Heartbeat + mysql +drbd

三個(gè)部分分別提供了高可用，數(shù)據(jù)庫(kù)，以及存儲(chǔ)服務(wù)。將之后的論壇整合成一個(gè)完整的體系

說明：server3，server4提供以上三個(gè)服務(wù)

1數(shù)據(jù)庫(kù)

直接yum install mysql-server -y  #server3和server4都做

mysql_secure_installation#安全初始化，設(shè)置root密碼，否則數(shù)據(jù)庫(kù)不要密碼也能登陸

2.Heartbeat

[root@server3 heartbeat]# ls

heartbeat-3.0.4-2.el6.x86_64.rpm        heartbeat-libs-3.0.4-2.el6.x86_64.rpm

heartbeat-devel-3.0.4-2.el6.x86_64.rpm  ldirectord-3.9.5-3.1.x86_64.rpm

Server3，server4都要安裝

[root@server3 heartbeat]# yum install * -y

[root@server3 heartbeat]# cd /etc/ha.d/

[root@server3 ha.d]# ls

harc  rc.d  README.config  resource.d  shellfuncs

[root@server3 ha.d]# cp /usr/share/doc/heartbeat-3.0.4/{authkeys,ha.cf,haresources} .

[root@server3 ha.d]# vim ha.cf

48 keepalive 2

56 deadtime 30

76 udpport 1111

91 bcast   eth0

157 auto_failback on

211         node    server3.example.com

212         node    server4.example.com

222 ping 172.25.50.250

254 respawn hacluster /usr/lib64/heartbeat/ipfail

262 apiauth ipfail gid=haclient uid=hacluster

[root@server3 ha.d]# vim authkeys

 23 auth 1

 24 1 crc

 25 #2 sha1 HI!

 26 #3 md5 Hello!

[root@server3 ha.d]# vim haresources

在文件最后添加：

server3.example.com IPaddr::172.25.50.200/24/eth0 drbddisk::homework Filesystem::/dev/drbd2::/var/lib/mysql::ext4 mysqld

##做測(cè)試可以用：server3.example.com IPaddr::172.25.50.200/24/eth0 mysqld（上面的是針對(duì)drbd所作的）

[root@server3 ha.d]# scp ha.cf haresources authkeys 172.25.50.40:/etc/ha.d/

兩邊都重新啟動(dòng)heartbeat

3.drbd共享存儲(chǔ)

給server3和server4都劃分一個(gè)4G的虛擬磁盤

[root@server3 mnt]# fdisk -l

Disk/dev/vdb: 4294 MB, 4294967296 bytes

16 heads, 63 sectors/track, 8322 cylinders

Units = cylinders of 1008 * 512 = 516096 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x00000000

[root@server4 drbd]# fdisk -l

Disk/dev/vda: 4294 MB, 4294967296 bytes

16 heads, 63 sectors/track, 8322 cylinders

Units = cylinders of 1008 * 512 = 516096 bytes

Sector size (logical/physical): 512 bytes / 512 bytes

I/O size (minimum/optimal): 512 bytes / 512 bytes

Disk identifier: 0x00000000

安裝以下rpm包

drbd-8.4.2-2.el6.x86_64.rpm

drbd-bash-completion-8.4.2-2.el6.x86_64.rpm

drbd-heartbeat-8.4.2-2.el6.x86_64.rpm

drbd-km-2.6.32_431.el6.x86_64-8.4.2-2.el6.x86_64.rpm

drbd-pacemaker-8.4.2-2.el6.x86_64.rpm

drbd-udev-8.4.2-2.el6.x86_64.rpm

drbd-utils-8.4.2-2.el6.x86_64.rpm

drbd-xen-8.4.2-2.el6.x86_64.rpm

[root@server3 drbd]# rpm -ivh *

Server4也需要安裝這些rpm包

[root@server3 mnt]# cd /etc/drbd.d/

[root@server3 drbd.d]# ls

global_common.conf

[root@server3 drbd.d]# vim homework.res

[root@server3 drbd.d]# cat homework.res

resource homework {

meta-disk internal;

device /dev/drbd2;#自定義的共享磁盤名稱

syncer {verify-alg sha1;

}

on server3.example.com {#節(jié)點(diǎn)的hostname

disk /dev/vdb;#自身主將用來(lái)設(shè)置成共享的磁盤路徑

address 172.25.50.30:7789;#節(jié)點(diǎn)ip

}

on server4.example.com {

disk /dev/vda;

address 172.25.50.40:7789;

}

}

這樣就無(wú)需擔(dān)心發(fā)布共享磁盤名稱不一樣如何解決的問題了

[root@server3 drbd.d]# scp homework.res 172.25.50.40:/etc/drbd.d/

[root@server3 drbd.d]# drbdadm create-md homework

##server3和server4都做

在掛載的目錄下看到在server3上創(chuàng)建的文件，說明分布式共享存儲(chǔ)配置成功

Heartbeat+mysql

關(guān)閉兩臺(tái)虛擬機(jī)的 heartbeat 服務(wù)

[root@server3 mnt]# /etc/init.d/mysqld stop

[root@server3 mnt]# drbdadm primary homework

[root@server3 mnt]# mount /dev/drbd2 /mnt/mount/

[root@server3 mount]# cd /var/lib/mysql/

[root@server3 mysql]# cp -r * /mnt/mount/

[root@server3 ~]# umount /mnt/mount/

[root@server3 ~]# mount /dev/drbd2 /var/lib/mysql/

[root@server3 ~]# chown mysql.mysql /var/lib/mysql/ -R

[root@server3 ~]# /etc/init.d/mysqld start

正在啟動(dòng) mysqld：                                          [確定]

[root@server3 ~]# cd

[root@server3 ~]# /etc/init.d/mysqld stop

停止 mysqld：                                              [確定]

[root@server3 ~]# umount /var/lib/mysql/

[root@server3 ~]# drbdadm secondary homework

把server3，server4的heartbeat服務(wù)打開服務(wù)會(huì)自動(dòng)開啟，當(dāng)server3的heatbeat服務(wù)關(guān)閉是。Vip：172.25.50.200會(huì)調(diào)轉(zhuǎn)到server4上。

最后：

整合

現(xiàn)在我們來(lái)搭建一個(gè)論壇

[root@server1 mnt]# unzip Discuz_X3.2_SC_UTF8.zip -d /usr/local/nginx/html/

在serer3上設(shè)置root用戶可以遠(yuǎn)程登陸的權(quán)限

 grant all privileges on *.* to "root"@"%" identified  by "redhat";

測(cè)試方法，在serer1上遠(yuǎn)程登陸172.25.50.200這個(gè)ip的數(shù)據(jù)庫(kù)

并且在數(shù)據(jù)庫(kù)中有解的權(quán)限即可。

在瀏覽器上：172.25.50.10/upload/

數(shù)據(jù)庫(kù)寫入測(cè)試：在server3上

高可用測(cè)試：

關(guān)閉server3上的heartbeat服務(wù)。

如圖，可以看見heartbeat服務(wù)停了之后，sererv4自動(dòng)接管數(shù)據(jù)庫(kù)，這時(shí)查看數(shù)據(jù)庫(kù)內(nèi)容與在server3上看到的一致！
