docker下载安装

系统环境：centos7.9

docker版本：docker-25.0.5

 

1、下载源码包，解压。

# cd /opt/ && wget https://download.docker.com/linux/static/stable/x86_64/docker-25.0.5.tgz
# ls /opt/docker-25.0.5.tgz
# tar xf /opt/docker-25.0.5.tgz
# ls /opt/docker
containerd containerd-shim-runc-v2 ctr docker dockerd docker-init docker-proxy runc

# cp /opt/docker/* /usr/bin/

2、添加启动文件
# vim /etc/systemd/system/docker.service

3、添加路由转发

# vim /etc/sysctl.conf
net.ipv4.ip_forward=1  #将接收到的IP数据包转发到其他主机或网络

# sysctl -p /etc/sysctl.conf

 

4、启动服务，验证
# systemctl daemon-reload
# systemctl start docker
# systemctl status docker
# systemctl enable docker.service
# docker -v
