谷歌云现在屏蔽国内试用，准备好美国身份信息（可以用虚拟地址生成器），VISA卡，申请试用Google Cloud Platform。申请获取免费300刀和365天使用权限，到期后不会自动扣分。
防火墙开启白名单
https://console.cloud.google.com/networking/firewalls/list
【网络】 –> 【防火墙规则】 –> 【创建防火墙规则】
VPC获取静态公网IP
https://console.cloud.google.com/networking/addresses/list
【网络】–> 【外部 IP 地址】 –> 【保留静态 IP】
优先选择亚洲节点（台湾彰化asia-east1、日本东京asia-northeast1）
创建虚拟机
https://console.cloud.google.com/compute/instances
【计算引擎】–> 【创建实例】
配置选择最低配置，微型共享，0.6G内存，操作系统默认Ubuntu，网络选择刚刚创建的静态IP
虚拟机创建完毕
关闭SSH密钥
谷歌云为了保证服务器安全性，默认开启SS密钥访问，为了方便关闭SSH密钥，开启ROOT密码访问，使用客户端连接
vi /etc/ssh/sshd_config # Authentication: PermitRootLogin yes //默认为no，需要开启root用户访问改为yes # Change to no to disable tunnelled clear text passwords PasswordAuthentication yes //默认为no，改为yes开启密码登陆 passwd root /etc/init.d/ssh restart
内核开启BBR优化
更新系统和软件
apt update apt upgrade
确定内核版本高于4.9
root@mike01:~# uname -a Linux mike01 4.9.0-8-amd64 #1 SMP Debian 4.9.144-3.1 (2019-02-19) x86_64 GNU/Linux
检查BBR状态
sysctl net.ipv4.tcp_available_congestion_control net.ipv4.tcp_available_congestion_control = cubic reno sysctl net.ipv4.tcp_congestion_control net.ipv4.tcp_congestion_control = cubic sysctl net.core.default_qdisc net.core.default_qdisc = pfifo_fast lsmod | grep bbr
安装BBR
wget --no-check-certificate https://github.com/teddysun/across/raw/master/bbr.sh chmod +x bbr.sh ./bbr.sh
检查内核
root@mike01:~/tools# sysctl net.ipv4.tcp_available_congestion_control net.ipv4.tcp_available_congestion_control = bbr cubic reno root@mike01:~/tools# sysctl net.ipv4.tcp_congestion_control net.ipv4.tcp_congestion_control = bbr root@mike01:~/tools# sysctl net.core.default_qdisc net.core.default_qdisc = fq root@mike01:~/tools# lsmod | grep bbr tcp_bbr 20480 4
搭建Shadowsocks
wget --no-check-certificate -O shadowsocks.sh https://raw.githubusercontent.com/teddysun/shadowsocks_install/master/shadowsocks.sh chmod +x shadowsocks.sh ./shadowsocks.sh 2>&1 | tee shadowsocks.log
service shadowsocks stop service shadowsocks start service shadowsocks restart
