场景: 一台服务上部署了n多个网站,假设 有 web1 web2 ,服务器的IP 是 192.168.1.10 ,web1 的访问地址 192.168.1.10:8080 ,web2 的访问地址 192.168.1.10:8081, 有一个域名 myhost.com , 当然你会绑定 IP myhost.com -> 192.168.1.10 这样,你就可以 myhost.com:8080 访问 web1 , myhost.com:8081 访问 web2 , 当然没有任何问题,

怎么才能不加端口号 也能访问不同的网站能, 答案肯定是没有问题的,可以解决.
使用不同的域名区分不同的网站,使用 nginx 代理

web1.myhost.com -> 192.168.1.10:8080
web2.myhost.com -> 192.168.1.10:8081

1. 拉取镜像

docker pull nginx

 

2. 获取配置文件

从镜像中获取

docker run --name tmp-nginx-container -d nginx
mkdir /etc/nginx
docker cp tmp-nginx-container:/etc/nginx/nginx.conf /etc/nginx/
docker stop tmp-nginx-container
docker rm tmp-nginx-container

 

3. 编辑配置文件

创建一配置文件
/etc/nginx/hosts.conf

server {
    listen       80;
    listen  [::]:80;
    server_name  web1.myhost.com;

    location / {
        proxy_pass http://192.168.1.10:8080/;
    }

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}

server {
    listen       80;
    listen  [::]:80;
    server_name  web2.myhost.com;

    location / {
        proxy_pass http://192.168.1.10:8081/;
    }

    error_page   500 502 503 504  /50x.html;
    location = /50x.html {
        root   /usr/share/nginx/html;
    }
}

 

修改 nginx.conf 指向 hosts.conf

nano /etc/nginx/nginx.conf

default_type  application/octet-stream;
user  nginx;
worker_processes  auto;

error_log  /var/log/nginx/error.log notice;
pid        /var/run/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       /etc/nginx/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"';

    access_log  /var/log/nginx/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    keepalive_timeout  65;

    #gzip  on;

    include /etc/nginx/hosts.conf; // 添加自定义配置

    include /etc/nginx/conf.d/*.conf;
}

 

4. 运行

docker run --name nginx -p 80:80 -v 
/etc/nginx/hosts.conf:/etc/nginx/hosts.conf:ro -v 
/etc/nginx/nginx.conf:/etc/nginx/nginx.conf:ro -d nginx

 

5. 测试
