Azure の CentOS 8.3 を無料になった Miracle Linux 8.4 にマイグレーションしてみた
背景と目的
CentOS 8 のサポート終了に向けて、既存の CentOS 8.3 を簡単に Miracle Linux へマイグレーション出来るのか試してみました。
前提条件
コマンドの実施環境は、Mac + Azure CLI です。
bash
$ sw_vers
ProductName: macOS
ProductVersion: 12.0.1
BuildVersion: 21A559
$ az version
{
"azure-cli": "2.30.0",
"azure-cli-core": "2.30.0",
"azure-cli-telemetry": "1.0.6",
"extensions": {}
}
実施内容
bash
# 環境変数を設定します
region=japaneast
prefix=mnrcentos
# VM のパスワードを生成します
vmpass=$(openssl rand -base64 16)
echo $vmpass
# リソースグループを作成します
az group create \
--name ${prefix}-rg \
--location $region
# VM イメージを探します
az vm image list \
--offer centos \
--publisher openlogic \
--sku 8_3 \
--all \
--output table
Offer Publisher Sku Urn Version

--storage-sku Standard_LRS
# NSG に自身のパブリック IP から SSH 接続出来るようにします
az network nsg rule create \
--resource-group ${prefix}-rg \
--name Allow-SSH \
--nsg-name $(az network nsg list \
--resource-group ${prefix}-rg \
--query "[].name" \
--out tsv) \
--priority 100 \
--source-address-prefixes $(curl -s inet-ip.info) \

# VM に SSH 接続します
ssh azureuser@$(az vm show \

--query publicIps \
--output tsv)
実施結果
Miracle Linux へのマイグレーションは、とても簡単でした。
