1 HA IP地址類(lèi)型

IP類(lèi)型	標(biāo)識(shí)	全稱(chēng)	說(shuō)明	配置
boot ip	boot_ip	真實(shí)IP，物理IP	boot一般在計(jì)算機(jī)中指的是引導(dǎo)。這里指的是，操作系統(tǒng)裝入的IP地址，即物理網(wǎng)卡IP地址。	配置網(wǎng)卡
Persistent IP	per_ip	永久IP	Persistent 是持續(xù)的意思。這里是指一直在一臺(tái)服務(wù)器上的IP地址。	配置Persistent IP
Service IP	ser_ip	服務(wù)IP，浮動(dòng)IP	Service是提供服務(wù)的意思。這里指應(yīng)用訪問(wèn)的IP地址。	配置Service IP

2HA IP地址設(shè)置原則

序號(hào)	原則
1	HA集群每臺(tái)服務(wù)器配置兩個(gè)物理網(wǎng)卡，即使用兩個(gè)物理網(wǎng)卡IP作為boot_IP。
2	HA集群每臺(tái)服務(wù)器配置一個(gè)永久IP，即per_IP。依附在其中一個(gè)boot_IP。
3	HA集群只有一個(gè)服務(wù)IP，即ser_ip。存在于集群的某臺(tái)服務(wù)器。
4	服務(wù)IP所在的服務(wù)器，同樣依附在其中一個(gè)boot_IP上，且可與永久IP分布在不同的boot_ip。
5	HA集群服務(wù)器的一個(gè)boot_IP網(wǎng)卡down掉后，依附其上的per_IP和ser_IP會(huì)切換至另一個(gè)up的網(wǎng)卡。
6	A集群服務(wù)器的兩個(gè)boot_IP網(wǎng)卡都down掉后，per_IP將down掉，ser_IP才會(huì)切換至備機(jī)。

3 HA網(wǎng)卡日常查看方法

HA 集群配置規(guī)范，hosts別名不存在異議，且不存在多個(gè)物理網(wǎng)卡的情況下，一般可用下列方法確認(rèn)網(wǎng)卡。

3.1 查看hosts文件

1、查看主機(jī)名對(duì)應(yīng)的IP地址。
2、查看節(jié)點(diǎn)名對(duì)應(yīng)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

說(shuō)明：一般**_per為真實(shí)IP，**_svc為服務(wù)IP，或稱(chēng)serviceIP

3.2 查看網(wǎng)卡和IP

$ ifconfig -a
$ netstat -in

4 通過(guò)命令方式直接查看

1、通過(guò)以下方式可以查看

4 HA網(wǎng)卡SMIT查看方法（暫不完整）

4.1 根據(jù)hosts文件確認(rèn)IP對(duì)應(yīng)的別名

$ 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 根據(jù)serviceIP確認(rèn)Persistent IP的網(wǎng)絡(luò)

# smit hacmp
1、選擇 --> Initialization and Standard Configuration
2、選擇 --> Configure Resources to Make Highly Available
3、選擇 --> Configure Service IP Lables/Addresses
4、選擇 --> Add a Service IP Lable/Address
添加db1_svc，選擇網(wǎng)絡(luò) net_ether_01
“IP Lable/Address”選擇test1_svc

確認(rèn)獲取網(wǎng)絡(luò)為net_ether_01

4.3 根據(jù)Persistent IP的網(wǎng)絡(luò)得到Persistent IP

# smit hacmp
1、選擇 --> Initialization and Standard Configuration
2、選擇 --> Configure Resources to Make Highly Available
3、選擇 --> Configure Persistent Node IP Lables/Addresses
4、選擇 --> Add a Persistent Node IP Lable/Address
5、兩個(gè)節(jié)點(diǎn)分別按規(guī)劃配置。先配置節(jié)點(diǎn)db1
6、配置
“Network Name”net_ether_01
“Node IP Lable/Address”選擇db1
“Netmask”填寫(xiě)255.255.255.0

確認(rèn)網(wǎng)絡(luò)為net_ether_01的Persistent IP為db1
