All-in-One Kurulum Aracılığıyla Dağıtım

Bir all-in-one installer, çeşitli ortamlarda Wallarm node'un NGINX için dinamik modül olarak kurulumu sürecini kolaylaştırmak ve standartlaştırmak amacıyla tasarlanmıştır. Bu yükleyici, işletim sisteminizin ve NGINX sürümünüzün tespitini otomatik olarak gerçekleştirir ve tüm gerekli bağımlılıkları kurar.

all-in-one installer, aşağıdaki işlemleri otomatik olarak gerçekleştirerek basit bir node kurulum süreci sunar:

  1. İşletim sisteminizin ve NGINX sürümünüzün kontrolü.

  2. Tespit edilen işletim sistemi ve NGINX sürümü için Wallarm depolarının eklenmesi.

  3. Bu depolardan Wallarm paketlerinin kurulması.

  4. Kurulan Wallarm modülünün NGINX ile entegrasyonu.

  5. Sağlanan token kullanılarak filtering node'un Wallarm Cloud'a bağlanması.

Kullanım Durumları

Among all supported Wallarm deployment options, this solution is the recommended one for the following use cases:

Adım 1: NGINX ve Bağımlılıkların Kurulumu

Install the latest NGINX version of:

  • NGINX stable (the latest supported version is v1.28.0) - see how to install it in the NGINX documentation.

  • NGINX Mainline (the latest supported version is v1.27.5) - see how to install it in the NGINX documentation.

  • NGINX Plus (the latest supported version is NGINX Plus R33) - see how to install it in the NGINX documentation.

  • Distribution-Provided NGINX - to install, use the following commands:

    sudo apt update 
sudo apt -y install --no-install-recommends nginx

    sudo apt-get update
sudo apt-get install nginx

    sudo yum -y update 
sudo yum install -y nginx

    sudo yum -y update 
sudo yum install -y nginx

    sudo yum -y update 
sudo yum install -y nginx

Adım 2: Wallarm Token'ının Hazırlanması

To install node, you will need a Wallarm token of the appropriate type. To prepare a token:

  1. Open Wallarm Console → Settings → API tokens in the US Cloud or EU Cloud.
  2. Find or create API token with the Node deployment/Deployment usage type.
  3. Copy this token.
  1. Open Wallarm Console → Nodes in the US Cloud or EU Cloud.
  2. Do one of the following:
    • Create the node of the Wallarm node type and copy the generated token.
    • Use existing node group - copy token using node's menu → Copy token.

Adım 3: All-in-One Wallarm Kurulum Aracının İndirilmesi

Wallarm suggests all-in-one installations for the following processors:

  • x86_64

  • ARM64 (beta)

To download all-in-one Wallarm installation script, execute the command:

curl -O https://meganode.wallarm.com/6.2/wallarm-6.2.0.x86_64-glibc.sh

curl -O https://meganode.wallarm.com/6.2/wallarm-6.2.0.aarch64-glibc.sh

Adım 4: All-in-One Wallarm Kurulum Aracının Çalıştırılması

  1. Run downloaded script:

    # If using the x86_64 version:
sudo env WALLARM_LABELS='group=<GROUP>' sh wallarm-6.2.0.x86_64-glibc.sh

# If using the ARM64 version:
sudo env WALLARM_LABELS='group=<GROUP>' sh wallarm-6.2.0.aarch64-glibc.sh

    The WALLARM_LABELS variable sets group into which the node will be added (used for logical grouping of nodes in the Wallarm Console UI).

    # If using the x86_64 version:
sudo sh wallarm-6.2.0.x86_64-glibc.sh

# If using the ARM64 version:
sudo sh wallarm-6.2.0.aarch64-glibc.sh

  2. Select US Cloud or EU Cloud.

  3. Enter Wallarm token.

Sonraki adımlarda verilen komutlar, x86_64 ve ARM64 kurulumu için aynıdır.

Adım 5: Wallarm Node'un Trafiği Analiz Etmeye Etkinleştirilmesi

By default, the deployed Wallarm Node does not analyze incoming traffic.

To enable traffic analysis and proxying of legitimate traffic, update the NGINX configuration file, typically located at /etc/nginx/sites-available/default.

The following minimal configuration adjustments are necessary:

  1. Set the Wallarm Node to wallarm_mode monitoring;. This mode is recommended for initial deployments and testing.

    Wallarm also supports more modes like blocking and safe blocking, which you can read more.

  2. Determine where the node should forward legitimate traffic by adding the proxy_pass directive in the required locations. This could be to the IP of an application server, a load balancer, or a DNS name.

  3. If present, remove the try_files directive from the modified locations to ensure traffic is directed to Wallarm without local file interference.

server {
    ...
+   wallarm_mode monitoring;
    location / { 
+        proxy_pass http://example.com;
-        # try_files $uri $uri/ =404;
    }
    ...
}

Adım 6: NGINX'in Yeniden Başlatılması

Restart NGINX using the following command:

sudo systemctl restart nginx

Adım 7: Wallarm Node'a Trafik Yönlendirilmesinin Yapılandırılması

Update targets of your load balancer to send traffic to the Wallarm instance. For details, please refer to the documentation on your load balancer.

