docker版wordpress的搭建

发表于 更新于
使用docker容器技术快速搭建wordpress站点，适合有一定程序经验的人操作，使用docker技术方便后续快速迁移。

这些步骤操作起来简单，但是走错了路就是坑，留个笔记，后续可以查询。

docker安装

本人用的centos环境，首先要更新docker，不要用系统自带的，可能版本是旧的，有些命令运行不了。

安装docker参考链接：https://docs.docker.com/engine/install/centos/

sudo yum remove docker
sudo yum install -y yum-utils
sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
sudo sed -i 's+download.docker.com+mirrors.tuna.tsinghua.edu.cn/docker-ce+' /etc/yum.repos.d/docker-ce.repo
sudo yum install docker-ce docker-ce-cli containerd.io
sudo systemctl start docker # 这个不要忘了
sudo docker run hello-world # 这个只是测试一下而已

也可以安装一下docker-compose：https://docs.docker.com/compose/install

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

unbuntu版本安装docker

vim docker-compose.yml
####### 例子 #######
services:
  db:
    image: mysql:8.0.27
    command: '--default-authentication-plugin=mysql_native_password'
    volumes:
      - ./db_data:/var/lib/mysql
    restart: always
    environment:
      - MYSQL_ROOT_PASSWORD=wp
      - MYSQL_DATABASE=wordpress
      - MYSQL_USER=wordpress
      - MYSQL_PASSWORD=wp

  wordpress:
    image: wordpress:latest
    volumes:
      - ./wp_data:/var/www/html
    ports:
      - "2233:80"
    restart: always
    environment:
      - WORDPRESS_DB_HOST=db
      - WORDPRESS_DB_USER=wordpress
      - WORDPRESS_DB_PASSWORD=wp
      - WORDPRESS_DB_NAME=wordpress

volumes: {}

配置完成并启动wordpress就可以在浏览器访问wordpress了。

关于docker pull下载慢的问题。

# 更改系统的docker配置
vim /etc/docker/daemon.json
# 添加
{
  "registry-mirrors": [
      "https://registry.docker-cn.com",
      "https://docker.mirrors.ustc.edu.cn"
  ]
}
service docker restart

wordpress配置

找到/var/www/html/wp-content/themes目录替换主题，找到宿主机目录/var/lib/docker/volumes/wordpress_wordpress/_data/替换就行。

容器时区不对的解决方法：docker cp /usr/share/zoneinfo/Asia/Shanghai c177fc4749c0:/etc/localtime
