/local/etc/ ##复制drbd-8.4.0/scripts/下的实例配置文件

chkconfig --level 2345 drbd on ##加入系统服务

默认安装后的配置文件在/usr/local/etc/

vim /usr/local/etc/drbd.conf

include "drbd.d/global_common.conf";
include "drbd.d/*.res";

vim /usr/local/etc/drbd.d/global_common.conf

resource r0 {
on server01 {
 volume 0 {
 device /dev/drbd0;
 disk /dev/xvdb5;
 flexible-meta-disk internal;
 }
 address 192.168.0.193:7788;
 }
on server02 {
 volume 0 {
 device /dev/drbd0;
 disk /dev/xvdb5;
 flexible-meta-disk internal;
 }
 address 192.168.0.194:7788;
 }
}

在两个节点上

dd if=/dev/zero of=/dev/xvdb5 bs=1M count=128

drbdadm create-md r0

/etc/init.d/drbd start

在主节点上

drbdsetup /dev/drbd0 primary --o

drbdadm primary r0

mkfs.xfs /dev/drbd0

mount /dev/drbd0 /drbd

drbdadm primary db
