使用 docker-compose 和 nginx 在子目录中安装 wordpress

Question

我打算用docker-compose建一个网站。

当用户进入根目录时，它会转到 web 应用程序。 当用户输入http://example.com/blog时，它应该重定向到 wordpress。

为此，我已经像这样配置了 docker-compose

version: "3"

services:

  nginx:
    image: nginx:latest
    depends_on:
      - web-app
      - wordpress
    volumes:
      - ./nginx/nginx.conf:/etc/nginx/nginx.conf
    ports:
      - 80:80

  mysql:
    image: mysql:5.7.29
    container_name: mysql
    restart: always
    volumes:
      - ./data/mysql/data:/var/lib/mysql

  wordpress:
    depends_on:
      - mysql
    image: wordpress:latest
    ports:
      - 8000:80
    restart: always
    volumes:
     - ./data/blog:/var/www/html/wp-content
     - ./blog/wp-config.php:/var/www/html/wp-config.php

  web-app:
    build: ./app
    depends_on:
      - mysql
    restart: always
    command: npm start
    environment:
      - TZ=UTC
      - NODE_ENV=production

networks:
  default:
    external:
      name: common

这是我的 nginx 配置

worker_processes auto;
events {
    worker_connections 1024;
}
http {
    include /etc/nginx/mime.types;
    default_type application/octet-stream;
    log_format main '[$time_local] $remote_addr - $request request_time: $request_time';
    access_log /var/log/nginx/access.log main;

    gzip on;
    gzip_http_version 1.1;
    gzip_vary on;
    gzip_comp_level 6;
    gzip_proxied any;
    gzip_types text/plain text/html text/css application/json application/javascript application/x$
    #                        make sure gzip does not lose large gzipped js or css files
    #                        see http://blog.leetsoft.com/2007/07/25/nginx-gzip-ssl.html
    gzip_buffers 16 8k;

    server {
        listen 80;
        charset utf-8;

        location /blog/ {
            proxy_set_header  Host               $host;
            proxy_set_header  X-Real-IP          $remote_addr;
            proxy_set_header  X-Forwarded-For    $proxy_add_x_forwarded_for;

            proxy_pass http://wordpress;
        }

        location / {
            proxy_http_version 1.1;
            proxy_set_header X-Real-IP $remote_addr;
            proxy_set_header Upgrade $http_upgrade;
            proxy_set_header Connection "upgrade";
            proxy_set_header Host $http_host;
            proxy_set_header X-NginX-Proxy true;
            proxy_redirect off;
            proxy_pass http://web-app:3000;
        }

    }
} 

我已经更新了 wp-config.php 并设置了网站 url。

define('WP_SITE_URL', 'https://example.com/blog');
define('WP_SITEURL', 'https://example.com/blog');
define('WP_HOME', 'https://example.com/blog');

但是，当我进入https://example.com/blog时，它返回ERR_TOO_MANY_REDIRECTS响应。

我搜索了很多文章，其中一些说这是因为我使用的是 cloudflare。 我该如何解决上述问题？

Answer 1

在你的 config.php 你这样做：

// Define the website URL
define('WP_SITEURL', getenv_docker('WORDPRESS_SITEURL', 'https://example.com/blog'));

// Define the website Home page
define('WP_HOME',    getenv_docker('WORDPRESS_HOME', 'https://example.com/blog'));

在文件 docker-compose.yml 中放置以下环境变量：

environment:
  ...
  - WORDPRESS_SITEURL="https://example.com/blog"
  - WORDPRESS_HOME="https://example.com/blog"

Answer 2

要在/blog等子目录中初始化Wordpress ，您可以使用working_dir属性。

默认的Wordpress镜像使用/var/www/html作为root ，此时您可以移动到/var/www/html/blog进行初始化。

# ...
  wordpress:
    image: wordpress:apache
    working_dir: /var/www/html/blog
    volumes:
      - ./data/blog:/var/www/html/blog/wp-content
      - ./blog/wp-config.php:/var/www/html/blog/wp-config.php
# ...

现在，您可以导航到http://localhost/blog 。

以下是完整的docker-compose.yml示例：

version: '3.1'

x-wordpress: &wordpress
  depends_on:
    - db
  environment:
    WORDPRESS_DB_HOST: db:3306
    WORDPRESS_DB_NAME: wordpress
    WORDPRESS_DB_USER: wordpress
    WORDPRESS_DB_PASSWORD: wordpress
  working_dir: /var/www/html/blog
  volumes:
    - wp_root:/var/www/html/blog
    - ./wp-content/plugins:/var/www/html/blog/wp-content/plugins
    - ./wp-content/themes:/var/www/html/blog/wp-content/themes
    - ./wp-content/uploads:/var/www/html/blog/wp-content/uploads
    - ./wp-content/languages:/var/www/html/blog/wp-content/languages

services:
  # Database
  db:
    image: mysql:5.7
    volumes:
      - db_data:/var/lib/mysql
      - ./backup/blog.sql:/docker-entrypoint-initdb.d/dump.sql:ro
    ports:
      - 3306:3306
    environment:
      MYSQL_ROOT_PASSWORD: password
      MYSQL_DATABASE: wordpress
      MYSQL_USER: wordpress
      MYSQL_PASSWORD: wordpress

  # phpmyadmin
  phpmyadmin:
    depends_on:
      - db
    image: phpmyadmin/phpmyadmin
    ports:
      - 8080:80
    environment:
      PMA_HOST: db
      MYSQL_ROOT_PASSWORD: password

  # Wordpress
  wordpress:
    <<: *wordpress
    image: wordpress:apache
    ports:
      - 80:80

  wpcli:
    <<: *wordpress
    image: wordpress:cli

volumes:

Answer 3

实际上对我有用的是这个组合：

nginx：

upstream test {
    least_conn;
    server test_wordpress_1;
}
server {
    listen 443 ssl;
    server_name slapps.fr;
    #...
    #SSL CONFIG
    #...
    location /test/ {
        #rewrite ^/test/(.*)$ /$1 break; #This didn't work for me 
        proxy_set_header  Host               $host;
        proxy_set_header  X-Real-IP          $remote_addr;
        proxy_set_header  X-Forwarded-For    $proxy_add_x_forwarded_for;
        proxy_set_header  X-Forwarded-Proto  $scheme;
        proxy_pass http://test/;

    }
 }

wp-config.php：

define('WP_HOME','https://slapps.fr/test');
define('WP_SITEURL','https://slapps.fr/test');
$_SERVER['REQUEST_URI'] = str_replace("/wp-admin/", "/test/wp-admin/",  $_SERVER['REQUEST_URI']);

不知何故，docker-compose.yml 中的以下配置对我不起作用， $_SERVER 不会 go 通过，但第一个定义确实

WORDPRESS_CONFIG_EXTRA: |
            define( 'WP_HOME', 'https://slapps.fr/test' );
            define( 'WP_SITEURL', 'https://slapps.fr/test' );
            $$_SERVER['REQUEST_URI'] = str_replace("/wp-admin/", "/test/wp-admin/",  $$_SERVER['REQUEST_URI']);
