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。

  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

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 plaincopy to clipboardprint?



  • #!/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/
./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 --with-xmlrpc --enable-zip --enable-soap --without-pear
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

cd ../

tar jxvf eaccelerator-0.9.5.3.tar.bz2
cd eaccelerator-0.9.5.3/

  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/

    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

#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
