为了解决编译安装php后找不到libphp5.so的问题，搜到了这位大牛写的CentOS 64位系统安装步骤，按照做了一下，编译出的php果然有libphp5.so文件。
先易后难:
1.Mysql (注意,注意,要下载一个64位的mysql)
# wget ://mysql.he.net// //下载
# tar zxvf mysql-5.1.30-linux-x86_64-glibc23.tar.gz //解压
# ln -s mysql-5.1.30-linux-x86_64-glibc23 mysql //链接
# groupadd mysql //增加组
# useradd -g mysql mysql //增加用户
# cd mysql //改变目录
# scripts/mysql_install_db –user=mysql //安装
# chown -R root . //权限
# chown -R mysql data //权限
# chgrp -R mysql . //权限
# bin/mysqld_safe –user=mysql & //第一次运行
# bin/mysqladmin -u root password XXXXXX // 改mysql 的root 密码为 XXXXXX
# cp support-files/mysql.server /etc/rc.d/init.d/mysqld //系统启动时自动运行：
# chkconfig –add mysqld //系统启动时自动运行：
# /etc/rc.d/init.d/mysqld restart //测试一把
// mysql 搞定
2. Apache
没有安装gcc , 先yum install gcc.
# wget //下载
# tar jxvf httpd-2.0.63.tar.bz2 //解压
# cd httpd* //改变目录
# ./configure –prefix=/usr/local/apache –enable-so –enable-rewrite –enable-info –enable-cgid –enable-mime-magic –enable-alias –enable-access –enable-forward //配置
# make //编译
# make install //安装
# /usr/local/apache/bin/apachectl start //第一次运行
3.GD
开始前先建一些目录方便安装(不建目录也可)
mkdir /usr/local/modules
#jpeg目录
mkdir /usr/local/modules/jpeg6
mkdir /usr/local/modules/jpeg6/bin
mkdir /usr/local/modules/jpeg6/lib
mkdir /usr/local/modules/jpeg6/include
mkdir /usr/local/modules/jpeg6/man
mkdir /usr/local/modules/jpeg6/man/man1
a.zlib (看来zlib停止升级了,到现在还是2005年发布的一个东东)
# wget //下载
# tar zxvf zlib-1.2.5.tar.gz //解压
# cd zlib-1.2.5 //改变目录
# CFLAGS=”-O3 -fPIC” ./configure //使用64位 的方法进行编译 (一般只需要./configure)
# make
# make install
b.FreeType
# wget ?modtime=1183336047&big_mirror=0 //下载
# tar zxvf freetype-2.3.5.tar.gz //解压
# cd freetype-2.3.5 //改变目录
# ./configure –prefix=/usr/local/modules/freetype //配置
# make //编译
# make install //安装
c.Libpng
# wget ?download //下载
# tar zxvf libpng-1.2.8-config.tar.gz //解压
# cd libpng-1.2.8-config //改变目录
注意:首先看有没有装libtool (whereis libtool),没有就需要yum install libtool.
# ./configure //配置
# make //编译
# make install //安装
64位的机器这样搞
cp /usr/share/libtool/config.sub .
cp /usr/share/libtool/config.guess .
./configure –enable-shared –enable-static
make
make install
d.jpeg
# wget //下载
# tar jpegsrc.v8b.tar.gz //解压
# cd jpeg-8b //改变目录
# ./configure –prefix=/usr/local/modules/jpeg6 –enable-shared –enable-static //配置
# make //编译
# make install //安装
e.GD
# wget //下载
# tar xzvf gd-2.0.33.tar.gz //解压
# cd gd-2.0.33 //改变目录
# ./configure –prefix=/usr/local/modules/gd –with-jpeg=/usr/local/modules/jpeg6 –with-png=/usr/local/libpng –with-zlib –with-freetype=/usr/local/modules/freetype //配置
# make //编译
# make install //安装
4.PHP
a.libxml2
# wget ftp://xmlsoft.org/libxml2/libxml2-2.7.2.tar.gz //下载
# tar zxvf libxml2-2.7.2.tar.gz //解压
# cd libxml2-2.7.2 //改变目录
# ./configure –prefix=/usr/local/libxml2 //配置
# make //编译
# make install //安装
b.curl (系统安装了就yum remove curl,然后下载一个新版的)
# wget //下载
# tar -zxvf curl-7.19.0.tar.gz //解压
# cd curl-7.19.0 //改变目录
# ./configure –prefix=/usr/local/curl //配置
# make //编译
# make install //安装
c.PHP
# wget
# tar jxvf php-5.2.8.tar.bz2
# cd php*
# ./configure –prefix=/usr/local/php –with-mysql=/usr/local/mysql –with-libxml-dir=/usr/local/libxml2 –with-gd=/usr/local/modules/gd –with-png-dir=/usr/local/libpng –with-jpeg-dir=/usr/local/modules/jpeg6 –with-zlib –with-freetype-dir=/usr/local/modules/freetype –enable-magic-quotes –with-apxs2=/usr/local/apache/bin/apxs –enable-ftp –with-config-file-path=/usr/local/php/etc –with-iconv –with-gettext –with-curl=/usr/local/curl
# make
# make install
# cp php.ini-dist /usr/local/php/etc/php.ini (这句。。。)
