关于参考此文即可：

linux版本：64位CentOS 6.4

Nginx版本：nginx1.8.0

php版本：php5.5.28 & php5.4.44

所谓多版本多版本PHP就是php5.4和5.5以及其他版本在同一台服务器。

假如php5.5是主版本已经安装在/usr/local/php目录下，那么再安装其他版本的php再指定不同安装目录即可。

安装第二个版本的PHP

# wget http://cn2.php.net/get/php-5.4.44.tar.gz/from/this/mirror

# tar zxvf php-5.4.44.tar.gz# cd php-5.4.44#./configure --prefix=/usr/local/php5.4.44 \

--with-curl \

--with-freetype-dir \

--with-gd \

--with-gettext \

--with-iconv-dir \

--with-kerberos \

--with-libdir=lib64 \

--with-libxml-dir \

--with-mysql \

--with-mysqli \

--with-openssl \

--with-pcre-regex \

--with-pdo-mysql \

--with-pdo-sqlite \

--with-pear \

--with-png-dir \

--with-xmlrpc \

--with-xsl \

--with-zlib \

--enable-fpm \

--enable-bcmath \

--enable-libxml \

--enable-inline-optimization \

--enable-gd-native-ttf \

--enable-mbregex \

--enable-mbstring \

--enable-pcntl \

--enable-shmop \

--enable-soap \

--enable-sockets \

--enable-sysvsem \

--enable-xml \

--enable-zip# make &&  make install# cp -R ./sapi/fpm/php-fpm.conf /usr/local/php5.4.44/etc/php-fpm.conf# cp php.ini-development /usr/local/php5.4.44/lib/php.ini# cp -R ./sapi/fpm/php-fpm /etc/init.d/php-fpm5.4.44

修改php-fpm.conf的侦听端口为9001，因为主版本5.5.28是侦听9000。

; Note: This value is mandatory.listen = 127.0.0.1:9001

启动php-fpm

#  /etc/init.d/php-fpm5.4.44

php安装成功查看进程

#ps aux|grep php

这样就已经起好php-fpm了。

配置Nginx

增加一段新的端口8054的配置并指向到9001以及指定目录即可：

server {

        listen       8054;        server_name  localhost;        location / {             #root   html;root /usr/www5.4.44;            index  index.html index.htm;        }        error_page   500 502 503 504  /50x.html;        location = /50x.html {             root   html;        }location ~ \.php$ { root html;fastcgi_pass 127.0.0.1:9001;fastcgi_index index.php;include fastcgi_params;fastcgi_param SCRIPT_FILENAME /usr/www5.4.44$fastcgi_script_name;}     }

nginx的配置文件nginx.conf在

# cd /usr/local/nginx/conf

完整的nginx配置如图：

重启nginx

# /usr/local/nginx/sbin/nginx -s reload

注意需要防火墙增加新端口的开启，不然无法访问：

防火墙配置

注意如果你希望在本地机器例如xp访问虚拟机的网页，如果是centos6需要修改防火墙启动80端口

# cd /etc/sysconfig

修改iptables文件，或者直接用vim编辑

# vim /etc/sysconfig/iptables

添加下面一行，打开防火墙80端口:

-A INPUT -m state --state NEW -m tcp -p tcp --dport 8054 -j ACCEPT

重启防火墙

# /etc/init.d/iptables restart

测试是否成功，查看phpinfo()
