1 HA IP地址類型
| IP類型 | 標(biāo)識(shí) | 全稱 | 說明 | 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說明：一般**_per為真實(shí)IP，**_svc為服務(wù)IP，或稱serviceIP
3.2 查看網(wǎng)卡和IP
$ ifconfig -a
$ netstat -in
4 通過命令方式直接查看
1、通過以下方式可以查看
$ cat /etc/hosts

# 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255.255.255.0
確認(rèn)網(wǎng)絡(luò)為net_ether_01的Persistent IP為db1
