某电商网站线上drbd+heartbeat+nfs配置
1、环境nfs1.test.com 10.1.1.1
nfs2.test.com 10.1.1.2
2、drbd配置
安装drbd
yum -y install gcc gcc-c++ make glibc flex
yum -y install drbd kmod-drbd
加载drbd模块
modprobe drbd
lsmod | grep drbd
/etc/drbd.conf配置
resource r0 {
protocol C;
startup { wfc-timeout 0; degr-wfc-timeout 120; }
disk { on-io-error detach; }
net {
timeout 60;
connect-int 10;
ping-int 10;
max-buffers 2048;
max-epoch-size 2048;
}
syncer { rate 50M; }
on nfs1.ewiz.com {
device /dev/drbd0;
disk /dev/sdb1;
address 10.1.1.1:7777;
meta-disk internal;
}
on nfs2.ewiz.com {
device /dev/drbd0;
disk /dev/sdb1;
address 10.1.1.2:7777;
meta-disk internal;
}
}
初始化drbd并启动
drbdadm create-md r0
/etc/init.d/drbd start
chkconfig drbd on
将nfs1上的drbd提升为主
# drbdsetup /dev/drbd0 primary -o
查看两台服务器drbd状态
# cat /proc/drbd
Connected st:Primary/Secondary
# cat /proc/drbd
Connected st:Secondary/Primary
格式化并挂载drbd设备
# mkdir /d
# mkfs.ext3 /dev/drbd0
# mount /dev/drbd0 /d
3、NFS配置
yum install -y nfs
vim etc/exports
/d 10.1.1.200(rw,sync,no_root_squash)
/d 10.1.1.201(rw,sync,no_root_squash)
/d 10.1.1.202(rw,sync,no_root_squash)
service nfs start
chkconfig nfs on
4、heartbeat配置
yum install -y heartbeat
/etc/ha.d/ha.cf配置如下：
logfile /var/log/ha-log
logfacility local0
keepalive 2
deadtime 5
ucast eth0 10.1.1.2 #此为nfs1上配置，nfs2上改为10.1.1.1
auto_fallback off
node nfs1.test.comnfs2.test.com
/etc/ha.d/authkeys配置如下：
auth 1
1 crc
/etc/ha.d/haresources配置如下：
nfs1.ewiz.com IPaddr::10.1.1.3/24/eth0 drbddisk::r0 Filesystem::/dev/drbd0::/d::ext3 killnfsd
/etc/ha.d/resource.d/killnfsd配置如下：
killall -9 nfsd; /etc/init.d/nfs restart; exit
给/etc/ha.d/resource.d/killnfsd可执行权限：
chmod +x /etc/ha.d/resource.d/killnfsd
启动heartbeat：
/etc/init.d/heartbeat start
5、客户端挂载
mount -t nfs 1.1.1.3:/d /web
