解决:

1	# ./configure --prefix=/usr/local/heartbeat --with-daemon-user=hacluster --with-daemon-group=haclient --enable-fatal-warnings=no LIBS='/lib64/libuuid.so.1'

五、Heartbeat配置
Heartbeat的配置主要涉及到ha.cf、haresources、authkeys这三个文件。其中ha.cf是主配置文件，haresource用来配置要让Heartbeat托管的服务，authkey是用来指定Heartbeat的认证方式。

1.配置ha.cf----主配置文件

123456789101112131415161718192021

# cat /usr/local/heartbeat/etc/ha.d/ha.cf |grep ^[^#]debugfile /var/log/ha-debug ##用于记录heartbeat的调试信息logfile/var/log/ha-log ##用于记录heartbeat的日志信息logfacilitylocal0 ##设置heartbeat的日志,这里用的是系统日志keepalive 2 ##设定心跳(监测)时间时间为2秒deadtime 30 ##指定若备用节点在30秒内未收到主节点心跳信号,则接管主服务器资源warntime 10 ##指定心跳延迟的时间为10秒,10秒内备节点不能接收主节点心跳信号， 即往日志写入警告日志，但不会切换服务initdead 120 ##系统启动或重启后预留的忽略时间段，取值至少为deadtime的两倍udpport 694 ##广播/单播通讯使用的Udp端口bcast eno16777736 # Linux ##使用网卡eno16777736发送心跳检测#mcast eth0 225.0.0.1 694 1 0 ##采用网卡eth0的Udp多播来组织心跳，一般在备用节点不止一台时使用。Bcast、ucast和mcast分别代表广播、单播和多播，是组织心跳的的方式，任选其一#ucast eno16777736 192.168.10.133 ##采用网卡eno16777736的udp单播来组织心跳，后面跟的IP地址为双机对方IP地址auto_failback on ##定义当主节点恢复后，是否将服务自动切回#watchdog /dev/watchdog ##可选配置，通过Heartbeat监控系统运行状态。node node1 ##主节点名称，与uname -n显示一致node node2 ##备用节点名称ping 192.168.10.1 ##通过ping网关检测心跳是否正常，仅用来测试网络respawn hacluster /usr/local/heartbeat/libexec/heartbeat/ipfail ##指定和heartbeat一起启动、关闭的进程，可选#apiauth ipfail gid=haclient uid=hacluster ##设置启动IPfail的用户和组

注：
①watchdog /dev/watchdog:可选配置，通过Heartbeat监控系统运行状态。该特性需在内核中载入"softdog"内核模块,用来生成实际的设备文件，如系统中没有该模块，需进行指定，重新编译内核。编译完成输入 "insmod softdog"加载模块，然后输入"grep misc /proc/devices"，输入"cat /proc/misc |grep watchdog"，最后生成设备文件:"mknod /dev/watchdog c 10 130" 即可使用

②espawn hacluster /usr/lib/heartbeat/ipfail:指定和heartbeat一起启动、关闭的进程，可选。这些进程一般是和heartbeat集成的插件，遇到故障可自动重启。IPfail进程用于检测和处理网络故障，需配合ping语句指定ping node检测网络连通性;hacluster表示启动IPfail进程的用户。

2.配置haresources-----资源文件
Haresources文件用于指定双机系统的主节点、集群IP、子网掩码、广播地址及启动服务集群资源，
文件每一行可包含一个或多个资源脚本名，资源间使用空格隔开，参数间使用两个冒号隔开，主节点
和备份节点中资源文件haresources要完全一样。

一般格式为:
node-name network <resource-group>
node-name表示主节点的主机名，必须和ha.cf文件中指定的节点名一致。network用于设定集群的
IP地址、子网掩码和网络设备标识等。resource-group用于指定需Heartbeat托管的服务(即这些
服务可由Heartbeat来启动和关闭)。

