More than 1 year has passed since last update.


はじめに

AlibabaCloudのロードバランサーを動かしてみる

をROSで起動してみます。

AlibabaCloudのECSを東京リージョンの最安値で起動してみる!(ROS版)

このテンプレートで起動しますと、SLBとECS(VPC上)のリソースが作成されます。


起動後の仕上げ

ロードバランサーとサーバがつながってますが

80ポートのヘルスチェックに落ちてます。

ECSに入って、nginxかhttpdを起動します。

[root@poc ~]# yum -y install nginx

[root@poc ~]# /bin/systemctl start nginx.service


さいごに

ロードバランサーのIPアドレスをブラウザで開く

となります。

ROSなので、削除すると一回で消えます。
