docker 多应用 nginx 配置

2022-03-04   

nginx 基础

nginx 的两种安装方式

方式一：直接安装

sudo apt install nginx

该方式会安装到 /etc/nginx 目录下，目录如下图：

image-20230301144016714

其中 nginx.conf 是主要的 nginx 配置，其中会引用其它位置的 nginx 配置，一般用户会将自己的配置放到 sites-available 目录中，再用一个软链接到 sites-enabled 目录生效自己的配置。

方式二：编译安装

apt -y install gcc make libssl-dev zlib1g-dev libgd-dev libgeoip-dev libpcre2-dev libpcre3-dev # 安装必要依赖
wget http://nginx.org/download/nginx-1.22.2.tar.gz # 下载nginx源码包
tar -xvf nginx-1.22.2.tar.gz
cd nginx-1.22.2# 解压后进入到解压目录
./configure 
make && make install

nginx 被安装到 /usr/local/nginx ：

image-20230302175725784

配置文件在 conf 目录下：

image-20230302180321588

原本没有红框的文件夹，为了配置管理的方便，可以自己新建 sites-available 和 sites-enabled 文件夹，在外面的 nginx.conf 把自己的配置目录包含进去即可：

# nginx.conf
#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;

events {
    worker_connections  1024;
}

http {
    include       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  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;
    #keepalive_timeout  0;
    keepalive_timeout  65;

    include /usr/local/nginx/conf/sites-enabled/*;
}

nginx 重要配置介绍

场景描述

外界通过 80 和 443 访问，经过 Linux 主机的 nginx 反向代理到不同的 docker 应用容器中进行处理

Linux 主机 nginx 配置

应用 1 的 nginx 配置：

该应用通过域名 librariestoner.com 或 www.librariestoner.com 访问：

# sites-available/halo.conf
upstream halo {
  server 127.0.0.1:6080;
}
server {
  listen 80;
  listen [::]:80;
  server_name librariestoner.com www.librariestoner.com;
  client_max_body_size 1024m;
  return 301 https://$host$request_uri;
}

server {
    listen 443 ssl;
    listen [::]:443 ssl;
    server_name librariestoner.com www.librariestoner.com;

    client_max_body_size 1024m;

    ssl_certificate "cert/librariestoner/librariestoner.com_bundle.crt";

    ssl_certificate_key "cert/librariestoner/librariestoner.com.key";
    location / {
            proxy_pass http://halo;
            proxy_set_header HOST $host;
            proxy_set_header X-Forwarded-Proto $scheme;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
}

应用 2 的 nginx 配置：

该应用通过域名 app817.acapp.acwing.com.cn 访问：

# sites-available/acapp.conf
upstream acapp {
    server 127.0.0.1:7080;
}
server {
  listen 80;
  listen [::]:80;
  server_name app817.acapp.acwing.com.cn;
  client_max_body_size 1024m;
  return 301 https://$host$request_uri;
}

server {
    listen 443 ssl;
    listen [::]:443 ssl;
    server_name app817.acapp.acwing.com.cn;
    client_max_body_size 1024m;
    ssl_certificate "cert/app.pem";

    ssl_certificate_key "cert/app.key";
    location / {
            proxy_pass http://acapp;
            proxy_set_header HOST $host;
            proxy_set_header X-Forwarded-Proto $scheme;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    }
    location /wss {
        proxy_pass http://127.0.0.1:5015;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header Host $http_host;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

        proxy_http_version 1.1;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection "upgrade";
    }
}

注： https 要在最外层 nginx 配置中做。docker nginx 配置中只处理 80 端口。

docker1 nginx 配置

# sites-available/halo.conf
upstream halo {
  server 127.0.0.1:8090;
}
server {
  listen 80;
  listen [::]:80;
  server_name librariestoner.com www.librariestoner.com localhost;
  client_max_body_size 1024m;
  location / {
    proxy_pass http://halo;
    proxy_set_header HOST $host;
    proxy_set_header X-Forwarded-Proto $scheme;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
  }
}
