nginx在ubuntu上的安装

1、安装Nginx

apt-get install nginx

（要最新版本下载下来编译吧）
装完应该能正常运行了。如果之前有装APACHE要改下端口。。。或者直接

apt-get remove apache2  
/etc/init.d/nginx stop  
/etc/init.d/nginx start

2、安装php-cgi

apt-get install php-cgi

（要自定义安装的编译吧）

3、改php-cgi的配置

Ubuntu下是/etc/php5/cgi/php.ini
之前有安装过php的话会复制apache的配置文件
打开cgi.fix_pathinfo选项：

cgi.fix_pathinfo=1;

4、改Nginx的fastcgi传递参数

Ubuntu下是/etc/nginx/fastcgi_params
默认应该已经设置好了，内容差不多就下面那样：

代码:

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_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 $server_protocol;  
fastcgi_param GATEWAY_INTERFACE CGI/1.1;  
fastcgi_param SERVER_SOFTWARE nginx/$nginx_version;  
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、创建VHost配置（这里只说Ubuntu下的，也就路径和包含文件目录的区别了）
在/etc/nginx/sites-available/下创建服务器配置文件比如myserver

ln -n /etc/nginx/sites-available/myserver /etc/nginx/sites-enabled/myserver

其实懒的话直接创建在enabled里也没问题－。－
内容填：

代码:

server {  
listen 80;  
server_name myserver.com;  
access_log /var/log/nginx/myserver.access.log;location / {  
root /wwwroot/myserver;  
index index.php;  
autoindex off;  
}  
location ~ \.php$ {  
include /etc/nginx/fastcgi_params;  
fastcgi_param SCRIPT_FILENAME /wwwroot/myserver/$fastcgi_script_name;  
fastcgi_pass 127.0.0.1:9000;  
fastcgi_index index.php;  
}  
# redirect server error pages to the static page /50x.html  
error_page 500 502 503 504 /50x.html;  
location = /50x.html {  
root /var/www/nginx-default;  
}  
# deny access to .htaccess files, if Apache’s document root  
location ~ /\.ht {  
deny all;  
}  
}

6、安装spawn-fcgi

下载可到这里，这东西已经独立出来了
http://redmine.lighttpd.net/projects/spawn-fcgi/wiki
下完后解压编译

sudo ./configure –prefix=/usr/local  
sudo make  
sudo make install

7、启动spaw-fcgi

sudo spawn-fcgi -a 127.0.0.1 -p 9000 -u www-data -g www-data -f /usr/bin/php5-cgi -F 10

哦，对后面10进程不爽的人可以取消或是加到100

8、重启Nginx

/etc/init.d/nginx restart

9、定义下hosts就可以看结果啦
编辑/etc/hosts加入

127.0.0.1 myserver.com

然后打开浏览器就可以看结果啦～
