docker 部署wordpress

安装docker

# 安装所需依赖
sudo yum install -y yum-utils device-mapper-persistent-data lvm2

# 添加Docker仓库 
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

# 安装Docker CE
sudo yum install docker-ce docker-ce-cli containerd.io

# 启动Docker服务
sudo systemctl start docker

安装 docker-compose

sudo curl -L "https://github.com/docker/compose/releases/latest/download/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

sudo chmod +x /usr/local/bin/docker-compose

sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

docker-compose --version

配置docker-compose.yml

在当前目录下创建一个docker-compose.yml文件，对应./wordpress的路径：

• image 指定了使用 wordpress:latest 镜像

• ports 把容器的 80 端口映射到主机的 8000 端口

• restart 设置为 always,表示始终重新启动容器

• volumes（卷） 将主机中当前目录下的 ./wordpress 目录挂载到容器的 /home/wordpress/wordpress,用于持久化保存 WordPress 数据，果通过volumes挂载后,你在宿主机上修改了配置文件,容器内部也会自动同步改动,无需任何其他操作。

• environment 设置了 WordPress 连接外部数据库的配置,包括数据库地址、用户名和密码

services:
  wordpress:
    image: wordpress:latest
    ports:
      - "8000:80"
    restart: always
    // 服务器项目路径：
    volumes:
      - ./wordpress:/home/wordpress/wordpress
    environment:
      - WORDPRESS_DB_HOST=X.X.X.X:3306
      - WORDPRESS_DB_USER=数据库用户名
      - WORDPRESS_DB_PASSWORD=数据库密码

启动docker-compose脚本

docker-compose  up -d

配置nginx

映射到8000端口，对应上面的配置：proxy_pass http://127.0.0.1:8000;

重启nginx

server {
    listen       80;
    server_name bugu.25youpin.com;
    #return 301 https://h5test.25youpin.com$request_uri;
    rewrite ^(.*)$ https://$host$1 permanent;
}

server {
    listen 443;
    server_name bugu.25youpin.com;

    ssl on;
    ssl_certificate   cert/2116658__25youpin.com.pem;
    ssl_certificate_key  cert/2116658__25youpin.com.key;
    ssl_session_timeout 5m;
    ssl_ciphers ECDHE-RSA-AES128-GCM-SHA256:ECDHE:ECDH:AES:HIGH:!NULL:!aNULL:!MD5:!ADH:!RC4;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers on;

      location / {
                proxy_pass http://127.0.0.1:8000;
                proxy_redirect  off;
                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-Host $server_name;
                proxy_set_header X-Forwarded-Proto https;
                proxy_set_header Upgrade $http_upgrade;
                proxy_set_header Connection "upgrade";
                proxy_read_timeout 86400;
    }
    error_log  /var/log/nginx/bugutest.log;
}

更改wordpress 配置文件

根目录下的wp-config.php文件：
