安装步骤：
（系统要求：Linux 2.6+ 内核，本文中的Linux操作系统为CentOS 5.1，另在RedHat AS4上也安装成功）
一、获取相关开源程序：
1、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 libpng libpng-devel libxml2 libxml2-devel zlib zlib-devel glibc glibc-devel glib2 glib2-devel bzip2 bzip2-devel ncurses ncurses-devel curl curl-devel
2、下载程序源码包：
本文中提到的所有开源软件为截止到2008年6月5日的最新稳定版。（2008年6月底，sourceforge.net被GFW，下列的libmcrypt、mcrypt和mhash改从镜像站下载）
mkdir -p /data0/software
cd /data0/software
wget http://sysoev.ru/nginx/nginx-0.6.31.tar.gz
wget http://www.php.net/get/php-5.2.6.tar.gz/from/this/mirror
wget http://php-fpm.anight.org/downloads/head/php-5.2.6-fpm-0.5.8.diff.gz
wget http://dev.mysql.com/get/Downloads/MySQL-5.1/mysql-5.1.26-rc.tar.gz/from/http://mirror.x10.com/mirror/mysql/
wget http://ftp.gnu.org/pub/gnu/libiconv/libiconv-1.12.tar.gz
#wget "http://downloads.sourceforge.net/mcrypt/libmcrypt-2.5.8.tar.gz?modtime=1171868460&big_mirror=0"
wget http://mirror.optus.net/sourceforge/m/mc/mcrypt/libmcrypt-2.5.8.tar.gz
#wget "http://downloads.sourceforge.net/mcrypt/mcrypt-2.6.7.tar.gz?modtime=1194463373&big_mirror=0"
wget http://mirror.optus.net/sourceforge/m/mc/mcrypt/mcrypt-2.6.7.tar.gz
wget http://pecl.php.net/get/memcache-2.2.3.tgz
#wget "http://downloads.sourceforge.net/mhash/mhash-0.9.9.tar.gz?modtime=1175740843&big_mirror=0"
wget http://mirror.optus.net/sourceforge/m/mh/mhash/mhash-0.9.9.tar.gz
wget ftp://ftp.csx.cam.ac.uk/pub/software/programming/pcre/pcre-7.7.tar.gz
wget http://xcache.lighttpd.net/pub/Releases/1.2.2/xcache-1.2.2.tar.gz
二、安装PHP 5.2.6（FastCGI模式）
1、编译安装PHP 5.2.6所需的支持库：
tar zxvf libiconv-1.12.tar.gz
cd libiconv-1.12/
./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.tar.gz
cd mhash-0.9.9/
./configure
make
make install
cd ../
cp /usr/local/lib/libmcrypt.* /usr/lib
ln -s /usr/local/lib/libmhash.so.2 /usr/lib/libmhash.so.2
tar zxvf mcrypt-2.6.7.tar.gz
cd mcrypt-2.6.7/
./configure
make
make install
cd ../
2、编译安装MySQL 5.1.26-rc
/usr/sbin/groupadd mysql
/usr/sbin/useradd -g mysql mysql
tar zxvf mysql-5.1.26-rc.tar.gz
cd mysql-5.1.26-rc/
./configure --prefix=/usr/local/webserver/mysql/ --without-debug --with-unix-socket-path=/usr/local/webserver/mysql/mysql.sock --with-client-ldflags=-all-static --with-mysqld-ldflags=-all-static --enable-assembler --with-extra-charsets=gbk,gb2312,utf8 --with-pthread --enable-thread-safe-client
make && make install
chmod +w /usr/local/webserver/mysql
chown -R mysql:mysql /usr/local/webserver/mysql
cp support-files/my-medium.cnf /usr/local/webserver/mysql/my.cnf
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、以mysql用户帐号的身份建立数据表：
/usr/local/webserver/mysql/bin/mysql_install_db --defaults-file=/usr/local/webserver/mysql/my.cnf --basedir=/usr/local/webserver/mysql --datadir=/usr/local/webserver/mysql/data --user=mysql --pid-file=/usr/local/webserver/mysql/mysql.pid --skip-locking --port=3306 --socket=/tmp/mysql.sock
②、启动MySQL（最后的&表示在后台运行）
/bin/sh /usr/local/webserver/mysql/bin/mysqld_safe --defaults-file=/usr/local/webserver/mysql/my.cnf &
3、编译安装PHP（FastCGI模式）
tar zxvf php-5.2.6.tar.gz
gzip -cd php-5.2.6-fpm-0.5.8.diff.gz | patch -d php-5.2.6 -p1
cd php-5.2.6/
./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-debug --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
sed -i 's#-lz -lm -lxml2 -lz -lm -lxml2 -lz -lm -lcrypt#& -liconv#' Makefile
make
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-2.2.3.tgz
cd memcache-2.2.3/
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/webserver/php/bin/php-config
make
make install
cd ../
tar zxvf xcache-1.2.2.tar.gz
cd xcache-1.2.2/
/usr/local/webserver/php/bin/phpize
./configure --with-php-config=/usr/local/webserver/php/bin/php-config --enable-xcache
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"
再查找display_errors = On
修改为display_errors = Off
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"\n#' /usr/local/webserver/php/etc/php.ini
sed -i 's#display_errors = On#display_errors = Off#' /usr/local/webserver/php/etc/php.ini
6、配置XCache加速PHP：
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：
[xcache-common]7、创建www用户和组，以及供www.dbasky.net和www.dbasky.net/blog两个虚拟主机使用的目录：
zend_extension = /usr/local/webserver/php/lib/php/extensions/no-debug-non-zts-20060613/xcache.so
[xcache.admin]
xcache.admin.user = "xcache"
; xcache.admin.pass = md5($yourpasswd)
xcache.admin.pass = "8e6867a5d05144cf4761d6481fc674a8"
[xcache]
xcache.cacher = On
xcache.shm_scheme = "mmap"
xcache.size = 32M
; cpu number (cat /proc/cpuinfo |grep -c processor)
xcache.count = 2
xcache.slots = 8k
xcache.ttl = 0
xcache.gc_interval = 0
xcache.var_size = 2M
; cpu number (cat /proc/cpuinfo |grep -c processor)
xcache.var_count = 2
xcache.var_slots = 8K
xcache.var_ttl = 0
xcache.var_maxttl = 0
xcache.var_gc_interval = 300
xcache.readonly_protection = Off
xcache.mmap_path = "/dev/zero"
/usr/sbin/groupadd www -g 48
/usr/sbin/useradd -u 48 -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：9、启动php-cgi进程，监听127.0.0.1的9000端口，进程数为128（如果服务器内存小于3GB，可以只开启25个进程），用户为www：

