《HA网卡确认方法》

1 HA IP地址类型

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 IP
Service 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 -in

4 通过命令方式直接查看

1、通过以下方式可以查看

$ cat /etc/hosts
196.141.100.110       tredb01_boot1  tredb01
196.141.100.100       tredb02_boot1  tredb02
196.141.10.110     tredb01_boot2
196.141.10.100     tredb02_boot2
18.6.6.4         tredb02_svc
18.6.6.5         tredb01_per  db1
18.6.6.6         tredb02_per  db2

4 HA网卡SMIT查看方法（暂不完整）

4.1 根据hosts文件确认IP对应的别名

$ cat /etc/hosts
100.1.22.1       test1_boot1  test1
100.1.22.2       test2_boot1  test2
192.168.22.1     test1_boot2
192.168.22.2     test2_boot2
10.1.22.1        test1_svc
10.1.22.5        test1_per  db1
10.1.22.6        test2_per  db2

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
