docker compose+wordpress+nginx+mysql

第一步、安装docker 与docker compose 请参考https://u.sb/debian-install-docker/

第二步、创建docker-compose.yml

mkdir wordpress
vim docker-compose.yml

version: '3.1'
services:
  nginx:                                                            #nginx
    image: nginx                                                    #镜像来源
    container_name: nginx                                           #镜像名称                                 
    restart: always                                                 #永远重启                                           
    network_mode: "host"                                        #设置网络模式宿主机的IP和端口
    volumes:
      - /home/docker/nginx/nginx.conf:/etc/nginx/nginx.conf         #nginx的配置文件挂载
      - /home/docker/nginx/conf.d:/etc/nginx/conf.d                 #nginx的配置目录挂载
      - /home/docker/nginx/logs:/var/log/nginx                      #nginx的日志目录挂载
      - /home/docker/nginx/www:/www                                 #项目目录挂载
      - /etc/nginx/conf.d/cert/:/etc/nginx/conf.d/cert/             #ssl证书挂载
      - /etc/localtime:/etc/localtime:ro                            #时间同步挂载
  blog:                                                        #wordpress
    image: wordpress:latest
    container_name: blog
    restart: always
    ports:
      - 30080:80                                                #暴露端口信息(HOST:CONTAINER)
    environment:                                                #设置环境变量
      WORDPRESS_DB_HOST: mysql                                  #数据库的配置参数
      WORDPRESS_DB_USER: root
      WORDPRESS_DB_PASSWORD: root
      WORDPRESS_DB_NAME: blog
    volumes:                                                   #文件挂载
      - /home/docker/blog:/var/www/html
    depends_on:                                               #解决容器的依赖、启动先后的问题
     - mysql     
  mysql:                                                     #mysql
   image: mysql:8.0.26
   container_name: mysql
   restart: always
   ports:
     - 30001:3306
   environment:
     MYSQL_DATABASE: blog
     MYSQL_ROOT_PASSWORD: root  
   volumes:
     - /home/docker/mysql/data:/var/lib/mysql                 #数据挂载
     - /home/docker/mysql/init:/docker-entrypoint-initdb.d    #启动挂载

修改nginx配置文件

vim /home/docker/nginx/conf.d/default.conf
server {
    listen       443 ssl;
    listen  [::]:443 ssl;
    server_name 你的域名;
    ssl_certificate  /etc/nginx/conf.d/cert/你的ssl文件.pem;
    ssl_certificate_key /etc/nginx/conf.d/cert/你的ssl文件.key;
    access_log  /var/log/nginx/blog.access.log  main;
    error_log  /var/log/nginx/blog.error.log notice;
 
    location ~* /xmlrpc.php {
      deny all;
    }
 
    location / {
      add_header 'Access-Control-Allow-Origin' '*';
      add_header 'Access-Control-Allow-Credentials' 'true';
      add_header 'Access-Control-Allow-Methods' 'GET, POST, OPTIONS';
      add_header 'Access-Control-Allow-Headers' 'DNT,X-CustomHeader,Keep-Alive,User-Agent,X-Requested-With,If-Modified-Since,Cache-Control,Content-Type';
      add_header Content-Security-Policy upgrade-insecure-requests;
      proxy_set_header X-Real-IP \$remote_addr;
      proxy_set_header Host \$host;
      proxy_set_header X-Forwarded-For \$proxy_add_x_forwarded_for;
      proxy_pass http://localhost:30080/;
    }
}
server {
    listen 80;
    server_name fanglina.cn www.fanglina.cn;
    rewrite ^(.*)$ https://\$host:443\$1 permanent;
}

第三步、启动容器

<code>docker compose up -d

第四步、如果报数据库错误：

docker restart mysql
docker restart blog

如果修改了docker-compose.yml，先docker compose down 之后再 docker compose up -d
