Multiple Versions of PHP run on server

有这个需求是测试服务器要上一套老的ecshop；

于是版本不能太高；

方案：

通过nginx把请求传递给不同版本的cgi处理；然而遇到了一些麻烦；编译安装的时候根本就走不通。（现在走通了，但是我觉得肯定还存在问题，就是说扩展是有作用范围的。通过yum install 的扩展支持，是不是全局的？全局的肯定影响性能）

step 1:下载源码包

sep  2:准备编译的参数

          参考： 

./configure \
--prefix=/usr/local/php.5.3 \
--with-pdo-pgsql \
--with-zlib-dir \
--with-freetype-dir \
--enable-mbstring \
--with-libxml-dir=/usr \
--enable-soap \
--enable-calendar \
--with-curl \
--with-mcrypt \
--with-zlib \
--with-gd \
--with-zlib \
--enable-sockets \
--enable-sysvsem \
--enable-sysvshm \
--enable-pcntl \
--enable-mbregex \
--with-mhash \
--enable-zip \
--with-pcre-regex \
--with-mysql=/usr/local/mysql\
--with-pdo-mysql \
--with-mysqli \
--with-png-dir=/usr \
--enable-gd-native-ttf \
--with-openssl \
--with-fpm-user=nginx \
--with-fpm-group=nginx \
--with-libdir=lib64 \
--enable-ftp \
--with-jpeg-dir=/usr/lib/
--enable-fpm

然后make && make install

step 3 复制ini文件到指定目录下；

Installing PHP SAPI module: cgi
Installing PHP CGI binary: /usr/local/php.5.3/bin/
Installing PHP CLI binary: /usr/local/php.5.3/bin/
Installing PHP CLI man page: /usr/local/php.5.3/man/man1/
Installing build environment: /usr/local/php.5.3/lib/php/build/
Installing header files: /usr/local/php.5.3/include/php/
Installing helper programs: /usr/local/php.5.3/bin/
program: phpize
program: php-config
Installing man pages: /usr/local/php.5.3/man/man1/

Installing PEAR environment: /usr/local/php.5.3/lib/php/
[PEAR] Archive_Tar - installed: 1.3.12

[PEAR] Structures_Graph- installed: 1.0.4
[PEAR] XML_Util - installed: 1.2.3
[PEAR] PEAR - installed: 1.9.5
Wrote PEAR system config file at: /usr/local/php.5.3/etc/pear.conf
You may want to add: /usr/local/php.5.3/lib/php to your php.ini include_path
/usr/local/php5.2.5/php-5.3.29/build/shtool install -c ext/phar/phar.phar /usr/local/php.5.3/bin
ln -s -f /usr/local/php.5.3/bin/phar.phar /usr/local/php.5.3/bin/phar
Installing PDO headers: /usr/local/php.5.3/include/php/ext/pdo/

step 4 启动一个cgi 进程

/usr/local/bin/spawn-fcgi -a 127.0.0.1 -p 9001 -C 5 -f /usr/local/php.5.3/bin/php-cgi（这里定了9001端口，当然你也可以通过修改config文件 指定端口）

step 5 前提你有spawn-fcgi 没有的话编译安装；

step 6 配置nginx 虚拟机  fastcgi_pass   127.0.0.1:9001;端口请注意
