1、下載源碼包
wget 網址/php-5.4.45.tar
2、解壓源碼包
tar -zxvf php-5.4.45.tar
3、創建一個安裝目錄
mkdir /usr/local/php
4、進入解壓後的目錄中，初始化安裝環境：
./configure \
--prefix=/usr/local/php \
--with-apxs2=/usr/local/apache/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
錯誤
configure: error: jpeglib.h not found.
