1 setup
cd /usr/local/resource/docker
tar -xvf docker-19.03.4.tgz
mv docker/* /usr/bin/ # 将二进制文件移动到bin下
2 systemd docker.service
vim /etc/systemd/system/docker.service
3 然后将以下内容粘贴进去：
[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 -H tcp://0.0.0.0:2375 -H unix://var/run/docker.sock
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
4 授予执行权限：
chmod +x /etc/systemd/system/docker.service
5 重新加载：
systemctl daemon-reload
systemctl start docker
systemctl enable docker.service
6 测试是否成功：
systemctl status docker
docker -v
rpm方式安装
rpm -ivh containerd.io-1.2.2-3.el7.x86_64.rpm
rpm -ivh container-selinux-2.107-3.el7.noarch.rpm
rpm -ivh docker-ce-18.09.8-3.el7.x86_64.rpm
rpm -ivh docker-ce-cli-18.09.8-3.el7.x86_64.rpm
7 配置docker 的阿里云加速器
sudo mkdir -p /etc/docker
sudo tee /etc/docker/daemon.json <<-'EOF'
{
"registry-mirrors": ["https://aiyf7r3a.mirror.aliyuncs.com"]
}
EOF
sudo systemctl daemon-reload
sudo systemctl restart docker
# docker info | grep aliyuncs
