Modifying the Dede system database table prefix

1, the modification before we back up the data (the man did not backup, I 艹, hurt), the operation of the backup process is: The site------system------Database backup/restore-------and then press submit. The default saved data is in the Data/backupdata directory.

2, then modify the directory under the Data/backupdata directory of all the TXT file table prefix, the Dede_ to modify the table prefix you need. As I was the table prefix modified into xl_.

3, immediately after opening all txt files in the Data/backupdata directory, replace the Dede_ table prefix in the file, Xl_ (Open with DW, batch replace it)

4, finally modify the data directory under the common.inc.php file, find $cfg _dbprefix = ' Dede_ '; Modify the Dede_ to Xl_.

5,--------System--------Database backup/restore--------data restore--------start restoring data.

Dude, fiddling with the website, be sure to remember the backup ... I 艹

In addition, the DEDECMS system after the move or after the System Restore, re-update the column or file, sometimes there will be such an error message: No column data may cache files (data/cache/inc_catalog_base.inc) No update please check for write permission

At this time everyone to change the file or folder Write permissions, generally will go to change to 777 or 755, but in fact this does not work. In fact, the solution is very simple, as long as the following three steps, you can

1. Delete the Inc_catalog_base.inc cache file

2. Update the system cache, click "Generate-Update system cache-and start execution" is OK.

3. Then regenerate the column, there will be no error message.
