+# Datasource Setting
+
+## Standalone Switching Metadata Database Configuration
+
+We here use MySQL as an example to illustrate how to configure an external database:
+
+* First of all, follow the instructions in [datasource-setting](datasource-setting.md) `Pseudo-Cluster/Cluster Initialize the Database` section to create and initialize database
+* Set the following environment variables in your terminal or modify the `bin/env/dolphinscheduler_env.sh` with your database username and password for `{user}` and `{password}`:
+
+```shell
+export DATABASE=mysql
+export SPRING_PROFILES_ACTIVE=${DATABASE}
+export SPRING_DATASOURCE_USERNAME={user}
+export SPRING_DATASOURCE_PASSWORD={password}
+```
+
+* Add mysql-connector-java driver to `./standalone-server/libs/standalone-server/`, see [general-setting](general-setting.md) `Pseudo-Cluster/Cluster Initialize the Database` section about where to download
+* Start standalone-server, now you are using mysql as database and it will not clear up your data when you stop or restart standalone-server.
+
+## Pseudo-Cluster/Cluster Initialize the Database
+
+DolphinScheduler metadata is stored in the relational database. Currently, supports PostgreSQL and MySQL. If you use MySQL, you need to manually download [mysql-connector-java driver][mysql] (8.0.16) and move it to the libs directory of DolphinScheduler
+which is `api-server/libs/` and `alert-server/libs` and `master-server/libs` and `worker-server/libs`. Let's take MySQL as an example for how to initialize the database:
+
+For mysql 5.6 / 5.7
+
+```shell
+mysql -uroot -p
+
+mysql> CREATE DATABASE dolphinscheduler DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
+
+# Replace {user} and {password} with your username and password
+mysql> GRANT ALL PRIVILEGES ON dolphinscheduler.* TO '{user}'@'%' IDENTIFIED BY '{password}';
+mysql> GRANT ALL PRIVILEGES ON dolphinscheduler.* TO '{user}'@'localhost' IDENTIFIED BY '{password}';
+
+mysql> flush privileges;
+```
+
+For mysql 8:
+
+```shell
+mysql -uroot -p
+
+mysql> CREATE DATABASE dolphinscheduler DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
+
+# Replace {user} and {password} with your username and password
+mysql> CREATE USER '{user}'@'%' IDENTIFIED BY '{password}';
+mysql> GRANT ALL PRIVILEGES ON dolphinscheduler.* TO '{user}'@'%';
+mysql> CREATE USER '{user}'@'localhost' IDENTIFIED BY '{password}';
+mysql> GRANT ALL PRIVILEGES ON dolphinscheduler.* TO '{user}'@'localhost';
+mysql> FLUSH PRIVILEGES;
+``` 
+
+Then, modify `./bin/env/dolphinscheduler_env.sh` to use mysql, change {user} and {password} to what you set in the previous step.
+
+```shell
+export DATABASE=${DATABASE:-mysql}
+export SPRING_PROFILES_ACTIVE=${DATABASE}
+export SPRING_DATASOURCE_URL="jdbc:mysql://127.0.0.1:3306/dolphinscheduler?useUnicode=true&characterEncoding=UTF-8&useSSL=false"
+export SPRING_DATASOURCE_USERNAME={user}
+export SPRING_DATASOURCE_PASSWORD={password}
+```
+
+After the above steps done you would create a new database for DolphinScheduler, then run the Shell script to init database:
+
+```shell
+sh tools/bin/upgrade-schema.sh
+```
+
+## DataSource Center
+
+DataSource supports MySQL, PostgreSQL, Hive/Impala, Spark, ClickHouse, Oracle, SQL Server and other DataSources.
+
+- Click bottom `Data Source Center -> Create Data Source` to create a new datasource.
+- Click `Test Connection` to test whether the DataSource can connect successfully (datasource can be saved only if it passes the connection test).

+## Standalone 切换元数据库
+
+我们这里以 MySQL 为例来说明如何配置外部数据库：
+
+* 首先，参照 [数据源配置](datasource-setting.md) `伪分布式/分布式安装初始化数据库` 创建并初始化数据库
+* 在你的命令行或者修改 bin/env/dolphinscheduler_env.sh 设定下列环境变量，将 `{user}` 和 `{password}` 改为你数据库的用户名和密码
+
+```shell
+export DATABASE=mysql
+export SPRING_PROFILES_ACTIVE=${DATABASE}
+export SPRING_DATASOURCE_USERNAME={user}
+export SPRING_DATASOURCE_PASSWORD={password}
+```
+
+* 将mysql-connector-java驱动加到`./standalone-server/libs/standalone-server/`目录下, 下载方法见 [数据源配置](datasource-setting.md) `伪分布式/分布式安装初始化数据库` 一栏
+* 启动standalone-server，此时你已经连接上mysql，重启或者停止standalone-server并不会清空您数据库里的数据
+
+## 伪分布式/分布式安装初始化数据库
+
+DolphinScheduler 元数据存储在关系型数据库中，目前支持 PostgreSQL 和 MySQL，如果使用 MySQL 则需要手动下载 [mysql-connector-java 驱动][mysql] (8.0.16) 并移动到 DolphinScheduler 的每个模块的 libs 目录下
+其中包括 `api-server/libs/` 和 `alert-server/libs` 和 `master-server/libs` 和 `worker-server/libs`。下面以 MySQL 为例，说明如何初始化数据库
+
+对于mysql 5.6 / 5.7：
+
+```shell
+mysql -uroot -p
+
+mysql> CREATE DATABASE dolphinscheduler DEFAULT CHARACTER SET utf8 DEFAULT COLLATE utf8_general_ci;
+
+# 修改 {user} 和 {password} 为你希望的用户名和密码

 ## 配置数据库
 
 Standalone server 使用 H2 数据库作为其元数据存储数据，这是为了上手简单，用户在启动服务器之前不需要启动数据库。但是如果用户想将元数据库存储在
-MySQL 或 PostgreSQL 等其他数据库中，他们必须更改一些配置。我们这里以 MySQL 为例来说明如何配置外部数据库：
-
-* 首先，参照 [伪集群部署](pseudo-cluster.md) `初始化数据库` 创建并初始化数据库 
-* 在你的命令行设定下列环境变量，将 `{user}` 和 `{password}` 改为你数据库的用户名和密码
-
-```shell
-export DATABASE=${DATABASE:-mysql}
-export SPRING_PROFILES_ACTIVE=${DATABASE}
-export SPRING_DATASOURCE_USERNAME={user}
-export SPRING_DATASOURCE_PASSWORD={password}
-```
-
-* 将mysql-connector-java驱动加到`./standalone-server/libs/standalone-server/`目录下, 下载方法见 [伪集群部署](pseudo-cluster.md) `初始化数据库` 一栏
-* 启动standalone-server，此时你已经连接上mysql，重启或者停止standalone-server并不会清空您数据库里的数据
+MySQL 或 PostgreSQL 等其他数据库中，他们必须更改一些配置。请参考 [数据源配置](../howto/datasource-setting.md) `Standalone 切换元数据库` 创建并初始化数据库
