關于Linux環境Nginx安裝與調試以及PHP安裝參考此文即可：http://blog.csdn.net/unix21/article/details/8544922

linux版本：64位CentOS 6.4

Nginx版本：nginx1.8.0

php版本：php5.5.28 &?php5.4.44

所謂多版本多版本PHP就是php5.4和5.5以及其他版本在同一臺服務器。

假如php5.5是主版本已經安裝在/usr/local/php目錄下，那么再安裝其他版本的php再指定不同安裝目錄即可。

安裝第二個版本的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的偵聽端口為9001，因為主版本5.5.28是偵聽9000。

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

啟動php-fpm
#? /etc/init.d/php-fpm5.4.44

php安裝成功查看進程

#ps aux|grep php

這樣就已經起好php-fpm了。

配置Nginx

增加一段新的端口8054的配置并指向到9001以及指定目錄即可：

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配置如圖：

#user  nobody;

#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;#pid        logs/nginx.pid;events {worker_connections  1024;

重啟nginx

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

注意需要防火墻增加新端口的開啟，不然無法訪問：

防火墻配置

注意如果你希望在本地機器例如xp訪問虛擬機的網頁，如果是centos6需要修改防火墻啟動80端口

#?cd /etc/sysconfig

修改iptables文件，或者直接用vim編輯

#?vim /etc/sysconfig/iptables

添加下面一行，打開防火墻80端口:

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

重啟防火墻
# /etc/init.d/iptables restart

測試是否成功，查看phpinfo()
