+# Tutorial on modifying database parameters with yaml
+
+Some parameters of the database cannot take effect immediately after modification. Therefore, you need to apply yaml to modify parameters and restart the database. Modifying parameters in yaml will cause the database to **restart**, and the whole process will take about **20 seconds**. The following uses the **Postgres** database as an example to modify parameters:
+
+1. **Access the terminal**：
+
+![config_1](./imgs/config_1.png)
+
+2. **Edit pg-config.yaml**：
+
+```bash
+$ vim pg-config.yaml
+```
+![config_2](./imgs/config_2.png)
+
+3. **Copy yaml to pg-config.yaml and save pg-config.yaml**：
+
+![config_3](./imgs/config_3.png)
+```yaml
+apiVersion: apps.kubeblocks.io/v1alpha1
+kind: OpsRequest
+metadata:
+  name: test
+spec:
+  clusterRef: test-pg  #Change the database name to your own
+  reconfigure:
+    componentName: postgresql
+    configurations: #The following configuration is for reference only. You only need to keep the part to be modified and modify the corresponding parameter values
+      - keys:
+          - key: postgresql.conf
+            parameters:
+              - key: max_connections #Sets the maximum number of simultaneous connections that can be made to the database
+                value: "1000"
+        name: postgresql-configuration
+  ttlSecondsAfterSucceed: 0

+# 通过yaml修改数据库参数教程
+
+由于数据库的某些参数在修改后无法立即生效，因此需要通过应用yaml来实现修改参数并重启数据库通过yaml修改参数会导致数据库**重启**，整个过程大概会持续**20s**左右。这里以**Postgres**数据库的参数修改为例，具体操作步骤如下：
+1. **进入终端**：
+
+![config_1](./imgs/config_1.png)
+
+2. **编辑pg-config.yaml**：
+
+```bash
+$ vim pg-config.yaml
+```
+![config_2](./imgs/config_2.png)
+
+3. **复制yaml到pg-config.yaml中，保存pg-config.yaml**：
+

+  clusterRef: test-pg  #修改为自己的数据库名
+  reconfigure:
+    componentName: postgresql
+    configurations: #以下配置仅供参考，只需保留要修改的部分即可，并修改对应的参数的值
+      - keys:
+          - key: postgresql.conf
+            parameters:
+              - key: max_connections #设置可以同时与数据库建立的最大连接数

+$ kubectl get OpsRequest

+```
+![config_5](./imgs/config_5.png)
+
+6. **进入数据库查看配置是否生效**：
+```bash
+$ show max_connections;
+```
