Để đơn giản hơn trong quá trình lab hoặc dựng nhanh các môi trường cần thiết, hôm nay mình chia sẻ script cài đặt docker, docker-compose trên môi trường các hệ điều hành Ubuntu và CentOS.
- Ubuntu Server 18.04 64 bit.
- CentOS 7 Server 64 bit.
Các bước thực hiện như sau:
Bước 1: Update & tải các gói cần thiết.
Đối với Centos
|
1 2 |
yum update -y && yum install -y wget |
Đối với Ubuntu
|
1 2 |
apt update -y && apt install -y wget |
Bước 2: Tạo script như sau
Tạo với tên là docer-install.sh

Bước 3: Chạy lệnh sau để cài đặt
Cấp quyền thực thi và chạy:
|
1 2 3 |
chmod +x docker-install.sh ./docker-install.sh |
Sau khi thực hiện xong các bạn kiểm tra status docker
|
1 2 3 |
systemctl status docker sudo docker run hello-world |
Chúc các bạn thành công.!
