linux环境下php GD库的安装

1.安装zlib

tar zxvf zlib-1.2.2.tar.gz

cd zlib-1.2.2

./configure

make

make install

2.安装libpng

tar zxvf libpng-1.2.7.tar.tar

cd libpng-1.2.7

cd scripts/

mv makefile.linux ../makefile

cd ..

make

make install

注意，这里的makefile不是用./configure生成，而是直接从scripts/里拷一个

3.安装freetype

tar zxvf freetype-2.1.9.tar.gz

cd freetype-2.1.9

./configure

make

make install

4.安装Jpeg

tar zxvf jpegsrc.v6b.tar.gz

cd jpeg-6b/

./configure –enable-shared

make

make test

make install

注意，这里configure一定要带–enable-shared参数，不然，不会生成共享库

5.安装GD

tar zxvf gd-2.0.33.tar.gz

cd gd-2.0.33

./configure –with-png –with-freetype –with-jpeg

make install

6.重新编译PHP

tar zxvf php-5.2.17tar.gz

cd php-5.2.17

./configure (以前的参数) –with-gd –enable-gd-native-ttf –with-zlib –with-png –with-jpeg –with-freetype –enable-sockets

make

make install

然后编辑php.ini，加入extension=gd.so

重启apache就行了

若还是不成功，那就使用终极大招，把yum源切换成阿里的，然后执行

yum install php-mysql php-gd libjpeg* php-imap php-ldap php-odbc php-pear php-xml php-xmlrpc php-mbstring php-mcrypt php-bcmath php-mhash libmcrypt

重启apache
