NetScaler CPX-Proxy auf Google Compute Engine bereitstellen

In diesem Bereitstellungshandbuch wird beschrieben, wie Sie NetScaler CPX mit Docker in Google Compute Engine (GCE) von Google Cloud mit NetScaler ADM bereitstellen können, das im Unternehmensnetzwerk ausgeführt wird. In dieser Bereitstellung gleicht NetScaler CPX, das auf GCE installiert ist, zwei Back-End-Server aus, und NetScaler ADM bietet Lizenzierungs- und Analyselösungen.

NetScaler CPX ist ein Container-basierter Proxy, der die vollständige Layer-7-Funktionalität, SSL-Offload, mehrere Protokolle und NITRO-API unterstützt. NetScaler ADM bietet Verwaltungs-, Lizenzierungs- und Analyselösungen. Als Lizenzserver bietet NetScaler ADM Berechtigungen für NetScaler CPX-Instanzen, die lokal oder in der Cloud ausgeführt werden.

CPX und CPX Express sind dieselben Images. Wenn Sie das CPX-Image mit NetScaler ADM lizenzieren und installieren, wird das CPX-Image im Docker App Store (Version 11 oder 12) zu einer vollständigen CPX-Instanz. Ohne Lizenz wird das CPX-Image zu einer CPX Express-Instanz, die 20 Mbit/s und 250 SSL-Verbindungen unterstützt.

Voraussetzungen

  • 2 GB Arbeitsspeicher und 1 vCPU für NetScaler CPX

  • Docker Open Source von GCE erhältlich

  • NetScaler ADM läuft lokal mit Internet- oder VPN-Verbindung zu GCE

Hinweis

Informationen zum Bereitstellen von NetScaler ADM finden Sie unter Bereitstellen von NetScaler ADM.

Konfigurationsschritte

Sie müssen die folgenden Schritte ausführen, um diese Bereitstellung zu konfigurieren.

  1. Installieren Sie Docker auf einer GCE VM.

  2. Konfigurieren Sie die Remote-API-Kommunikation mit der Docker-Instanz.

  3. Installieren Sie das NetScaler CPX-Image.

  4. Erstellen Sie eine CPX-Instanz.

  5. Lizenzieren Sie NetScaler CPX über NetScaler ADM.

  6. Konfigurieren Sie Load Balancing Services auf NetScaler CPX und überprüfen Sie die Konfiguration.

    1. Installieren Sie die NGINX-Webserver.

    2. Konfigurieren Sie NetScaler CPX für den Lastausgleich und überprüfen Sie die Lastverteilung auf beide Webdienste.

Schritt 1: Docker auf einer GCE VM installieren

Erstellen Sie in GCE eine Linux-Ubuntu-VM. Installieren Sie dann Docker mithilfe der im folgenden Beispiel gezeigten Befehle auf der VM:

  $ sudo curl –ssl https://get.docker.com/ | sh
  % Total % Received % Xferd Average Speed Time Time Time Current

  If you would like to use Docker as a non-root user, you should now consider
  adding your user to the "docker" group with something like:

  sudo usermod -aG docker albert\_lee

  Remember that you will have to log out and back in for this to take effect.

  WARNING: Adding a user to the "docker" group will grant the ability to run
  containers which can be used to obtain root privileges on the
  docker host.
  Refer to https://docs.docker.com/engine/security/security/\#docker-daemon-attack-surface
  for more information.

Schritt 2: Konfigurieren der Remote-API-Kommunikation mit der Docker-Instanz

Öffnen Sie den Port 4243 für die API-Kommunikation mit der Docker-Instanz. Dieser Port ist erforderlich, damit NetScaler ADM mit der Docker-Instanz kommunizieren kann.

Schritt 3: Installieren Sie NetScaler CPX Image

Holen Sie sich das NetScaler CPX-Image aus dem Docker App Store. Der CPX Express und der CPX haben dasselbe Image. Wenn Sie jedoch das CPX-Image mit NetScaler ADM lizenzieren und installieren, wird das Image zu einer vollständigen CPX-Instanz mit einer Leistung von 1 Gbit/s. Ohne Lizenz wird das Image zu einer CPX Express-Instanz, die 20 Mbit/s und 250 SSL-Verbindungen unterstützt.

Schritt 4: Erstellen einer NetScaler CPX-Instanz

Installieren Sie das NetScaler CPX-Image auf dem Docker-Host. Öffnen Sie Ports für bestimmte Dienste, wie im folgenden Beispiel gezeigt, und geben Sie eine IP-Adresse für NetScaler ADM an:

  bash-2.05b\# **CHOST=${1:-localhost}**
  bash-2.05b\# **echo | openssl s\_client -connect $CHOST:443 | openssl x509 -fingerprint -noout | cut -d'=' -f2**

Schritt 5: NetScaler CPX über NetScaler ADM lizenzieren

Unter der Annahme, dass NetScaler ADM lokal ausgeführt wird, sollten Sie überprüfen können, ob NetScaler CPX mit NetScaler ADM kommuniziert und Informationen sendet. Die folgenden Bilder zeigen, wie NetScaler CPX eine Lizenz von NetScaler ADM abruft.

Schritt 6: Konfigurieren Sie Load Balancing Services auf NetScaler CPX und überprüfen Sie die Konfiguration

Installieren Sie zunächst die NGINX-Webserver auf dem Docker-Host. Konfigurieren Sie anschließend den Lastenausgleich auf NetScaler CPX, um die beiden Webserver zu verteilen, und testen Sie die Konfiguration.

Installieren Sie die NGINX-Webserver

Verwenden Sie die im folgenden Beispiel gezeigten Befehle, um NGINX-Webserver zu installieren.

  $ sudo docker pull nginx

  latest: Pulling from library/nginx
