什么是虚拟主机？
虚拟主机是一种特殊的软硬件技术，它可以将网络上的每一台计算机分成多个虚拟主机，每个虚拟主机可以独立对外提供www服务，这样就可以实现一台主机对外提供多个web服务，每个虚拟主机之间是独立的，互不影响。

nginx可以实现虚拟主机的配置，nginx支持三种类型的虚拟主机配置。
1、基于域名的虚拟主机 （server_name来区分虚拟主机——应用：外部网站）
2、基于ip的虚拟主机， （一块主机绑定多个ip地址）
3、基于端口的虚拟主机 （端口来区分虚拟主机——应用：公司内部网站，外部网站的管理后台）
1、 基于域名的虚拟主机
1、配置通过域名区分的虚拟机
[root@localhost ~]# cat /etc/nginx/nginx.conf
worker_processes 4;
#error_log logs/error.log;
worker_rlimit_nofile 102400;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
server {
listen 80;
server_name www.biudefor.com; #域名
location / {
root /var/www/nginx/; #html文件存放目录
index index.html index.htm; #文件名
limit_rate 2k;
}
}
server {
listen 80;
server_name www.goodboy.com;
location / {
root /tmp/html;
index index.html index.htm;
}
}
}
为域名对应的主机配置index.html文件
[root@localhost ~]# mkdir -p /tmp/html
[root@localhost ~]# mkdir -p /var/www/nginx
[root@localhost ~]# vim /tmp/html/index.html
<html>
<p>
this is my goodboy server
</p>
</html>
[root@localhost ~]# vim /var/www/nginx/index.html
<html>
<p>
this is my biudefor server
</p>
</html>
3、重新加载配置文件
# 如果编译安装的执行
[root@nginx]# /usr/local/nginx/sbin/nginx -s reload
# 如果 yum 安装的执行
[root@nginx]# nginx -s reload
4、客户端配置路由映射(域名解析)
在 C:\Windows\System32\drivers\etc\hosts 文件中添加两行(linux:/etc/hosts)
10.0.105.199 web.testpm.com
10.0.105.199 web.1000phone.com
5、 测试访问
浏览器输入：www.biudefor.com
浏览器输入：www.goodboy.com
2、 基于ip的虚拟主机
[root@localhost ~]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN qlen 1
link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 ::1/128 scope host
valid_lft forever preferred_lft forever
2: ens33: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 00:0c:29:17:f1:af brd ff:ff:ff:ff:ff:ff
inet 10.0.105.199/24 brd 10.0.105.255 scope global dynamic ens33
valid_lft 81438sec preferred_lft 81438sec
inet6 fe80::9d26:f3f0:db9c:c9be/64 scope link
valid_lft forever preferred_lft forever
[root@localhost ~]# ifconfig ens33:1 10.0.105.201/24
[root@localhost ~]# ifconfig
ens33: flags=4163<UP,BROADCAST,RUNNING,MULTICAST> mtu 1500
inet 10.0.105.199 netmask 255.255.255.0 broadcast 10.0.105.255

ether 00:0c:29:17:f1:af txqueuelen 1000 (Ethernet)
2、配置通过ip区分的虚拟机
[root@localhost ~]# cat /etc/nginx/nginx.conf
user root;
worker_processes 4;
#error_log logs/error.log;
worker_rlimit_nofile 102400;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
server {
listen 10.0.105.199:80;
server_name web.testpm.com;
location / {
root /var/www/nginx/;
index index.html index.htm;
limit_rate 2k;
}
server {
listen 10.0.105.201:80;
server_name web.testpm.com;
location / {
root /1000phone/html/;
index index.html index.htm;
}
}
}
3、重新加载配置文件
[root@localhost ~]# /usr/local/nginx/sbin/nginx -s reload
4、 测试访问
浏览器输入：http://10.0.105.199
浏览器输入：http://10.0.105.201
5、补充
-- 删除绑定的vip
[root@localhost ~]# ifconfig ens33:1 10.0.105.201/24 down
重启一下nginx
[root@localhost ~]# systemctl restart nginx
3、 基于端口的虚拟主机
[root@localhost ~]# cat /etc/nginx/nginx.conf
user root;
worker_processes 4;
worker_rlimit_nofile 102400;
events {
worker_connections 1024;
}
http {
include mime.types;
default_type application/octet-stream;
log_format main '$remote_addr - $remote_user [$time_local] "$request" '
'$status $body_bytes_sent "$http_referer" '
'"$http_user_agent" "$http_x_forwarded_for"';
sendfile on;
keepalive_timeout 65;
server {
listen 80;
server_name www.goodboy.com;
location / {
root /var/www/nginx/;
index index.html index.htm;
limit_rate 2k;
}
server {
listen 8080;
server_name www.biudefor.com;
location / {
root /tmp/html/;
index index.html index.htm;
}
}
}
重新加载配置文件:
[root@localhost ~]# /usr/local/nginx/sbin/nginx -s reload
测试访问:
浏览器输入：http://www.goodboy.com/
浏览器输入：http://www.biudefor.com:8080
