php官方下载地址: http://www.php.net/downloads.php

下载php:

[rot@localhost httpd-2.2.16]# cd /usr/local/src[root@localhost src]# wget http://am1.php.net/distributions/php-5.3.27.tar.gz

解压:

[root@localhost src]# tar zxvf php-5.3.27.tar.gz （bz2格式用：tar jvxf .....）

配置编译参数:

[root@localhost src]# cd php-5.3.27[root@localhost php-5.3.27]# ./configure \--prefix=/usr/local/php \--with-apxs2=/usr/local/apache2/bin/apxs \--with-config-file-path=/usr/local/php/etc  \--with-mysql=/usr/local/mysql \--with-libxml-dir \--with-gd \--with-jpeg-dir \--with-png-dir \--with-freetype-dir \--with-iconv-dir \--with-zlib-dir \--with-bz2 \--with-openssl \--with-mcrypt \--enable-soap \--enable-gd-native-ttf \--enable-mbstring \--enable-sockets \--enable-exif \--disable-ipv6

在这一步，遇到如下错误:

configure: error: xml2-config not found. Please check your libxml2 installation.

解决办法是:

yum install -y libxml2-devel

还有错误:

configure: error: Cannot find OpenSSL's <evp.h>

解决办法是:

yum install -y openssl openssl-devel

错误:

checking for BZip2 in default path... not foundconfigure: error: Please reinstall the BZip2 distribution

解决办法:

yum install -y bzip2 bzip2-devel

错误:

configure: error: png.h not found.

解决办法:

yum install -y libpng libpng-devel

错误:

configure: error: freetype.h not found.

解决办法:

yum install -y freetype freetype-devel

错误:

configure: error: mcrypt.h not found. Please reinstall libmcrypt.

解决办法:

rpm -ivh "http://www.aminglinux.com/bbs/data/attachment/forum/month_1211/epel-release-6-7.noarch.rpm"  或   yum install -y epel-releaseyum install -y  libmcrypt-devel

因为centos6.x 默认的yum源没有libmcrypt-devel 这个包，只能借助第三方yum源或者epel的yum源。

在这一步，也许还会遇到诸多错误，遇到上面未列出的错误时，请参照    http://blog.sina.com.cn/s/blog_167f23bf50102xdki.html

编译:

[root@localhost php-5.3.27]# make

安装:

[root@localhost php-5.3.27]# make install

拷贝配置文件:

[root@localhost php-5.3.27]# cp php.ini-production /usr/local/php/etc/php.ini

Apache主配置文件为：/usr/local/apache2/conf/httpd.conf

#vim /usr/local/apache2/conf/httpd.conf

找到:

AddType application/x-gzip .gz .tgz

在该行下面添加:

AddType application/x-httpd-php .php

找到:

<IfModule dir_module>

   DirectoryIndex index.html + index.php

</IfModule>

在DirectoryIndex index.htm后面加上index.php

找到：

<IfModule dir_module>    DirectoryIndex index.html</IfModule>

将该行改为:

<IfModule dir_module>    DirectoryIndex index.html index.htm index.php</IfModule>

找到:

#ServerName www.example.com:80

修改为:

ServerName localhost:80
