Linux环境安装Docker入门教程
安装
- 下载
wget https://download.docker.com/linux/static/stable/x86_64/docker-18.06.1-ce.tgz
- 解压
tar -xvf docker-18.06.1-ce.tgz
- 将解压出来的docker文件内容移动到 /usr/bin/ 目录下
cp docker/* /usr/bin/
- 将docker注册为service：vim /etc/systemd/system/docker.service
[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
启动
chmod +x /etc/systemd/system/docker.service #添加文件权限并启动docker
systemctl daemon-reload #重新加载配置文件
systemctl start docker #启动Docker
systemctl enable docker.service #设置开机自启
验证
systemctl status docker #查看Docker状态
docker -v #查看Docker版本
