Linux：安装php

一、环境准备（lamp环境:linux+apache+php+mysql)

1、安装php之前，首先要检查一下相关lib库

rpm -qa zlib libxml libjpeg freetype libpng gd curl libiconv zlib-devel libxml2-devel libjpeg-devel freetype-devel libpng-devel gd-devel curl-devel

如果没有安装的，要安装上 yum install zlib libxml libjpeg freetype libpng gd curl libiconv zlib-devel libxml2-devel libjpeg-devel freetype-devel libpng-devel gd-devel curl-devel

yum install openssl-devel -y

yum install libxslt-devel -y

2、安装libiconv,下载安装包libiconv-1.14.tar.gz，

安装

tar zxvf libiconv-1.14.tar.gz

cd libiconv-1.14

./configure --prefix=/usr/local/libiconv

make

make install

安装libmcrypt(非必须）

tar zxvf libmcrypt-2.5.8.tar.gz
cd libmcrypt-2.5.8
./configure
make
make install
sleep 2
/sbin/ldconfig
cd libltdl/
./configure --enable-ltdl-install
make
make install
cd ../../

安装mhash

tar zvxf mhash-0.9.9.9.tar.gz
cd mhash-0.9.9.9
./configure
make
make install
sleep 2
cd ../

rm -f /usr/lib64/libmcrypt.*
rm -f /usr/lib64/libmhash*
ln -s /usr/local/lib64/libmcrypt.la /usr/lib64/libmcrypt.la
ln -s /usr/local/lib64/libmcrypt.so /usr/lib64/libmcrypt.so
ln -s /usr/local/lib64/libmcrypt.so.4 /usr/lib64/libmcrypt.so.4
ln -s /usr/local/lib64/libmcrypt.so.4.4.8 /usr/lib64/libmcrypt.so.4.4.8
ln -s /usr/local/lib64/libmhash.a /usr/lib64/libmhash.a
ln -s /usr/local/lib64/libmhash.la /usr/lib64/libmhash.la
ln -s /usr/local/lib64/libmhash.so /usr/lib64/libmhash.so
ln -s /usr/local/lib64/libmhash.so.2 /usr/lib64/libmhash.so.2
ln -s /usr/local/lib64/libmhash.so.2.0.1 /usr/lib64/libmhash.so.2.0.1
ln -s /usr/local/lib64/libmcrypt-config /usr/lib64/libmcrypt-config

安装mcrypt:

tar zxvf mcrypt-2.6.8.tar.gz
cd mcrypt-2.6.8/
/sbin/ldconfig
./configure LD_LIBRARY_PATH=/usr/local/lib
make
make install
cd ../
sleep 2

3、安装好apache和mysql

二、安装php

1、下载安装包php-5.3.27.tar.gz

2、解压并进入目录

tar zxvf php-5.3.27.tar.gz

cd php-5.3.27

3、安装

编译

./configure \
--prefix=/application/php5.3.27 \　　　　　　　　　　　　php安装路径
--with-apxs2=/application/apache/bin/apxs \　　　　　　　　apache下的apxs路径，通过apxs增加php扩展模块到apache中
--with-mysql=/application/mysql \　　　　　　　　　　　　mysql安装路径
--with-xmlrpc \
--with-openssl \
--with-zlib \
--with-freetype-dir \
--with-gd \
--with-jpeg-dir \
--with-png-dir \
--with-iconv=/usr/local/libiconv \
--enable-short-tags \
--enable-sockets \
--enable-zend-multibyte \
--enable-soap \
--enable-mbstring \
--enable-static \
--enable-gd-native-ttf \
--with-curl \
--with-xsl \
--enable-ftp \
--with-libxml-dir