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 0.6.31
1、安装Nginx所需的pcre库：
tar zxvf pcre-7.7.tar.gz
cd pcre-7.7/
./configure
make && make install
cd ../
2、安装Nginx
tar zxvf nginx-0.6.31.tar.gz
cd nginx-0.6.31/
./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
注意写个shell脚本使得ngin的日志可以和apache一样可以日志截断
在crontab中设置每天凌晨00:00分自动运行，将当天的日志压缩成一个gzip包存放，然后再将/data1/logs/access.log文件内容清空（注意：不能直接删除/data1/logs/access.log）。
#!/bin/sh4、创建Nginx配置文件
# This file run at 00:00
date=$(date -d "yesterday" +"%Y-%m-%d")
gzip -c /data1/logs/access.log > /data1/logs/${date}.log.gz
:>/data1/logs/access.log
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：
user www www;
worker_processes 8;
error_log /data1/logs/nginx_error.log crit;
pid /usr/local/webserver/nginx/nginx.pid;
#Specifies the value for maximum file descriptors that can be opened by this process.

fastcgi_busy_buffers_size 128k;
fastcgi_temp_file_write_size 128k;
fastcgi_temp_path /dev/shm;

gzip_min_length 1k;
gzip_buffers 4 8k;
gzip_http_version 1.1;
gzip_types text/plain application/x-javascript text/css text/html application/xml;
server
{
listen 80;
server_name www.dbasky.net;
index index.html index.htm index.php;
root /data0/htdocs/blog;
if (-d $request_filename)
{
rewrite ^/(.*)([^/])$ http://$host/$1$2/ permanent;
}
location ~ .*\.php?$
{
include fcgi.conf;
#fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
}
log_format access '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $http_x_forwarded_for';
access_log /data1/logs/access.log access;
}
server
{
listen 80;
server_name www.dbasky.net;
index index.html index.htm index.php;

if (-d $request_filename)
{
rewrite ^/(.*)([^/])$ http://$host/$1$2/ permanent;
}
location ~ .*\.php?$
{
include fcgi.conf;
#fastcgi_pass unix:/tmp/php-cgi.sock;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
}
log_format wwwlogs '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" $http_x_forwarded_for';
access_log /data1/logs/wwwlogs.log wwwlogs;
}
server
{
listen 80;
server_name status.www.dbasky.net;
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：
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：
ulimit -SHn 51200五、优化Linux内核参数
/usr/local/webserver/php/sbin/php-fpm start
/usr/local/webserver/nginx/sbin/nginx
vi /etc/sysctl.conf
在末尾增加以下内容：
net.ipv4.tcp_fin_timeout = 30使配置立即生效：
net.ipv4.tcp_keepalive_time = 300
net.ipv4.tcp_syncookies = 1
net.ipv4.tcp_tw_reuse = 1
net.ipv4.tcp_tw_recycle = 1
net.ipv4.ip_local_port_range = 5000 65000
/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：