Adım 8: Wallarm Node İşleyişinin Test Edilmesi

  1. Send the request with test Path Traversal attack to a protected resource address:

    curl http://localhost/etc/passwd

    If traffic is configured to be proxied to example.com, include the -H "Host: example.com" header in the request.

  2. Open Wallarm Console → Attacks section in the US Cloud or EU Cloud and make sure the attack is displayed in the list.

    Attacks in the interface

  3. Optionally, test other aspects of the node functioning.

Adım 9: Dağıtılan Çözümün İnce Ayarlanması

Varsayılan ayarlarla dinamik Wallarm modülü kurulmuştur. Dağıtım sonrasında filtering node ek konfigürasyon gerektirebilir.

Wallarm ayarları NGINX direktifleri veya Wallarm Console UI kullanılarak tanımlanır. Direktifler, Wallarm node'un bulunduğu makinede aşağıdaki dosyalara eklenmelidir:

  • Sunucu ve konum seviyesindeki ayarlar için: /etc/nginx/sites-available/default

  • Http seviyesindeki ayarlar için: /etc/nginx/nginx.conf

  • Wallarm node izleme ayarları için: /etc/nginx/wallarm-status.conf – Detaylı açıklama linkte mevcuttur.

  • Tarantool'dan istatistik toplayan collectd eklentisinin ayarları için: /opt/wallarm/etc/collectd/wallarm-collectd.conf.d/wallarm-tarantool.conf

Gerekirse uygulayabileceğiniz tipik ayarlardan bazıları şunlardır:

Başlatma Seçenekleri

As soon as you have the all-in one script downloaded, you can get help on it with:

sudo sh ./wallarm-6.2.0.x86_64-glibc.sh -- -h

Which returns:

...
Usage: setup.sh [options]... [arguments]... [filtering/postanalytics]

OPTION                      DESCRIPTION
-b, --batch                 Batch mode, non-interactive installation.
    --install-only          Initiates the first stage of the all-in-one installer in batch mode. Copies essential configurations, including files and binaries, and sets up NGINX for node installation, bypassing Cloud registration and activation. Requires --batch.
    --skip-ngx-config       Avoids automatic NGINX configuration changes that occur during the --install-only stage in batch mode, suitable for users who prefer manual adjustments later. When used with --install-only, it ensures only essential configurations are copied without altering NGINX settings. Requires --batch.
    --register-only         Initiates the second stage of the all-in-one installer in batch mode, completing the setup by registering the node in the Cloud and starting its service. Requires --batch.
-t, --token TOKEN           Node token, required in a batch mode.
-c, --cloud CLOUD           Wallarm Cloud, one of US/EU, default is EU, only used in a batch mode.
-H, --host HOST             Wallarm API address, for example, api.wallarm.com or us1.api.wallarm.com, only used in a batch mode.
-P, --port PORT             Wallarm API pot, for example, 443.
    --no-ssl                Disable SSL for Wallarm API access.
    --no-verify             Disable SSL certificates verification.
-f, --force                 If there is a node with the same name, create a new instance.
-h, --help
    --version

Batch mode

The --batch option triggers batch (non-interactive) mode, where the script requires configuration options via the --token and --cloud flags, along with the WALLARM_LABELS environment variable if needed. In this mode, the script does not prompt the user for data input step by step as in the default mode; instead, it requires explicit commands for interaction.

Below are examples of commands to run the script in batch mode for node installation, assuming the script has already been downloaded:

# If using the x86_64 version:
sudo env WALLARM_LABELS='group=<GROUP>' sh wallarm-6.2.0.x86_64-glibc.sh -- --batch -t <TOKEN> -c US

# If using the ARM64 version:
sudo env WALLARM_LABELS='group=<GROUP>' sh wallarm-6.2.0.aarch64-glibc.sh -- --batch -t <TOKEN> -c US

# If using the x86_64 version:
sudo env WALLARM_LABELS='group=<GROUP>' sh wallarm-6.2.0.x86_64-glibc.sh -- --batch -t <TOKEN>

# If using the ARM64 version:
sudo env WALLARM_LABELS='group=<GROUP>' sh wallarm-6.2.0.aarch64-glibc.sh -- --batch -t <TOKEN>

Separate execution of node installation stages

When preparing your own machine image using the all-in-one installer for cloud infrastructure, the standard installation process outlined in this article may not suffice. Instead, you will need to execute specific stages of the all-in-one installer separately to accommodate the requirements of creating and deploying a machine image:

  1. Build machine image: At this stage, it is necessary to download binaries, libraries, and configuration files of the filtering node and create a machine image based on them. Utilizing the --install-only flag, the script copies the required files and modifies NGINX configurations for node operation. If you wish to make manual adjustments, you can opt to bypass the NGINX file modification by using the --skip-ngx-config flag.

