1.1.1. 什么是域名
域名就是网站。
Tcp/ip
Dns服务器：把域名解析为ip地址。保存的就是域名和ip的映射关系。
一级域名：
Baidu.com
Taobao.com
Jd.com
二级域名：
Image.baidu.com
Item.baidu.com
三级域名：
1.Image.baidu.com
Aaa.image.baidu.com
DNS服务器是专门解析域名的

一个域名对应一个ip地址，一个ip地址可以被多个域名绑定。
本地测试可以修改hosts文件。
修改window的hosts文件：（C:\Windows\System32\drivers\etc）
可以配置域名和ip的映射关系，如果hosts文件中配置了域名和ip的对应关系，不需要走dns服务器。
# Copyright (c) 1993-2009 Microsoft Corp.
#
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
#
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# space.
#
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
#
# For example:
#
# 102.54.94.97 rhino.acme.com # source server
# 38.25.63.10 x.acme.com # x client host
# localhost name resolution is handled within DNS itself.
# 127.0.0.1 localhost
# ::1 localhost

还有一个好用的工具SwitchHosts!.exe

本地的IP绑定域名设置
image.png
新建一个camel
image.png
绑定完ip和域名的对应关系之后
下一步 我们要在虚拟主机完成
cd /usr/local/nginx
找到-rw-r--r--. 1 root root 2656 7月 28 01:39 nginx.conf
添加server 配置相同的端口 ，但是server_name 为绑定的域名
server {
listen 80;
server_name wwww.camel.com;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root html-test1;
index index.html index.htm;
}
}
server {
listen 80;
server_name wwww.camel1.com;
#charset koi8-r;
#access_log logs/host.access.log main;
location / {
root html-test;
index index.html index.htm;
}
}
第一步 cd /usr/local/nginx/ 复制html
[root@Nigux nginx]# cp -r html html-test
[root@Nigux nginx]# cp -r html html-test1
区分两个不同的界面
drwxr-xr-x. 2 root root 4096 7月 29 23:06 conf
drwxr-xr-x. 2 root root 40 7月 28 01:39 html
drwxr-xr-x. 2 root root 40 7月 29 22:54 html81
drwxr-xr-x. 2 root root 40 7月 30 00:09 html-test
drwxr-xr-x. 2 root root 40 7月 30 00:09 html-test1
drwxr-xr-x. 2 root root 19 7月 28 01:39 sbin
[root@Nigux nginx]# vim html-test/index.html
[root@Nigux nginx]# vim html-test1/index.html
修改页面之后，shift+zz 保存退出后，重启一下服务
[root@Nigux nginx]# sbin/nginx -s reload
测试：
