Docker – Docker로 WordPress Blog 만들기

설치한 Docker 환경에서 WordPress를 만들어 보자.

먼저 WordPress를 실행하려면 Apache (또는 NGINX) + PHP + MariaDB (mySQL)을 먼저 설치하고 WordPress를 설치 한뒤 설정을 하는 방법으로 WordPress를 구축 했었다.

DB는 계속 사용해야 하는 부분으로 MariaDB(mySQL)만 분리해서 준비되어 있다면 Docker 이미지를 이용하면 나머지 작업은 간단하게 할 수 있다. 당근 이 2개 모두 Docker를 이용하여 실행 하는 것이 가능 하다.

1. 프로젝트 디렉토리 만들기

$ mkdir my-wordpress
$ cd my-wordpress

2. docker-compose 만들기

docker-compose.yml 파일을 만들고 WordPress 와 mySQL 인스턴스 데이터를 현대 디렉토리를 사용하도록 구성 한다.

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
    volumes:
      - wordpress_data:/var/www/html
    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: {}
  wordpress_data: {}

3. container 구동 시키기

root@dck:~/my-wordpress# docker-compose up -d

Creating volume "my-wordpress_db_data" with default driver
Creating volume "my-wordpress_wordpress_data" with default driver

4. 실행된 컨테이너 확인

root@dck:~/my-wordpress# docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED              STATUS              PORTS                  NAMES

root@dck:~/my-wordpress#

5. WordPress 접속 및 설정하기

브라우저로 docker container를 설치한 vm에 접속하면 WordPress 설정 화면을 만날수 있다.
이제 부터는 이전에 WordPress 설정을 한것 처럼 진행을 하면 된다.
