title: Install the docker environment

|
> Because the `Tailchat` environment is a bit complicated for beginners, it provides a `docker-based one-command` environment configuration. But for students who are not familiar with `docker`, `docker` itself may also be a kind of complexity.
|
|
|
|
|
|
> Therefore, in order to facilitate everyone to quickly build `Tailchat`, this article is provided as a guide. Students who have a certain understanding of `docker` can skip this article
|
|
|
|
|
|
> This article takes `linux centos` as an example, the goal is to facilitate the deployment directly on the server. For students who want to use it on other systems (`windows`, `mac`), you can refer to the official documentation to install `docker`
|

|
## One-command installation of docker
|
|
|
|
|
|
Officially maintained one-command installation `Docker` script, suitable for students who don’t like to study details
|
|
|
|
|
|
Execute the following operations in sequence on the server terminal
|
|
|
|
|
|
```bash
|
|
|
curl -fsSL https://get.docker.com -o get-docker.sh
|
|
|
sudo sh get-docker.sh
|
|
|
```
|
|
|
|
|
|
If the installation is successful, you can skip the subsequent content.

## Manually install docker and docker compose
|
|
|
|
|
|
Official document: [https://docs.docker.com/engine/install/](https://docs.docker.com/engine/install/)
|
|
|
|
|
|
```bash
|
|
|
# If you have installed docker before, you can execute the following command to delete the old one
|
|
|
sudo yum remove docker \
|
|
|
docker-client \
|
|
|
docker-client-latest \
|
|
|
docker-common \
|
|
|
docker-latest \
|
|
|
docker-latest-logrotate \
|
|
|
docker-logrotate \
|
|
|
docker-engine
|
|
|
```
|
|
|
|
|
|
|
|
|
```bash
|
|
|
sudo yum install -y yum-utils # yum-utils provides the yum-config-manager command
|
|
|
|
|
|
sudo yum-config-manager \
|
|
|
--add-repo \
|
|
|
https://download.docker.com/linux/centos/docker-ce.repo
|
|
|
```
|
|
|
|
|
|
> Install docker and docker-compose plugins
|
|
|
|
|
|
```bash
|
|
|
sudo yum install -y docker-ce docker-ce-cli containerd.io docker-compose-plugin
|
|
|
```
|
|
|
|
|
|
*PS: `docker-compose-plugin` provides the `docker compose` command, the usage is the same as `docker-compose`*
|
|
|
|
|
|
> If `docker ps` shows that the daemon process is not started (Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?), you can execute the following command to start it: `sudo systemctl start docker`
|
|
|
|
|
|
## Install docker-compose separately
|
|
|
|
|
|
If the purchased server has been pre-installed with docker, if you want to install docker-compose separately, you can read this section:
|
|
|
|
|
|
Official document: [https://docs.docker.com/compose/install/](https://docs.docker.com/compose/install/)
|
|
|
|
|
|
```bash
|
|
|
curl -SL https://github.com/docker/compose/releases/download/v2.4.1/docker-compose-linux-x86_64 -o /usr/local/bin/docker-compose # Download binaries
|
|
|
sudo chmod +x /usr/local/bin/docker-compose # give execute permission
|
|
|
sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose # Soft link to path, can be called directly
|
|
|
docker-compose --version # The line command returns the version number and the installation is successful
|
|
|
```
|
|
|
|
|
|
## NOTICE
|
|
|
|
|
|
For historical reasons, `docker compose` has a `docker` plugin version and a `docker compose` standalone version. Generally speaking, `docker compose xxx` is equivalent to `docker-compose xxx`
