教你给数据库设置交叉权限
由于 SupeSite 需要调用 Discuz! 和 UCHome 的数据,所以如果它们不安装在同一个数据库,SupeSite 的数据库用户必须要对 Discuz! 和 UCHome 的数据库有读
由于 SupeSite 需要调用 Discuz! 和 UCHome 的数据,所以如果它们不安装在同一个数据库,SupeSite 的数据库用户必须要对 Discuz! 和 UCHome 的数据库有读取、修改、删除等权限。这就需要在 MySQL 中对用户权限进行修改,授予需要的权限。
本文将演示这种情况,并给出详细的解决步骤。
本文示例的配置如下:
Discuz!
数据库名:discuz_7_sc_utf8
数据库用户名:discuz_mysql
权限:操作 discuz_7_sc_utf8 的全部权限
SupeSite/X-space
数据库名:ss_601_xs_401_sc_utf8
数据库用户名:ss_mysql
权限:操作 ss_mysql 的全部权限
出现情况:安装 SupeSite/X-space 时无法检测到 Discuz! 的数据库。
解决方法:授予 ss_mysql 操作 discuz_7_sc_utf8 的全部权限。
如果为了方便,可以创建一个数据库用户,授予该用户操作 Discuz! 和 SupeSite 数据库的全部权限,在安装时,都使用这个数据库用户,就不会出现本文的这种情况。以后安装别的产品,比如 UCenter Home,再授予该用户操作 UCenter Home 数据库的权限即可。
一、安装 Discuz_7.0.0_SC_UTF8
1、在 MySQL 中创建数据库 discuz_7_sc_utf8
打开 phpMyAdmin => 创建一个新的数据库
2、在 MySQL 中创建数据库用户 discuz_mysql,授予操作数据库 discuz_7_sc_utf8 的权限
打开 phpMyAdmin => 权限 => 添加新用户
为了安全,不授予 discuz_mysql 这个用户访问其他数据库的权利,所以全局权限不选。设计完毕,点击“执行”。
跳转到“编辑权限”的页面,“按数据库指定权限”选择“discuz_7_sc_utf8”
在这里,授予数据库用户 discuz_mysql 操作数据库 discuz_7_sc_utf8 的全部权限,如图所示。
3、Discuz_7.0.0_SC_UTF8 的安装设置
在 Discuz! 安装时,输入刚才创建的数据库名、用户名和密码。
二、安装 SupeSite6.0.1_X-Space4.0.1_UC_SC_UTF8
1、在 MySQL 中创建数据库 ss_601_xs_401_sc_utf8
2、在 MySQL 中创建数据库用户 ss_mysql,授予操作数据库 ss_601_xs_401_sc_utf8 的权限
3、SupeSite6.0.1_X-Space4.0.1_UC_SC_UTF8 的安装设置
安装 SuperSite 时,输入刚才创建的数据库名:ss_601_xs_401_sc_utf8,数据库用户名:ss_mysql,以及已安装的论坛 Discuz 的数据库名 discuz_7_sc_utf8,如图所示。
因为刚才只是授予数据库用户 ss_mysql 操作数据库 ss_601_xs_401_sc_utf8 的权限,所以数据库用户 ss_mysql 并没有操作数据库 discuz_7_sc_utf8 的权限,这安装时出现错误,,提示“发生错误,您指定的 Discuz!数据库(discuz_7_sc_utf8)不存在,请修正”。
4、授予用户 ss_mysql 操作数据库 discuz_7_sc_utf8 的权限,安装成功
出现这种情况,就需要授予 ss_mysql 操作数据库 discuz_7_sc_utf8 的权限。打开 phpMyAdmin => 权限 => 编辑权限,如图所示。
SupeSite 需要 读取、插入、删除数据库 discuz_7_sc_utf8 中的数据,所以授予用户 ss_mysql 操作数据库 discuz_7_sc_utf8 的全部权限。
授予权限之后,通过安装程序的检测,可以继续安装了。
需要注意的是,如果希望 SupeSite 和 Discuz!同步登录,SupeSite 的 Cookie 设置要和 Discuz! 目录下 config.inc.php 文件中的值相同,如图所示。
现在安装完毕,SupeSite 和 X-space 能够正常显示论坛中的内容。

Apple's latest releases of iOS18, iPadOS18 and macOS Sequoia systems have added an important feature to the Photos application, designed to help users easily recover photos and videos lost or damaged due to various reasons. The new feature introduces an album called "Recovered" in the Tools section of the Photos app that will automatically appear when a user has pictures or videos on their device that are not part of their photo library. The emergence of the "Recovered" album provides a solution for photos and videos lost due to database corruption, the camera application not saving to the photo library correctly, or a third-party application managing the photo library.

JSON data can be saved into a MySQL database by using the gjson library or the json.Unmarshal function. The gjson library provides convenience methods to parse JSON fields, and the json.Unmarshal function requires a target type pointer to unmarshal JSON data. Both methods require preparing SQL statements and performing insert operations to persist the data into the database.

Using the database callback function in Golang can achieve: executing custom code after the specified database operation is completed. Add custom behavior through separate functions without writing additional code. Callback functions are available for insert, update, delete, and query operations. You must use the sql.Exec, sql.QueryRow, or sql.Query function to use the callback function.

MySQL is an open source relational database management system. 1) Create database and tables: Use the CREATEDATABASE and CREATETABLE commands. 2) Basic operations: INSERT, UPDATE, DELETE and SELECT. 3) Advanced operations: JOIN, subquery and transaction processing. 4) Debugging skills: Check syntax, data type and permissions. 5) Optimization suggestions: Use indexes, avoid SELECT* and use transactions.
