BC-Linux8.6上面离线手动安装Docker引擎

目标

在BC-Linux上面手动安装Docker引擎。

步骤

查看防火墙状态

[root@localhost x86_64]# sudo systemctl status firewalld.service 
● firewalld.service - firewalld - dynamic firewall daemon

卸载已有docker

sudo dnf remove docker \
                  docker-client \
                  docker-client-latest \
                  docker-common \
                  docker-latest \
                  docker-latest-logrotate \
                  docker-logrotate \
                  docker-engine \
                  podman \
                  runc

检查服务器cpu架构

[root@localhost ~]# arch
x86_64

检查Linux发行版

[root@localhost ~]# cat /etc/*release

下载docker引擎安装包

https://download.docker.com/linux/rhel/在这个地址，选择适合的docker离线安装包。
再结合上面的信息，我们直接选择使用如下链接中的安装包：
https://download.docker.com/linux/rhel/8/x86_64/stable/Packages/
下载的离线包如下：

containerd.io-1.7.23-3.1.el8.x86_64.rpm
docker-buildx-plugin-0.17.1-1.el8.x86_64.rpm
docker-ce-27.3.1-1.el8.x86_64.rpm
docker-ce-cli-27.3.1-1.el8.x86_64.rpm
docker-ce-rootless-extras-27.3.1-1.el8.x86_64.rpm
docker-compose-plugin-2.29.7-1.el8.x86_64.rpm
然后上传上述文件。

安装离线docker包

sudo dnf install ./containerd.io-1.7.23-3.1.el8.x86_64.rpm ./docker-ce-27.3.1-1.el8.x86_64.rpm ./docker-ce-cli-27.3.1-1.el8.x86_64.rpm ./docker-buildx-plugin-0.17.1-1.el8.x86_64.rpm ./docker-compose-plugin-2.29.7-1.el8.x86_64.rpm ./docker-ce-rootless-extras-27.3.1-1.el8.x86_64.rpm

尝试启动

尝试启动docker和设置开机自启动，如下命令：

# 设置自启动
sudo systemctl enable --now docker
sudo systemctl enable containerd

测试

sudo docker run hello-world

Hello from Docker!
This message shows that your installation appears to be working correctly.

To generate this message, Docker took the following steps:
 1. The Docker client contacted the Docker daemon.
 2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    (amd64)
 3. The Docker daemon created a new container from that image which runs the
    executable that produces the output you are currently reading.
 4. The Docker daemon streamed that output to the Docker client, which sent it
    to your terminal.

To try something more ambitious, you can run an Ubuntu container with:
 $ docker run -it ubuntu bash

Share images, automate workflows, and more with a free Docker ID:
 https://hub.docker.com/

 https://docs.docker.com/get-started/

到这里没有报错，就说明docker安装成功。
本来，到这里docker的安装，就应该结束了的，但是，我们现在这个docker需要使用非root账号进行运行。接下来在进一步，设置一下非root用户运行docker配置。

配置非root用户运行Docker

# 新建docker用户，并添加到docker用户组
sudo useradd -m -s /bin/bash docker -g docker
# 重新激活用户组设置
newgrp docker
# 设置docker用户密码
sudo passwd docker
# 设置完密码后远程登录docker用户即可
ssh docker@192.168.1.10
# 登录成功后，再次测试docker运行情况：
[docker@localhost ~]$ docker run hello-world

到这里docker非root用户管理docker配置就设置完成了。由于给的机器磁盘有限，我们需要再进一步，设置docker滚动日志。

配置Docker滚动日志

# 新建文件
sudo vim /etc/docker/daemon.json

内容如下：

{
  "log-driver": "json-file",
  "log-opts": {
    "max-size": "700m",
    "max-file": "3"
  }
}

保持该文件后，重启docker：

sudo systemctl restart docker

到这里，手动安装docker就告一个段落了。
