安装 nginx 进行反向代理和端口转发。在进行之前确保 Docker 已经安装。

准备工作

先找个目录放 nginx 的配置文件。我在用户目录下面准备了一块地方来专门放这些文件。你也可以找个你熟悉的位置。

$ mkdir -p /etc/homelab/nginx

$ mkdir -p /etc/homelab/nginx/conf.d

$ cd /etc/homelab/nginx

接着准备一份配置文件模版。

$ docker run --name tmp-nginx-container -d nginx

$ docker cp tmp-nginx-container:/etc/nginx/nginx.conf nginx.conf

$ docker cp tmp-nginx-container:/etc/nginx/conf.d/example.conf conf.d/homelab.conf

$ docker rm -f tmp-nginx-container

来看看这个模版的内容。

$ cat nginx.conf

user  nginx;
worker_processes  1;

error_log  /var/log/nginx/error.log warn;
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/conf.d/*.conf;
}

nginx config

server {
    listen 80 default_server;
    listen [::]:80 default_server;
    root /var/www/example.com;
    index index.html;
    server_name example.com;
}

For blog.example.com subdomain

server {
    listen 80;
    listen [::]:80;
    root /var/www/blog.example.com;
    index index.html;
    server_name blog.example.com;
}

For fake.com domain

server {
    listen 80;
    listen [::]:80;
    root /var/www/fake.com;
    index index.html;
    server_name fake.com;

systemctl start firewalld.service

关闭防火墙：

systemctl stop firewalld.service

重启防火墙：

systemctl restart firewalld.service

开机启用防火墙：

systemctl enable firewalld.service

开机禁用防火墙：

systemctl disable firewalld.service

查看防火墙状态：

systemctl status firewalld.service

查看端口：

firewall-cmd --zone=public --list-ports

添加端口：

firewall-cmd --permanent --zone=public --add-port=8080/tcp

删除端口：

firewall-cmd --permanent --zone=public --remove-port=8080/tcp

重新加载防火墙规则：

firewall-cmd --reload

Get local ip

ifconfig wlp2s0 | grep inet | grep -v inet6 | awk '{print $2}'

Set up ssl

sudo certbot certonly -d *.bizcat.xyz,bizcat.xyz --manual --preferred-challenges dns --server https://acme-v02.api.letsencrypt.org/directory
