Nginx虚拟主机

一 虚拟主机

1.1 虚拟主机概念

对于Nginx而言，每一个虚拟主机相当于一个在同一台服务器中却相互独立的站点，从而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，互不影响的。

1.2 虚拟主机类型

通过 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：

• 基于 IP 的虚拟主机（较少使用）
• 基于域名的虚拟主机
• 基于端口的虚拟主机

二 基于IP虚拟主机

2.1 配置多IP地址

[root@master ~]# ifconfig ens33:0 192.168.1.221 broadcast 192.168.1.255 netmask 255.255.255.0
[root@master ~]# ip add |grep 192
    inet 192.168.1.220/24 brd 192.168.1.255 scope global noprefixroute ens33
    inet 192.168.1.221/24 brd 192.168.1.255 scope global secondary ens33:0

提示：如上在同一台主机添加多个IP地址。

2.2 创建站点目录

[root@master ~]# mkdir /usr/share/nginx/ipvhost01/
[root@master ~]# mkdir /usr/share/nginx/ipvhost02/
[root@master ~]# echo '<h1>Ipvhost01</h1>' > /usr/share/nginx/ipvhost01/index.html
[root@master ~]# echo '<h1>Ipvhost02</h1>' > /usr/share/nginx/ipvhost02/index.html

2.3 配置虚拟主机

[root@master ~]# vi /etc/nginx/conf.d/ipvhost01.conf
server {
    listen  80;                 #监听端口
    server_name   192.168.1.220;        #配置虚拟主机名和IP
    location / {
        root   /usr/share/nginx/ipvhost01;              #请求匹配路径
        index  index.html;                              #指定主页
        access_log  /var/log/nginx/ipvhost01.access.log  main;
        error_log   /var/log/nginx/ipvhost01.error.log  warn;
    }
}
server {
    listen  80;
    server_name  192.168.1.221;
    location / {
        root   /usr/share/nginx/ipvhost02;
        index  index.html;
        access_log  /var/log/nginx/ipvhost02.access.log  main;
        error_log   /var/log/nginx/ipvhost02.error.log  warn;
    }
}

[root@master ~]# nginx -t -c /etc/nginx/nginx.conf
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@master ~]# nginx -s reload

2.4 确认验证

 

三 基于域名虚拟主机

3.1 创建站点目录

[root@master ~]# mkdir /usr/share/nginx/webvhost01/
[root@master ~]# mkdir /usr/share/nginx/webvhost02/
[root@master ~]# echo '<h1>Webvhost01</h1>' > /usr/share/nginx/webvhost01/index.html
[root@master ~]# echo '<h1>Webvhost02</h1>' > /usr/share/nginx/webvhost02/index.html

3.2 配置虚拟主机

[root@master ~]# vi /etc/nginx/conf.d/webvhost.conf
server {
    listen  80;
    server_name  webvhost01.odocker.com;
    location / {
        root   /usr/share/nginx/webvhost01;
        index  index.html;
        access_log  /var/log/nginx/webvhost01.access.log  main;
        error_log   /var/log/nginx/webvhost01.error.log  warn;
    }
}
server {
    listen  80;
    server_name  webvhost02.odocker.com;
    location / {
        root   /usr/share/nginx/webvhost02;
        index  index.html;
        access_log  /var/log/nginx/webvhost02.access.log  main;
        error_log   /var/log/nginx/webvhost02.error.log  warn;
    }
}

[root@master ~]# nginx -t -c /etc/nginx/nginx.conf
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@master ~]# nginx -s reload

3.3 确认验证

[root@master ~]# curl webvhost01.odocker.com
<h1>Webvhost01</h1>
[root@master ~]# curl webvhost02.odocker.com
<h1>Webvhost02</h1>

四 基于端口虚拟主机

4.1 创建站点目录

[root@master ~]# mkdir /usr/share/nginx/portvhost01/
[root@master ~]# mkdir /usr/share/nginx/portvhost02/
[root@master ~]# echo '<h1>Portvhost01</h1>' > /usr/share/nginx/portvhost01/index.html
[root@master ~]#  echo '<h1>Portvhost01</h1>' > /usr/share/nginx/portvhost02/index.html

[root@master ~]# vi /etc/nginx/conf.d/portvhost.conf
server {
    listen  8080;
    server_name  portvhost01.odocker.com;
    location / {
        root   /usr/share/nginx/portvhost01;
        index  index.html;
        access_log  /var/log/nginx/portvhost01.access.log  main;
        error_log   /var/log/nginx/portvhost01.error.log  warn;
    }
}
server {
    listen  8081;
    server_name  portvhost02.odocker.com;
    location / {
        root   /usr/share/nginx/portvhost02;
        index  index.html;
access_log  /var/log/nginx/access_portvhost02.log  main;
    }
}
~

[root@master ~]# nginx -t -c /etc/nginx/nginx.conf
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful
[root@master ~]# nginx -s reload

3.3 确认验证

[root@master ~]# curl portvhost01.odocker.com:8080
<h1>Portvhost01</h1>
[root@master ~]# curl portvhost02.odocker.com:8081
<h1>Portvhost01</h1>
