# Amazon Machine ImageからWallarmをデプロイする
本記事では、[公式Amazon Machine Image (AMI)](https://aws.amazon.com/marketplace/pp/B073VRFXSD)を使用してAWS上にWallarmをデプロイする手順について説明します。
## ユースケース
Among all supported [Wallarm deployment options][deployment-platform-docs], AMI is recommended for Wallarm deployment in these **use cases**:
* Your existing infrastructure resides on AWS.
* You aim to deploy a security solution as a separate cloud instance, rather than installing it directly on frontend systems like NGINX.
## Requirements
* An AWS account
* Understanding of AWS EC2, Security Groups
* Any AWS region of your choice, there are no specific restrictions on the region for the Wallarm node deployment
Wallarm supports both single availability zone (AZ) and multi availability zone deployments. In multi-AZ setups, Wallarm Nodes can be launched in separate availability zones and placed behind a Load Balancer for high availability.
* Access to the account with the **Administrator** role in Wallarm Console for the [US Cloud](https://us1.my.wallarm.com/) or [EU Cloud](https://my.wallarm.com/)
* Executing all commands on a Wallarm instance as a superuser (e.g. `root`)
## Installation
### 1. Launch a Wallarm Node instance
Launch an EC2 instance using the [Wallarm NGINX Node AMI](https://aws.amazon.com/marketplace/pp/prodview-5rl4dgi4wvbfe).
Recommended configuration:
* Latest available [AMI version][latest-node-version]
* Any preferred AWS region
* EC2 instance type: `t3.medium` (for testing) or `m4.xlarge` (for production), [see cost guidance for details][aws-costs]
* [SSH key pair](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/create-key-pairs.html) for accessing the instance
* Appropriate [VPC and subnet](https://docs.aws.amazon.com/vpc/latest/userguide/what-is-amazon-vpc.html) based on your infrastructure
* [Security Group](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/creating-security-group.html) inbound access to ports 22, 80, and 443
!!! info "Using a security group preconfigured by Wallarm"
When you deploy the instance and create a security group, AWS prompts you to use the one preconfigured by Wallarm. This group already has all the necessary ports open for inbound access.
![!Preconfigured security group][img-security-group]
* [Security Group](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/creating-security-group.html) outbound access to:
* `https://meganode.wallarm.com` to download the Wallarm installer
* `https://us1.api.wallarm.com` for working with US Wallarm Cloud or to `https://api.wallarm.com` for working with EU Wallarm Cloud. If access can be configured only via the proxy server, then use the [instructions][wallarm-api-via-proxy]
* IP addresses below for downloading updates to attack detection rules and [API specifications][api-spec-enforcement-docs], as well as retrieving precise IPs for your [allowlisted, denylisted, or graylisted][ip-lists-docs] countries, regions, or data centers
=== "US Cloud"
```
34.96.64.17
34.110.183.149
35.235.66.155
34.102.90.100
34.94.156.115
35.235.115.105
```
=== "EU Cloud"
```
34.160.38.183
34.144.227.90
34.90.110.226
```
### 2. Connect to the Wallarm Node instance via SSH
[Use the selected SSH key](https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/connect-to-linux-instance.html) to connect to your running EC2 instance:
```bash
ssh -i <your-key.pem> admin@<your-ec2-public-ip>
You need to use the admin
username to connect to the instance.
3. Generate a token to connect an instance to the Wallarm Cloud¶
The Wallarm node needs to connect to the Wallarm Cloud using a Wallarm token of the appropriate type. An API token allows you to create a node group in the Wallarm Console UI, helping you organize your node instances more effectively.
Generate a token as follows:
6. インスタンスをWallarm Cloudに接続する¶
クラウドインスタンスのノードはcloud-init.pyスクリプトを介してCloudに接続します。このスクリプトは、提供されたトークンを使用してノードをWallarm Cloudに登録し、グローバルに監視modeを設定し、--proxy-pass
フラグに基づいてノードが正当なトラフィックを転送するように設定します。NGINXの再起動によってセットアップが完了します。
クラウドイメージから作成したインスタンス上でcloud-init.py
スクリプトを次のように実行します。
-
WALLARM_LABELS='group=<GROUP>'
はノードグループ名を設定します(既存の場合はそのまま、存在しない場合は新規作成されます)。これはAPIトークンを使用している場合にのみ適用されます。 -
<TOKEN>
はトークンのコピーされた値です。 -
<PROXY_ADDRESS>
はWallarmノードが正当なトラフィックをプロキシする先のアドレスです。アーキテクチャに応じて、これはアプリケーションインスタンスのIP、ロードバランサ、またはDNS名などの場合があります。
7. Wallarmインスタンスへのトラフィック送信の設定¶
Update targets of your load balancer to send traffic to the Wallarm instance. For details, please refer to the documentation on your load balancer.
8. Wallarmの動作のテスト¶
-
The request with test Path Traversal attack to an address of either the load balancer or the machine with the Wallarm node:
-
Open Wallarm Console → Attacks section in the US Cloud or EU Cloud and make sure the attack is displayed in the list.
Since Wallarm operates in the monitoring mode, the Wallarm node does not block the attack but registers it.
-
Optionally, test other aspects of the node functioning.
9. デプロイしたソリューションの微調整¶
The deployment is now complete. The filtering node may require some additional configuration after deployment.
Wallarm settings are defined using the NGINX directives or the Wallarm Console UI. Directives should be set in the following files on the Wallarm instance:
-
/etc/nginx/sites-enabled/default
defines the configuration of NGINX -
/etc/nginx/conf.d/wallarm.conf
defines the global configuration of Wallarm filtering node -
/etc/nginx/conf.d/wallarm-status.conf
defines the filtering node monitoring service configuration -
/opt/wallarm/wstore/wstore.yaml
with the postanalytics service (wstore) settings
You can modify the listed files or create your own configuration files to define the operation of NGINX and Wallarm. It is recommended to create a separate configuration file with the server
block for each group of the domains that should be processed in the same way (e.g. example.com.conf
). To see detailed information about working with NGINX configuration files, proceed to the official NGINX documentation.
Creating a configuration file
When creating a custom configuration file, make sure that NGINX listens to the incoming connections on the free port.
Below there are a few of the typical settings that you can apply if needed:
To apply the settings, restart NGINX on the Wallarm instance:
Each configuration file change requires NGINX to be restarted to apply it.
