1、移除以前docker相关包
sudo yum remove docker \
docker-client \
docker-client-latest \
docker-common \
docker-latest \
docker-latest-logrotate \
docker-logrotate \
docker-engine
2、配置yum源
sudo yum install -y yum-utils
sudo yum-config-manager \
--add-repo \
http://mirrors.aliyun.com/docker-ce/linux/centos/docker-ce.repo
3、安装小工具
yum install -y net-tools.x86_64 vim wget crul unzip
4、安装docker
yum install -y docker-ce docker-ce-cli containerd.io
#安装特定版本,安装配套k8s时用这个
yum install -y docker-ce-20.10.7 docker-ce-cli-20.10.7 containerd.io-1.4.6
5、启动docker并设置开机自启
systemctl enable docker --now
6、配置加速
sudo vim /etc/docker/daemon.json
6.1、设置镜像加速和日志分包
{
"registry-mirrors": [
"https://qiojqnqv.mirror.aliyuncs.com",
"https://hub-mirror.c.163.com",
"https://mirror.baidubce.com"
],
"log-driver": "json-file",
"log-opts": {
"max-size":"100m",
"max-file":"3"
}
}
6.2、重启docker服务
sudo systemctl daemon-reload
