IP类型标识全称说明配置boot ipboot_ip真实IP物理IPboot一般在计算机中指的是引导。这里指的是操作系统装入的IP地址即物理网卡IP地址。配置网卡Persistent IPper_ip永久IPPersistent 是持续的意思。这里是指一直在一台服务器上的IP地址。配置Persistent IPService IPser_ip服务IP浮动IPService是提供服务的意思。这里指应用访问的IP地址。配置Service IP
2HA IP地址设置原则
序号原则1HA集群每台服务器配置两个物理网卡即使用两个物理网卡IP作为boot_IP。2HA集群每台服务器配置一个永久IP即per_IP。依附在其中一个boot_IP。3HA集群只有一个服务IP即ser_ip。存在于集群的某台服务器。4服务IP所在的服务器同样依附在其中一个boot_IP上且可与永久IP分布在不同的boot_ip。5HA集群服务器的一个boot_IP网卡down掉后依附其上的per_IP和ser_IP会切换至另一个up的网卡。6A集群服务器的两个boot_IP网卡都down掉后per_IP将down掉ser_IP才会切换至备机。
3 HA网卡日常查看方法
HA 集群配置规范hosts别名不存在异议且不存在多个物理网卡的情况下一般可用下列方法确认网卡。
3.1 查看hosts文件
1、查看主机名对应的IP地址。 2、查看节点名对应的IP地址。
$ cat /etc/hosts
100.1.0.1 test1_boot1 test1
100.1.0.2 test2_boot1 test2
192.168.0.1 test1_boot2
192.168.0.2 test2_boot2
10.1.0.1 test1_svc
10.1.0.2 test2_svc
10.1.0.5 test1_per
10.1.0.6 test2_per
说明一般**_per为真实IP**_svc为服务IP或称serviceIP
3.2 查看网卡和IP
$ ifconfig -a
$ netstat -in4 通过命令方式直接查看
1、通过以下方式可以查看
$ cat /etc/hosts

196.141.100.100 tredb02_boot1 tredb02

4.2 根据serviceIP确认Persistent IP的网络
# smit hacmp
1、选择 -- Initialization and Standard Configuration
2、选择 -- Configure Resources to Make Highly Available
3、选择 -- Configure Service IP Lables/Addresses
4、选择 -- Add a Service IP Lable/Address
添加db1_svc选择网络 net_ether_01
“IP Lable/Address”选择test1_svc确认获取网络为net_ether_01
4.3 根据Persistent IP的网络得到Persistent IP
# smit hacmp
1、选择 -- Initialization and Standard Configuration
2、选择 -- Configure Resources to Make Highly Available
3、选择 -- Configure Persistent Node IP Lables/Addresses
4、选择 -- Add a Persistent Node IP Lable/Address
5、两个节点分别按规划配置。先配置节点db1
6、配置
“Network Name”net_ether_01
“Node IP Lable/Address”选择db1
“Netmask”填写255.255.255.0确认网络为net_ether_01的Persistent IP为db1
