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 ("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）：
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

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

/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 =

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 =

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 =

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?
- #!/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
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?

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：
引用
user www www;
worker_processes
8;
error_log /data1/logs/nginx_error.log crit;
pid /usr/local/webserver/nginx/nginx.pid;
