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
