生产环境部署Heartbeat
一、环境准备：
1.1、关闭防火墙
1.2、关闭Selinux
1.3、修改主机名（要求简单明了）
| [root@master ~]# hostname master |
[root@slave ~]# hostname slave |
1.4、网络配置
在青云上创建自管网络，分别在两台服务器上配置网卡IP
| [root@master ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1 DEVICE=eth1 TYPE=Ethernet IPADDR=192.168.1.41 BOOTPROTO=static NETMASK=255.255.255.0 ONBOOT=yes NM_CONTROLLED=yes HWADDR=52:54:C3:57:3D:6A |
[root@slave ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth1 DEVICE=eth1 TYPE=Ethernet IPADDR=192.168.1.42 BOOTPROTO=static NETMASK=255.255.255.0 ONBOOT=yes NM_CONTROLLED=yes HWADDR=52:54:76:AC:B5:9A
|
查看一下两台服务器eth1网卡的路由是否通畅：
| Master端 |
| [root@master ~]# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0 0.0.0.0 255.255.255.0 U 1 0 0 eth1 172.20.28.0 0.0.0.0 255.255.255.0 U 1 0 0 eth0 0.0.0.0 172.20.28.1 0.0.0.0 UG 0 0 0 eth0 |
| Slave端 |
| [root@slave ~]# route -n Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface 192.168.1.0 0.0.0.0 255.255.255.0 U 1 0 0 eth1 172.20.28.0 0.0.0.0 255.255.255.0 U 1 0 0 eth0 0.0.0.0 172.20.28.1 0.0.0.0 UG 0 0 0 eth0 |
| [root@master ha.d]# ifconfig eth0:1 10.1.6.41/24 up |
| 说明：此处指设置一个vip，且设置在master端。 |
小结：添加路由操作：
Master：[root@master ~]# route add -host 192.168.1.42 dev eth1
Slave”[root@slave ~]# route add -host 192.168.1.41 dev eth1
1.5、两边服务器Hosts
[root@master ha.d]# cat /etc/hosts
127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6
192.168.1.41 master
192.168.1.42 slave
小结：这里配置的IP是心跳线IP。
二、安装heartbeat服务（版本：heartbeat-3.0.4）
2.1 安装heartbeat软件包
[root@master ~]# yum install heartbeat -y
2.2 拷贝heartbeat配置文件
[root@master ~]# cp /usr/share/doc/heartbeat-3.0.4/{ha.cf,authkeys,haresources} /etc/ha.d/
[root@master ~]# ll /etc/ha.d/
-rw-r--r-- 1 root root 645 Nov 30 11:36 authkeys
-rw-r--r-- 1 root root 10502 Nov 30 11:36 ha.cf
-rwxr-xr-x 1 root root 745 Dec 3 2013 harc
-rw-r--r-- 1 root root 5905 Nov 30 11:36 haresources
drwxr-xr-x 2 root root 4096 Nov 30 11:24 rc.d
-rw-r--r-- 1 root root 692 Dec 3 2013 README.config
drwxr-xr-x 2 root root 4096 Nov 30 11:24 resource.d
-rw-r--r-- 1 root root 2082 Mar 24 2017 shellfuncs
2.3 编辑heartbeat配置文件
| [root@master ha.d]# egrep -Ev "^#|^$" ha.cf debugfile /var/log/ha-debug logfile /var/log/ha-log logfacility local1 keepalive 2 deadtime 30 warntime 10 initdead 60 mcast eth0 225.0.0.1 694 1 0 auto_failback on node master node slave crm no |
| [root@master ha.d]# cat /etc/ha.d/authkeys auth 1 1 sha1 0832bedde820a9bcf6858c0ff6e5e82a #这个authkeys是可用的，验证过了。 [root@slave ha.d]# chmod 600 /etc/ha.d/authkeys |
| [root@master ha.d]# egrep -Ev "^#|^$" haresources master IPaddr::10.1.6.41/24/eth0 |
[root@master ha.d]# egrep -Ev "^#|^$" haresources
master IPaddr::10.1.6.41/24/eth0
2.4 启动heartbeat服务
[root@slave ha.d]# /etc/init.d/heartbeat start
[root@slave ha.d]# cat /var/log/ha-log
Nov 30 13:35:17 slave heartbeat: [11068]: info: Pacemaker support: no

至此，heartbeat就配置完成了。
