PHP安装JPEG

GD库默认不安装JPEG扩展

安装JPEG

cd /usr/local/srctar -xvf jpegsrc.v9a.tar.gzcd jpeg-9a./configure --prefix=/usr/local/jpeg --enable-sharedmakemake install

安装好的文件存放在 /usr/local/jpeg/lib下

重新编译php

cd /usr/local/src/php-5.5.34./configure --prefix=/usr/local/php5 --with-config-file-path=/usr/local/php5/etc --with-gd --with-iconv --with-zlib --enable-xml --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curlwrappers --enable-mbregex --enable-fpm --enable-mbstring --enable-ftp --enable-gd-native-ttf --with-openssl --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --with-pear --with-gettext --enable-session --with-mcrypt --with-curl --with-jpeg-dir=/usr/local/jpeg --with-freetype-dir=/usr/include/freetype2/freetypemakemake install

进入php安装包对应的gd扩展里面进行重新编译

cd /usr/local/src/php-5.5.34/ext/gd//usr/local/php5/bin/phpize./configure --with-php-config=/usr/local/php5/bin/php-config --with-jpeg-dir=/usr/local/jpegmake && make install

会生成如下内容

Libraries have been installed in:   /usr/local/src/php-5.5.34/ext/gd/modulesInstalling shared extensions:          /usr/local/php5/lib/php/extensions/no-debug-non-zts-20121212/Installing header files:          /usr/local/php5/include/php/

为了方便，把.so文件集中放置

mv /usr/local/php5/lib/php/extensions/no-debug-non-zts-20121212/gd.so /usr/local/php5/lib/php/extensions/

修改php.ini文件

找到 ;extension_dir = “./”这一行，去掉注释，并修改路径。extension_dir = "/usr/local/php5/lib/php/extensions/"extension=gd.so

重启php服务器

service php-fpm reload
