配置 SSL

Neo4j SSL 框架可与 Neo4j Helm chart 一起使用。您可以为 bolt、https、cluster 和 backup 指定 SSL 策略对象。用于 Neo4j Helm 部署的 SSL 公共证书和私钥必须存储在 Kubernetes Secrets 中。

要启用 Neo4j SSL 策略，请在 Neo4j Helm 部署的 values.yaml 文件中配置 ssl.<policy name> 对象，以引用包含要使用的 SSL 证书和密钥的 Kubernetes Secrets。此示例展示了如何配置 bolt SSL 策略

ssl:
 bolt:
   privateKey:
     secretName: bolt-cert
     subPath: private.key
   publicCertificate:
     secretName: bolt-cert
     subPath: public.crt

当在 values.yaml 文件中指定私钥时，Neo4j ssl 策略将自动启用。要禁用策略，请将 dbms.ssl.policy.{{ $name }}.enabled: "false" 添加到 config 对象中。

当 https 启用时，未加密的 http 不会自动禁用。如果 https 已启用，请将 server.http.enabled: "false" 添加到 config 对象中以禁用 http。

有关配置 SSL 策略的更多信息，请参阅 SSL 框架配置。

以下示例展示了如何部署具有配置 SSL 策略的 Neo4j 集群。

创建自签名证书

如果您没有可用的自签名证书，请按照以下步骤创建一个

  1. 为自签名证书创建一个新文件夹。本示例使用 /neo4j-ssl 文件夹。

    mkdir neo4j-ssl
cd neo4j-ssl

  2. 使用 openssl 命令并通过 subj 参数传递所有值，为自签名证书创建 private.key 和 public.crt。

    openssl req -newkey rsa:2048 -nodes -keyout private.key -x509 -days 365 -out public.crt -subj "/C=GB/ST=London/L=London/O=Neo4j/OU=IT Department"

  3. 验证 private.key 和 public.crt 文件是否已创建

    ls -lst
    示例输出
    -rw-r--r--  1 user  staff  1679  28 Dec 15:00 private.key
-rw-r--r--  1 user  staff  1679  28 Dec 15:00 public.crt

创建 neo4j 命名空间并配置它在当前上下文中使用

kubectl create namespace neo4j
kubectl config set-context --current --namespace=neo4j

使用 tls Kubernetes secret 配置 SSL 策略

本示例展示了如何使用存储在 tls Kubernetes secret 中的自签名证书来配置用于集群内部通信的 SSL 策略。

  1. 使用 public.crt 和 private.key 文件创建 Kubernetes TLS secret

    您必须运行 Kubernetes 集群并安装 kubectl 命令。有关更多信息，请参阅先决条件。

    1. 要创建 TLS secret，请使用 tls 选项和 secret 名称，例如 neo4j-tls。

      kubectl create secret tls neo4j-tls --cert=/path/to/neo4j-ssl/public.crt --key=/path/to/neo4j-ssl/private.key

    2. 验证 secret 是否已创建

      kubectl get secret
      示例输出
      NAME                  TYPE                                  DATA   AGE
neo4j-tls             kubernetes.io/tls                     2      4s

    3. 验证 secret 是否包含 public.crt 和 private.key 文件

      kubectl get secret neo4j-tls -o yaml
      示例输出
      apiVersion: v1

  2. 使用创建的 secret 在 ssl-values.yaml 文件中配置 ssl 对象

    ssl:
# setting per "connector" matching neo4j config
  bolt:
    privateKey:
      secretName: neo4j-tls
      subPath: tls.key
    publicCertificate:
      secretName: neo4j-tls
      subPath: tls.crt
  https:
    privateKey:
      secretName: neo4j-tls
      subPath: tls.key
    publicCertificate:
      secretName: neo4j-tls
      subPath: tls.crt
    trustedCerts:
      sources:
      - secret:
          name: neo4j-tls
          items:
          - key: tls.crt
            path: public.crt
  cluster:
    privateKey:
      secretName: neo4j-tls
      subPath: tls.key
    publicCertificate:
      secretName: neo4j-tls
      subPath: tls.crt
    trustedCerts:
      sources:
      - secret:
          name: neo4j-tls
          items:
          - key: tls.crt
            path: public.crt
    revokedCerts:
      sources: [ ]

现在，您可以使用配置好的 ssl-values.yaml 文件和 Neo4j Helm chart 来部署 Neo4j 集群了。

使用 generic Kubernetes secret 配置 SSL 策略

本示例展示了如何使用存储在 generic Kubernetes secret 中的自签名证书来配置用于集群内部通信的 SSL 策略。

  1. 使用 public.crt 和 private.key 文件创建 Kubernetes generic secret

    您必须运行 Kubernetes 集群并安装 kubectl 命令。有关更多信息，请参阅先决条件。

    1. 获取 public.crt 和 private.key 的 Base64 编码值

      cat public.crt| base64
      cat private.key| base64

    2. 使用 public.crt 和 private.key 的 Base64 编码值，创建 secret.yaml 文件

      apiVersion: v1

  name: neo4j-tls
  namespace: neo4j
type: Opaque

    3. 使用 kubectl create 命令和 secret.yaml 文件创建通用 secret

      kubectl create -f /path/to/secret.yaml
      示例输出
      secret/neo4j-tls created

    4. 验证 secret 是否已创建

      kubectl get secret
      示例输出
      NAME        TYPE     DATA   AGE
neo4j-tls   Opaque   2      85s

