系统环境：
[root@localhost ~]# cat /etc/redhat-release CentOS Linux release 7.2.1511 (Core)
一、配置基于IP的虚拟主机
1、配置网卡IP，先查看本地虚拟机ip地址，物理机IP是：192.168.80.1
[root@localhost ~]# cat /etc/sysconfig/network-scripts/ifcfg-eno16777736 TYPE="Ethernet" BOOTPROTO="static" NAME="eno16777736" DEVICE="eno16777736" ONBOOT="yes" IPADDR=192.168.80.10 NETMASK=255.255.255.0 GATEWAY=192.168.80.2 DNS1=192.168.1.1
2、在我的虚机网卡eno16777736（centos6的网卡名字是eth0）设备上添加另外两个IP别名，192.168.80.11和192.168.80.12
[root@localhost ~]# vim /etc/sysconfig/network-scripts/ifcfg-eno16777736:0
TYPE=Ethernen TPROTO=static NAME=eno16777736:0 DEVICE=eno16777736:0 ONBOOT=yes IPADDR=192.168.80.11 NETMASK=255.255.255.0 GATEWAY=192.168.80.2
[root@localhost ~]# vim /etc/sysconfig/network-scripts/ifcfg-eno16777736:1
TYPE=Ethernen OTO=static NAME=eno16777736:1 DEVICE=eno16777736:1 ONBOOT=yes IPADDR=192.168.80.12 NETMASK=255.255.255.0 GATEWAY=192.168.80.2
修改完，重启网络服务
[root@localhost ~]# systemctl restart network
3、查看确认：
[root@localhost ~]# ip add
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN
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: eno16777736: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP qlen 1000
link/ether 00:0c:29:38:cf:ef brd ff:ff:ff:ff:ff:ff
inet 192.168.80.10/24 brd 192.168.80.255 scope global eno16777736
valid_lft forever preferred_lft forever
inet 192.168.80.11/24 brd 192.168.80.255 scope global secondary eno16777736:0
valid_lft forever preferred_lft forever
inet 192.168.80.12/24 brd 192.168.80.255 scope global secondary eno16777736:1
valid_lft forever preferred_lft forever
4、ping测试正常
[root@localhost ~]# ping 192.168.80.11 PING 192.168.80.11 (192.168.80.11) 56(84) bytes of data. 64 bytes from 192.168.80.11: icmp_seq=1 ttl=64 time=0.032 ms 64 bytes from 192.168.80.11: icmp_seq=2 ttl=64 time=0.042 ms ^C --- 192.168.80.11 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 1014ms rtt min/avg/max/mdev = 0.032/0.037/0.042/0.005 ms [root@localhost ~]# ping 192.168.80.12 PING 192.168.80.12 (192.168.80.12) 56(84) bytes of data. 64 bytes from 192.168.80.12: icmp_seq=1 ttl=64 time=0.058 ms 64 bytes from 192.168.80.12: icmp_seq=2 ttl=64 time=0.046 ms ^C --- 192.168.80.12 ping statistics --- 2 packets transmitted, 2 received, 0% packet loss, time 999ms
二、yum 安装nginx
1、如果默认yum install -y niginx安装不成功就先配置yum源，否则跳过。

[root@localhost ~]# vim /etc/yum.repos.d/epel.repo
[epel] name=aliyun epel baseurl=http://mirrors.aliyun.com/epel/7Server/x86_64/ gpgcheck=0
2、修改nginx配置文件，默认路径是 /etc/nginx/nginx.conf（主要是黑色粗体的配置，其他不写都可以）
[root@localhost ~]# vim /etc/nginx/nginx.conf
默认IP 192.168.80.10的nginx配置
server {
listen 80;
server_name _;
root /usr/share/nginx/html; #网页文件存放的目录
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
location / {
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
添加server1 192.168.80.11的nginx配置
server { listen 80;
server_name 192.168.80.11;
root /usr/share/nginx/server1; #网页文件存放的目录
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
location / {
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
添加server2 192.168.80.12的nginx配置
server {
listen 80;
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
location / {
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
listen 80;
server_name 192.168.80.12;
root /usr/share/nginx/server2; #网页文件存放的目录
# Load configuration files for the default server block.
include /etc/nginx/default.d/*.conf;
location / {
}
error_page 404 /404.html;
location = /40x.html {
}
error_page 500 502 503 504 /50x.html;
location = /50x.html {
}
}
启动服务
[root@localhost ~]# systemctl start nginx
3、添加另外两个新增IP的nginx页面。新建server*目录，然后拷贝默认目录html里面的文件到新目录并修改网页头部内容以便区分。
server1
[root@localhost nginx]# mkdir server1 [root@localhost nginx]# cp -R html/* server1/ [root@localhost server1]# vim index.html
修改各自目录下的index.html
77 <h1>Welcome to <strong>server1</strong> on Fedora!</h1>
server2
[root@localhost nginx]# mkdir server2 [root@localhost nginx]# cp -R html/* server2/ [root@localhost server2]# vim index.html
修改各自目录下的index.html
77 <h1>Welcome to <strong>server2</strong> on Fedora!</h1>
三、重启服务并查看
[root@localhost ~]# systemctl restart network [root@localhost ~]# systemctl restart nginx
网页访问成功！
