 ## 数据库准备
 
-本服务的部分模块依赖外部数据源 `jianshu` 和 `jpep` 数据库，您需事先下载并进行导入。

-创建用户：

-```sql
-CREATE ROLE jtools LOGIN PASSWORD 'jtools';
-```
-
-创建数据库：
-
-```sql
-CREATE DATABASE jtools WITH OWNER = jtools;
-CREATE DATABASE logs;
-```
-
-创建扩展：
-

-
-```sql
-CREATE EXTENSION IF NOT EXISTS pg_trgm;

-
-```sql
-GRANT SELECT ON TABLE ftn_macket_records TO jtools;
-GRANT SELECT ON TABLE ftn_orders TO jtools;
+```shell
+cd sql
 ```
 
-创建索引：
+如果您需要修改数据库用户名和密码，请修改 `sql` 目录下的 `0.sql` 和每个子目录下的 `0.sql` 文件。
 
-（`jianshu` 数据库）
+您需要一个具有创建用户和数据库权限的用户（一般是超级用户）来完成数据库准备。
 
-```sql
-CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_article_earning_ranking_records_ranking ON article_earning_ranking_records (ranking);
+每个目录中的 SQL 脚本均应按照编号顺序执行。
 
-CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_lottery_win_records_time ON lottery_win_records (time);
-CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_lottery_win_records_user_slug ON lottery_win_records (user_slug);
-CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_lottery_win_records_award_name ON lottery_win_records (award_name);
+首先，执行 `sql` 目录下的脚本。
 
-CREATE INDEX CONCURRENTLY IF NOT EXISTS idx_users_name ON users USING gin (name gin_trgm_ops);
-```
+依次切换到与 `sql` 下的子目录（数据库目录）名称相同的数据库中，先执行每个表目录中的 SQL 脚本，再执行数据库目录下的 SQL 脚本。
