下边的安装配置方法，我试了一晚上没有成功，可能因为我的系统环境比较复杂，所以建议：
先安装PHP。使用yum命令安装，在安装配置MySQL，具体做法看博客中其他文章，至于Nginx服务器可以安装完这两个之后再安装配置，因为我目前不使用Nginx，直接使用Apache服务器，所以就没有在系统上编译安装Nginx，目前使用Wordpress，不需要Nginx，只要PHP和Mysql安装配置好，就可以了；
1.下载PHP依赖库：
wget http://soft.beauty-soft.net/lib/libiconv/libiconv-1.13.1.tar.gz
wget http://soft.beauty-soft.net/lib/mcrypt/libmcrypt-2.5.8.tar.gz
wget http://soft.beauty-soft.net/lib/mcrypt/mcrypt-2.6.8.tar.gz
wget http://soft.beauty-soft.net/lib/mhash/mhash-0.9.9.9.tar.gz
wget http://soft.beauty-soft.net/lib/libiconv/php-5.3.6.tar.gz
2.下载后安装：
tar zxvf libiconv-1.13.1.tar.gz
cd libiconv-1.13.1/
./configure --prefix=/usr/local
make
make install
cd ../
tar zxvf libmcrypt-2.5.8.tar.gz
cd libmcrypt-2.5.8/
./configure
make
make install
/sbin/ldconfig
cd libltdl/
./configure --enable-ltdl-install
make
make install
cd ../../
tar zxvf mhash-0.9.9.9.tar.gz
cd mhash-0.9.9.9/
./configure
make
make install
cd ../
ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la
ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so
ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4
ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8
ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a
ln -s /usr/local/lib/libmhash.la /usr/lib/libmhash.la
ln -s /usr/local/lib/libmhash.so /usr/lib/libmhash.so
ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2
ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1
ln -s /usr/local/bin/libmcrypt-config /usr/bin/libmcrypt-config
tar zxvf mcrypt-2.6.8.tar.gz
cd mcrypt-2.6.8/
/sbin/ldconfig
./configure
make
make install
cd ../
3.安装PHP：必须加入php-fpm扩展，还有MySQL数据库的相应扩展；
tar zxvf php-5.3.6.tar.gz
cd php-5.3.6
./configure --prefix=/usr/local/php --with-config-file-path=/usr/local/php/etc --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-discard-path --enable-magic-quotes --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-fastcgi --enable-fpm --enable-force-cgi-redirect --enable-mstring --with-mcrypt --enable-ftp --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets --with-xmlrpc --enable-zip --enable-soap --without-pear --with-gettext --with-mime-magic --with-mysql=mysqlnd --with-mysqli=mysqlnd --with-pdo-mysql=mysqlnd
4.执行错误：configure: error: xml2-config not found. Please check your libxml2 installation.
解决办法：
5.执行错误：configure: error: libjpeg.(a|so) not found.
解决办法：
6.执行错误：configure: error: libpng.(a|so) not found.
解决办法：ln -s /usr/lib64/libpng.so /usr/lib/libpng.so
make ZEND_EXTRA_LIBS='-liconv'
7.执行错误：make: *** [ext/dom/node.lo] Error 1
解决办法：在这之前要安装patch命令到linux中：yum -y install patch
8.执行错误：make: *** [sapi/cgi/php-cgi] Error 1
解决办法：
make install
