离线安装 docker

一、下载二进制文件

a>从官网下载

https://download.docker.com/linux/static/stable/x86_64/

b>从我的网盘下载

[url=http://cdn.dimored.com/f/33339115-1421860553-b421e6?p=9840]docker-27.3.1.tgz[/url] (访问密码: 9840)

 

[root@hostname ~]# wget https://download.docker.com/linux/static/stable/x86_64/docker-27.3.1.tgz

2024-11-05 21:00:04 (93.9 MB/s) - ‘docker-27.3.1.tgz’ saved [75324256/75324256]

二、解压并复制文件

[root@hostname ~]# tar -xf docker-27.3.1.tgz 
[root@hostname ~]# mv docker/* /usr/bin/
[root@hostname ~]# rm -rf docker
[root@hostname ~]# rm -rf docker-27.3.1.tgz

 

三、配置docker数据目录

mkdir /etc/docker

cat > /etc/docker/daemon.json<< EOF
{
"log-driver":"json-file",
"log-opts": {"max-size":"500m", "max-file":"3"},
"insecure-registries": ["regharbor.demo.cn"],
"data-root": "/data/docker",
"bip": "172.30.35.1/24"
}
EOF

如下配置来源于网络仅供参考：

网络优化参数
{
    "log-driver": "json-file",
    "log-opts": {
        "max-size": "500m",
        "max-file": "3"
    },
    "insecure-registries": ["regharbor.gaiaworks.cn"],
    "data-root": "/data/docker",
    "bip": "172.30.35.1/24",
    
    // 网络相关优化
    "mtu": 1500,
    "default-address-pools": [
        {
            "base": "172.30.0.0/16",
            "size": 24
        }
    ],
    "icc": false,
    
    // DNS配置
    "dns": ["8.8.8.8", "8.8.4.4"],
    
    // 存储驱动优化
    "storage-driver": "overlay2",
    "storage-opts": ["overlay2.override_kernel_check=true"]
}

参数说明
网络安全：
icc: false - 禁用容器间通信，增加安全性
default-address-pools - 定义新建网络的IP地址池范围
mtu - 设置最大传输单元大小，优化网络性能

性能优化：
storage-driver: overlay2 - 使用性能更好的存储驱动
dns - 配置可靠的DNS服务器，提高域名解析速度

注意事项
修改配置后需要重启 Docker 服务才能生效
在修改 bip 和网络相关配置时，需要确保：
不与现有网络冲突
不与 VPN 网段冲突
预留足够的 IP 地址空间

生产环境建议启用日志轮转和大小限制，防止日志占用过多磁盘空间

 

四、制作systemctl 启动文件

cat >>/etc/systemd/system/docker.service<<EOF
[Unit]
Description=Docker Application Container Engine
Documentation=https://docs.docker.com
After=network-online.target firewalld.service
Wants=network-online.target

[Service]
Type=notify
ExecStart=
ExecStart=/usr/bin/dockerd
ExecReload=/bin/kill -s HUP $MAINPID
LimitNOFILE=infinity
LimitNPROC=infinity
LimitCORE=infinity
TimeoutStartSec=0
Delegate=yes
KillMode=process
Restart=on-failure
StartLimitBurst=3
StartLimitInterval=60s

[Install]
WantedBy=multi-user.target
EOF

 

[root@hostname ~]# systemctl start docker  #启动
[root@hostname ~]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES

 

[root@hostname ~]# systemctl enable docker  #配置开机启动
Created symlink /etc/systemd/system/multi-user.target.wants/docker.service → /etc/systemd/system/docker.service.
