linux下php5源码编译安装实践
php5源码编译安装，以及一些组件的安装：

a.安装 jpeg7
# tar -zvxf jpegsrc.v7b.tar.gz
# cd jpeg-7b
# ./configure --prefix=/usr/local/jpeg7/ --enable-shared --enable-static
# make; make install

b.安装libpng
# tar -zvxf libpng-1.2.8-config.tar.gz
# cd libpng-1.2.8
# cp scripts/makefile.std makefile
# make; make install

c.安装 freetype
http://sourceforge.net/projects/freetype/files/
# tar -zvxf freetype-2.1.10.tar.gz
# cd freetype-2.1.10
# mkdir -p /usr/local/freetype
# ./configure --prefix=/usr/local/freetype
# make;make install

d.:安装zlib
#tar -zxvf zlib-1.2.3.tar.gz
#cd zlib.1.2.3
# ./configure --prefix=/usr/local/zlib
# make;make install

e.安装GD库
http://download.chinaunix.net/download.php?id=6665&ResourceID=3479
# tar -zvxf gd-2.0.33.tar.gz
# mkdir -p /usr/local/gd2
# cd gd-2.0.33
# ./configure --prefix=/usr/local/gd2 --with-jpeg=/usr/local/jpeg7/
--with-png=/usr/local/lib/
--with-zlib=/usr/local/zlib/
--with-freetype=/usr/local/freetype/
# make; make install
编译过程中如果出现relocation R_X86_64_32 can not be used when making a shared object; recompile with -fPIC,请按照提示找到 CFLAGS  后边加上 -fPIC

f.libmcrypt模块安装

wget http://downloads.sourceforge.net/project/mcrypt/Libmcrypt/2.5.8/libmcrypt-2.5.8.tar.gz?r=http%3A%2F
tar zxvf libmcrypt-2.5.8.tar.gz
# cd libmcrypt-2.5.8
# ./configure && make && make install
# cd libltdl
# ./configure --enable-ltdl-install && make && make install

g.安装mhash
     #tar -zxvf mhash-0.9.9.9.tar.gz
     #cd mhash-0.9.9.9
     #./configure
     #make
     #make install

h.安装mcrypt
     #tar -zxvf mcrypt-2.6.8.tar.gz
      #cd mcrypt-2.6.8
      #LD_LIBRARY_PATH=/usr/local ./configure
      #make
      #make install

f.安装php
＃LIBS='-lresolv' ./configure -prefix=/usr/local/php --with-apxs2=/usr/sbin/apxs  --with-mysql=/usr/local/mysql  --with-pdo-mysql=/usr/local/mysql --without-pear -with-gd=/usr/local/gd2/ --with-jpeg-dir=/usr/local/jpeg7/ --with-zlib-dir=/usr/local/zlib/ --with-png-dir=/usr/local/lib/ --with-freetype-dir=/usr/local/freetype/ --enable-mbstring  --with-mcrypt --with-mhash

＃make && make install

最后拷贝php源码目录的php.ini-* 到 /etc/php.ini，重启apache

用源码独立编译php的extension库

比如增加mbstring,切换到php源码的ext文件下
cd mbtring
/usr/local/php5/bin/phpize //生成configure编译文件
编译mbstring.so库文件
./configure  --with-php-config=/usr/local/php5/bin/php-config --enable-mbstring 
make && make install 
修改php.ini文件,指定
extension_dir=/usr/local/php5/lib/php/extensions/no-debug-non-zts-20090626/
extension = mbstring.so

重新启动apache

PHP编译支持mysqli
前提是必须安装mysql

直接上命令

先进入源码包我的源码包是在

/usr/local/php-5.2.1/ext/mysqli

这样进入 cd /usr/local/php-5.2.1/ext/mysqli

然后执行

/usr/local/php/bin/phpize

这条命令是生成configure
