篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Heartbeat+Drbd+NFS高可用实现相关的知识，希望对你有一定的参考价值。
继续之前的操作，来完成heartbeat+drbd+nfs高可用的实现。
heartbeat+drbd还是使用原来的环境即可，然而需要添加一台nfs客户端，客户端的信息如下：
| 主机名 | IP地址 | 角色 |
| server136.contoso.com | 192.168.49.136 | nfs客户端 |
一、环境准备
1）注意：因为我的客户端是192.168.49.0/24端，所以这里需要把VIP改为这个网段，所以先修改两个节点的haresources文件，将VIP修改为192.168.49.100。可以根据实际情况来看是否需要这一步操作。
[[email protected] ~]# tail -1 /etc/ha.d/haresources
heartbeat01.contoso.com IPaddr::192.168.49.100/24/eth1 drbddisk::test Filesystem::/dev/drbd0::/data::ext4
[[email protected] ~]# tail -1 /etc/ha.d/haresources
heartbeat01.contoso.com IPaddr::192.168.49.100/24/eth1 drbddisk::test Filesystem::/dev/drbd0::/data::ext4
2）两个drbd节点要安装nfs（以下操作需要在两个节点上操作）
yum -y install rpcbind nfs-utils vi /etc/exports /data 192.168.49.0/255.255.255.0(rw,no_root_squash,no_all_squash,sync) /etc/init.d/rpcbind start chkconfig rpcbind on /etc/init.d/nfs start chkconfig nfs off chmod -R 777 /data
3)客户端上安装nfs
yum -y install rpcbind nfs-utils /etc/init.d/rpcbind start chkconfig rpcbind on
4)客户端上测试nfs挂载
showmount -e 192.168.49.100 mkdir /data mount -t nfs 192.168.49.100:/data /data echo "mount -t nfs 192.168.49.100:/data /data" >>/etc/rc.local
[[email protected] mnt]# showmount -e 172.16.49.100
Export list for 172.16.49.100:
/data 192.168.49.0/255.255.255.0
[[email protected] ~]# mount -t nfs 192.168.49.100:/data /data
[[email protected] ~]# cd /data
[[email protected] data]# mkdir nfsclient
[[email protected] data]# touch client.txt
[[email protected] data]# ls
10.txt 20.txt 30.txt 40.txt 50.txt 60.txt 70.txt 80.txt 90.txt client.txt
11.txt 21.txt 31.txt 41.txt 51.txt 61.txt 71.txt 81.txt 91.txt lost+found
12.txt 22.txt 32.txt 42.txt 52.txt 62.txt 72.txt 82.txt 92.txt nfsclient
13.txt 23.txt 33.txt 43.txt 53.txt 63.txt 73.txt 83.txt 93.txt
14.txt 24.txt 34.txt 44.txt 54.txt 64.txt 74.txt 84.txt 94.txt
15.txt 25.txt 35.txt 45.txt 55.txt 65.txt 75.txt 85.txt 95.txt
16.txt 26.txt 36.txt 46.txt 56.txt 66.txt 76.txt 86.txt 96.txt
17.txt 27.txt 37.txt 47.txt 57.txt 67.txt 77.txt 87.txt 97.txt
18.txt 28.txt 38.txt 48.txt 58.txt 68.txt 78.txt 88.txt 98.txt
19.txt 29.txt 39.txt 49.txt 59.txt 69.txt 79.txt 89.txt 99.txt
1.txt 2.txt 3.txt 4.txt 5.txt 6.txt 7.txt 8.txt 9.txt
二、修改heartbeat资源配置
1）添加nfs服务
因为两个节点都没有设置nfs开机启动，而是让heartbeat接管nfs服务，在主节点获取VIP之后，然后启动nfs服务，所以需要将nfs服务加入heartbeat资源中
2）添加脚本文件
添加一个脚本文件killnfsd，目的是在发生故障切换时，能保障客户端挂载nfs正常。因为如果没有该脚本，在NFS服务切换后，客户端需要重新mount一下nfs共享目录，才可以正常使用，否则会出现“stale NFS file handle”的错误。
vi /etc/ha.d/resource.d/killnfsd #!/bin/bash # killall -9 nfsd /etc/init.d/nfs restart exit 0 chmod +x /etc/ha.d/resource.d/killnfsd
3）编辑/etc/ha.d/haresources文件
vi /etc/ha.d/haresources
[[email protected] ~]# tail -1 /etc/ha.d/haresources
heartbeat01.contoso.com IPaddr::192.168.49.100/24/eth1 drbddisk::test Filesystem::/dev/drbd0::/data::ext4 nfs killnfsd
[[email protected] ~]# tail -1 /etc/ha.d/haresources
heartbeat01.contoso.com IPaddr::192.168.49.100/24/eth1 drbddisk::test Filesystem::/dev/drbd0::/data::ext4 nfs killnfsd
三、配置nfs共享并手动挂载测试
1、正常启动heartbeat
依次启动heartbeat01和heartbeat02上的heartbeat服务，然后分别到两个节点上查看：
heartbeat01：
[[email protected] ~]# ip a |grep 49.100
inet 192.168.49.100/24 scope global eth1
[[email protected] ~]# cat /proc/drbd
version: 8.3.16 (api:88/proto:86-97)

