通过域名区分不同的虚拟主机

1.1.1. 什么是域名

域名就是网站。

www.baidu.com

www.taobao.com

www.jd.com

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：

www.baidu.com

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，假如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#

还有一个好用的工具SwitchHosts!.exe

本地的IP绑定域名设置

新建一个camel

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
增加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 confdrwxr-xr-x. 2 root root   40 7月  28 01:39 htmldrwxr-xr-x. 2 root root   40 7月  29 22:54 html81drwxr-xr-x. 2 root root   40 7月  30 00:09 html-testdrwxr-xr-x. 2 root root   40 7月  30 00:09 html-test1drwxr-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
