TAR-ZXVF jpegsrc.v8b.tar.gz
CD jpeg-8b

./configure--prefix=/usr/local/jpeg--enable-shared--enable-static
Make && make install

Below to enter the PHP source directory under the ext of the GD directory

After entering the GD directory, note that the following/usr/local/php/is the installation path of your server PHP. Mine is the way it's written.

/usr/local/php/bin/phpize

./configure--with-php-config=/usr/local/php/bin/php-config--with-jpeg-dir=/usr/local/jpeg/

Make && make install

After executing these systems, you will be prompted to gd.so the build directory

After adding gd.so under PHP.ini, restart the PHP restart Application server and it will be OK.

Some machines may not work, so solve

Yum Install Libjpeg-devel freetype-devel libpng-devel
Make clean and then re-/configure
Make&make Install

See Phpinfo OK.
