下载Docker并安装
#下载docker-20.10.0包 https://download.docker.com/linux/static/stable/x86_64/docker-20.10.0.tgz #上传到Centos系统/data/目录,如 scp docker-20.10.0.tgz [email protected]:/data/ #进入data目录,解压docker包 cd /data tar -zxvf docker-20.10.0.tgz #将解压出来的docker文件内容移动到 /usr/bin/ 目录下 cp docker/* /usr/bin/ #查看docker版本 docker version #查看docker信息 docker info
配置Docker开机自启动服务
#添加docker.service文件 vi /etc/systemd/system/docker.service #按i插入模式,复制如下内容:
[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 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
#添加文件可执行权限 chmod +x /etc/systemd/system/docker.service #重新加载配置文件 systemctl daemon-reload #启动Docker systemctl start docker #查看docker启动状态 systemctl status docker #查看启动容器 docker ps #设置开机自启动 systemctl enable docker.service #查看docker开机启动状态 enabled:开启, disabled:关闭 systemctl is-enabled docker.service
