Super simple implementation of Docker to build a personal blog system

Install Docker

Update the yum package to the latest version: sudo yum update
Install the required packages: sudo yum install -y yum-utils device-mapper-persistent-data lvm2
Set the yum source to Alibaba Cloud, otherwise it will be very slow: sudo yum-config-manager --add-repo http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
sudo yum install docker-ce
Check the docker version after installation: docker -v
Set up a domestic mirror, ustc is a veteran Linux mirror service provider: vi /etc/docker/daemon.json
Enter the following content in the file:

{
"registry-mirrors": ["https://docker.mirrors.ustc.edu.cn"]
}

Start Docker: systemctl start docker
Check the docker status: systemctl status docker
Start at boot: systemctl enable docker

Install the image

The data of the blog system is recorded in the database, which means it depends on the database, so you need to install the database first: docker run --name db --env MYSQL_ROOT_PASSWORD=example -d mariadb
db is the name of the docker container, -d means starting it in daemon mode (running in the background), mariadb is a database of mysql, docker will first search for the mariadb image locally, if it is not found, it will automatically download it from the warehouse

View the docker container status: docker ps -a

Install the wordpress blog system: docker run --name MyWordPress --link db:mysql -p 8080:80 -d wordpress
Use --link db:mysql parameter to establish a connection between WordPress and the database. Use -p 8080:80 parameter to map port 80 of the original service to port 8080 of the host machine.

View the docker container status: docker ps -a