  2. Initialize a cloud instance with cloud-init: During instance initialization, the bootstrap phase (cloud registration and service start) can be executed using cloud-init scripts. This stage can be run independently from the build phase by applying the --register-only flag to the /opt/wallarm/setup.sh script copied during the build stage.

This functionality is supported starting from version 4.10.0 of the all-in-one installer in batch mode. The commands below enable the sequential execution of the outlined steps:

# If using the x86_64 version:
curl -O https://meganode.wallarm.com/6.2/wallarm-6.2.0.x86_64-glibc.sh
sudo sh wallarm-6.2.0.x86_64-glibc.sh -- --batch --install-only
sudo env WALLARM_LABELS='group=<GROUP>' /opt/wallarm/setup.sh --batch --register-only -t <TOKEN> -c US

# If using the ARM64 version:
curl -O https://meganode.wallarm.com/6.2/wallarm-6.2.0.aarch64-glibc.sh
sudo sh wallarm-6.2.0.aarch64-glibc.sh -- --batch --install-only
sudo env WALLARM_LABELS='group=<GROUP>' /opt/wallarm/setup.sh --batch --register-only -t <TOKEN> -c US

# If using the x86_64 version:
curl -O https://meganode.wallarm.com/6.2/wallarm-6.2.0.x86_64-glibc.sh
sudo sh wallarm-6.2.0.x86_64-glibc.sh -- --batch --install-only
sudo env WALLARM_LABELS='group=<GROUP>' /opt/wallarm/setup.sh --batch --register-only -t <TOKEN>

# If using the ARM64 version:
curl -O https://meganode.wallarm.com/6.2/wallarm-6.2.0.aarch64-glibc.sh
sudo sh wallarm-6.2.0.aarch64-glibc.sh -- --batch --install-only
sudo env WALLARM_LABELS='group=<GROUP>' /opt/wallarm/setup.sh --batch --register-only -t <TOKEN>

Finally, to complete the installation, you need to enable Wallarm to analyze traffic and restart NGINX.

Separate installation of filtering and postanalytics nodes

The filtering/postanalytics switch provides the option to install the postanalytics module separately. Without this switch, both filtering and postanalytics components are installed together by default.

API Discovery-only mode

You can use the node in API Discovery-only mode (available since version 5.3.7). In this mode, attacks - including those detected by the Node's built-in mechanisms and those requiring additional configuration (e.g., credential stuffing, API specification violation attempts, and malicious activity from denylisted and graylisted IPs) - are detected and blocked locally (if enabled) but not exported to Wallarm Cloud. Since there is no attack data in the Cloud, [Threat Replay Testing][threat-replay-testing-docs] does not work. Traffic from whitelisted IPs is allowed.

Meanwhile, [API Discovery][api-discovery-docs], [API session tracking][api-sessions-docs], and [security vulnerability detection][vuln-detection-docs] remain fully functional, detecting relevant security entities and uploading them to the Cloud for visualization.

This mode is for those who want to review their API inventory and identify sensitive data first, and plan controlled attack data export accordingly. However, disabling attack export is rare, as Wallarm securely processes attack data and provides [sensitive attack data masking][masking-sensitive-data-rule] if needed.

To enable API Discovery-only mode:

  1. Create or modify the /etc/wallarm-override/env.list file:

    sudo mkdir /etc/wallarm-override
sudo vim /etc/wallarm-override/env.list

    Add the following variable:

    WALLARM_APID_ONLY=true

  2. Follow the node installation procedure.

With the API Discovery-only mode enabled, the /opt/wallarm/var/log/wallarm/wcli-out.log log returns the following message:

{"level":"info","component":"reqexp","time":"2025-01-31T11:59:38Z","message":"requests export skipped (disabled)"}

Kurulumu Baştan Başlatma

Eğer mevcut Wallarm node kurulumu silinip yeniden başlatılacaksa, aşağıdaki adımları izleyin.

Kurulumu Baştan Başlatmanın Etkisi

Kurulumu yeniden başlatmak, mevcut Wallarm servislerinin durdurularak silinmesini içerir; bu da yeniden kurulum tamamlanana kadar trafik filtrelemesinin durmasına neden olur. Üretim veya kritik trafik ortamlarında dikkatli olun, çünkü bu durumda trafik filtrelenmemiş olur ve risk altına girer.

Mevcut bir node'u yükseltmek (örneğin, 4.10'dan 5.0'a) için, yükseltme talimatlarına bakın.

  1. Wallarm süreçlerini sonlandırın ve yapılandırma dosyalarını kaldırın:

    sudo systemctl stop wallarm
sudo rm -rf /opt/wallarm

  2. 2. adımden setup (kurulum) talimatlarını izleyerek yeniden kurulum sürecine devam edin.
