The GD library is turned on Via Phpinfo (), but there is no freetype and JPEG support but PNG support

It is estimated that freetype and JPEG are not installed

So the two software is installed

Yum Install freetype*

Yum Install libjpeg*

After the installation, find out where the library is installed.

Find/-name FreeType

Results in the/usr/include/freetype2/folder

Empathy Libjpeg in the/usr/include

Then enter the PHP source code of the PHP source code (downloaded code)/EXT/GD folder in the use of phpize to expand the installation

(My PHP is installed in/usr/local/php)

/usr/local/php/bin/phpize

./configure--with-freetype-dir=/usr/include/freetype2--with-jpeg-dir=/usr/include--with-php-config=/usr/local/ Php/bin/php-config

And then

Make

Make install

This completes the GD library in PHP to recompile

Reboot the Apache service issue to a successful resolution
