记录使用docker-compose搭建wordpress站点的过程（站点目前已使用Vuepress重新构建)。

---

服务器环境

• 云服务器 腾讯云主机

• 操作系统 Ubuntu Server 20.04 LTS

---

docker环境

• Docker Engine - Community 20.10.14

• Docker Compose - v2.2.3

---

docker-compose配置

• 目录准备

mkdir wordpress && cd wordpress && touch docker-compose.yml && mkdir volumes

在shell中输入以上命令：创建wordpress工作目录，并在其中创建docker-compose.yml(用于启动容器集群)，创建一个volumes目录用于容器配置文件挂载到宿主机

• 创建并编辑docker-compose.yml

sudo vi docker-compose.yml

粘贴如下配置内容，镜像包括 mysql、phpmyadmin、wordpress、nginx。其中phpmyadmin为数据库管理软件，不是必须的。

version: "3.9"
services:
 db:
   image: mysql
   volumes:
     - ./volumes/database:/var/lib/mysql
   restart: always
   environment:
     MYSQL_ROOT_PASSWORD: password
     MYSQL_DATABASE: wordpress
     MYSQL_USER: wordpress
     MYSQL_PASSWORD: password
 phpmyadmin:
   image: phpmyadmin
   depends_on:
     - db
   ports:
     - "8081:80"
   environment:
     PMA_HOST: db
 wordpress:
   depends_on:
     - db
   image: wordpress
   volumes:
     - ./volumes/html:/var/www/html
   restart: always
   environment:
     WORDPRESS_DB_HOST: db
     WORDPRESS_DB_USER: root
     WORDPRESS_DB_PASSWORD: password
     WORDPRESS_DB_NAME: wordpress
 nginx:
   depends_on:
     - wordpress
   image: nginx
   volumes:
     - ./volumes/nginx/html:/usr/share/nginx/html
     - ./volumes/nginx/conf.d:/etc/nginx/conf.d
   links:
     - wordpress
   ports:
     - "80:80"
     - "443:443"
   restart: always

nginx预配置

腾讯云有免费一年的SSL证书，申请成功后将压缩包上传到服务器中，并配置已好nginx（腾讯云文档-nginx配置ssl）

1. volumes目录下创建nginx配置目录及文件、同时创建存放SSL的目录

   mkdir nginx && cd nginx && mkdir conf.d html && cd conf.d && mkdir certs && touch default.conf
   

2. 证书文件上传并解压到刚刚创建的certs目录中

3. 配置default.conf,以下为参照：

server {
  listen       80;
  listen  [::]:80;
  server_name  domain.exapmle.com;
  client_max_body_size 1024M;
  sendfile on;
  location / {
    return 301 https://$host$request_uri;
  }
}
server {
  listen 443 ssl;
  server_tokens off;
  keepalive_timeout 5;
  root /usr/share/nginx/html;
  index index.html;
  server_name domain.exapmle.com;
  ssl_certificate /etc/nginx/conf.d/certs/证书名称.crt;
  ssl_certificate_key /etc/nginx/conf.d/certs/证书名称.key;
  ssl_session_timeout 5m;
  ssl_protocols TLSv1.2 TLSv1.3;
  ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:HIGH:!aNULL:!MD5:!RC4:!DHE;
  ssl_prefer_server_ciphers on;
  client_max_body_size 1024M;
  sendfile on;
  location / {
    proxy_pass http://wordpress;
    proxy_http_version    1.1;
    proxy_cache_bypass    $http_upgrade;
    proxy_set_header Upgrade             $http_upgrade;
    proxy_set_header Connection          "upgrade";
    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_set_header X-Forwarded-Host    $host;
    proxy_set_header X-Forwarded-Port    $server_port;
  }
}

启动容器

docker-compose up -d

运行以上命令后完成服务器端的配置，首先运行 docker ps -a 验证 mysql、phpmyadmin、wordpress、nginx容器是否均成功启动。若均处于up状态，再通过访问站点开始配置wordpress！
