默认虚拟主机
[root@lizhipenglinux01 conf]# curl localhost/1.php
This is nginx test page.[root@lizhipenglinux01 conf]# 
先来解释“虚拟主机”。在介绍httpd的时候，已经解释过默认虚拟主机的概念，在Nginx中也有默认虚拟主机，跟httpd类似，第一个被Nginx加载的虚拟主机就是默认主机。但和httpd不同的地方是，它还有一个配置用来标记默认虚拟主机。也就是说，如果没有这个标记，第一个虚拟主机默认虚拟主机。删除nginx.conf如下部分。
添加如下部分
意思是，/usr/local/nginx/conf/vhost/下面的所有以.conf结尾的文件都会加载，这样我们就可以把所有虚拟主机配置文件放到vhost目录下面
[root@lizhipenglinux01 conf]# pwd
/usr/local/nginx/conf
[root@lizhipenglinux01 conf]# mkdir vhost
[root@lizhipenglinux01 conf]# cd vhost/
[root@lizhipenglinux01 vhost]# ls
[root@lizhipenglinux01 vhost]# vim aaa.com.conf
server
{
    listen 80 default_server;  // 有这个标记的就是默认虚拟主机
    server_name aaa.com;
    index index.html index.htm index.php;         指定索引页
    root /data/wwwroot/default;
}
[root@lizhipenglinux01 vhost]# mkdir /data/wwwroot/default/
[root@lizhipenglinux01 vhost]# cd /data/wwwroot/default/
[root@lizhipenglinux01 default]# ls
[root@lizhipenglinux01 default]# vim index.html
This is the default site.
[root@lizhipenglinux01 default]# /usr/local/nginx/sbin/nginx -t       检查有没有语法错误
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@lizhipenglinux01 default]# /usr/local/nginx/sbin/nginx -s reload   重新加载
[root@lizhipenglinux01 default]# curl localhost
This is the default site.
[root@lizhipenglinux01 default]# curl -x127.0.0.1:80 bbb.com
This is the default site.
[root@lizhipenglinux01 default]# curl -x127.0.0.1:80 aaa.com
This is the default site.
[root@lizhipenglinux01 default]# vim /usr/local/nginx/conf/vhost/test.com.conf
server
{
    listen 80;
    server_name test.com;
    index index.html index.htm index.php;
    root /data/wwwroot/test.com;
    
location  /
    {
        auth_basic              "Auth";     定义用户认证的名字
        auth_basic_user_file   /usr/local/nginx/conf/htpasswd;     用户名密码文件
}
}
 
[root@lizhipenglinux01 default]# vim /usr/local/nginx/conf/vhost/test.com.conf
[root@lizhipenglinux01 default]# /usr/local/apache2.4/bin/htpasswd -c /usr/local/nginx/conf/htpasswd aming
New password: 
Re-type new password: 
Adding password for user aming
[root@lizhipenglinux01 default]# /usr/local/apache2.4/bin/htpasswd /usr/local/nginx/conf/htpasswd user1    第二个的时候不要-c，-c表示生成，会重置之前的
New password: 
Re-type new password: 
Adding password for user user1
[root@lizhipenglinux01 default]# cat /usr/local/nginx/conf/htpasswd
aming:$apr1$tmIuz3nE$1j60Dm8yXQkDEJtWnF5s31
user1:$apr1$erglUoeF$vY7Rnm9/A12JjRoc0fM4d.
[root@lizhipenglinux01 default]# /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@lizhipenglinux01 default]# /usr/local/nginx/sbin/nginx -s reload
这个是针对目录的
[root@lizhipenglinux01 default]# /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@lizhipenglinux01 default]# /usr/local/nginx/sbin/nginx -s reload
这个时候连接test.com不需要密码，但是/admin目录下 需要
[root@lizhipenglinux01 default]# curl -uaming:lizhipeng -x127.0.0.1:80 test.com/admin/         
test.com admin dir
并不需要-u
[root@lizhipenglinux01 default]# curl -x127.0.0.1:80 test.com/admin.php        这个就需要了
<html>
<head><title>401 Authorization Required</title></head>
<body bgcolor="white">
<center><h1>401 Authorization Required</h1></center>
<hr><center>nginx/1.12.1</center>
</body>
</html>
test4.com会去访问默认的虚拟主机
