　　前言：本文是我撰写的关于搭建“Nginx + PHP（FastCGI）”Web服务器的第4篇文章。本系列文章作为国内最早详细介绍 Nginx + PHP 安装、配置、使用的资料之一，为推动 Nginx 在国内的发展产生了积极的作用。这是一篇关于Nginx 0.7.x系列版本的文章，安装、配置方式与第3篇文章相差不大，但配置参数有不同。Nginx 0.7.x系列版本虽然为开发版，但在很多大型网站的生产环境中已经使用。

　　Nginx ("engine x") 是一个高性能的 HTTP 和反向代理服务器，也是一个 IMAP/POP3/SMTP 代理服务器。 Nginx 是由 Igor Sysoev 为俄罗斯访问量第二的 Rambler.ru 站点开发的，它已经在该站点运行超过两年半了。Igor 将源代码以类BSD许可证的形式发布。

　　Nginx 超越 Apache 的高性能和稳定性，使得国内使用 Nginx 作为 Web 服务器的网站也越来越多，其中包括新浪博客、新浪播客、网易新闻等门户网站频道，六间房、56.com等视频分享网站，Discuz!官方论坛、水木社区等知名论坛，豆瓣、YUPOO相册、海内SNS、迅雷在线等新兴Web 2.0网站。

　　Nginx 的官方中文维基：http://wiki.codemongers.com/NginxChs

　　在高并发连接的情况下，Nginx是Apache服务器不错的替代品。Nginx同时也可以作为7层负载均衡服务器来使用。根据我的测试结果，Nginx 0.7.27 + PHP 5.2.8 (FastCGI) 可以承受3万以上的并发连接数，相当于同等环境下Apache的10倍。

　　根据我的经验，4GB内存的服务器+Apache（prefork模式）一般只能处理3000个并发连接，因为它们将占用3GB以上的内存，还得为系统预留1GB的内存。我曾经就有两台Apache服务器，因为在配置文件中设置的MaxClients为4000，当Apache并发连接数达到3800时，导致服务器内存和Swap空间用满而崩溃。

　　而这台 Nginx 0.7.27 + PHP 5.2.8 (FastCGI) 服务器在3万并发连接下，开启的10个Nginx进程消耗150M内存（15M*10=150M），开启的64个php-cgi进程消耗1280M内存（20M*64=1280M），加上系统自身消耗的内存，总共消耗不到2GB内存。如果服务器内存较小，完全可以只开启25个php-cgi进程，这样php-cgi消耗的总内存数才500M。

　　在3万并发连接下，访问Nginx 0.7.27 + PHP 5.2.8 (FastCGI) 服务器的PHP程序，仍然速度飞快。下图为Nginx的状态监控页面，显示的活动连接数为28457（关于Nginx的监控页配置，会在本文接下来所给出的Nginx配置文件中写明）：

　　我生产环境下的两台Nginx + PHP5（FastCGI）服务器，跑多个一般复杂的纯PHP动态程序，单台Nginx + PHP5（FastCGI）服务器跑PHP动态程序的处理能力已经超过“700次请求/秒”，相当于每天可以承受6000万（700*60*60*24=60480000）的访问量（更多信息见此），而服务器的系统负载也不高：

　　安装步骤：

　　（系统要求：Linux 2.6+ 内核，本文中的Linux操作系统为CentOS 5.1，另在RedHat AS4上也安装成功）

　　一、获取相关开源程序：

　　1、利用CentOS Linux系统自带的yum命令安装、升级所需的程序库（RedHat等其他Linux发行版可从安装光盘中找到这些程序库的RPM包，进行安装）：

sudo -s

LANG=C

yum -y install gcc gcc-c++ autoconf libjpeg libjpeg-devel libpng libpng-devel freetype freetype-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel e2fsprogs e2fsprogs-devel krb5 krb5-devel libidn libidn-devel openssl openssl-devel

　　2、RedHat等其他Linux发行版可从安装光盘中找到这些程序库的RPM包（事先可通过类似“rpm -qa | grep libjpeg”的命令查看所需的RPM包是否存在，通常是“xxx-devel”不存在，需要安装）。RedHat可以直接利用CentOS的RPM包安装，以下是RPM包下载网址：

　　①、RedHat AS4 & CentOS 4

　　http://mirror.be10.com/centos/4/os/i386/CentOS/RPMS/

　　http://mirror.be10.com/centos/4/os/x86_64/CentOS/RPMS/

wget http://blog.s135.com/soft/linux/nginx_php/pdo/PDO_MYSQL-1.0.2.tgz

　　二、安装PHP 5.2.8（FastCGI模式）

　　1、编译安装PHP 5.2.8所需的支持库：

tar zxvf libiconv-1.12.tar.gz

cd libiconv-1.12/

./configure --prefix=/usr/local

make

make install

cd ../

tar zxvf libmcrypt-2.5.8.tar.gz

cd libmcrypt-2.5.8/

./configure

make

make install

/sbin/ldconfig

cd libltdl/

./configure --enable-ltdl-install

make

make install

cd ../../

tar zxvf mhash-0.9.9.tar.gz

cd mhash-0.9.9/

./configure

make

make install

cd ../

ln -s /usr/local/lib/libmcrypt.la /usr/lib/libmcrypt.la

ln -s /usr/local/lib/libmcrypt.so /usr/lib/libmcrypt.so

ln -s /usr/local/lib/libmcrypt.so.4 /usr/lib/libmcrypt.so.4

ln -s /usr/local/lib/libmcrypt.so.4.4.8 /usr/lib/libmcrypt.so.4.4.8

ln -s /usr/local/lib/libmhash.a /usr/lib/libmhash.a

ln -s /usr/local/lib/libmhash.la /usr/lib/libmhash.la

ln -s /usr/local/lib/libmhash.so /usr/lib/libmhash.so

ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2

ln -s /usr/local/lib/libmhash.so.2.0.1 /usr/lib/libmhash.so.2.0.1

tar zxvf mcrypt-2.6.7.tar.gz

cd mcrypt-2.6.7/

/sbin/ldconfig

./configure

make

make install

cd ../

　　2、编译安装MySQL 5.1.30

/usr/sbin/groupadd mysql

/usr/sbin/useradd -g mysql mysql

tar zxvf mysql-5.1.30.tar.gz

cd mysql-5.1.30/

./configure --prefix=/usr/local/webserver/mysql/ --enable-assembler --with-extra-charsets=complex --enable-thread-safe-client --with-big-tables --with-readline --with-ssl --with-embedded-server --enable-local-infile --with-innodb

make && make install

chmod +w /usr/local/webserver/mysql

chown -R mysql:mysql /usr/local/webserver/mysql

cp support-files/my-medium.cnf /usr/local/webserver/mysql/my.cnf

cd ../

　　附：以下为附加步骤，如果你想在这台服务器上运行MySQL数据库，则执行以下两步。如果你只是希望让PHP支持MySQL扩展库，能够连接其他服务器上的MySQL数据库，那么，以下两步无需执行。

　　①、以mysql用户帐号的身份建立数据表：

/usr/local/webserver/mysql/bin/mysql_install_db --basedir=/usr/local/webserver/mysql --datadir=/usr/local/webserver/mysql/data --user=mysql

　　②、启动MySQL（最后的&表示在后台运行）

/bin/sh /usr/local/webserver/mysql/bin/mysqld_safe --defaults-file=/usr/local/webserver/mysql/my.cnf &

　　3、编译安装PHP（FastCGI模式）

tar zxvf php-5.2.8.tar.gz

gzip -cd php-5.2.8-fpm-0.5.10.diff.gz | patch -d php-5.2.8 -p1

cd php-5.2.8/

./configure --prefix=/usr/local/webserver/php --with-config-file-path=/usr/local/webserver/php/etc --with-mysql=/usr/local/webserver/mysql --with-mysqli=/usr/local/webserver/mysql/bin/mysql_config --with-iconv-dir=/usr/local --with-freetype-dir --with-jpeg-dir --with-png-dir --with-zlib --with-libxml-dir=/usr --enable-xml --disable-rpath --enable-discard-path --enable-safe-mode --enable-bcmath --enable-shmop --enable-sysvsem --enable-inline-optimization --with-curl --with-curlwrappers --enable-mbregex --enable-fastcgi --enable-fpm --enable-force-cgi-redirect --enable-mbstring --with-mcrypt --with-gd --enable-gd-native-ttf --with-openssl --with-mhash --enable-pcntl --enable-sockets

make ZEND_EXTRA_LIBS='-liconv'

make install

cp php.ini-dist /usr/local/webserver/php/etc/php.ini

cd ../

　　4、编译安装PHP5扩展模块

tar zxvf memcache-2.2.4.tgz

cd memcache-2.2.4/

/usr/local/webserver/php/bin/phpize

./configure --with-php-config=/usr/local/webserver/php/bin/php-config

make

make install

cd ../

tar jxvf eaccelerator-0.9.5.3.tar.bz2

cd eaccelerator-0.9.5.3/

/usr/local/webserver/php/bin/phpize

./configure --enable-eaccelerator=shared --with-php-config=/usr/local/webserver/php/bin/php-config

make

make install

cd ../

tar zxvf PDO_MYSQL-1.0.2.tgz

cd PDO_MYSQL-1.0.2/

/usr/local/webserver/php/bin/phpize

./configure --with-php-config=/usr/local/webserver/php/bin/php-config --with-pdo-mysql=/usr/local/webserver/mysql

make

make install

cd ../

　　5、修改php.ini文件

　　手工修改：查找/usr/local/webserver/php/etc/php.ini中的extension_dir = "./"

　　修改为extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"

　　并在此行后增加以下几行，然后保存：

　　extension = "memcache.so"

　　extension = "pdo_mysql.so"

　　再查找output_buffering = Off

　　修改为output_buffering = On

　　自动修改：若嫌手工修改麻烦，可执行以下shell命令，自动完成对php.ini文件的修改：

sed -i 's#extension_dir = "./"#extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"\nextension = "memcache.so"\nextension = "pdo_mysql.so"\n#' /usr/local/webserver/php/etc/php.ini

sed -i 's#output_buffering = Off#output_buffering = On#' /usr/local/webserver/php/etc/php.ini

　　6、配置eAccelerator加速PHP：

mkdir -p /usr/local/webserver/eaccelerator_cache

vi /usr/local/webserver/php/etc/php.ini

　　按shift+g键跳到配置文件的最末尾，加上以下配置信息：

引用

[eaccelerator]

zend_extension="/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/eaccelerator.so"

eaccelerator.shm_size="128"

eaccelerator.cache_dir="/usr/local/webserver/eaccelerator_cache"

eaccelerator.enable="1"

eaccelerator.optimizer="1"

eaccelerator.check_mtime="1"

eaccelerator.debug="0"

eaccelerator.filter=""

eaccelerator.shm_max="0"

eaccelerator.shm_ttl="300"

eaccelerator.shm_prune_period="120"

eaccelerator.shm_only="0"

eaccelerator.compress="1"

eaccelerator.compress_level="9"

　　修改配置文件：

vi /etc/sysctl.conf

　　输入以下内容：

引用

kernel.shmmax = 134217728

　　然后执行以下命令使配置生效：

/sbin/sysctl -p

　　7、创建www用户和组，以及供blog.s135.com和www.s135.com两个虚拟主机使用的目录：

/usr/sbin/groupadd www

/usr/sbin/useradd -g www www

mkdir -p /data0/htdocs/blog

chmod +w /data0/htdocs/blog

chown -R www:www /data0/htdocs/blog

mkdir -p /data0/htdocs/www

chmod +w /data0/htdocs/www

chown -R www:www /data0/htdocs/www

　　8、创建php-fpm配置文件（php-fpm是为PHP打的一个FastCGI管理补丁，可以平滑变更php.ini配置而无需重启php-cgi）：

　　在/usr/local/webserver/php/etc/目录中创建php-fpm.conf文件：

rm -f /usr/local/webserver/php/etc/php-fpm.conf

vi /usr/local/webserver/php/etc/php-fpm.conf

　　输入以下内容（如果您安装 Nginx + PHP 用于程序调试，请将以下的<value name="display_errors">0</value>改为<value name="display_errors">1</value>，以便显示PHP错误信息，否则，Nginx 会报状态为500的空白错误页）：

ulimit -SHn 51200

/usr/local/webserver/php/sbin/php-fpm start

　　三、安装Nginx 0.7.27

　　1、安装Nginx所需的pcre库：

tar zxvf pcre-7.8.tar.gz

cd pcre-7.8/

./configure

make && make install

cd ../

　　2、安装Nginx

tar zxvf nginx-0.7.27.tar.gz

cd nginx-0.7.27/

./configure --user=www --group=www --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module

make && make install

cd ../

　　3、创建Nginx日志目录

mkdir -p /data1/logs

chmod +w /data1/logs

chown -R www:www /data1/logs

　　4、创建Nginx配置文件

　　①、在/usr/local/webserver/nginx/conf/目录中创建nginx.conf文件：

rm -f /usr/local/webserver/nginx/conf/nginx.conf

vi /usr/local/webserver/nginx/conf/nginx.conf

　　输入以下内容：

引用

user www www;

}

server

{

listen 80;

server_name status.blog.s135.com;

location / {

stub_status on;

access_log off;

}

　　②、在/usr/local/webserver/nginx/conf/目录中创建fcgi.conf文件：

vi /usr/local/webserver/nginx/conf/fcgi.conf

　　输入以下内容：

引用

fastcgi_param GATEWAY_INTERFACE CGI/1.1;

fastcgi_param SERVER_SOFTWARE nginx;

fastcgi_param QUERY_STRING $query_string;

fastcgi_param REQUEST_METHOD $request_method;

fastcgi_param CONTENT_TYPE $content_type;

fastcgi_param CONTENT_LENGTH $content_length;

fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;

fastcgi_param SCRIPT_NAME $fastcgi_script_name;

fastcgi_param REQUEST_URI $request_uri;

fastcgi_param DOCUMENT_URI $document_uri;

fastcgi_param DOCUMENT_ROOT $document_root;

fastcgi_param SERVER_PROTOCOL $server_protocol;

fastcgi_param REMOTE_ADDR $remote_addr;

fastcgi_param REMOTE_PORT $remote_port;

fastcgi_param SERVER_ADDR $server_addr;

fastcgi_param SERVER_PORT $server_port;

fastcgi_param SERVER_NAME $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect

fastcgi_param REDIRECT_STATUS 200;

　　5、启动Nginx

ulimit -SHn 51200

/usr/local/webserver/nginx/sbin/nginx

　　四、配置开机自动启动Nginx + PHP

vi /etc/rc.local

　　在末尾增加以下内容：

引用

ulimit -SHn 51200

/usr/local/webserver/php/sbin/php-fpm start

/usr/local/webserver/nginx/sbin/nginx

　　五、优化Linux内核参数

vi /etc/sysctl.conf

　　在末尾增加以下内容：

引用

net.ipv4.tcp_fin_timeout = 30

net.ipv4.tcp_keepalive_time = 300

net.ipv4.tcp_syncookies = 1

net.ipv4.tcp_tw_reuse = 1

net.ipv4.tcp_tw_recycle = 1

net.ipv4.ip_local_port_range = 5000 65000

　　使配置立即生效：

/sbin/sysctl -p

　　六、在不停止Nginx服务的情况下平滑变更Nginx配置

　　1、修改/usr/local/webserver/nginx/conf/nginx.conf配置文件后，请执行以下命令检查配置文件是否正确：

/usr/local/webserver/nginx/sbin/nginx -t

　　如果屏幕显示以下两行信息，说明配置文件正确：

　　the configuration file /usr/local/webserver/nginx/conf/nginx.conf syntax is ok

　　the configuration file /usr/local/webserver/nginx/conf/nginx.conf was tested successfully

　　2、这时，输入以下命令查看Nginx主进程号：

ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ' ' '{print $2}'

　　屏幕显示的即为Nginx主进程号，例如：

　　6302

　　这时，执行以下命令即可使修改过的Nginx配置文件生效：

kill -HUP 6302

　　或者无需这么麻烦，找到Nginx的Pid文件：

kill -HUP `cat /usr/local/webserver/nginx/nginx.pid`

　　七、编写每天定时切割Nginx日志的脚本

　　1、创建脚本/usr/local/webserver/nginx/sbin/cut_nginx_log.sh

vi /usr/local/webserver/nginx/sbin/cut_nginx_log.sh

　　输入以下内容：

引用

#!/bin/bash

# This script run at 00:00

# The Nginx logs path

logs_path="/usr/local/webserver/nginx/logs/"

mkdir -p ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/

mv ${logs_path}access.log ${logs_path}$(date -d "yesterday" +"%Y")/$(date -d "yesterday" +"%m")/access_$(date -d "yesterday" +"%Y%m%d").log

kill -USR1 `cat /usr/local/webserver/nginx/nginx.pid`

　　2、设置crontab，每天凌晨00:00切割nginx访问日志

crontab -e

　　输入以下内容：

引用

00 00 * * * /bin/bash /usr/local/webserver/nginx/sbin/cut_nginx_log.sh
