# 设置配置文件 {#settings-profiles}
|
|
|
|
设置配置文件是以相同名称分组的设置的集合。
|
|
|
|
!!! note "信息"
|
|
ClickHouse还支持 [SQL驱动的工作流](../access-rights.md#access-control) 用于管理设置配置文件。 我们建议使用它。
|
|
|
|
配置文件可以有任何名称。 配置文件可以有任何名称。 您可以为不同的用户指定相同的配置文件。 您可以在设置配置文件中编写的最重要的事情是 `readonly=1`，这确保只读访问。
|
|
|
|
设置配置文件可以彼此继承。 要使用继承，请指示一个或多个 `profile` 配置文件中列出的其他设置之前的设置。 如果在不同的配置文件中定义了一个设置，则使用最新定义。
|
|
|
|
要应用配置文件中的所有设置，请设置 `profile` 设置。
|
|
|
|
示例:
|
|
|
|
安装 `web` 侧写
|
|
|
|
``` sql
|
|
SET profile = 'web'
|
|
```
|
|
|
|
设置配置文件在用户配置文件中声明。 这通常是 `users.xml`.
|
|
|
|
示例:
|
|
|
|
``` xml
|
|
<!-- Settings profiles -->
|
|
<profiles>
|
|
<!-- Default settings -->
|
|
<default>
|
|
<!-- The maximum number of threads when running a single query. -->
|
|
<max_threads>8</max_threads>
|
|
</default>
|
|
|
|
<!-- Settings for quries from the user interface -->
|
|
<web>
|
|
<max_rows_to_read>1000000000</max_rows_to_read>
|
|
<max_bytes_to_read>100000000000</max_bytes_to_read>
|
|
|
|
<max_rows_to_group_by>1000000</max_rows_to_group_by>
|
|
<group_by_overflow_mode>any</group_by_overflow_mode>
|
|
|
|
<max_rows_to_sort>1000000</max_rows_to_sort>
|
|
<max_bytes_to_sort>1000000000</max_bytes_to_sort>
|
|
|
|
<max_result_rows>100000</max_result_rows>
|
|
<max_result_bytes>100000000</max_result_bytes>
|
|
<result_overflow_mode>break</result_overflow_mode>
|
|
|
|
<max_execution_time>600</max_execution_time>
|
|
<min_execution_speed>1000000</min_execution_speed>
|
|
<timeout_before_checking_execution_speed>15</timeout_before_checking_execution_speed>
|
|
|
|
<max_columns_to_read>25</max_columns_to_read>
|
|
<max_temporary_columns>100</max_temporary_columns>
|
|
<max_temporary_non_const_columns>50</max_temporary_non_const_columns>
|
|
|
|
<max_subquery_depth>2</max_subquery_depth>
|
|
<max_pipeline_depth>25</max_pipeline_depth>
|
|
<max_ast_depth>50</max_ast_depth>
|
|
<max_ast_elements>100</max_ast_elements>
|
|
|
|
<readonly>1</readonly>
|
|
</web>
|
|
</profiles>
|
|
```
|
|
|
|
该示例指定了两个配置文件: `default` 和 `web`.
|
|
|
|
该 `default` 配置文件有一个特殊用途：它必须始终存在并在启动服务器时应用。 换句话说， `default` 配置文件包含默认设置。
|
|
|
|
该 `web` 配置文件是一个常规的配置文件，可以使用设置 `SET` 查询或在HTTP查询中使用URL参数。