注意:这里指定的IP地址就是集群对外服务的IP地址;
如要托管这些服务，必须将服务写成可通过start/stop来启动或关闭的脚本，放到/etc/init.d/
或/etc/ha.d/resource.d/目录下，Heartbeat会根据脚本名称自动去/etc/init.d或者
/etc/ha.d/resource.d目录下找到相应脚本进行启动或关闭操作。

12	# cat /usr/local/heartbeat/etc/ha.d/haresources |grep -v "#"node1 IPaddr::192.168.10.222/24/eno16777736

node1是HA集群的主节点，IPaddr为heartbeat自带的执行脚本，heartbeat首先将执行/etc/ha.d/resource.d/IPaddr 192.168.10.222/24 start的操作，即虚拟一个子网掩码为255.255.255.0，IP为192.168.10.222的地址，此IP为heartbeat对外提供服务的网络地址，同时指定此IP使用的网络接口

注:如下有haresources详细中文解释

http://blog.chinaunix.net/uid-20788470-id-1841644.html

3.配置authkeys-----心跳密钥验证文件

123	# grep -v "#" /usr/local/heartbeat/etc/ha.d/authkeys auth 22 sha1 HI!

注:auth后填序号，可任意填写，但第二行开头必须为序号名，然后为验证方式，支持三种( crc md5 sha1 )方式验证，最后面是自定义密钥。

六、配置双机互信(可选)并复制文件至备机

HA-01(192.168.10.132):

12	ssh-keygen -t rsa -f ~/.ssh/id_rsa -P ''ssh-copy-id -i .ssh/id_rsa.pub root@192.168.10.133

HA-02(192.168.10.133):

12	ssh-keygen -t rsa -f ~/.ssh/id_rsa -P ''ssh-copy-id -i .ssh/id_rsa.pub root@192.168.10.132

复制配置文件至备机:

1	# scp /usr/local/heartbeat/etc/ha.d/* root@192.168.10.133:/usr/local/heartbeat/etc/ha.d/

七、测试

1234	# systemctl start httpd # /etc/init.d/heartbeat start ##开启heartbeat# getenforce 0# systemctl stop firewalld

查看log信息

123456

# tail /var/log/ha-logOct 26 10:07:18 node1 heartbeat: [2063]: ERROR: Illegal directive [ucast] in /usr/local/heartbeat/etc/ha.d//ha.cfOct 26 10:07:18 node1 heartbeat: [2063]: ERROR: Illegal directive [ping] in /usr/local/heartbeat/etc/ha.d//ha.cfOct 26 10:07:18 node1 heartbeat: [2063]: ERROR: Client child command [/usr/lib/heartbeat/ipfail] is not executableOct 26 10:07:18 node1 heartbeat: [2063]: ERROR: Heartbeat not started: configuration error.Oct 26 10:07:18 node1 heartbeat: [2063]: ERROR: Configuration error, heartbeat not started.

问题解决:
更改IPfail路径:

1	respawn hacluster /usr/local/heartbeat/libexec/heartbeat/ipfail

建立plugin软链接:

12	# ln -svf /usr/local/heartbeat/lib64/heartbeat/plugins/RAExec/* /usr/local/heartbeat/lib/heartbeat/plugins/RAExec/# ln -svf /usr/local/heartbeat/lib64/heartbeat/plugins/* /usr/local/heartbeat/lib/heartbeat/plugins/

继续查看log信息

1234567891011

问题解决:

12	# vi /usr/local/heartbeat/etc/ha.d/haresourcesnode1 IPaddr::192.168.10.222/24/eno16777736

注:haresources下需添加IPaddr::

问题:

1234567891011

解决:node2未关闭防火墙，systemctl stop firewalld关闭防火墙问题解决

问题:

123	# tail /var/log/ha-logIPaddr(IPaddr_192.168.10.222)[6854]:2015/10/26_17:20:58 ERROR: Setup problem: couldn't find command: ifconfig/usr/lib/ocf/resource.d//heartbeat/IPaddr(IPaddr_192.168.10.222)[6828]:2015/10/26_17:20:58 ERROR: Program is not installed

解决:yum install net-tools后即可使用ifconfig命令

重启heartbeat，继续查看log信息:
