1、下载docker镜像包
wget https://download.docker.com/linux/static/stable/x86_64/docker-24.0.7.tgz
2、解压
tar -xvf docker-24.0.7.tgz
3、解压的docker文件夹全部移动至/usr/bin目录
cd docker
cp -p docker/* /usr/bin
4、注册服务
vi /usr/lib/systemd/system/docker.service
添加 下面内容
[Unit]
Description=Docker Application Container Engine
Documentation=http://docs.docker.com
After=network.target docker.socket
[Service]
Type=notify
EnvironmentFile=-/run/flannel/docker
WorkingDirectory=/usr/local/bin
ExecStart=/usr/bin/dockerd \
-H tcp://0.0.0.0:4243 \
-H unix:///var/run/docker.sock \
--selinux-enabled=false \
--log-opt max-size=1g
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=on-failure
[Install]
WantedBy=multi-user.target
5、重启守护进程
systemctl daemon-reload
systemctl start docker
systemctl enable docker
6、检查docker服务是否正常
systemctl status docker
