　　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 0.7.x + PHP 5.2.9（FastCGI）搭建胜过Apache十倍的Web服

　　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）：

　　Nginx 0.7.x + PHP 5.2.9（FastCGI）搭建胜过Apache十倍的Web服

　　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 AS4 & CentOS 4

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


　　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
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 /usr/lib/libmhash.so
ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2
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 5.1.34

/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]> "
no-auto-rehash

[mysqld]
#default-character-set = utf8
user = mysql
port = 3306
socket = /tmp/mysql.sock
basedir = /usr/local/webserver/mysql
datadir = /data0/mysql/3306/data
open_files_limit = 10240
back_log = 600
max_connections = 3000
max_connect_errors = 6000
table_cache = 614
external-locking = FALSE
max_allowed_packet = 32M
sort_buffer_size = 2M
join_buffer_size = 2M
thread_cache_size = 300
thread_concurrency = 8
query_cache_size = 32M
query_cache_limit = 2M
query_cache_min_res_unit = 2k
default-storage-engine = MyISAM
default_table_type = MyISAM
thread_stack = 192K
transaction_isolation = READ-COMMITTED
tmp_table_size = 246M
max_heap_table_size = 246M
long_query_time = 1
log_long_format
log-bin = /data0/mysql/3306/binlog
binlog_cache_size = 4M
binlog_format = MIXED
max_binlog_cache_size = 8M
max_binlog_size = 512M
expire_logs_days = 7
key_buffer_size = 256M
read_buffer_size = 1M
read_rnd_buffer_size = 16M
bulk_insert_buffer_size = 64M
myisam_sort_buffer_size = 128M
myisam_max_sort_file_size = 10G
myisam_max_extra_sort_file_size = 10G
myisam_repair_threads = 1
myisam_recover

skip-name-resolve
master-connect-retry = 10
slave-skip-errors = 1032,1062,126,1114,1146,1048,1396

server-id = 1

innodb_additional_mem_pool_size = 16M
innodb_buffer_pool_size = 2048M
innodb_data_file_path = ibdata1:1024M:autoextend
innodb_file_io_threads = 4
innodb_thread_concurrency = 8
innodb_flush_log_at_trx_commit = 2
innodb_log_buffer_size = 16M
innodb_log_file_size = 128M
innodb_log_files_in_group = 3
innodb_max_dirty_pages_pct = 90
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?

  1. #!/bin/sh
  3. mysql_port=3306
  4. mysql_username="admin"
  5. mysql_password="12345678"
  7. function_start_mysql()
  8. {
  9. printf "Starting MySQL.../n"
  10. /bin/sh /usr/local/webserver/mysql/bin/mysqld_safe --defaults-file=/data0/mysql/${mysql_port}/my.cnf 2>&1 > /dev/null &
  11. }
  13. function_stop_mysql()
  14. {
  15. printf "Stoping MySQL.../n"
  16. /usr/local/webserver/mysql/bin/mysqladmin -u ${mysql_username} -p${mysql_password} -S /tmp/mysql.sock shutdown
  17. }
  19. function_restart_mysql()
  20. {
  21. printf "Restarting MySQL.../n"
  22. function_stop_mysql
  23. sleep 5
  24. function_start_mysql
  25. }
  27. function_kill_mysql()
  28. {
  29. kill -9 $(ps -ef | grep 'bin/mysqld_safe' | grep ${mysql_port} | awk '{printf $2}')
  30. kill -9 $(ps -ef | grep 'libexec/mysqld' | grep ${mysql_port} | awk '{printf $2}')
  31. }
  33. if [ "$1" = "start" ]; then
  34. function_start_mysql
  35. elif [ "$1" = "stop" ]; then
  36. function_stop_mysql
  37. elif [ "$1" = "restart" ]; then
  38. function_restart_mysql
  39. elif [ "$1" = "kill" ]; then
  40. function_kill_mysql
  41. else
  42. printf "Usage: /data0/mysql/${mysql_port}/mysql {start|stop|restart|kill}/n"
  43. 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-5.2.9.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0改为1，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?

  1. xml version="1.0" ?>

　　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：
