Nginx 0.7.x + PHP 5.2.10（FastCGI）搭建胜过Apache十倍的Web服务器

[文章作者：张宴本文版本：v5.4 最后修改：2009.06.26 转载请注明原文链接：http://blog.s135.com/nginx_php_v5/]

　　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 5.2.10 的 php-fpm 补丁。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 0.7.61 + PHP 5.2.10 (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 0.7.61 + PHP 5.2.10 (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 0.7.61 + PHP 5.2.10 (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：

　　

　　下面是用100个并发连接分别去压生产环境中同一负载均衡器VIP下、提供相同服务的两台服务器，一台为Nginx，另一台为Apache，Nginx每秒处理的请求数是Apache的两倍多，Nginx服务器的系统负载、CPU使用率远低于Apache：

　　你可以将连接数开到10000～30000，去压Nginx和Apache上的phpinfo.php，这是用浏览器访问Nginx上的phpinfo.php一切正常，而访问Apache服务器的phpinfo.php，则是该页无法显示。4G内存的服务器，即使再优化，Apache也很难在“webbench -c 30000 -t 60 http://xxx.xxx.xxx.xxx/phpinfo.php”的压力情况下正常访问，而调整参数优化后的Nginx可以。

　　webbench 下载地址：http://blog.s135.com/post/288/

　　注意：webbench 做压力测试时，该软件自身也会消耗CPU和内存资源，为了测试准确，请将 webbench 安装在别的服务器上。

　　为什么Nginx的性能要比Apache高得多？这得益于Nginx使用了最新的epoll（Linux 2.6内核）和kqueue（freebsd）网络I/O模型，而Apache则使用的是传统的select模型。目前Linux下能够承受高并发访问的Squid、Memcached都采用的是epoll网络I/O模型。

　　处理大量的连接的读写，Apache所采用的select网络I/O模型非常低效。下面用一个比喻来解析Apache采用的select模型和Nginx采用的epoll模型进行之间的区别：

　　假设你在大学读书，住的宿舍楼有很多间房间，你的朋友要来找你。select版宿管大妈就会带着你的朋友挨个房间去找，直到找到你为止。而epoll版宿管大妈会先记下每位同学的房间号，你的朋友来时，只需告诉你的朋友你住在哪个房间即可，不用亲自带着你的朋友满大楼找人。如果来了10000个人，都要找自己住这栋楼的同学时，select版和epoll版宿管大妈，谁的效率更高，不言自明。同理，在高并发服务器中，轮询I/O是最耗时间的操作之一，select和epoll的性能谁的性能更高，同样十分明了。

　　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：

wget http://blog.s135.com/soft/linux/nginx_php/imagick/imagick-2.2.2.tgz

　　二、安装PHP 5.2.10（FastCGI模式）
　　1、编译安装PHP 5.2.10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
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.2.0.1 /usr/lib/libmhash.so.2.0.1

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 5.1.35

/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
tar zxvf mysql-5.1.35.tar.gz
cd mysql-5.1.35/
./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

default-character-set = utf8
port = 3306
socket  = /tmp/mysql.sock

innodb_lock_wait_timeout = 120
innodb_file_per_table = 0
[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 plain copy to clipboard print ?

#!/bin/sh
mysql_port=3306
mysql_username="admin"
mysql_password="12345678"
function_start_mysql()
{
printf "Starting MySQL...\n"
/bin/sh /usr/local/webserver/mysql/bin/mysqld_safe --defaults-file=/data0/mysql/${mysql_port}/my.cnf 2>&1 > /dev/null &
}
function_stop_mysql()
{
printf "Stoping MySQL...\n"
/usr/local/webserver/mysql/bin/mysqladmin -u ${mysql_username} -p${mysql_password} -S /tmp/mysql.sock shutdown
}
function_restart_mysql()
{
printf "Restarting MySQL...\n"
function_stop_mysql
sleep 5
function_start_mysql
}
function_kill_mysql()
{
kill -9 $(ps -ef | grep 'bin/mysqld_safe' | grep ${mysql_port} | awk '{printf $2}')
kill -9 $(ps -ef | grep 'libexec/mysqld' | grep ${mysql_port} | awk '{printf $2}')
}
if [ "$1" = "start" ]; then
function_start_mysql
elif [ "$1" = "stop" ]; then
function_stop_mysql
elif [ "$1" = "restart" ]; then
function_restart_mysql
elif [ "$1" = "kill" ]; then
function_kill_mysql
else
printf "Usage: /data0/mysql/${mysql_port}/mysql {start|stop|restart|kill}\n"
fi

#!/bin/shmysql_port=3306mysql_username="admin"mysql_password="12345678"function_start_mysql(){ printf "Starting MySQL...\n" /bin/sh /usr/local/webserver/mysql/bin/mysqld_safe --defaults-file=/data0/mysql/${mysql_port}/my.cnf 2>&1 > /dev/null &}function_stop_mysql(){ printf "Stoping MySQL...\n" /usr/local/webserver/mysql/bin/mysqladmin -u ${mysql_username} -p${mysql_password} -S /tmp/mysql.sock shutdown}function_restart_mysql(){ printf "Restarting MySQL...\n" function_stop_mysql sleep 5 function_start_mysql}function_kill_mysql(){ kill -9 $(ps -ef | grep 'bin/mysqld_safe' | grep ${mysql_port} | awk '{printf $2}') kill -9 $(ps -ef | grep 'libexec/mysqld' | grep ${mysql_port} | awk '{printf $2}')}if [ "$1" = "start" ]; then function_start_mysqlelif [ "$1" = "stop" ]; then function_stop_mysqlelif [ "$1" = "restart" ]; thenfunction_restart_mysqlelif [ "$1" = "kill" ]; thenfunction_kill_mysqlelse printf "Usage: /data0/mysql/${mysql_port}/mysql {start|stop|restart|kill}\n"fi
　　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-5.2.10.tar.gz
gzip -cd php-5.2.10-fpm-0.5.11.diff.gz | patch -d php-5.2.10 -p1
cd php-5.2.10/

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

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
sed -i "s#; always_populate_raw_post_data = On#always_populate_raw_post_data = On#g" /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="64"
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="3600"
eaccelerator.shm_prune_period="3600"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"

--------------------------------------------------------------------------------

　　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）：view plaincopy to clipboardprint?

</configuration>　　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 0.7.61
　　1、安装Nginx所需的pcre库：

tar zxvf pcre-7.9.tar.gz
cd pcre-7.9/
./configure
make && make install
cd ../

　　2、安装Nginx

tar zxvf nginx-0.7.61.tar.gz
cd nginx-0.7.61/
./configure --user=www --group=www --prefix=/usr/local/webserver/nginx --with-http_stub_status_module --with-http_ssl_module

  }

  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
# Add
net.ipv4.tcp_max_syn_backlog = 65536
net.core.netdev_max_backlog =  32768
net.core.somaxconn = 32768

net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216

net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_synack_retries = 2
net.ipv4.tcp_syn_retries = 2

net.ipv4.tcp_tw_recycle = 1
#net.ipv4.tcp_tw_len = 1
net.ipv4.tcp_tw_reuse = 1

net.ipv4.tcp_mem = 94500000 915000000 927000000
net.ipv4.tcp_max_orphans = 3276800

#net.ipv4.tcp_fin_timeout = 30
#net.ipv4.tcp_keepalive_time = 120
net.ipv4.ip_local_port_range = 1024  65535

　　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

--------------------------------------------------------------------------------
