前面的博文中提过mysql的源码安装和drbd的内核模块的添加，有些报错的解决、安装、测试这里不再重复，只是稍微提一下，感兴趣的可以看前面的博文。
1.安装heartbeat、修改主配置文件及测试
1.安装heartbeat、修改主配置文件（服务端1）
[root@server1 mnt]# ls #安装包
heartbeat-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
heartbeat-libs-3.0.4-2.el6.x86_64.rpm
[root@server1 mnt]# yum install * -y #安装/mnt所有
[root@server1 mnt]# cd /usr/share/doc/heartbeat-3.0.4/ #切换
[root@server1 heartbeat-3.0.4]# ls
apphbd.cf authkeys AUTHORS ChangeLog COPYING COPYING.LGPL ha.cf haresources README
[root@server1 heartbeat-3.0.4]# cp ha.cf haresources authkeys/etc/ha.d/ #拷贝主配置文件、资源配置文件、认证文件到指定目录
[root@server1 heartbeat-3.0.4]# cd /etc/ha.d/
[root@server1 ha.d]# ls
authkeys ha.cf harc haresources rc.d README.config resource.d shellfuncs
[root@server1 ha.d]# vim ha.cf #进入主配置文件
34 logfacility local0
48 keepalive 2
56 deadtime 30
61 warntime 10
71 initdead 60
76 udpport 719 #udp协议端口号
91 bcast eth0
157 auto_failback on
#结点主机名，那个写在前面那个就是主，另一个就是备，如下：服务端1是主，服务端2是备
211 node server1.example.com
212 node server2.example.com
220 ping 172.25.25.250
253 respawn hacluster /usr/lib64/heartbeat/ipfail
259 apiauth ipfail gid=haclient uid=hacluster
[root@server1 ha.d]# vim haresources
150 server1.example.com IPaddr::172.25.25.100/24/eth0 httpd #主机名是主结点的主机名、添加虚拟ip、httpd服务
[root@server1 ha.d]# vim authkeys #进入认证文件
23 auth 1 #认证
24 1 crc #认证方式crc
root@server1 ha.d]# chmod 600 authkeys #修改认证文件的权限
[[root@server1 ha.d]# /etc/init.d/heartbeat start #开启heartbeat
服务端2和服务端1的配置完全相同，可以在服务端2安装好heartbeat的情况下，将服务端1配置好的文件考过去，放在相同的目录下，然后启动服务端2的heartbeat服务，如下;
[root@server1 ha.d]# scp ha.cf haresources authkeys root@172.25.25.112:/etc/ha.d/ #拷贝
root@172.25.25.112’s password:
[root@server2 ha.d]# /etc/init.d/heartbeat start #启动（服务端2）
在测试之前，服务端1和服务端2要安装httpd且有内容不同的测试页。注意：不要手动启动httpd，系统会自动启动。
2.测试 172.25.25.100
[root@server1 ha.d]# /etc/init.d/httpd stop #将服务端1的httpd停止，测试
Stopping httpd: [ OK ]
[root@server1 ha.d]# /etc/init.d/httpd start #开启httpd
Starting httpd: [ OK ]
2.编译、安装drbd内核模块及测试
1.编译、安装drbd内核模块
[root@server1 mnt]# ls
drbd-8.4.3.tar.gz
[root@server1 mnt]# tar zxf drbd-8.4.3.tar.gz #解压
[root@server1 mnt]# ls
drbd-8.4.3 drbd-8.4.3.tar.gz
[root@server1 mnt]# cd drbd-8.4.3
[root@server1 drbd-8.4.3]# https://blog.51cto.com/u_12218/configure –enable-spec –with-km
[root@server1 drbd-8.4.3]# rpmbuild -bb drbd.spec
error: File /root/rpmbuild/SOURCES/drbd-8.4.3.tar.gz: No suchfile or directory

[root@server1 drbd-8.4.3]# rpmbuild -bb drbd.spec
[root@server1 drbd-8.4.3]# rpmbuild -bb drbd-km.spec
[root@server1 drbd-8.4.3]# cd /root/rpmbuild/RPMS/x86_64/ #切换目录
[root@server1 x86_64]# ls #生成10个安装包

在服务端1和服务端2虚拟机中各添加一块虚拟磁盘或划分一个新的分区，然后进行下面的步骤：
[root@server1 x86_64]# cd /etc/drbd.d/ #切换到drbd的主配置文件目录
[root@server1 drbd.d]# vim dbdata.res #创建一个文件，后缀必须是.res
1 resource dbdata{
2 meta-disk internal;
3 device /dev/drbd1;
4 syncer {
5 verify-alg sha1; #设置主备机之间通信使用的信息算法
6 }
#每个主机的说明以”on”开头,后面是主机名.在后面的{}中为这个主机的配置
7 on server1.example.com{ #主机名
8 disk /dev/vdb; #磁盘名称
9 address172.25.29.1:7789; #ip加端口，端口是指定的
10 }
11 onserver2.example.com{
12 disk /dev/vdb;
13 address172.25.29.2:7789;
14 }
15 }
[root@server1 drbd.d]# scp dbdata.resroot@172.25.29.2:/etc/drbd.d/
root@172.25.29.2’s password:

3.将drdb、mysql写进heartbeat的文件里且测试
1.将drdb、mysql写进heartbeat的文件（服务端1）
[root@server1 ～]# yum install mysql-server -y #服务端1和服务端2都要安装mysql，不要手动启动
[root@server1 ~]# cat /proc/drbd #服务端1和服务端2要同为secondary
