    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, 感谢Nginx为我们选择了 epoll and kqueue作为开发模型.
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. 你还能够 不间断服务的情况下进行软件版本的升级.

安装PHP 5.2.6（FastCGI模式）

安装php的时候，需要安装支持php的一些库，不过一般情况，装好linux系统时，这些库基本上都装好，所以支持php安装的软件，就在这儿不说了。如果make && make install时提示出错时，你可以看一下缺少什么，你就装什么。

tar zxvf php-5.2.6.tar.gz
cd php-5.2.6/
./configure –prefix=/usr/local/php –with-mysql=/usr/local/mysql –with-zlib-dir –with-freetype-dir=/usr –with-jpeg-dir=/usr –with-png-dir=/usr –enable-gd-native-ttf –with-gd –enable-ftp –with-iconv –with-gettext –with-curl –enable-fastcgi –with-openssl

make && make install
cd /usr/local/php/lib
cp php.ini-dist php.ini

cp /usr/local/php/bin/php  /usr/bin/php-cgi

1，修改php.ini

nano php.ini  按f6然后输入extension_dir

查找/usr/local/php/etc/php.ini中的extension_dir = “./”
修改为extension_dir = “/usr/local/php/lib/php/extensions/no-debug-non-zts-20060613/”

2，启动php-cgi

/usr/local/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -C 5 -f /usr/bin/php-cgi

nginx配置文件中的  fastcgi_pass 127.0.0.1:9000; 就是根据上面来的

3，查看一下

[zhangy@BlackGhost www]$ ps -e|grep php-cgi
3737 ?        00:00:00 php-cgi
3738 ?        00:00:03 php-cgi
3739 ?        00:00:03 php-cgi
3740 ?        00:00:04 php-cgi
3741 ?        00:00:03 php-cgi
3742 ?        00:00:03 php-cgi

安装nginx

tar zxvf nginx-0.8.35.tar.gz
cd nginx-0.8.35/
./configure –user=zhangy –group=users –prefix=/usr/local/nginx –with-http_stub_status_module –with-http_ssl_module –with-pcre=/usr/local/pcre
make && make install

1,配置nginx.conf

nano /usr/local/nginx/conf/nginx.conf

2，fastcgi.conf

cd /usr/local/nginx/conf

nano /usr/local/nginx/conf/fastcgi.conf

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;

3，优化linux内核参数

nano /etc/sysctl.conf

在末尾加上下面的东东

net.ipv4.tcp_max_syn_backlog = 65536
net.core.netdev_max_backlog =  32768
net.core.somaxconn = 32768

net.core.wmem_default = 8388608
net.core.rmem_default = 8388608
net.core.rmem_max = 16777216
net.core.wmem_max = 16777216

net.ipv4.tcp_timestamps = 0
net.ipv4.tcp_synack_retries = 2
net.ipv4.tcp_syn_retries = 2

net.ipv4.tcp_tw_recycle = 1
#net.ipv4.tcp_tw_len = 1
net.ipv4.tcp_tw_reuse = 1

net.ipv4.tcp_mem = 94500000 915000000 927000000
net.ipv4.tcp_max_orphans = 3276800

#net.ipv4.tcp_fin_timeout = 30
#net.ipv4.tcp_keepalive_time = 120
net.ipv4.ip_local_port_range = 1024  65535

4,启动nginx

ulimit -SHn 65535
/usr/local/webserver/nginx/sbin/nginx

5,查看启动

[zhangy@BlackGhost www]$ ps -e|grep nginx
4070 ?        00:00:00 nginx
4071 ?        00:00:00 nginx
4072 ?        00:00:00 nginx
4073 ?        00:00:00 nginx
4074 ?        00:00:00 nginx
4075 ?        00:00:00 nginx
4076 ?        00:00:00 nginx
4077 ?        00:00:00 nginx
4078 ?        00:00:00 nginx
4079 ?        00:00:00 nginx

开机启动

nano /etc/rc.local

ulimit -SHn 65535
/usr/local/bin/spawn-fcgi -a 127.0.0.1 -p 9000 -C 5 -f /usr/bin/php-cgi
/usr/local/nginx/sbin/nginx
