  前言:本文是我撰写的关于搭建“Nginx + PHP(FastCGI)”Web服务器的第3篇文章,也是Nginx 0.6系列版本成为稳定版后的第一篇文章,安装、配置方式与以往略有不同,并增加了一些在生产环境运行中不断修改、调整,总结出的配置上的优化。

  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 的中文维基: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 0.6.31 + PHP 5.2.6 (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 0.6.31 + PHP 5.2.6 (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 0.6.31 + PHP 5.2.6 (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算高:

  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 libpng libpng-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel


  2、下载程序源码包:
  本文中提到的所有开源软件为截止到2008年6月5日的最新稳定版。
mkdir -p /data0/software
cd /data0/software
wget http://sysoev.ru/nginx/nginx-0.6.31.tar.gz
wget http://www.php.net/get/php-5.2.6.tar.gz/from/this/mirror
wget http://php-fpm.anight.org/downloads/head/php-5.2.6-fpm-0.5.8.diff.gz
wget http://dev.mysql.com/get/Downloads/MySQL-5.1/mysql-5.1.24-rc.tar.gz/from/http://mysql.ntu.edu.tw/
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.12.tar.gz
wget "http://downloads.sourceforge.net/mcrypt/libmcrypt-2.5.8.tar.gz?modtime=1171868460&big_mirror=0"
wget "http://downloads.sourceforge.net/mcrypt/mcrypt-2.6.7.tar.gz?modtime=1194463373&big_mirror=0"
wget http://pecl.php.net/get/memcache-2.2.3.tgz
wget "http://downloads.sourceforge.net/mhash/mhash-0.9.9.tar.gz?modtime=1175740843&big_mirror=0"
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-7.7.tar.gz
wget http://xcache.lighttpd.net/pub/Releases/1.2.2/xcache-1.2.2.tar.gz



  二、安装PHP 5.2.6(FastCGI模式)
  1、编译安装PHP 5.2.6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 ../

cp /usr/local/lib/libmcrypt.* /usr/lib
ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2

tar zxvf mcrypt-2.6.7.tar.gz
cd mcrypt-2.6.7/
./configure
make
make install
cd ../



  2、编译安装MySQL 5.1.24-rc
/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
tar zxvf mysql-5.1.24-rc.tar.gz
cd mysql-5.1.24-rc/
./configure --prefix=/usr/local/webserver/mysql/ --without-debug --with-unix-socket-path=/usr/local/webserver/mysql/mysql.sock --with-client-ldflags=-all-static --with-mysqld-ldflags=-all-static --enable-assembler --with-extra-charsets=gbk,gb2312,utf8 --with-pthread --enable-thread-safe-client
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 --defaults-file=/usr/local/webserver/mysql/my.cnf --basedir=/usr/local/webserver/mysql --datadir=/usr/local/webserver/mysql/data --user=mysql --pid-file=/usr/local/webserver/mysql/mysql.pid --skip-locking --port=3306 --socket=/tmp/mysql.sock


  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-5.2.6.tar.gz
gzip -cd php-5.2.6-fpm-0.5.8.diff.gz | patch -d php-5.2.6 -p1
cd php-5.2.6/
./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-debug --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
sed -i 's#-lz -lm -lxml2 -lz -lm -lxml2 -lz -lm -lcrypt#& -liconv#' Makefile
make
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-2.2.3.tgz
cd memcache-2.2.3/
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/webserver/php/bin/php-config
make
make install
cd ../

tar zxvf xcache-1.2.2.tar.gz
cd xcache-1.2.2/
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/webserver/php/bin/php-config --enable-xcache
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"

  再查找display_errors = On
  修改为display_errors = Off

  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/" extension = "memcache.so" #' /usr/local/webserver/php/etc/php.ini
sed -i 's#display_errors = On#display_errors = Off#' /usr/local/webserver/php/etc/php.ini


  6、配置XCache加速PHP:
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
[xcache-common]
zend_extension = /usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/xcache.so

[xcache.admin]
xcache.admin.user = "xcache"
; xcache.admin.pass = md5($yourpasswd)
xcache.admin.pass = "8e6867a5d05144cf4761d6481fc674a8"

[xcache]
xcache.cacher = On
xcache.shm_scheme = "mmap"
xcache.size = 32M
; cpu number (cat /proc/cpuinfo |grep -c processor)
xcache.count = 2
xcache.slots = 8k
xcache.ttl = 0
xcache.gc_interval = 0
xcache.var_size = 2M
; cpu number (cat /proc/cpuinfo |grep -c processor)
xcache.var_count = 2
xcache.var_slots = 8K
xcache.var_ttl = 0
xcache.var_maxttl = 0
xcache.var_gc_interval = 300
xcache.readonly_protection = Off
xcache.mmap_path = "/dev/zero"



  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 -g 48
/usr/sbin/useradd -u 48 -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:

  9、启动php-cgi进程,监听127.0.0.1的9000端口,进程数为128(如果服务器内存小于3GB,可以只开启25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 0.6.31
  1、安装Nginx所需的pcre库:
tar zxvf pcre-7.7.tar.gz
cd pcre-7.7/
./configure
make && make install
cd ../


  2、安装Nginx
tar zxvf nginx-0.6.31.tar.gz
cd nginx-0.6.31/
./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;

? ? ? ? ? ? ? ? ? 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`
