KubeSphere 审计日志系统提供了一套与安全相关并按时间顺序排列的记录,按顺序记录了与单个用户、管理人员或系统其他组件相关的活动。对 KubeSphere 的每个请求都会生成一个事件,然后写入 Webhook,并根据一定的规则进行处理。
|
||
|
||
有关更多信息,请参见[审计日志查询](../../toolbox/auditing/auditing-query/)。
|
||
|
||
## 在安装前启用审计日志
|
||
|
||
### 在 Linux 上安装
|
||
|
||
当您在 Linux 上安装多节点 KubeSphere 时,需要创建一个配置文件,该文件列出了所有 KubeSphere 组件。
|
||
|
||
1. 基于[在 Linux 上安装 KubeSphere](../../installing-on-linux/introduction/multioverview/) 的教程,您需要创建一个默认文件 `config-sample.yaml`。执行以下命令修改该文件:
|
||
|
||
```bash
|
||
vi config-sample.yaml
|
||
```
|
||
|
||
{{< notice note >}}
|
||
如果您采用 [All-in-One 安装](../../quick-start/all-in-one-on-linux/),则不需要创建 `config-sample.yaml` 文件,因为可以直接创建集群。一般来说,All-in-One 模式是为那些刚接触 KubeSphere 并希望熟悉系统的用户而准备的,如果您想在该模式下启用审计日志(例如用于测试),请参考[下面的部分](#在安装后启用审计日志),查看如何在安装后启用审计功能。
|
||
{{</ notice >}}
|
||
|
||
2. 在该文件中,搜寻到 `auditing`,并将 `enabled` 的 `false` 改为 `true`。完成后保存文件。
|
||
|
||
```yaml
|
||
auditing:
|
||
enabled: true # 将“false”更改为“true”。
|
||
```
|
||
|
||
{{< notice note >}}
|
||
默认情况下,如果启用了审计功能,KubeKey 将安装内置 Elasticsearch。对于生产环境,如果您想启用审计功能,强烈建议在 `config-sample.yaml` 中设置以下值,尤其是 `externalElasticsearchUrl` 和 `externalElasticsearchPort`。在安装前提供以下信息后,KubeKey 将直接对接您的外部 Elasticsearch,不再安装内置 Elasticsearch。
|
||
{{</ notice >}}
|
||
|
||
```yaml
|
||
es: # Storage backend for logging, tracing, events and auditing.
|
||
elasticsearchMasterReplicas: 1 # The total number of master nodes. Even numbers are not allowed.
|
||
elasticsearchDataReplicas: 1 # The total number of data nodes.
|
||
elasticsearchMasterVolumeSize: 4Gi # The volume size of Elasticsearch master nodes.
|
||
elasticsearchDataVolumeSize: 20Gi # The volume size of Elasticsearch data nodes.
|
||
logMaxAge: 7 # Log retention day in built-in Elasticsearch. It is 7 days by default.
|
||
elkPrefix: logstash # The string making up index names. The index name will be formatted as ks-<elk_prefix>-log.
|
||
externalElasticsearchUrl: # The URL of external Elasticsearch.
|
||
externalElasticsearchPort: # The port of external Elasticsearch.
|
||
```
|
||
|
||
3. 使用该配置文件创建集群:
|
||
|
||
```bash
|
||
./kk create cluster -f config-sample.yaml
|
||
```
|
||
|
||
### 在 Kubernetes 上安装
|
||
|
||
在 Kubernetes 上安装 KubeSphere 的过程与教程[在 Kubernetes 上安装 KubeSphere](../../installing-on-kubernetes/introduction/overview/) 中的说明大致相同,不同之处是需要先在 [cluster-configuration.yaml](https://github.com/kubesphere/ks-installer/releases/download/v3.1.1/cluster-configuration.yaml) 文件中启用审计功能(可选组件)。
|
||
|
||
1. 下载 [cluster-configuration.yaml](https://github.com/kubesphere/ks-installer/releases/download/v3.1.1/cluster-configuration.yaml) 文件,然后打开并开始编辑。
|
||
|
||
```bash
|
||
vi cluster-configuration.yaml
|
||
```
|
||
|
||
2. 在该本地 `cluster-configuration.yaml` 文件中,搜寻到 `auditing`,并将 `enabled` 的 `false` 改为 `true`。完成后保存文件。
|
||
|
||
```yaml
|
||
auditing:
|
||
enabled: true # 将“false”更改为“true”。
|
||
```
|
||
|
||
{{< notice note >}}
|
||
默认情况下,如果启用了审计功能,ks-installer 会安装内置 Elasticsearch。对于生产环境,如果您想启用审计功能,强烈建议在 `cluster-configuration.yaml` 中设置以下值,尤其是 `externalElasticsearchUrl` 和 `externalElasticsearchPort`。在安装前提供以下信息后,ks-installer 将直接对接您的外部 Elasticsearch,不再安装内置 Elasticsearch。
|
||
{{</ notice >}}
|
||
|
||
```yaml
|
||
es: # Storage backend for logging, tracing, events and auditing.
