1、确认操作系统类型及内核版本
Docker依赖于Linux内核的一些特性,不同版本的Docker对内核版本有不同要求。例如,Docker 17.06及之后的版本通常需要Linux内核3.10及以上版本,Docker17.09及更高版本对应Linux内核4.9.x及更高版本。我们可以通过在终端执行uname -r命令来查看当前Linux系统的内核版本。
执行uname -r
后,输出为:
2、下载Docker安装包
我们需要提前在有网络的环境中下载好Docker的安装包。对于上述系统,对应的下载地址为:
https://download.docker.com/linux/static/stable/aarch64/
3、解压安装包
1、安装tar命令
对于Debian/Ubuntu系统:
sudo apt-get update
sudo apt-get install tar
对于CentOS系统:
sudo yum install tar
2、将下载的安装包解压,执行命令
tar -xvf docker-24.0.9.tgz
4、拷贝文件
解压后,将解压目录中的所有文件拷贝到/usr/bin
目录下,执行命令:
cp docker/* /usr/bin/
5、将Docker注册为service系统服务
1、创建Docker服务的配置文件:
vi /etc/systemd/system/docker.service
2、在打开的文件中,将下列配置添加进去并保存:
[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network - online.target firewalld.service
Wants=network - online.target
[Service]
Type=notify
# the default is not to use systemd for cgroups because the delegate issues still
# exists and systemd currently does not support the cgroup feature set required
# for containers run by docker
ExecStart=/usr/bin/dockerd --ipv6=false
ExecReload=/bin/kill -s HUP $MAINPID
# Having non - zero Limit*s causes performance problems due to accounting overhead
# in the kernel. We recommend using cgroups to do container - local accounting.
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity
# Uncomment TasksMax if your systemd version supports it.
# Only systemd 226 and above support this version.
#TasksMax=infinity
TimeoutStartSec=0
# set delegate yes so that systemd does not reset the cgroups of docker containers
Delegate=yes
# kill only the docker process, not all processes in the cgroup
KillMode=process
# restart the docker process if it exits prematurely
Restart=on - failure
StartLimitBurst=3
StartLimitInterval=60s
[Install]
WantedBy=multi - user.target
6、启动Docker
1、为Docker启动脚本赋予执行权限:
chmod +x /etc/systemd/system/docker.service
2、启动Docker服务
systemctl start docker
3、查看状态
systemctl status docker
4、配置开机Docker自启
systemctl enable docker.service
5、查看Docker的版本信息
docker -v
