一直听说nginx对于fcgi支持是多么的好，俄罗斯轻量级web服务器nginx支持的并发连接时apache的10倍
多。但是占用物理内存不到150M，今天终于可以研究下了！
lighttpd如果加在其中也使作为配置php-cgi程序！
下面摘自官网评价
==============================================================
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 是一个很牛的高性能 Web 和反向代理服务器, 它具有有很多非常优越的特性:
在高连接并发的情况下，Nginx 是 Apache 服务器不错的替代品：Nginx 在美国是做虚拟主机生意
的老板们经常选择的软件平台之一。能够支持高达 50,000 个并发连接数的响应。
Nginx 作为负载均衡服务器：Nginx 既可以在内部直接支持 Rails 和 PHP 程序对外进行服务, 也
可以支持作为 HTTP 代理服务器对外进行服务。Nginx 采用 C 进行编写，不论是系统资源开销还是 CPU
使用效率都比 Perlbal 要好很多。
作为邮件代理服务器：Nginx 同时也是一个非常优秀的邮件代理服务器（最早开发这个产品的目的
之一也是作为邮件代理服务器），Last.fm 描述了成功并且美妙的使用经验。
Nginx 是一个 安装非常的简单，配置文件 非常简洁（还能够支持 perl 语法），Bugs 非常少的
服务器：Nginx 启动特别容易，并且几乎可以做到 7*24 不间断运行，即使运行数个月也不需要重新启动
。还能够不间断服务的情况下进行软件版本的升级。
==============================================================================
我们开始下载所需要的软件
Nginx的中文wiki:
wget
wget
wget
wget
wget
Mysql自己下载，地址我这便记录丢掉了！目前来说Php-fpm只有5.2.6的补丁！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
php-fpm官网：
另外服务器上安装以下软件包
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
默认都会安装~~
==========================================================
第一步：安装Mysql，不论是源代码还是二进制只要能运行就好了
cp mysql-5.0.22.tar.gz /usr/local/src
cd /usr/local/src
tar zxvf mysql-5.0.22.tar.gz
cd mysql-5.0.22
./configure --prefix=/usr/local/mysql --sysconfdir=/etc --localstatedir=/var/lib/mysql --
with-charset=gbk --with-xcharset=all
make && make install
usr/local/mysql/bin/mysql_install_db
groupadd -g 20000 mysql
useradd -u 20000 root -g mysql mysql
chown -R mysql /var/lib/mysql
cp /usr/local/mysql/share/mysql/my-medium.cnf /etc/my.cnf
/usr/local/mysql/bin/mysql/mysqld_safe --user=root &
/usr/local/mysql/bin/mysqladmin -u root -p password 6xuan
enter password:回车
/usr/local/mysql/bin/mysql -u root -p
输入密码：6xuan
进入mysql
成功了~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
第二步：安装php和php-fpm
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/php --with-mysql=/usr/local/mysql/ --with-gd=/usr --with-gd-lib=/usr/lib --with-jpeg dir=/usr --with-png-dir=/usr/include/ --with-zlib --enable-mbstring --enable-iconv --with-curl --with-curlwrappers --enable-mbregex --enable-fastcgi --enable-fpm --enable-force-cgi-redirect --with-openssl
make && make install
cp php.ini-dist /usr/local/lib/php/php.ini
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
第三步，配置xcache和memcache，让php加速
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
[root@localhost xcache-1.2.2]# /usr/local/php/bin/phpize
./configure --with-php-config=/usr/local/php/bin/php-config --enable-xcache
make
make install
cd ../
执行
sed -i 's#extension_dir = "./"#extension_dir = "/usr/local/php/lib/php/extensions/no-debug-
non-zts-20060613/"\nextension = "memcache.so"\n#' /usr/local/lib/php/php.ini
sed -i 's#display_errors = On#display_errors = Off#' /usr/local/lib/php/php.ini
它将会自动修改php.ini
然后继续配置php.ini，让他增加xcache加速
vi /usr/local/lib/php/php.ini
在最后面加入
[xcache-common]
zend_extension = /usr/local/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"
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
第四步：配置php-fpm.conf
创建php-fpm启动的用户和组
[root@localhost php]# /usr/sbin/groupadd www -g 480
[root@localhost php]# /usr/sbin/useradd -u 480 -g www www
vi /usr/local/php/etc/php-fpm.conf
用下面的代替里面内容
===============================================================================
All relative paths in this config are relative to php's install prefix
Pid file
/usr/local/php/logs/php-fpm.pid
Error log file
/usr/local/php/logs/php-fpm.log

For endless request processing please specify 0
Equivalent to PHP_FCGI_MAX_REQUESTS
10240
Comma separated list of ipv4 addresses of FastCGI clients that allowed to connect.
Equivalent to FCGI_WEB_SERVER_ADDRS environment in original php.fcgi (5.2.2+)

2
==============================================================================
启动php-fpm进程
/usr/local/php/sbin/php-fpm start
你可以用 ps -aux| grep php-cgi
查看是否存在进程
netstat -ant看是否在9000端口侦听

第5步，安装pcre
tar zxvf pcre-7.7.tar.gz
cd pcre-7.7/
./configure
make && make install
~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
第六步，安装配置nginx
./configure --user=www --group=www --prefix=/usr/local/nginx --with-http_stub_status_module
--with-http_ssl_module
make && make install
修改/usr/local/nginx/conf/nginx.conf
用下面内容替换
==========================================
user www www;
worker_processes 8;
error_log /var/log/nginx/nginx_error.log crit;
pid /var/run/nginx.pid;

}
===========================================================
里面的
error_log /var/log/nginx/nginx_error.log crit;
pid /var/run/nginx.pid;
请根绝自己的修改
运行以下命令检测配置文件是否无误：
＃ /usr/local/nginx/sbin/nginx -t -c /usr/local/nginx/conf/nginx.conf
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
创建fcgi的配置文件
vi /usr/local/nginx/conf/fcgi.conf
里面输入
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;
然后启动nginx
启动Nginx
/usr/local/nginx/sbin/nginx
