安装

官方安装传送门

下载依赖

选择对应CentOS版本

下载stable版本的两个文件，这里是CentOS7.5

最新安装

• containerd.io-1.4.9-3.1.el7.x86_64.rpm
• docker-ce-20.10.8-3.el7.x86_64.rpm

旧版本安装

• containerd.io-1.2.5-3.1.el7.x86_64.rpm
• docker-ce-selinux-17.03.2.ce-1.el7.centos.noarch.rpm
• docker-ce-cli-18.09.4-3.el7.x86_64.rpm
• docker-ce-17.03.2.ce-1.el7.centos.x86_64.rpm

执行安装

$ yum install -y docker-ce-selinux-17.03.2.ce-1.el7.centos.noarch.rpm
$ yum install -y docker-ce-17.03.2.ce-1.el7.centos.x86_64.rpm

离线安装

环境：contos7.3(内核需为3.10+)

$ cat /etc/redhat-release
# CentOS Linux release 7.3.1611 (Core)

安装包传送门

这里下载的版本是：docker-19.03.9.tgz

1. 解压与安装

$ cd /usr/local/resource/docker
$ tar -xzvf docker-18.06.3-ce.tar
# 将二进制文件移动到bin下
$ mv  /usr/local/resource/docker/docker/*  /usr/bin/

2. 编写 docker.service

$ vim /etc/systemd/system/docker.service

3. 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. 重载service

$ systemctl daemon-reload

启动docker

设置开机启动

$ systemctl enable docker

启动

$ systemctl start docker

删除

删除安装包

$ yum remove docker-ce

删除镜像、容器、配置文件等

$ rm -rf /var/lib/docker
