甲骨文云，搭建Docker专用机

第一步 申请新实例

• 映像选 Canonical-Ubuntu
• 添加 SSH 密钥中 为我生成密钥对 保存私钥和公钥
• 添加 SSH 密钥中 上载公共密钥文件 (.pub)，选择刚刚保存的公钥文件
• 安全列表 清除全部规则

第二步 CF域名解析并配置iptables

• 域名解析，开启小云朵
• ssh登录服务器
• 更改iptables

#!/bin/bash
/usr/sbin/iptables -P INPUT ACCEPT
/usr/sbin/iptables -P FORWARD ACCEPT
/usr/sbin/iptables -P OUTPUT ACCEPT
/usr/sbin/iptables -F
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 173.245.48.0/20 -j ACCEPT
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 103.21.244.0/22 -j ACCEPT
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 103.22.200.0/22 -j ACCEPT
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 103.31.4.0/22 -j ACCEPT
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 141.101.64.0/18 -j ACCEPT
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 108.162.192.0/18 -j ACCEPT
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 190.93.240.0/20 -j ACCEPT
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 188.114.96.0/20 -j ACCEPT
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 197.234.240.0/22 -j ACCEPT
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 198.41.128.0/17 -j ACCEPT
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 162.158.0.0/15 -j ACCEPT
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 104.16.0.0/13 -j ACCEPT
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 104.24.0.0/14 -j ACCEPT
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 172.64.0.0/13 -j ACCEPT
/usr/sbin/iptables -I INPUT -p tcp -m multiport --dports 80,443 -s 131.0.72.0/22 -j ACCEPT
/usr/sbin/iptables -A INPUT -p tcp -m multiport --dports 80,443 -j DROP

• sudo nano /etc/systemd/system/rc-local.service

[Unit]
Description=/etc/rc.local Compatibility 
ConditionPathExists=/etc/rc.local 

[Service]
Type=forking 
ExecStart=/etc/rc.local start 
TimeoutSec=0 
StandardOutput=tty 
RemainAfterExit=yes 
SysVStartPriority=99 

• sudo nano /etc/rc.local
• sudo chmod +x /etc/rc.local
• sudo systemctl enable rc-local
• sudo systemctl start rc-local.service
• sudo systemctl status rc-local.service
• 重启服务器
• sudo iptables -L 查看是否生效

#!/bin/sh -e 
## rc.local
#start script
/home/ubuntu/c_iptables.sh
#end script
echo "added sucessfully!" > /tmp/added_script.log 
exit 0

第三步 安装docker

• sudo apt update
• sudo apt install apt-transport-https ca-certificates curl gnupg-agent software-properties-common
• curl -fsSL https://download.docker.com/linux/ubuntu/gpg sudo apt-key add -
• sudo add-apt-repository “deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable”
• sudo apt update
• sudo apt install docker-ce
• sudo systemctl status docker
• sudo curl -L “https://github.com/docker/compose/releases/download/v2.6.1/docker-compose-$(uname -s)-$(uname -m)” -o /usr/local/bin/docker-compose
• sudo chmod +x /usr/local/bin/docker-compose
• docker-compose –version

第四步 安装 Nginx Proxy Manager

• mkdir ngpm
• cd ngpm
• nano docker-compose.yml
• sudo docker-compose up -d

version: '3'
services:
  app:
    image: 'jc21/nginx-proxy-manager:latest'
    restart: unless-stopped
    ports:
      - '80:80'
      - '81:81'
      - '443:443'
    volumes:
      - ./data:/data
      - ./letsencrypt:/etc/letsencrypt

• 登录到 http://ip:81
• Email: admin@example.com
• Password: changeme
• 反代 Nginx Proxy Manager
