我在部署ghost是,日志中报错说连接不上数据库,但是我确实检查过,在worker节点上确保能够连接上数据库的,但是启动容器不成功,任然报错说链接不上数据库。并且我不能够进入容器中去测试,[root@k8s-master-01 ghost]# kubectl logs -n ghost pod/ghost-559688f9f5-9s7hk [2025-10-09 06:13:14] INFO Ghost is running in production...

当部署 Ghost 时容器启动失败,日志显示连接数据库报错 “Access denied for user 'ghost_user'@'192.168.161.21' (using password: YES)”,而在 worker 节点能连接数据库,可尝试以下方法解决: #### 1. 检查数据库用户权限 要保证 `ghost_user` 用户具备从 Ghost 容器所在 IP 地址(即 `192.168.161.21`)连接数据库的权限。以 MySQL 为例,可以使用以下 SQL 语句为用户授予权限: ```sql GRANT ALL PRIVILEGES ON ghostdb.* TO 'ghost_user'@'192.168.161.21' IDENTIFIED BY 'your_password'; FLUSH PRIVILEGES; ``` 上述代码中,`ghostdb` 是 Ghost 使用的数据库名,`your_password` 是 `ghost_user` 的密码。 #### 2. 检查密码是否正确 确认 Ghost 容器配置的数据库密码与数据库中 `ghost_user` 的密码一致。可以查看 Ghost 容器的环境变量配置,比如在 Kubernetes 的 Deployment 文件中: ```yaml apiVersion: apps/v1 kind: Deployment metadata: name: ghost-deployment spec: replicas: 1 selector: matchLabels: app: ghost template: metadata: labels: app: ghost spec: containers: - name: ghost image: ghost:latest ports: - containerPort: 2368 env: - name: database__client value: mysql - name: database__connection__host value: mysql-service - name: database__connection__user value: ghost_user - name: database__connection__password value: your_password - name: database__connection__database value: ghostdb ``` 确保 `database__connection__password` 的值是正确的。 #### 3. 检查网络连通性 虽然 worker 节点能连接数据库,但要确保 Ghost 容器和数据库之间的网络是连通的。可以在 Ghost 容器内尝试使用 `ping` 和 `telnet` 命令测试连通性: ```bash kubectl exec -it <ghost-pod-name> -- ping <database-service-ip> kubectl exec -it <ghost-pod-name> -- telnet <database-service-ip> <database-port> ``` 其中,`<ghost-pod-name>` 是 Ghost 容器所在的 Pod 名称,`<database-service-ip>` 是数据库服务的 IP 地址,`<database-port>` 是数据库服务的端口号(MySQL 默认是 3306)。 #### 4. 检查数据库服务状态 确保数据库服务正常运行,没有出现异常。可以查看数据库服务的日志,检查是否有报错信息。 #### 5. 检查防火墙设置 确认防火墙没有阻止 Ghost 容器和数据库之间的通信。可以检查防火墙规则,开放数据库服务的端口(如 MySQL 的 3306 端口)。
