SSL Lab A+ – Docker LEMP 初级教程

萨摩的编排可以支持 TLS 1.3 + QUIC ，轻轻松松拿 SSL Lab A

首先是安装 docker-ce 和 docker-compose

curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh
curl -L "https://github.com/docker/compose/releases/download/1.23.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
sudo chmod +x /usr/local/bin/docker-compose

然后就是拉取萨摩的编排模板惹

git clone https://github.com/metowolf/docker-lemp.git && cd docker-lemp

接下来我们就可以调整编排的配置了

cp .env.example .env && cp docker-compose.example.yml docker-compose.yml

在 .env 文件中可以修改各种容器的版本还有 MySQL 的密码，在 docker-compose.yml 可以修改需要的容器

在这里我们一步到位，直接挂上 Nginx 的 brotli 模块

首先创建 nginx.conf 文件 (etc/nginx/nginx.conf)

user  nginx;
worker_processes  auto;

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

# 挂载 brotli 模块
load_module  modules/ngx_http_brotli_filter_module.so;
load_module  modules/ngx_http_brotli_static_module.so;

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;
}

然后创建 brotli 的配置文件 (etc/nginx/config/brotli.conf)

  brotli              on;
brotli_comp_level   6;
brotli_types        application/x-httpd-php application/javascript application/x-javascript application/xml application/json text/plain text/javascript text/css text/xml image/jpeg image/gif image/png image/svg+xml;

接下来在 docker-compose.yml 里挂载上 nginx.conf 就可以惹

brotli 弄好之后我们就开始弄网站配置了，下面是小霖博客用的 nginx 配置(伪静态是WordPress的)，其中第二个 add_header 是为了提醒浏览器尝试连接 443 udp 端口上的 Caddy 以使用 quic 服务，一会会写到哒

server {
    listen 443 ssl http2;

    server_name xiaolin.in;
    set $base /var/www/xiaolin.in;
    root $base;

  add_header Strict-Transport-Security "max-age=31536000; includeSubDomains; preload" always;
      add_header alt-svc 'quic=":443"; ma=2592000; v="44,43,39"';

    # SSL
    ssl_certificate /etc/nginx/ssl/_.xiaolin.in.crt;
    ssl_certificate_key /etc/nginx/ssl/_.xiaolin.in.key;


    # index.php
    index index.php;

    location / {
          # This is cool because no php is touched for static content.
          # include the "?$args" part so non-default permalinks doesn't break when using query string
          try_files $uri $uri/ /index.php?$args;
    }  


    # handle .php
    location ~ \.php$ {
          fastcgi_split_path_info ^(.+\.php)(/.+)$;
          fastcgi_pass php-fpm:9000;
          fastcgi_index index.php;
          include fastcgi_params;
          fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
          fastcgi_param PATH_INFO $fastcgi_path_info;
      }

  location ~ .*\.(gif|jpg|jpeg|png|bmp|swf|flv|mp4|ico)$ {
        expires 30d;
        access_log off;
    }
    location ~ .*\.(js|css)?$ {
        expires 7d;
        access_log off;
    }
    location ~ /\.ht {
        deny all;
    }
}

server {
  listen 80;
  listen [::]:80;

  server_name xiaolin.in;

  return 301 https://xiaolin.in$request_uri;
}

为了使用 quic 特性，我们需要用 Caddy 在 UDP 端口反代一下网站 (etc/nginx/caddy/Caddyfile)

https://xiaolin.in {

    gzip
    tls /ssl/_.xiaolin.in.crt /ssl/_.xiaolin.in.key

    proxy / https://nginx {
        insecure_skip_verify
        transparent
        websocket
    }
}

最后在 wwwroot/你的网站名 下放好程序就可以输入以下命令开始部署了

sudo docker-compose up -d

启动成功后如果不出意料的话就可以看见熟悉的界面了

尾声

MySQL 的话可能在小机机上需要添加 SWAP 内存，不然可能会爆 InnoDB: mmap(137363456 bytes) failed; errno 12 这种玩意儿

至于更新的话，萨摩自己都说了自己是「追新族」了hhh，那就不用担心容器太旧的问题了，至于更新的话，执行下面第一行代码修改后再执行第二行代码就可以了

git pull && cp .env.example .env && cp docker-compose.example.yml docker-compose.yml
sudo docker-compose up -d --no-deps --build
