1、基于域名的虚拟主机：
绝大多数企业对外提供服务的网站使用的都是基于域名的主机，通过不同的域名区分不同的虚拟主机。
首先我们进入安装nginxd的目录下：/application/nginx-1.6.3/conf
我们去除掉默认配置文件里的注释和空行并重定向到nginx.conf文件里，同时我们需要配置如下：
egrep -v "#|^$" nginx.conf.default >nginx.conf //去掉包含#号和空行的内容
[root@lamp01 conf]# vim nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name www.jyw1.com;
location / {
root html/www;
index index.html index.htm;
}
}
server {
listen 80;
server_name bbs.jyw2.com;
location / {
root html/bbs;
index index.html index.htm;
}
}
}
创建站点目录文件：
mkdir ../html/{www,bbs} -p
[root@lamp01 conf]# tree ../html/
../html/
├── 50x.html
├── bbs
│ └── index.html
├── index.html
└── www
└── index.html
为站点目录生成首页并追加内容：
通过hosts来做dns解析
[root@lamp01 conf]# echo "www.jyw1.com" >../html/www/index.html
[root@lamp01 conf]# echo "bbs.jyw2.com" >../html/bbs/index.html
[root@lamp01 conf]# cat ../html/{www,bbs}/index.html
www.jyw1.com
bbs.jyw2.com
[root@lamp01 conf]# /application/nginx/sbin/nginx -t #检查语法
nginx: the configuration file /application/nginx-1.6.3/conf/nginx.conf syntax is ok
nginx: configuration file /application/nginx-1.6.3/conf/nginx.conf test is successful
[root@lamp01 conf]# /application/nginx/sbin/nginx -s reload #刷新配置
[root@lamp01 conf]# vi /etc/hosts
[root@lamp01 conf]# ping www.jyw1.com

[root@lamp01 conf]# ping bbs.jyw2.com

[root@lamp01 conf]# curl www.jyw1.com
www.jyw1.com
[root@lamp01 conf]# curl bbs.jyw2.com
bbs.jyw2.com
[root@lamp01 conf]#
我是用的windows系统，配置一下host在“C:\Windows\System32\drivers\etc”下的hosts中配置一下域名重定向
192.168.43.118 www.jyw1.com bbs.jyw2.com
然后cmd再ping一下这个域名是否正确指向了这个IP上
打开浏览器，输入www.test.com会得到以下结果，就说明外网访问成功
ok，通过多域名来访问站点，同样也可以一个站点多个域名。
2.基于端口的虚拟主机配置：
此类型的虚拟主机主要应用于企业内部的网站，需要加端口号才能访问，通过不同的端口来区分不同的虚拟主机，为企业网站安全优化，例如：企业的网站后台，资料共享等。
在前面配置的基于域名的虚拟主机的基础上只需要修改nginx.conf文件，刷新配置即可完成：
修改nginx.conf配置文件
[root@lamp01 conf]# vim nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 8001;
server_name www.jyw1.com;
location / {
root html/www;
index index.html index.htm;
}
}
server {
listen 8002;
server_name bbs.jyw2.com;
location / {
root html/bbs;
index index.html index.htm;
}
}
}
刷新配置，测试结果如下
[root@lamp01 conf]# /application/nginx/sbin/nginx -t
nginx: the configuration file /application/nginx-1.6.3/conf/nginx.conf syntax is ok
nginx: configuration file /application/nginx-1.6.3/conf/nginx.conf test is successful
[root@lamp01 conf]# /application/nginx/sbin/nginx -s reload
[root@lamp01 conf]# curl www.jyw1.com
curl: (7) couldn‘t connect to host
[root@lamp01 conf]# curl www.jyw1.com:8001
www.jyw1.com
[root@lamp01 conf]# curl bbs.jyw2.com:8002
bbs.jyw2.com
[root@lamp01 conf]#
在windows下测试如下：
ok，既可以对应多个站点，多个端口访问，也可以对应一个站点多个端口访问。
3.基于IP地址虚拟主机：
通过不同的IP区分不同的虚拟主机，此类型企业应用于比较少，通常用到不通业务流中或者负载均衡上面。
在前面配置的基于域名的虚拟主机的基础上只需要修改nginx.conf文件，刷新配置即可完成：
修改nginx.conf配置文件
[root@lamp01 conf]# vim nginx.conf
worker_processes 1;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
sendfile on;
keepalive_timeout 65;
server {
listen 192.168.43.118:80;
server_name www.jyw1.com;
location / {
root html/www;
index index.html index.htm;
}
}
server {
listen 192.168.43.88:80;
server_name bbs.jyw2.com;
location / {
root html/bbs;
index index.html index.htm;
}
}
}
修改完配置文件后，我们需要虚拟一块网卡：
ip addr add //添加
ip addr del 192.168.43.88/24 dev eth0 //删除
临时性网卡： ip addr add 192.168.43.88/24 label eth0:1 dev eth0 或者 ifconfig eth0:1 192.168.43.88/24 up
[root@lamp01 conf]# ip addr add 192.168.43.88/24 label eth0:1 dev eth0 添加网卡（推荐使用ip addr）
[root@lamp01 conf]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:0C:29:01:4D:22
inet addr:192.168.43.118 Bcast:192.168.43.255 Mask:255.255.255.0
inet6 addr: fe80::20c:29ff:fe01:4d22/64 Scope:Link

UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
[root@lamp01 conf]# ip addr del 192.168.43.99/24 dev eth0 删除网卡
[root@lamp01 conf]# ifconfig
eth0 Link encap:Ethernet HWaddr 00:0C:29:01:4D:22
inet addr:192.168.43.118 Bcast:192.168.43.255 Mask:255.255.255.0
inet6 addr: fe80::20c:29ff:fe01:4d22/64 Scope:Link

collisions:0 txqueuelen:1000
RX bytes:103486 (101.0 KiB) TX bytes:83366 (81.4 KiB)
[root@lamp01 conf]#
永久性网卡：
cd /etc/sysconfig/network-scripts/ //进入到网卡配置文件的目录
cp ifcfg-eth0 ifcfg-eth0:1 //拷贝配置文件并重命名
vim ifcfg-eth0:1 //编辑配置文件
/etc/init.d/network restart //重启网络服务
图略....
下面我们刷新配置，查看效果：
[root@lamp01 ~]# /application/nginx/sbin/nginx -t
nginx: the configuration file /application/nginx-1.6.3/conf/nginx.conf syntax is ok
nginx: configuration file /application/nginx-1.6.3/conf/nginx.conf test is successful
[root@lamp01 ~]# /application/nginx/sbin/nginx -s reload
[root@lamp01 ~]# curl 192.168.43.88
bbs.jyw2.com
[root@lamp01 ~]# curl 192.168.43.118
www.jyw1.com
[root@lamp01 ~]#
在windows下测试如下：
ok，既可以多个IP对应一个站点，也可以对应多个站点访问。
