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:  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:  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
       valid_lft 988sec preferred_lft 988sec
    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:  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:  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
       valid_lft 6895sec preferred_lft 6895sec
    inet 192.168.1.125/24 scope global secondary enp0s3
       valid_lft forever preferred_lft forever
    inet6 fe80::e09e:e70e:87c8:45f2/64 scope link noprefixroute 
       valid_lft forever preferred_lft forever

1.2修改default.conf

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.conf

1.3server1.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




Welcome to nginx!



service1


mkdir /opt/app/server2
vi  /opt/app/server2/server2.html




Welcome to nginx!



service2

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))

server {
    listen      81;
    server_name  localhost;
    location / {
        root   /opt/app/server1;
        index  server2.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
