Nginx 0.7.x + PHP 5.2.10（FastCGI）搭建勝過(guò)Apache十倍的Web服務(wù)器
[文章作者：張宴 本文版本：v5.4 最后修改：2009.06.26 轉(zhuǎn)載請(qǐng)注明原文鏈接：http://blog.s135.com/nginx_php_v5/]
前言：本文是我撰寫的關(guān)于搭建“Nginx + PHP（FastCGI）”Web服務(wù)器的第5篇文章。本系列文章作為國(guó)內(nèi)最早詳細(xì)介紹 Nginx + PHP 安裝、配置、使用的資料之一，為推動(dòng) Nginx 在國(guó)內(nèi)的發(fā)展產(chǎn)生了積極的作用。這是一篇關(guān)于Nginx 0.7.x系列版本的文章，安裝、配置方式與第4篇文章相差不大，但增加了MySQL安裝配置的信息、PHP 5.2.10 的 php-fpm 補(bǔ)丁。Nginx 0.7.x系列版本雖然為開發(fā)版，但在很多大型網(wǎng)站的生產(chǎn)環(huán)境中已經(jīng)使用。

Nginx ("engine x") 是一個(gè)高性能的 HTTP 和反向代理服務(wù)器，也是一個(gè) IMAP/POP3/SMTP 代理服務(wù)器。 Nginx 是由 Igor Sysoev 為俄羅斯訪問(wèn)量第二的 Rambler.ru 站點(diǎn)開發(fā)的，它已經(jīng)在該站點(diǎn)運(yùn)行超過(guò)兩年半了。Igor 將源代碼以類BSD許可證的形式發(fā)布。
Nginx 超越 Apache 的高性能和穩(wěn)定性，使得國(guó)內(nèi)使用 Nginx 作為 Web 服務(wù)器的網(wǎng)站也越來(lái)越多，其中包括新浪博客、新浪播客、網(wǎng)易新聞等門戶網(wǎng)站頻道，六間房、56.com等視頻分享網(wǎng)站，Discuz!官方論壇、水木社區(qū)等知名論壇，豆瓣、YUPOO相冊(cè)、海內(nèi)SNS、迅雷在線等新興Web 2.0網(wǎng)站。
Nginx 的官方中文維基：http://wiki.nginx.org/NginxChs
在高并發(fā)連接的情況下，Nginx是Apache服務(wù)器不錯(cuò)的替代品。Nginx同時(shí)也可以作為7層負(fù)載均衡服務(wù)器來(lái)使用。根據(jù)我的測(cè)試結(jié)果，Nginx 0.7.61 + PHP 5.2.10 (FastCGI) 可以承受3萬(wàn)以上的并發(fā)連接數(shù)，相當(dāng)于同等環(huán)境下Apache的10倍。
根據(jù)我的經(jīng)驗(yàn)，4GB內(nèi)存的服務(wù)器+Apache（prefork模式）一般只能處理3000個(gè)并發(fā)連接，因?yàn)樗鼈儗⒄加?GB以上的內(nèi)存，還得為系統(tǒng)預(yù)留1GB的內(nèi)存。我曾經(jīng)就有兩臺(tái)Apache服務(wù)器，因?yàn)樵谂渲梦募性O(shè)置的MaxClients為4000，當(dāng)Apache并發(fā)連接數(shù)達(dá)到3800時(shí)，導(dǎo)致服務(wù)器內(nèi)存和Swap空間用滿而崩潰。
而這臺(tái) Nginx 0.7.61 + PHP 5.2.10 (FastCGI) 服務(wù)器在3萬(wàn)并發(fā)連接下，開啟的10個(gè)Nginx進(jìn)程消耗150M內(nèi)存（15M*10=150M），開啟的64個(gè)php-cgi進(jìn)程消耗1280M內(nèi)存（20M*64=1280M），加上系統(tǒng)自身消耗的內(nèi)存，總共消耗不到2GB內(nèi)存。如果服務(wù)器內(nèi)存較小，完全可以只開啟25個(gè)php-cgi進(jìn)程，這樣php-cgi消耗的總內(nèi)存數(shù)才500M。
在3萬(wàn)并發(fā)連接下，訪問(wèn)Nginx 0.7.61 + PHP 5.2.10 (FastCGI) 服務(wù)器的PHP程序，仍然速度飛快。下圖為Nginx的狀態(tài)監(jiān)控頁(yè)面，顯示的活動(dòng)連接數(shù)為28457（關(guān)于Nginx的監(jiān)控頁(yè)配置，會(huì)在本文接下來(lái)所給出的Nginx配置文件中寫明）：
我生產(chǎn)環(huán)境下的兩臺(tái)Nginx + PHP5（FastCGI）服務(wù)器，跑多個(gè)一般復(fù)雜的純PHP動(dòng)態(tài)程序，單臺(tái)Nginx + PHP5（FastCGI）服務(wù)器跑PHP動(dòng)態(tài)程序的處理能力已經(jīng)超過(guò)“700次請(qǐng)求/秒”，相當(dāng)于每天可以承受6000萬(wàn)（700*60*60*24=60480000）的訪問(wèn)量（更多信息見此），而服務(wù)器的系統(tǒng)負(fù)載也不高：
下面是用100個(gè)并發(fā)連接分別去壓生產(chǎn)環(huán)境中同一負(fù)載均衡器VIP下、提供相同服務(wù)的兩臺(tái)服務(wù)器，一臺(tái)為Nginx，另一臺(tái)為Apache，Nginx每秒處理的請(qǐng)求數(shù)是Apache的兩倍多，Nginx服務(wù)器的系統(tǒng)負(fù)載、CPU使用率遠(yuǎn)低于Apache：
你可以將連接數(shù)開到10000～30000，去壓Nginx和Apache上的phpinfo.php，這是用瀏覽器訪問(wèn)Nginx上的phpinfo.php一切正常，而訪問(wèn)Apache服務(wù)器的phpinfo.php，則是該頁(yè)無(wú)法顯示。4G內(nèi)存的服務(wù)器，即使再優(yōu)化，Apache也很難在“webbench -c 30000 -t 60 http://xxx.xxx.xxx.xxx/phpinfo.php”的壓力情況下正常訪問(wèn)，而調(diào)整參數(shù)優(yōu)化后的Nginx可以。