|
||
elasticsearchMasterReplicas: 1 # The total number of master nodes. Even numbers are not allowed.
|
||
elasticsearchDataReplicas: 1 # The total number of data nodes.
|
||
elasticsearchMasterVolumeSize: 4Gi # The volume size of Elasticsearch master nodes.
|
||
elasticsearchDataVolumeSize: 20Gi # The volume size of Elasticsearch data nodes.
|
||
logMaxAge: 7 # Log retention day in built-in Elasticsearch. It is 7 days by default.
|
||
elkPrefix: logstash # The string making up index names. The index name will be formatted as ks-<elk_prefix>-log.
|
||
externalElasticsearchUrl: # The URL of external Elasticsearch.
|
||
externalElasticsearchPort: # The port of external Elasticsearch.
|
||
```
|
||
|
||
3. 执行以下命令开始安装:
|
||
|
||
```bash
|
||
kubectl apply -f https://github.com/kubesphere/ks-installer/releases/download/v3.1.1/kubesphere-installer.yaml
|
||
|
||
kubectl apply -f cluster-configuration.yaml
|
||
```
|
||
|
||
## 在安装后启用审计日志
|
||
|
||
1. 以 `admin` 身份登录控制台。点击左上角的**平台管理**,选择**集群管理**。
|
||
|
||
2. 点击 **CRD**,在搜索栏中输入 `clusterconfiguration`,点击搜索结果查看其详细页面。
|
||
|
||
{{< notice info >}}
|
||
定制资源定义 (CRD) 允许用户在不新增 API 服务器的情况下创建一种新的资源类型,用户可以像使用其他 Kubernetes 原生对象一样使用这些自定义资源。
|
||
{{</ notice >}}
|
||
|
||
3. 在**资源列表**中,点击 `ks-installer` 右侧的 <img src="/images/docs/zh-cn/enable-pluggable-components/kubesphere-auditing-logs/three-dots.png" height="20px">,选择**编辑配置文件**。
|
||
|
||
4. 在该 YAML 文件中,搜寻到 `auditing`,将 `enabled` 的 `false` 改为 `true`。完成后,点击右下角的**确定**,保存配置。
|
||
|
||
```yaml
|
||
auditing:
|
||
enabled: true # 将“false”更改为“true”。
|
||
```
|
||
|
||
{{< notice note >}}
|
||
默认情况下,如果启用了审计功能,将安装内置 Elasticsearch。对于生产环境,如果您想启用审计功能,强烈建议在该 YAML 文件中设置以下值,尤其是 `externalElasticsearchUrl` 和 `externalElasticsearchPort`。提供以下信息后,KubeSphere 将直接对接您的外部 Elasticsearch,不再安装内置 Elasticsearch。

|
||
|

```yaml
|
||

|
||
elasticsearchMasterReplicas: 1 # The total number of master nodes. Even numbers are not allowed.
|
||
elasticsearchDataReplicas: 1 # The total number of data nodes.
|
||
elasticsearchMasterVolumeSize: 4Gi # The volume size of Elasticsearch master nodes.
|
||
elasticsearchDataVolumeSize: 20Gi # The volume size of Elasticsearch data nodes.
|
||
logMaxAge: 7 # Log retention day in built-in Elasticsearch. It is 7 days by default.
|
||
elkPrefix: logstash # The string making up index names. The index name will be formatted as ks-<elk_prefix>-log.
|
||
externalElasticsearchUrl: # The URL of external Elasticsearch.
|
||
externalElasticsearchPort: # The port of external Elasticsearch.
|
||
```
|
||
|
||
5. 可以执行以下命令,使用 Web Kubectl 工具来检查安装过程:
|
||
|
||
```bash
|
||
kubectl logs -n kubesphere-system $(kubectl get pod -n kubesphere-system -l app=ks-install -o jsonpath='{.items[0].metadata.name}') -f
|
||
```
|
||
|
||
{{< notice note >}}
|
||
|
||
您可以点击控制台右下角的 <img src="/images/docs/zh-cn/enable-pluggable-components/kubesphere-auditing-logs/hammer.png" height="20px"> 找到 Web Kubectl 工具。

## 验证组件的安装
|
||
|
||
{{< tabs >}}
|
||
|
||
{{< tab "在仪表板中验证组件的安装" >}}
|
||
|
||
验证您可以使用右下角**工具箱**中的**操作审计**功能。
|
||
|
||
{{</ tab >}}
|
||
|
||
{{< tab "通过 kubectl 验证组件的安装" >}}
|
||
|
||
执行以下命令来检查 Pod 的状态:
|
||
|
||
```bash
|
||
kubectl get pod -n kubesphere-logging-system
|
||
```
|
||
|
||
如果组件运行成功,输出结果如下:
