前言:本文是我撰写的关于搭建“Nginx
+ PHP(FastCGI)”Web服务器的第5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4篇文章相差不大,但增加了MySQL安装配置的信息、PHP 5.2.9 的 php-fpm
补丁(非官方)。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.nginx.org/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
0.7.54 + PHP 5.2.9 (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 0.7.54 + PHP 5.2.9 (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
0.7.54 + PHP 5.2.9 (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 5.3,另在RedHat
AS4上也安装成功)
一、获取相关开源程序:
1、【适用CentOS操作系统】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 openldap openldap-devel nss_ldap openldap-clients
openldap-servers
2、【适用RedHat操作系统】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

二、安装PHP 5.2.9(FastCGI模式)
1、编译安装PHP 5.2.9所需的支持库:
tar
zxvf libiconv-1.13.tar.gz
cd libiconv-1.13/
./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-0.9.9.9.tar.gz
cd mhash-0.9.9.9/
./configure
make

tar zxvf mcrypt-2.6.8.tar.gz
cd
mcrypt-2.6.8/
/sbin/ldconfig
./configure
make
make install
cd
../
2、编译安装MySQL 5.1.34
/usr/sbin/groupadd
mysql
/usr/sbin/useradd -g mysql mysql
tar zxvf mysql-5.1.34.tar.gz
cd
mysql-5.1.34/
./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-plugins=innobase
make && make
install
chmod +w /usr/local/webserver/mysql
chown -R mysql:mysql
/usr/local/webserver/mysql
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、创建MySQL数据库存放目录
mkdir
-p /data0/mysql/3306/data/
chown -R mysql:mysql
/data0/mysql/
②、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=/data0/mysql/3306/data --user=mysql
③、创建my.cnf配置文件:
vi /data0/mysql/3306/my.cnf
输入以下内容:
引用
[client]
default-character-set = utf8
port =
3306
socket =
/tmp/mysql.sock
[mysql]
prompt="(/u:blog.s135.com:)[/d]>

[mysqldump]
quick
max_allowed_packet =
32M
④、创建管理MySQL数据库的shell脚本:
vi /data0/mysql/3306/mysql
输入以下内容(这里的用户名admin和密码12345678接下来的步骤会创建):
view plaincopy to clipboardprint?
⑤、赋予shell脚本可执行权限:
chmod +x /data0/mysql/3306/mysql
⑥、启动MySQL:
/data0/mysql/3306/mysql start
⑦、通过命令行登录管理MySQL服务器(提示输入密码时直接回车):
/usr/local/webserver/mysql/bin/mysql -u root -p -S /tmp/mysql.sock
⑧、输入以下SQL语句,创建一个具有root权限的用户(admin)和密码(12345678):
GRANT
ALL PRIVILEGES ON *.* TO 'admin'@'localhost' IDENTIFIED BY '12345678';
GRANT
ALL PRIVILEGES ON *.* TO 'admin'@'127.0.0.1' IDENTIFIED BY
'12345678';
⑨、(可选)停止MySQL:
/data0/mysql/3306/mysql stop
3、编译安装PHP(FastCGI模式)
tar
zxvf php-5.2.9.tar.gz
gzip -cd php-5.2.9-fpm-0.5.10.diff.gz | patch -d
php-5.2.9 -p1
cd php-5.2.9/
./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 --with-ldap
--with-ldap-sasl
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-2.2.5.tgz
cd
memcache-2.2.5/
/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
../
tar zxvf ImageMagick.tar.gz
cd
ImageMagick-6.5.1-2/
./configure
make
make install
cd ../
tar
zxvf imagick-2.2.2.tgz
cd
imagick-2.2.2/
/usr/local/webserver/php/bin/phpize
./configure
--with-php-config=/usr/local/webserver/php/bin/php-config
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"
extension =
"imagick.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"/nextension = "imagick.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
view plaincopy to clipboardprint?
9、启动php-cgi进程,监听127.0.0.1的9000端口,进程数为200(如果服务器内存小于3GB,可以只开启64个进程),用户为www:
ulimit
-SHn 51200
/usr/local/webserver/php/sbin/php-fpm
start
注:/usr/local/webserver/php/sbin/php-fpm还有其他参数,包括:start|stop|quit|restart|reload|logrotate,修改php.ini后不重启php-cgi,重新加载配置文件使用reload。
三、安装Nginx 0.7.54
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-0.7.54.tar.gz
cd nginx-0.7.54/
./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;
worker_processes
8;
error_log /data1/logs/nginx_error.log crit;
pid /usr/local/webserver/nginx/nginx.pid;
#Specifies