  2. 使用创建的 secret 在 ssl-values.yaml 文件中配置 ssl 对象

    ssl:
# setting per "connector" matching neo4j config
  bolt:
    privateKey:
      secretName: neo4j-tls
      subPath: private.key
    publicCertificate:
      secretName: neo4j-tls
      subPath: public.crt
  https:
    privateKey:
      secretName: neo4j-tls
      subPath: private.key
    publicCertificate:
      secretName: neo4j-tls
      subPath: public.crt
    trustedCerts:
      sources:
      - secret:
          name: neo4j-tls
          items:
          - key: public.crt
            path: public.crt
  cluster:
    privateKey:
      secretName: neo4j-tls
      subPath: private.key
    publicCertificate:
      secretName: neo4j-tls
      subPath: public.crt
    trustedCerts:
      sources:
      - secret:
          name: neo4j-tls
          items:
          - key: public.crt
            path: public.crt
    revokedCerts:
      sources: [ ]

现在，您可以使用 ssl-values.yaml 文件和 Neo4j Helm chart 部署 Neo4j 集群了。

部署带有 SSL 证书的 Neo4j 集群

使用 Neo4j Helm chart 和 ssl-values.yaml 文件部署 Neo4j 集群。

  1. 安装 server-1

    helm install server-1 neo4j/neo4j --namespace neo4j --set neo4j.acceptLicenseAgreement=yes --set neo4j.password=my-password --set neo4j.name="my-cluster" --set neo4j.minimumClusterSize=3 --set neo4j.edition="enterprise" --set volumes.data.mode=defaultStorageClass -f ~/Documents/neo4j-ssl/ssl-values.yaml

  2. 对 server-2 和 server-3 重复上一步的命令。

  3. 验证 Neo4j 集群是否正在运行

    kubectl get pods
    示例输出
    NAME                       READY   STATUS    RESTARTS   AGE
server-1-0                   1/1     Running   0          2m
server-2-0                   1/1     Running   0          2m
server-3-0                   1/1     Running   0          2m

  4. 连接到其中一个服务器并验证 /certificates/cluster 目录是否包含证书

    kubectl exec -it server-1-0 -- bash
    neo4j@server-1-0:~$ cd certificates/
neo4j@server-1-0:~/certificates$ ls -lst
    示例输出

  5. 退出 Pod

    exit

  6. 使用安装时使用的 neo4j.name 检查 LoadBalancer 服务是否可用

    export NEO4J_NAME=my-cluster
kubectl get service ${NEO4J_NAME}-lb-neo4j
    示例输出
    NAME                  TYPE           CLUSTER-IP     EXTERNAL-IP     PORT(S)                                        AGE
my-cluster-lb-neo4j   LoadBalancer   10.0.134.210   20.237.50.207   7474:31168/TCP,7473:31045/TCP,7687:32708/TCP   3m30s

  7. 使用以下任一选项连接到 Neo4j 集群

    • Neo4j Browser

      1. 打开网页浏览器并输入 https://lb-EXTERNAL_IP:7473（在本例中为 https://20.237.50.207:7473/browser/）。您应该能看到 Neo4j 浏览器。

      2. 使用用户 neo4j 和部署核心时设置的密码（本例中为 my-password）进行认证。

      3. 通过运行 :sysinfo 或 SHOW SERVERS 验证集群是否在线

        Cluster sysinfo

      4. 运行 SHOW SETTINGS YIELD name, value WHERE name CONTAINS 'ssl' 以验证配置是否按预期部署。

    • Cypher Shell

      1. 打开终端并连接到其中一个集群 Pod

        kubectl exec -it server-1-0 -- bash

      2. 导航到 bin 目录并使用 cypher-shell 连接到 server-1

        neo4j@server-1-0:~$ cd bin
neo4j@server-1-0:~/bin$ ./cypher-shell -u neo4j -p my-password -a neo4j+ssc://server-1.neo4j.svc.cluster.local:7687
        示例输出
        Connected to Neo4j using Bolt protocol version 5.26 at neo4j+ssc://server-1.neo4j.svc.cluster.local:7687 as user neo4j.
Type :help for a list of available commands or :exit to exit the shell.
Note that Cypher queries must end with a semicolon.
neo4j@neo4j>

      3. 通过运行 SHOW SERVERS 验证集群是否在线

        neo4j@server-1-0:~/bin$ SHOW SERVERS;
        示例输出
        +-----------------------------------------------------------------------------------------------------------------------------------+

+-----------------------------------------------------------------------------------------------------------------------------------+

      4. 运行 SHOW SETTINGS YIELD name, value WHERE name CONTAINS 'ssl' 以验证配置是否按预期部署。

        示例输出
