1.主机多Ip
1.1单网卡多ip主机配置
# 查看网络信息 1: lo: 本地 2: enp0s3:添加ip的网卡位置,名字可能不一样
# inet 192.168.1.124 虚拟机ip
[root@localhost html]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
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: enp0s3: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc pfifo_fast state UP group default qlen 1000
link/ether 08:00:27:8a:00:a7 brd ff:ff:ff:ff:ff:ff
inet 192.168.1.124/24 brd 192.168.1.255 scope global noprefixroute dynamic enp0s3

inet6 fe80::e09e:e70e:87c8:45f2/64 scope link noprefixroute
valid_lft forever preferred_lft forever
# 对于 enp0s3 添加另外的ip/掩码，添加的ip在局域网内不能被使用的，不确定可以使用ping命令
ip a add 192.168.1.125/24 dev enp0s3
# ip a 可以看到多了一个地址
[root@localhost html]# ip a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000

cd /etc/nginx/conf.d/
# 备份
cp default.conf /opt/backup/default.conf
# 重命名default名称
mv default.conf server1.conf
# 复制一份
cp server1.conf server2.conf
vi /etc/nginx/conf.d/server1.conf
vi /etc/nginx/conf.d/server2.conf1.3server1.conf
server {
listen 192.168.1.124:80;
server_name localhost;
location / {
root /opt/app/server1;
index server2.html;
}
error_page 500 502 503 504 /50x.html;
error_page 404 /404x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
location = /404x.html {
root /usr/share/nginx/html;
}
}
1.3server2.conf
server {
listen 192.168.1.125:80;
server_name localhost;
location / {
root /opt/app/server2;
index server2.html;
}
error_page 500 502 503 504 /50x.html;
error_page 404 /404x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
location = /404x.html {
root /usr/share/nginx/html;
}
}1.4测试文件
mkdir /opt/app/server1
vi /opt/app/server1/server1.html<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
html { color-scheme: light dark; }
body { width: 35em; margin: 0 auto;
font-family: Tahoma, Verdana, Arial, sans-serif; }
</style>
</head>
<body>
<h1>service1</h1>
</body>
</html>
mkdir /opt/app/server2
vi /opt/app/server2/server2.html
<!DOCTYPE html>
<html>
<head>
<title>Welcome to nginx!</title>
<style>
html { color-scheme: light dark; }
body { width: 35em; margin: 0 auto;
font-family: Tahoma, Verdana, Arial, sans-serif; }
</style>
</head>
<body>
<h1>service2</h1>
</body>
</html>1.4重启测试
systemctl restart nginx.service http://192.168.1.125/ http://192.168.1.124/
2.主机多端口
# 文件在下面
vi /etc/nginx/conf.d/server1.conf
vi /etc/nginx/conf.d/server2.conf
firewall-cmd --zone=public --add-port=81/tcp --permanent
firewall-cmd --zone=public --add-port=82/tcp --permanent
firewall-cmd --reload
# 检查配置文件语法是否正确
nginx -tc /etc/nginx/nginx.conf
# 重启nginx
sudo systemctl restart nginx.service
http://192.168.1.124:81
http://192.168.1.124:82
# 查看再用的端口
ss -luntp
cp LISTEN 0 128 *:81 *:* users:(("nginx",pid=1700,fd=6),("nginx",pid=1699,fd=6))
tcp LISTEN 0 128 *:82 
2.1server1.conf
server {
listen 81;
server_name localhost;
location / {
root /opt/app/server1;
index server2.html;
}
error_page 500 502 503 504 /50x.html;
error_page 404 /404x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
location = /404x.html {
root /usr/share/nginx/html;
}
}
2.2server2.conf
server {
listen 82;
server_name localhost;
location / {
root /opt/app/server2;
index server2.html;
}
error_page 500 502 503 504 /50x.html;
error_page 404 /404x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
location = /404x.html {
root /usr/share/nginx/html;
}
}3.多域名代理
# 修改主机host文件
192.168.1.124 1.nginx.cn
192.168.1.124 2.nginx.cn
# Win+R->C:\windows\System32\drivers\etc
# 记事本管理员权限,编辑hosts文件粘贴在最下面即可，或者复制到桌面然后在复制进去即可
# 文件在下面
vi /etc/nginx/conf.d/server1.conf
vi /etc/nginx/conf.d/server2.conf
# 检查配置文件语法是否正确
[root@localhost ~]# nginx -tc /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
# 重启nginx
sudo systemctl restart nginx.service
1.nginx.cn
2.nginx.cn
3.1server1.conf
server {
listen 80;
server_name 1.nginx.cn;
location / {
root /opt/app/server1;
index server2.html;
}
error_page 500 502 503 504 /50x.html;
error_page 404 /404x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
location = /404x.html {
root /usr/share/nginx/html;
}
}
3.2server2.conf
server {
listen 80;
server_name 2.nginx.cn;
location / {
root /opt/app/server2;
index server2.html;
}
error_page 500 502 503 504 /50x.html;
error_page 404 /404x.html;
location = /50x.html {
root /usr/share/nginx/html;
}
location = /404x.html {
root /usr/share/nginx/html;
}
}
