我们在安装配置服务器LNPM环境时应该考虑到PHP多版本并存的问题，下面是实现Linux系统下为Nginx安装多版本PHP的实现方法

linux版本：64位CentOS 6.4

Nginx版本：nginx1.8.0

php版本：php5.5.28 & php5.4.44

注意假如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配置如下：

#user nobody;

worker_processes 4;

#error_log logs/error.log;

#error_log logs/error.log notice;

#error_log logs/error.log info;

#pid logs/nginx.pid;

events {

worker_connections 1024;

}

http {

include mime.types;

default_type application/octet-stream;

#log_format main '$remote_addr - $remote_user [$time_local] "$request" '

# '$status $body_bytes_sent "$http_referer" '

# '"$http_user_agent" "$http_x_forwarded_for"';

#access_log logs/access.log main;

sendfile on;

#tcp_nopush on;

#keepalive_timeout 0;

keepalive_timeout 65;

#gzip on;

server {

listen 80;

server_name localhost;

#charset koi8-r;

#access_log logs/host.access.log main;

location / {

#root html;

root /usr/www;

index index.html index.htm;

}

#error_page 404 /404.html;

# redirect server error pages to the static page /50x.html

#

error_page 500 502 503 504 /50x.html;

location = /50x.html {

root html;

}

# proxy the PHP scripts to Apache listening on 127.0.0.1:80

#

#location ~ .php$ {

# proxy_pass http://127.0.0.1;

#}

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000

#

#location ~ .php$ {

# root html;

# fastcgi_pass 127.0.0.1:9000;

# fastcgi_index index.php;

# fastcgi_param SCRIPT_FILENAME /scripts$fastcgi_script_name;

# include fastcgi_params;

#}

location ~ .php$ {

root html;

fastcgi_pass 127.0.0.1:9000;

fastcgi_index index.php;

include fastcgi_params;

fastcgi_param SCRIPT_FILENAME /usr/www$fastcgi_script_name;

}

# deny access to .htaccess files, if Apache's document root

# concurs with nginx's one

#

#location ~ /.ht {

# deny all;

#}

}

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;

}

}

# another virtual host using mix of IP-, name-, and port-based configuration

#

#server {

# listen 8000;

# listen somename:8080;

# server_name somename alias another.alias;

# location / {

# root html;

# index index.html index.htm;

# }

#}

# HTTPS server

#

#server {

# listen 443 ssl;

# server_name localhost;

# ssl_certificate cert.pem;

# ssl_certificate_key cert.key;

# ssl_session_cache shared:SSL:1m;

# ssl_session_timeout 5m;

# ssl_ciphers HIGH:!aNULL:!MD5;

# ssl_prefer_server_ciphers on;

# location / {

# root html;

# index index.html index.htm;

# }

#}

}

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()

以上即是Linux系统下为Nginx安装多版本PHP的方法，希望对大家有用
