Heartbeat + mysql +drbd
三个部分分别提供了高可用,数据库,以及存储服务。将之后的论坛整合成一个完整的体系
说明:server3,server4提供以上三个服务
1数据库
直接yum install mysql-server -y #server3和server4都做
mysql_secure_installation#安全初始化,设置root密码,否则数据库不要密码也能登陆
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都要安装
[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
##做测试可以用:server3.example.com IPaddr::172.25.50.200/24/eth0 mysqld(上面的是针对drbd所作的)
[root@server3 ha.d]# scp ha.cf haresources authkeys 172.25.50.40:/etc/ha.d/
两边都重新启动heartbeat
3.drbd共享存储
给server3和server4都划分一个4G的虚拟磁盘
[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
安装以下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也需要安装这些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;#自定义的共享磁盘名称
syncer {verify-alg sha1;
}
on server3.example.com {#节点的hostname
disk /dev/vdb;#自身主将用来设置成共享的磁盘路径
address 172.25.50.30:7789;#节点ip
}
on server4.example.com {
disk /dev/vda;
address 172.25.50.40:7789;
}
}
这样就无需担心发布共享磁盘名称不一样如何解决的问题了
[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
--== Thank you for participating in the global usage survey ==--
The server's response is:
Writing meta data...

New drbd meta data block successfully created.
[root@server3 drbd.d]# /etc/init.d/drbd start#server4同时启动

[root@server4 mount]# ls

[root@server4 mnt]# umount /mnt/mount/
[root@server4 mnt]# drbdadm secondary homework
在挂载的目录下看到在server3上创建的文件,说明分布式共享存储配置成功
Heartbeat+mysql
关闭两台虚拟机的 heartbeat 服务
[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
正在启动 mysqld: [确定]
[root@server3 ~]# cd
[root@server3 ~]# /etc/init.d/mysqld stop
停止 mysqld: [确定]
[root@server3 ~]# umount /var/lib/mysql/
[root@server3 ~]# drbdadm secondary homework
把server3,server4的heartbeat服务打开服务会自动开启,当server3的heatbeat服务关闭是。Vip:172.25.50.200会调转到server4上。
最后:
整合
现在我们来搭建一个论坛
[root@server1 mnt]# unzip Discuz_X3.2_SC_UTF8.zip -d /usr/local/nginx/html/
##将这个论坛压缩包解压在nginx的默认发布目录中
[root@server1 mnt]# cd /usr/local/nginx/html/
[root@server1 html]# ls
50x.html index.html nginx.php readme upload utility
[root@server1 html]# cd upload/
[root@server1 upload]# ls
admin.php connect.php forum.php member.php search.php uc_server
api cp.php group.php misc.php source userapp.php
api.php crossdomain.xml home.php plugin.php static
archiver data index.php portal.php template
config favicon.ico install robots.txt uc_client
[root@server1 upload]# chmod 777 config/
[root@server1 upload]# chmod 777 data/ -R
[root@server1 upload]# chmod 777 uc_* -R
在serer3上设置root用户可以远程登陆的权限
grant all privileges on *.* to "root"@"%" identified by "redhat";
Query OK, 0 rows affected (0.00 sec)
测试方法,在serer1上远程登陆172.25.50.200这个ip的数据库
并且在数据库中有解的权限即可。
在浏览器上:172.25.50.10/upload/
数据库写入测试:在server3上
高可用测试:
关闭server3上的heartbeat服务。
如图,可以看见heartbeat服务停了之后,sererv4自动接管数据库,这时查看数据库内容与在server3上看到的一致!
实验成功!!!!!!!!!!!!!!!!!!!!!!!!
