Detailed explanation of method examples for setting cross permissions for databases under mysql

Since SupeSite needs to call the data of Discuz! and UCHome, if they are not installed in the same database, the database user of SupeSite must read, modify, Delete and other permissions.

This requires modifying user permissions in MySQL and granting the required permissions.

This article will demonstrate this situation and give detailed solution steps.

The configuration of the example in this article is as follows:

Discuz!
Database name: discuz_7_sc_utf8
Database user name: discuz_mysql
Permissions: full permissions to operate discuz_7_sc_utf8

SupeSite / Unable to detect Discuz!'s database.

Solution: Grant ss_mysql full permissions to operate discuz_7_sc_utf8.

If for convenience, you can create a database user and grant the user all permissions to operate the Discuz! and SupeSite databases. Use this database user during installation, and the situation in this article will not occur. In the future, you can install other products, such as UCenter Home, and then grant the user permission to operate the UCenter Home database.

1. Install Discuz_7.0.0_SC_UTF8

1. Create a database in MySQL

discuz_7_sc_utf8

Open phpMyAdmin => Create a new database

2. Create database user discuz_mysql in MySQL and grant permission to operate database discuz_7_sc_utf8

Open phpMyAdmin => Permissions=> Add new user

For

Security

, the discuz_mysql user is not granted the right to access other databases, so the global permissions are not selected. After the design is completed, click "Execute".

Jump to the "Edit Permissions" page, select "discuz_7_sc_utf8" for "Specify Permissions by Database"

Here, grant the database user discuz_mysql all permissions to operate the database discuz_7_sc_utf8, as shown in the figure.

##3. Installation settings of Discuz_7.0.0_SC_UTF8

When installing Discuz! , enter the database name, username and password you just created.

##2. Install SupeSite6.0.1_X-Space4.0.1_UC_SC_UTF8

1. Create the database ss_601_xs_401_sc_utf8

2. Create database user ss_mysql in MySQL and grant permission to operate database ss_601_xs_401_sc_utf8

##3. Installation settings of SupeSite6.0.1_X-Space4.0.1_UC_SC_UTF8

When installing Super

Site, enter the database name just created: ss_601_xs_401_sc_utf8, database Username: ss_mysql, and the database name of the installed forum Discuz, discuz_7_sc_utf8, as shown in the figure.

Because the database user ss_mysql has just been granted the permission to operate the database ss_601_xs_401_sc_utf8, the database user ss_mysql does not have the permission to operate the database discuz_7_sc_utf8. An error occurred during the installation, prompting "An error occurred. , the Discuz! database (discuz_7_sc_utf8) you specified does not exist, please correct it."

##4. Grant user ss_mysql the permission to operate the database discuz_7_sc_utf8, the installation is successful

appears In this case, you need to grant ss_mysql the permission to operate the database discuz_7_sc_utf8. Open phpMyAdmin => Permissions => Edit permissions, as shown.

SupeSite needs to read, insert, and delete data in the database discuz_7_sc_utf8, so user ss_mysql is granted all permissions to operate the database discuz_7_sc_utf8.

After granting permission, you can continue the installation after passing the installation program's detection.

It should be noted that if you want SupeSite and Discuz! to log in simultaneously, the Cookie setting of SupeSite must be consistent with the config.inc.php in the Discuz! directory. The values ​​in the file are the same as shown.

Now that the installation is complete, SupeSite and X-space can display the content in the forum normally.
