LNMP--Nginx 默认虚拟主机

  在之前的笔记中说过，apache 中有一个默认的虚拟主机（虚拟主机配置文件的第一个），无论什么域名只要指向到这台机器就会访问到这个主机。其实，在 nginx 里也有这样的默认虚拟主机，但它是通过一个配置来标记哪个虚拟主机是默认的。

  在 nginx.conf 主配置文件的最后加入如下一行，表示启用虚拟主机。

[root@localhost ~]# vim /usr/local/nginx/conf/nginx.conf

server

{

    listen 80;

    server_name localhost;

    index index.html index.htm index.php;

    root /usr/local/nginx/html;



    location ~ \.php$ {

        include fastcgi_params;

        fastcgi_pass unix:/tmp/php-fcgi.sock;

        fastcgi_index index.php;

        fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;

    }



}

include /usr/local/nginx/conf/vhosts/*.conf;

}

  创建该目录和对应虚拟主机配置文件：

[root@localhost ~]# mkdir /usr/local/nginx/conf/vhosts

[root@localhost ~]# cd !$

cd /usr/local/nginx/conf/vhosts

[root@localhost vhosts]# vim default.conf

server

{

    listen 80 default_server;

    server_name test.com;

    index index.html index.htm index.php;

    root /tmp/tmp;

    deny all;

}

  这里通过 listen 80 后的 default_server 来确认默认虚拟主机，通过 deny all 来禁掉访问。

  创建一个可访问的虚拟主机：

  添加虚拟主机配置文件，和 apache 不一样的是，多个虚拟主机配置文件是分开写在对应目录下的多个文件中，而不是 apache 中一个文件的多个字段。

server

{

    listen 80;

    server_name 123.com www.123.com;

    index index.html index.htm index.php;

    root /usr/local/nginx/html;



    location ~ \.php$ {

        include fastcgi_params;

        fastcgi_pass unix:/tmp/php-fcgi.sock;

        fastcgi_index index.php;

        fastcgi_param SCRIPT_FILENAME /usr/local/nginx/html$fastcgi_script_name;

    }



}

  在对应目录中建立 index.php

  检查和重新加载

[root@localhost vhosts]# /usr/local/nginx/sbin/nginx -t

nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok

nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful

[root@localhost vhosts]# /usr/local/nginx/sbin/nginx -s reload

  修改 hosts 文件

[root@localhost vhosts]# vim /etc/hosts

127.0.0.1   localhost localhost.localdomain localhost4 localhost4.localdomain4

::1         localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.94.128 www.123.com www.test.com

  使用 curl 命令检测

[root@localhost vhosts]# curl www.123.com -I
