【服务器】nginx二级域名配置

关于Nginx二级域名的配置，网上有好多文章和教程（好多都一样的），然而发现有太多复制粘贴且不适用的，这里安利一个炒鸡简单的方式配置nginx二级域名的方法。

首先介绍使用到的服务器的环境LNMP环境(其中nginx版本1.4.6，服务器是ubuntu 14.04的)，可能因为版本问题有配置的方式和文件的位置有细微不同。

服务商域名配置

我们先去域名提供商哪里去将我们的域名和我们的主机（公网IP）匹配上

开始配置顶级域名

这个配完直接访问域名验证是否可以正常访问到我们的主机（这里配置完成通常在1分钟左右生效），完成之后开始配置二级域名

同样的道理，这里配置完，验证一下能否正常访问

Nginx服务器配置

域名提供商上配置的信息相当在DNS服务器上给我们配置了，这个配置后只能将我们的主机和域名匹配上，我们还需要在服务器上配置来将我们的项目配置到二级域名上，比如说我们服务器上有个博客项目叫blog,我们的域名是qq.com,我想通过blog.qq.com访问到我们的blog项目，那么我们需要把我们这个想法告诉服务器，通过服务器的配置文件

nginx的目录在/etc/nginx   在/etc/nginx目录下nginx.conf是主要配置文件，里面有这样的描述

http{

include /etc/nginx/conf.d/*.conf;
include /etc/nginx/sites-enabled/*;

}

包含了指定目录下的配置文件，所以我们去看一下这两个文件夹，其中/etc/nginx/conf.d目录里是空的， /etc/nginx/sites-enabled目录里有个叫default的文件

打开这个文件（下面是整个文件的描述，自定义的server配置我会标红，如果不想细看，可以直接往下拉）

# You may add here your
# server {
# ...
# }
# statements for each of your virtual hosts to this file
# '#'在linux中通常表示注释当行，这里面我们发现Google的Nginx还是挺贴心的，给出了解释和参考文档地址，如果我们的服务器有https访问得需求，也可以在这个文件中配置

#
# Generally, you will want to move this file somewhere, and start with a clean
# file but keep this around for reference. Or just disable in sites-enabled.

# Please see /usr/share/doc/nginx-doc/examples/ for more detailed examples.

server {

#location = /50x.html {

# pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
#
location ~ \.php$ {
# fastcgi_split_path_info ^(.+\.php)(/.+)$;
# # NOTE: You should have "cgi.fix_pathinfo = 0;" in php.ini
#
# With php5-cgi alone:
include /etc/nginx/fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
# With php5-fpm:
# fastcgi_pass unix:/var/run/php5-fpm.sock;
fastcgi_index index.php;
fastcgi_param SCRIPT_FILENAME /usr/share/nginx/html$fastcgi_script_name;
#include fastcgi_params;
}



# deny access to .htaccess files, if Apache's document root
# concurs with nginx's one
#
#location ~ /\.ht {
# deny all;
#}
}


#MY CONFIG START
server

listen   80;
server_name  qq.com;
  root   /usr/share/nginx/html;
    index  index.php index.html index.htm;
    location ~ \.php$ {
include /etc/nginx/fastcgi_params;
fastcgi_pass 127.0.0.1:9000;
fastcgi_index index.php;
}
}

#先配置的是qq.com,相信我有配置这个的必要性，location里面的是为了让我们的Nginx服务器知道.php文件要去找php解释器执行，不配置可能会出现访问即下载文件的现象
#不要问我为什么，我是抄上面那个默认的server的，错不了，手动滑稽
