WordPress创建

一个部署包含nginx tomcat mysql等，这种有多种部署，容器编排。

Docker compose
单机多容器部署
通过yml定义多容器部署
win/mac默认提供docker compose，linux需要安装

案例官网 https://docs.docker.com/compose/install/
get started with wordpress
安装compose

sudo curl -L "https://github.com/docker/compose/releases/download/1.28.5/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose
#授权
sudo chmod +x /usr/local/bin/docker-compose
#测试
docker-compose --version

WordPress创建

mkdir my_wordpress
cd my_wordpress

创建.yml ``` version: ‘3.3’

services: db: image: mysql:5.7 volumes:

   - db_data:/var/lib/mysql
 restart: always
 environment:
   MYSQL_ROOT_PASSWORD: somewordpress
   MYSQL_DATABASE: wordpress
   MYSQL_USER: wordpress
   MYSQL_PASSWORD: wordpress

wordpress: depends_on:

   - db
 image: wordpress:latest
 ports:
   - "8000:80"
 restart: always
 environment:
   WORDPRESS_DB_HOST: db:3306
   WORDPRESS_DB_USER: wordpress
   WORDPRESS_DB_PASSWORD: wordpress
   WORDPRESS_DB_NAME: wordpress

volumes: db_data: {} ``` 先构建mysql 然后拉去wordpress容器

构建 docker-compose up -d

实战
docker run —name 容器名 -e MYSQL_ROOT_PASSWORD=password -d mysql:tag
-e: 指定环境变量

MYSQL_ROOT_PASSWORD官方变量设置，还有很多，这个是设置密码
在/docker-entrypoint-init.db.d 下放入初始化脚本就完成脚本的初始化
