How to Make php in GD

For more information about how to use php in GD-Linux Enterprise Application-Linux server application, see the following. I installed fc6 and apache mysql php, all of which are installed by default with the rpm of the CD. I want php to support GD, so, I installed the following rpm package again:
Freetype-2.2.1-10.fc6.rpm
Libjpeg-6b-37.rpm
LibXpm-3.5.5-3.rpm
Libpng-1.2.10-7.rpm
Freetype-2.2.1-10.fc6.rpm
Gd-2.0.33-9.3.fc6.rpm

However, I used phpinfo () for testing and found no GD support information.
On the Internet, you need to set the php. ini file to load the GD extension. Most of them are about windows.
How to set the php. ini file to support the GD extension installed by default in the rpm package?
Thank you. I am a newbie. The more detailed the lecture, the better.

In addition, I installed linux without the x system and used vi to view the php. ini file. However, this file is so long that one row and one row are too tired to read. Does vi have a search function? You can quickly locate the content you are looking for, such as the word "extensions, the graphical tool gedit is much easier!


Thank you again for your help. I wish you a safe life!
