AWS EC2搭梯子记录(仅备忘, 非教程)

EC2 梯子

注册

需要绑定信用卡
https://aws.amazon.com/cn/

因为免费配额有限, 为防止超出配额被收费, 最好设定下配额超限的邮件提醒

创建一个 EC2 服务实例

建议 Ubuntu 节点选择韩国或者日本

安全组设置入站规则

需要开放 ssh/22, ss/xxx(梯子端口)

xshell 直接导入 pem 密钥

注意 Ubuntu 登录用户名是 ubuntu

装梯子

Add GPG public key:
wget -O- http://shadowsocks.org/debian/1D27208A.gpg | sudo apt-key add -
Add either of the following lines to your /etc/apt/sources.list:
# Ubuntu 14.04 or above
deb http://shadowsocks.org/ubuntu trusty main
# Debian Wheezy, Ubuntu 12.04 or any distribution with libssl > 1.0.1
deb http://shadowsocks.org/debian wheezy main
Then:
sudo apt-get update
sudo apt-get install shadowsocks-libev

梯子配置

sudo vi /etc/shadowsocks-libev/config.json

{
    "server":"0.0.0.0",
    "server_port":listen port,
    "password":"your passwd",
    "timeout":300,
    "method":"encrypt type",
    "fast_open": true
}

开梯子

# 启动
sudo service shadowsocks-libev start
# 停 
sudo service shadowsocks-libev stop

优化梯子

sudo vi /etc/sysctl.d/local.conf

net.ipv4.tcp_congestion_control = htcp
#net.ipv4.tcp_congestion_control = hybla
# turn on TCP Fast Open on both client and server side
net.ipv4.tcp_fastopen = 3

sudo /etc/init.d/procps restart

sudo vi /etc/modules

最下面添加一行

tcp_htcp

sudo modprobe tcp_htcp