[[email protected] ~]# /etc/init.d/nfs status

2、在客户端上手动挂载nfs共享目录
[[email protected] ~]# showmount -e 192.168.49.100
Export list for 192.168.49.100:
/data 192.168.49.0/255.255.255.0
[[email protected] ~]# mount -t nfs 192.168.49.100:/data /data
[[email protected] ~]# ls /data
10.txt 20.txt 30.txt 40.txt 50.txt 60.txt 70.txt 80.txt 90.txt client.txt
11.txt 21.txt 31.txt 41.txt 51.txt 61.txt 71.txt 81.txt 91.txt lost+found
12.txt 22.txt 32.txt 42.txt 52.txt 62.txt 72.txt 82.txt 92.txt nfsclient
13.txt 23.txt 33.txt 43.txt 53.txt 63.txt 73.txt 83.txt 93.txt
14.txt 24.txt 34.txt 44.txt 54.txt 64.txt 74.txt 84.txt 94.txt
15.txt 25.txt 35.txt 45.txt 55.txt 65.txt 75.txt 85.txt 95.txt
16.txt 26.txt 36.txt 46.txt 56.txt 66.txt 76.txt 86.txt 96.txt
17.txt 27.txt 37.txt 47.txt 57.txt 67.txt 77.txt 87.txt 97.txt
18.txt 28.txt 38.txt 48.txt 58.txt 68.txt 78.txt 88.txt 98.txt
19.txt 29.txt 39.txt 49.txt 59.txt 69.txt 79.txt 89.txt 99.txt
1.txt 2.txt 3.txt 4.txt 5.txt 6.txt 7.txt 8.txt 9.txt
[[email protected] data]# touch test1.txt
此时，可以正常写入。
这里我添加一个脚本，来执行一个持续写入的任务，用来测试在故障切换过程中，向NFS共享目录/data中写入数据是否受影响。脚本内容如下：
#!/bin/bash
#
while true;do
for i in {1..1000}
do
touch /data/action$i.txt
sleep 2
done
done然后后台执行该脚本：
[[email protected] scripts]# sh wrnfs.sh & [1] 5272
四、故障切换测试
1、手工停止heartbeat01上的heartbeat服务，观察一下两个节点以及nfs客户单的状态：
1）heartbeat01:
[[email protected] ~]# /etc/init.d/heartbeat stop
Stopping High-Availability services: Done.
2）heartbeat02:
[[email protected] ~]# ip a |grep 49.100
inet 192.168.49.100/24 scope global eth1
[[email protected] ~]# cat /proc/drbd
version: 8.3.16 (api:88/proto:86-97)

注意：上面将heartbeat01的网卡eth1停掉，之所以没有发生脑裂是因为我在/etc/drbd.d/test.res中配置文件中的节点地址是192.168.49.0/24段，也就是eth0的网段，所以没有发生裂脑。
5、下面将该配置修改为172.16.49.0/24段，再进行测试：
on heartbeat01.contoso.com {
device /dev/drbd0;
disk /dev/sdb1;
address 172.16.49.133:7788;
flexible-meta-disk internal;
}
on heartbeat02.contoso.com {
device /dev/drbd0;
disk /dev/sdb1;
address 172.16.49.134:7788;
meta-disk internal;

此时，客户端虽然仍在进行数据写入，但是数据是写入到heartbeat01中，而且此时两个节点都有192.168.49.100这个IP地址，drbd中每个节点对端的状态都是Unknown状态，这就是典型的脑裂状况。
[[email protected] ~]# ifup eth1
Determining if ip address 172.16.49.133 is already in use for device eth1...
将heartbeat01的eth1启动后，发现heartbeat的裂脑状态消除，然而，drbd两个节点的状态依然不对，如下：
[[email protected] ~]# cat /proc/drbd

五、发生脑裂的处理
1）在secondary主机上执行如下命令：
drbdadm secondary test drbdadm disconnect test drbdadm -- --discard-my-data connect test
2）在Primary主机上执行如下命令：
drbdadm disconnect all drbdadm connect test
[[email protected] ~]# drbdadm disconnect test
[[email protected] ~]# drbdadm -- --discard-my-data connect test
[[email protected] ~]# cat /proc/drbd
