安装环境：CENTOS6.5，nginx1.6.2，php-5.5.18，mysql5.5.38
在安装软件之前安装epel源，就可以直接用yum安装libmcrypt,mhash,mcrypt等php扩展。
安装nginx
解决依赖关系，安装开发包组"Development Tools"和 "Server Platform Development"。
#tar –xf nginx-1.6.2
./configure \
--prefix=/usr/local/nginx \
--conf-path=/etc/nginx/nginx.conf \
--error-log-path=/var/log/nginx/error.log \
--http-log-path=/var/log/nginx/access.log \
--pid-path=/var/run/nginx/nginx.pid \
--lock-path=/var/lock/nginx.lock \
--user=nginx \
--group=nginx \
--http-client-body-temp-path=/var/tmp/nginx/client/ \
--http-proxy-temp-path=/var/tmp/nginx/proxy/ \
--http-fastcgi-temp-path=/var/tmp/nginx/fcgi/ \
--http-uwsgi-temp-path=/var/tmp/nginx/uwsgi \
--http-scgi-temp-path=/var/tmp/nginx/scgi \
--with-pcre
#make && make install
添加nginx启动脚本，设置开机启动，请见上一篇博客
安装php-5.5.18
安装mcrypt libmcrypt mhash 等php扩展
# yum –y install mcrypt libmcrypt-devel mhash-devel
安装php图型扩展支持
# yum install -y libxml2-devel libjpeg-devel libpng-devel freetype-devel openssl-devel libcurl-devel libmcrypt-devel gd-devel
#tar –xf php-5.5.18.tar.bz2
#cd php-5.5.18
#./configure --prefix=/usr/local/php55 --with-config-file-path=/usr/local/php55/etc --with-mysql=mysqlnd --with-zlib --enable-xml --disable-rpath --enable-bcmath --enable-shmop --enable-sysvsem --with-curl --enable-fpm --enable-opcache --with-mcrypt --with-gd --with-openssl --with-mhash --enable-sockets --with-xmlrpc -enable-zip --enable-soap --with-config-file-scan-dir=/etc/php.d --with-bz2 --with-curl --with-jpeg-dir --with-png-dir
# make && make install
# cp php.ini-production /usr/local/php55/etc/php.ini #为php提供配置文件
#ln –s /usr/local/php55/etc/php.ini /etc/php.ini #为php.ini在/etc目录下创建软链接
# cp sapi/fpm/init.d.php-fpm /etc/rc.d/init.d/php-fpm
# chmod +x /etc/rc.d/init.d/php-fpm
# chkconfig --add php-fpm
# chkconfig php-fpm on #配置php-fpm,为php-fpm提供Sysv init脚本，并将其添加至服务列表
# cp /usr/local/php55/etc/php-fpm.conf.default /usr/local/php55/etc/php-fpm.conf #为php-fpm提供配置文件
编辑php-fpm的配置文件：
# vim /usr/local/php55/etc/php-fpm.conf
配置fpm的相关选项为你所需要的值，并启用pid文件（如下最后一行）：
pm.max_children = 50 #设定php子进程最大数为50
pm.start_servers = 5 #启动php时子进程数为52上
pm.min_spare_servers = 2 #空闲php子进程最少为2个
pm.max_spare_servers = 8 #空闲php子进程最大为8个
pid = /usr/local/php/var/run/php-fpm.pid #pid文件路径
上面这些参数是可以根据系统性能和负载情况去调整的，在生产环境中这些参数可能会比这些数字要大很多，也可以设定php的子进程个数为静态的值。如果要设置静态的值，需要更改 pm = static ,php-fpm默认为动态的 pm = dynamic
# service php-fpm start 启动php-fpm
nginx配置文件设置及整合nginx和php5.5
nginx
的配置文件核心模块为main和events,此外还包括标准http模块，可选http模块和邮件模块，还可支持诸多第三方模块。main用于配置错误
日志、进程、及权限等相关的参数，events用于配置I/O模型，如epoll,kqueue,select或poll等。nginx的主配置文件由几
个段组成，main，http, server,upstrean和location，被称为nginx的上下文，支持嵌套。

}
}
} |
如上所示,php和nginx组合到一块了。
MySQL配置
MySQL我启用前面博客中搭建的drbd高可用mysql服务器，过程请见http://piao719.blog.51cto.com/287547/1562390
IP地址为：10.204.80.89
搭建ecshop
上传到/usr/local/nginx/html/ecshop 目录
Strict Standards: Non-static method cls_image::gd_version() should
not be called statically in ＼install＼includes＼lib_installer.php on line
31
解决：找到install/includes/lib_installer.php中的第31行 return
cls_image::gd_version();然后在找到include/cls_image.php中的678行，发现gd_version()方
法未声明静态static，所以会出错。这时候只要：
将function gd_version()改成static function gd_version()即可。
检测环境的时候提示：是否支持 JPEG是不支持的。
解决：查看发现有libjpeg.lib库，GD2库也有，都加载了，也都正常。查看ecshop源代码发现install/includes/lib_installer.php中第100行,JPEG写成了JPG，正确的应该是：
$jpeg_enabled = ($gd_info['JPEG Support'] === true) ? $_LANG['support'] : $_LANG['not_support'];
给cert、data、images、includes、temp、themes目录加777权限
# cd /usr/local/nginx/html/ecshop
# chmod -R 777 themes/ temp/ includes/ data/ cert/ images/
检查环境完成
配置系统
首先在10.204.80.89这台mysql服务器上创建ecshop数据库，然后添加一个帐号来管理这个数据库
mysql>create database ecshop;
mysql>grant all on ecshop.* to 'ecsuser'@'10.204.%.%' identified by "ecspass";
mysql>flush privileges;
然后照提示把所有信息填完整
安装数据库失败，提示date.timezone时区设置有问题，
修改/etc/php.ini里面的date.timezone = “Asia/Shanghai”时区，或都在php代码里面添加<?php date_default_timezone_set("PRC"); ?>这一句即可。安装完成
压力测试，这里只是用http自带的ab工具简单测试一下启用opcache缓存与不启用缓存的效果。
首先不启用php自带的opcache缓存器的测试结果如下

启用opcache,在/etc/php.ini文件中的[opcache]中添加
zend_extension=/usr/local/php55/lib/php/extensions/no-debug-non-zts-20121212/opcache.so
并把下面的这些参数打开
opcache.enable=1
opcache.enable_cli=1
opcache.memory_consumption=256
opcache.interned_strings_buffer=16
opcache.max_accelerated_files=5000
opcache.revalidate_freq=60
opcache.load_comments=1
上面这些参数在生产环境中可以根据实际的需要做出修改
重启php-fpm，再测试一下

可以看出来启用opcache缓存的效果比不启用的结果想比，响应时间少了70%，所以php开启opcode是非常有必要的 。
