安装步骤：
必须先安装apache或者mysql，之后才能安装php
1. 安装mysql
cd /usr/local/src/
wget http://mirrors.sohu.com/mysql/MySQL-5.1/mysql-5.1.72-linux-i686-glibc23.tar.gz
注意：上面的地址是32位机器用的，如果你的机器是64位，下载这个包
（wget http://mirrors.sohu.com/mysql/MySQL-5.1/mysql-5.1.72-linux-x86_64-glibc23.tar.gz）
tar zxvf/usr/local/src/mysql-5.1.72-linux-x86_64-glibc23.tar.gz
mv mysql-5.1.72-linux-x86_64-glibc23/usr/local/mysql
useradd -s /sbin/nologin mysql
cd /usr/local/mysql
mkdir -p /data/mysql
chown -R mysql:mysql /data/mysql
./scripts/mysql_install_db --user=mysql--datadir=/data/mysql
cp support-files/my-large.cnf /etc/my.cnf
cp support-files/mysql.server/etc/init.d/mysqld
chmod 755/etc/init.d/mysqld
vim /etc/init.d/mysqld #修改datadir
{basedir=/usr/local/mysql
{datadir=/data/mysql
chkconfig --add mysqld
chkconfig mysqld on
service mysqld start
2. 安装apache
wget http://http://mirrors.sohu.com/apache/httpd-2.2.31.tar.gz
tar jvxf httpd-2.2.31.tar.bz2
cd httpd-2.2.31
./configure \
--prefix=/usr/local/apache2 \
--with-included-apr \
--enable-so \
--enable-deflate=shared \
--enable-expires=shared \
--enable-rewrite=shared \
--with-pcre
make && make install
注：重启不了？
出现：httpd:couldnot reliably detemire the server's fally qualified domain name
解决：vim/usr/local/apache2/conf/httpd.conf
将#ServerNamelocalhost:80前的#去掉即可。
3. 安装php
wget http://mirrors.sohu.com/php/php-5.4.35.tar.gz
tar zxf php-5.4.35.tar.gz
cd php-5.4.35
./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
注：出现错误大多为依赖包没有安装，只许yum装上依赖包即可
若出现：configure:error: mcrypt.h not found. Please reinstall libmcrypt.
则需要：1、rpm -ivh "http://www.lishiming.net/data/p_w_upload/forum/epel-release-6-8_64.noarch.rpm"（centos6系列64位）
rpm -ivh "http://www.lishiming.net/data/p_w_upload/forum/epel-release-6-8_32.noarch.rpm "（32位）
2、yum install -y libmcrypt-devel
make&& make install
Apache与php之间的连接（php解析）
vim/usr/local/apache2/conf/httpd.conf
1、找到AddTypeapplication/x-gzip .gz .tgz
在其后面添加AddTypeapplication/x-httpd-php .php
2、找到<IfModule dir_module>DirectoryIndex index.html
</IfModule>
改为<IfModule dir_module>
DirectoryIndex index.html index.htm index.php
</IfModule>
