分配私網(wǎng)多IP

目前私網(wǎng)多IP功能只支持IPv4且白名單開(kāi)放，白名單申請(qǐng)請(qǐng)?zhí)峤还巍?/p>

您需要一臺(tái)支持私網(wǎng)多IP的ECS。支持私網(wǎng)多IP的ECS規(guī)格可通過(guò)接口DescribeInstanceTypes查詢。

為ECS的主網(wǎng)卡或輔助網(wǎng)卡分配私網(wǎng)多IP。分配私網(wǎng)多IP接口AssignPrivateIpAddresses。查詢分配的IP地址接口DescribeNetworkInterfaces。

配置私網(wǎng)多IP。登錄分配多IP的ECS，這時(shí)使用命令ifconfig不能看到分配的私網(wǎng)多IP，要使用ifconfig配置分配的IP之后才能看到。此時(shí)私網(wǎng)多IP配置完成，可以使用。

命令格式（此種配置方式重啟失效）：#?ifconfig?eth0:{new?ip?name}?{your?ip?address}?netmask?{your?netmask}?upfor?example:? #?ifconfig?eth0:0?192.168.1.1?netmask?255.255.255.0?up

回收私網(wǎng)多IP

使用接口DescribeNetworkInterfaces查詢分配的輔助IP地址。

使用接口UnassignPrivateIpAddresses回收私網(wǎng)多IP。

多IP使用注意事項(xiàng)

目前私網(wǎng)多IP功能只支持IPv4且白名單開(kāi)放，白名單申請(qǐng)請(qǐng)?zhí)峤还巍?/p>

狀態(tài)限制：

網(wǎng)卡必須為 已綁定（InUse）或 可用（Available）狀態(tài)。

主網(wǎng)卡分配回收私網(wǎng)多IP，其ECS必須為運(yùn)行中（Running）或者?已停止（Stopped）狀態(tài)

Quota限制，查詢規(guī)格私網(wǎng)IP Quota途徑：Helper文檔，或者接口DescribeInstanceTypes

當(dāng)網(wǎng)卡已經(jīng)掛載到實(shí)例上，實(shí)例上每個(gè)網(wǎng)卡分配的私網(wǎng)IP（包括主私網(wǎng)IP）個(gè)數(shù)不能大于實(shí)例規(guī)格私網(wǎng)IP Quota。

當(dāng)網(wǎng)卡為Available狀態(tài)，最多能分配10個(gè)私網(wǎng)IP。

當(dāng)網(wǎng)卡已經(jīng)分配的私網(wǎng)IP數(shù)量大于要掛載實(shí)例規(guī)格私網(wǎng)IP Quota，不允許掛載。

當(dāng)實(shí)例上網(wǎng)卡分配的私網(wǎng)IP數(shù)量大于目標(biāo)規(guī)格支持的私網(wǎng)IP Quota，不允許變配。

安全組

一個(gè)安全組內(nèi)最多2000個(gè)私網(wǎng)IP。

分配的輔助IP所屬的安全組和其網(wǎng)卡一致。

只支持VPC實(shí)例，按照指定IP地址分配輔助IP時(shí)，指定的IP地址必須在網(wǎng)卡所屬VPC內(nèi)未被使用。