注意：webbench 做壓力測(cè)試時(shí)，該軟件自身也會(huì)消耗CPU和內(nèi)存資源，為了測(cè)試準(zhǔn)確，請(qǐng)將 webbench 安裝在別的服務(wù)器上。

為什么Nginx的性能要比Apache高得多？這得益于Nginx使用了最新的epoll（Linux 2.6內(nèi)核）和kqueue（freebsd）網(wǎng)絡(luò)I/O模型，而Apache則使用的是傳統(tǒng)的select模型。目前Linux下能夠承受高并發(fā)訪問(wèn)的Squid、Memcached都采用的是epoll網(wǎng)絡(luò)I/O模型。
處理大量的連接的讀寫，Apache所采用的select網(wǎng)絡(luò)I/O模型非常低效。下面用一個(gè)比喻來(lái)解析Apache采用的select模型和Nginx采用的epoll模型進(jìn)行之間的區(qū)別：
假設(shè)你在大學(xué)讀書，住的宿舍樓有很多間房間，你的朋友要來(lái)找你。select版宿管大媽就會(huì)帶著你的朋友挨個(gè)房間去找，直到找到你為止。而epoll版宿管大媽會(huì)先記下每位同學(xué)的房間號(hào)，你的朋友來(lái)時(shí)，只需告訴你的朋友你住在哪個(gè)房間即可，不用親自帶著你的朋友滿大樓找人。如果來(lái)了10000個(gè)人，都要找自己住這棟樓的同學(xué)時(shí)，select版和epoll版宿管大媽，誰(shuí)的效率更高，不言自明。同理，在高并發(fā)服務(wù)器中，輪詢I/O是最耗時(shí)間的操作之一，select和epoll的性能誰(shuí)的性能更高，同樣十分明了。
安裝步驟：
?。ㄏ到y(tǒng)要求：Linux 2.6+ 內(nèi)核，本文中的Linux操作系統(tǒng)為CentOS 5.3，另在RedHat AS4上也安裝成功）
一、獲取相關(guān)開源程序：
1、【適用CentOS操作系統(tǒng)】利用CentOS Linux系統(tǒng)自帶的yum命令安裝、升級(jí)所需的程序庫(kù)（RedHat等其他Linux發(fā)行版可從安裝光盤中找到這些程序庫(kù)的RPM包，進(jìn)行安裝）：

