4、添加资源文件:
[root@node1 ~]# vim /etc/drbd.d/mysql.res
resource mysql {
on node1.test.com {
device /dev/drbd0;
disk /dev/sdb1;
address 172.18.109.233:7789;
meta-disk internal;
}
on node2.test.com {
device /dev/drbd0;
disk /dev/sdb1;
address 172.18.109.235:7789;
meta-disk internal;
}
}
5、将配置文件为node2提供一份
[root@node1 ~]# scp /etc/drbd.d/{global_common.conf,mysql.res} node2:/etc/drbd.d/
global_common.conf 100% 2212 2.2KB/s 00:00
mysql.res 100% 291 0.3KB/s 00:00
6、初始化资源并启动服务
node1：
[root@node1 ~]# drbdadm create-md mysql
initializing activity log
NOT initializing bitmap
Writing meta data...
New drbd meta data block successfully created. #提示已经创建成功
[root@node1 ~]# start drbd start
start: Unknown job: drbd
[root@node1 ~]# service drbd start #启动服务
Starting DRBD resources: [
create res: mysql
prepare disk: mysql
adjust disk: mysql
adjust net: mysql
]
..........
***************************************************************
DRBD's startup script waits for the peer node(s) to appear.
- If this node was already a degraded cluster before the
reboot, the timeout is 0 seconds. [degr-wfc-timeout]
- If the peer was available before the reboot, the timeout
is 0 seconds. [wfc-timeout]
(These values are for resource 'mysql'; 0 sec -> wait forever)
To abort waiting enter 'yes' [ 32]: yes
