离线安装docker (Red Hat Enterprise Linux 9)

1、下载与解压

# 下载
wget -c https://download.docker.com/linux/static/stable/x86_64/docker-27.5.1.tgz

# 解压
tar -zxvf docker-docker-27.5.1.tgz

# 复制到/usr/bin
cp docker/* /usr/bin

2、添加到service

vim /etc/systemd/system/docker.service

这里是基础配置，详细配置可使用指定配置文件来启动服务

[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
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

3、启动服务

#添加文件权限并启动docker
chmod +x /etc/systemd/system/docker.service
#重载unit配置文件
systemctl daemon-reload
#启动docker
systemctl start docker       
#设置开机自启
systemctl enable docker.service

 

4、检查状态

# 状态
systemctl status docker
# 版本
docker -v