?、?、賦予shell腳本可執(zhí)行權(quán)限：
chmod +x /data0/mysql/3306/mysql
?、蕖?dòng)MySQL：
/data0/mysql/3306/mysql start
?、?、通過(guò)命令行登錄管理MySQL服務(wù)器（提示輸入密碼時(shí)直接回車）：
/usr/local/webserver/mysql/bin/mysql -u root -p -S /tmp/mysql.sock
⑧、輸入以下SQL語(yǔ)句，創(chuàng)建一個(gè)具有root權(quán)限的用戶（admin）和密碼（12345678）：
GRANT ALL PRIVILEGES ON *.* TO 'admin'@'localhost' IDENTIFIED BY '12345678';
GRANT ALL PRIVILEGES ON *.* TO 'admin'@'127.0.0.1' IDENTIFIED BY '12345678';
?、?、（可選）停止MySQL：
/data0/mysql/3306/mysql stop
3、編譯安裝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、編譯安裝PHP5擴(kuò)展模塊
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 = "./"
修改為extension_dir = "/usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/"
并在此行后增加以下幾行，然后保存：
extension = "memcache.so"
extension = "pdo_mysql.so"
extension = "imagick.so"
再查找output_buffering = Off
修改為output_buffering = On
自動(dòng)修改：若嫌手工修改麻煩，可執(zhí)行以下shell命令，自動(dòng)完成對(duì)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鍵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_prune_period="3600"
eaccelerator.shm_only="0"
eaccelerator.compress="1"
eaccelerator.compress_level="9"
--------------------------------------------------------------------------------
7、創(chuàng)建www用戶和組，以及供blog.s135.com和www.s135.com兩個(gè)虛擬主機(jī)使用的目錄：
/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、創(chuàng)建php-fpm配置文件（php-fpm是為PHP打的一個(gè)FastCGI管理補(bǔ)丁，可以平滑變更php.ini配置而無(wú)需重啟php-cgi）：
在/usr/local/webserver/php/etc/目錄中創(chuàng)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
輸入以下內(nèi)容（如果您安裝 Nginx + PHP 用于程序調(diào)試，請(qǐng)將以下的<value name="display_errors">0</value>改為<value name="display_errors">1</value>，以便顯示PHP錯(cuò)誤信息，否則，Nginx 會(huì)報(bào)狀態(tài)為500的空白錯(cuò)誤頁(yè)）：view plaincopy to clipboardprint?

六、在不停止Nginx服務(wù)的情況下平滑變更Nginx配置
1、修改/usr/local/webserver/nginx/conf/nginx.conf配置文件后，請(qǐng)執(zhí)行以下命令檢查配置文件是否正確：
/usr/local/webserver/nginx/sbin/nginx -t
如果屏幕顯示以下兩行信息，說(shuō)明配置文件正確：
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、這時(shí)，輸入以下命令查看Nginx主進(jìn)程號(hào)：
ps -ef | grep "nginx: master process" | grep -v "grep" | awk -F ' ' '{print $2}'
屏幕顯示的即為Nginx主進(jìn)程號(hào)，例如：
6302
這時(shí)，執(zhí)行以下命令即可使修改過(guò)的Nginx配置文件生效：
kill -HUP 6302
或者無(wú)需這么麻煩，找到Nginx的Pid文件：
kill -HUP `cat /usr/local/webserver/nginx/nginx.pid`
--------------------------------------------------------------------------------
七、編寫每天定時(shí)切割Nginx日志的腳本
1、創(chuàng)建腳本/usr/local/webserver/nginx/sbin/cut_nginx_log.sh
vi /usr/local/webserver/nginx/sbin/cut_nginx_log.sh
輸入以下內(nèi)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、設(shè)置crontab，每天凌晨00:00切割nginx訪問(wèn)日志
crontab -e
輸入以下內(nèi)容：
引用
00 00 * * * /bin/bash /usr/local/webserver/nginx/sbin/cut_nginx_log.sh
--------------------------------------------------------------------------------
