How to build a blog with Docker and wordpress (steps with pictures and text)

The following column WordPresstutorial will introduce to you how to use Docker and wordpress to build a personal blog. I hope it will be helpful to friends in need!

Use Docker and wordpress to build a personal blog

1. Come first Explain two concepts

Docker is an open source application container engine that allows developers to package their applications and dependency packages into a portable image, and then publish it to any popular Linux or Windows machine , virtualization can also be achieved. Containers completely use the sandbox mechanism and will not have any interfaces with each other

Docker-Compose is an orchestration service of Docker. It is a tool for defining and running complex applications on Docker, which allows Users deploy distributed applications in clusters.

• Service (service): An application container can actually include several container instances running the same image.
• Project (project): A complete business unit consisting of a set of associated application containers, defined in the docker-compose.yml file.

Compose's default management object is the project, and subcommands are used to conveniently manage the life cycle of a group of containers in the project.

2. Install Docker

The specific installation method can be installed according to your own system.

For window system installation, please refer to the novice tutorial: https://www.runoob.com/docker/windows-docker-install.html

MacOC installation:

Use Homebrew to install

macOS We can use Homebrew to install Docker.

Homebrew Cask already supports Docker for Mac, so you can easily use Homebrew Cask for installation.

The command is:

$ brew cask install docke

The specific screenshot of the installation is as follows:

After loading the Docker app, click Next, you may be asked You can enter the macOS login password. Afterwards, a prompt window for Docker running will pop up, and there is also a small whale icon on the status bar

After starting the terminal, you can check the installed Docker version through the command.

$ docker --version
Docker version 19.03.12, build 48a66213fe

3. Image acceleration

In view of domestic network problems, subsequent pulling of Docker images is very slow. We may need to configure an accelerator to solve the problem. I use NetEase’s image address: http://hub-mirror.c.163.com.

Click the Docker for mac application icon on the taskbar -> Perferences… -> Docker Engine. Just fill in the accelerator address in the list. After the modification is completed, click the Apply & Restart button, and Docker will restart and apply the configured image address.

Then enter in the terminal:

$ docker info

4. Install WordPress

Create a new folder , you can name it as you wish.

Then create the docker-compose.yml file and put it in the folder just now.

The content of docker-compose.yml is as follows:

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: wordpressvolumes:
    db_data: {}

Then enter the newly created folder directory in the terminal and use one line of commands to set up the blog:

$ docker-compose up -d

Problems may occur here, as shown below:

The reason for this problem is that image acceleration is not configured, because docker uses foreign images by default. Download The resource is relatively slow, so it needs to be modified to a domestic image for acceleration. For specific methods, please see the previous point 3, image acceleration.

The screenshot of the successful effect is as follows:

5. Front-end management page

Front-end access address: IP:8000/: Because I have just set up a blog, the IP is localhost

. Enter this page. You can choose the specific language according to your preference. Here I chose Chinese, click to continue.

You can fill in this information according to your personal preference.

After logging in to your account and password, the blog backend page is as follows:

Modify language:

Modify Theme:

Now your personal blog is complete!
