标签:heartbeat   nfs   drbd   自动挂载   故障切换   客户端   

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.com192.168.49.136nfs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。

[root@heartbeat01 ~]# tail -1 /etc/ha.d/haresources

heartbeat01.contoso.com  IPaddr::192.168.49.100/24/eth1 drbddisk::test Filesystem::/dev/drbd0::/data::ext4

[root@heartbeat02 ~]# 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

[root@server136 mnt]# showmount -e 172.16.49.100

Export list for 172.16.49.100:

/data 192.168.49.0/255.255.255.0

[root@server136 ~]# mount -t nfs 192.168.49.100:/data /data

[root@server136 ~]# cd /data

[root@server136 data]# mkdir nfsclient

[root@server136 data]# touch client.txt

[root@server136 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

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

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

[root@heartbeat01 ~]# 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

[root@heartbeat02 ~]# 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:

[root@heartbeat01 ~]# ip a |grep 49.100

    inet 192.168.49.100/24 scope global eth1

[root@heartbeat01 ~]# cat /proc/drbd

version: 8.3.16 (api:88/proto:86-97)

[root@heartbeat02 ~]# /etc/init.d/nfs status

2、在客户端上手动挂载nfs共享目录

[root@server136 ~]# showmount -e 192.168.49.100

Export list for 192.168.49.100:

/data 192.168.49.0/255.255.255.0

[root@server136 ~]# mount -t nfs 192.168.49.100:/data /data

[root@server136 ~]# 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

[root@server136 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:

[root@server136 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:

[root@heartbeat01 ~]# /etc/init.d/heartbeat stop

Stopping High-Availability services: Done.

2)heartbeat02:

[root@heartbeat02 ~]# ip a |grep 49.100

    inet 192.168.49.100/24 scope global eth1

[root@heartbeat02 ~]# cat /proc/drbd

version: 8.3.16 (api:88/proto:86-97)

2、然后再启动heartbeat01的heartbeat服务,再次查看故障切换的情况

1)heartbeat01

[root@heartbeat01 ~]# /etc/init.d/heartbeat start

Done.


[root@heartbeat01 ~]# ip a |grep 49.100

3、手动重启heartbeat01,查看故障切换的情况

1)heartbeat01

[root@heartbeat01 ~]# reboot

[root@heartbeat01 ~]#

The system is going down for reboot NOW!

2)heartbeat02

[root@heartbeat02 ~]# ip a|grep 49.100

    inet 192.168.49.100/24 scope global eth1

[root@heartbeat02 ~]# cat /proc/drbd

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;

1)heartbeat01

[root@heartbeat01 ~]# ip a |grep 49.100

    inet 192.168.49.100/24 scope global eth1

[root@heartbeat01 ~]# cat /proc/drbd

version: 8.3.16 (api:88/proto:86-97)

GIT-hash: a798fa7e274428a357657fb52f0ecf40192c1985 build by phil@Build64R6, 2014-11-24 14:51:37

2)heartbeat02

[root@heartbeat02 ~]# ip a |grep 49.100

    inet 192.168.49.100/24 scope global eth1

[root@heartbeat02 ~]# cat /proc/drbd

version: 8.3.16 (api:88/proto:86-97)

GIT-hash: a798fa7e274428a357657fb52f0ecf40192c1985 build by phil@Build64R6, 2014-11-24 14:51:37

rpc.rquotad (pid 6275) is running...

3)nfs客户端

[root@server136 scripts]# ls -l /data|wc -l

968

[root@heartbeat01 ~]# ls -l /data|wc -l

993

[root@heartbeat02 ~]# ls -l /data |wc -l

942

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。

[root@heartbeat01 ~]# 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:

[root@heartbeat01 ~]# cat /proc/drbd

version: 8.3.16 (api:88/proto:86-97)

GIT-hash: a798fa7e274428a357657fb52f0ecf40192c1985 build by phil@Build64R6, 2014-11-24 14:51:37

[root@heartbeat02 ~]# cat /proc/drbd

version: 8.3.16 (api:88/proto:86-97)

GIT-hash: a798fa7e274428a357657fb52f0ecf40192c1985 build by phil@Build64R6, 2014-11-24 14:51:37

 0: cs:WFConnection ro:Secondary/Unknown ds:UpToDate/DUnknown C r-----

    ns:0 nr:2324 dw:2436 dr:3093 al:3 bm:1 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:88

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

[root@heartbeat02 ~]# drbdadm disconnect test

[root@heartbeat02 ~]# drbdadm -- --discard-my-data connect test

[root@heartbeat02 ~]# cat /proc/drbd

version: 8.3.16 (api:88/proto:86-97)

[root@heartbeat01 ~]# drbdadm connect test

[root@heartbeat01 ~]# cat /proc/drbd

GIT-hash: a798fa7e274428a357657fb52f0ecf40192c1985 build by phil@Build64R6, 2014-11-24 14:51:37

 0: cs:Connected ro:Secondary/Primary ds:UpToDate/UpToDate C r-----

    ns:0 nr:7336 dw:9772 dr:3093 al:3 bm:3 lo:0 pe:0 ua:0 ap:0 ep:1 wo:f oos:0

此时,两台drbd主机的状态已经恢复到一致状态,脑裂的问题解决完毕。
