在安装php之前确保mysql，nginx运行正常[root@localhost mysql]# netstat -lntup|egrep "nginx|mysql"

1.需要安装的软件

安装libiconv（./configure --prefix=/usr/local/libiconv）

安装libmcrypt（不是必须，建议安装）是一个加密的库

./configure

make

make install

sleep2

/sbin/ldconfig

cd libltdl/

./configure --enable-ltdl-install

make

make install

cd ../../cd

安装mhash

./configure

make

make install

sleep 2

cd ../

rm -fr /usr/lib64/libmcrypt.*

rm -fr /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/bin/libmcrypt-config /usr/bin/libmcrypt-config

安装mcrypt

/sbin/ldconfig

./configure LD_LIBRARY_PATH=/usr/local/lib

make

make install

cd ../

sleep 2

2.安装php

[root@localhost tools]# yum install libxslt* -y

./configure  \
