一直用centos顺手了，这次使用的centos7，在linode上开启。
首先是在服务器上安装shadowsocks：
yum install epel-release
yum update
yum install Python-setuptools m2crypto supervisor
easy_install pip
pip install shadowsocks
然后vi /etc/shadowsocks.json：
{ "server":"xxxxx", "server_port":8387, "local_port":1080, "password":"xxxx", "timeout":600, "method":"aes-256-cfb" }
server的xxxx改为你的服务器IP
password的xxxx就设置成你的登录密码
创建脚本 /etc/init.d/shadowsocks
添加以下内容
#!/bin/sh
#
# shadowsocks start/restart/stop shadowsocks
#
# chkconfig: 2345 85 15
# description: start shadowsocks/ssserver at boot time
start(){
ssserver -c /etc/shadowsocks.json -d start
}
stop(){
ssserver -c /etc/shadowsocks.json -d stop
}
restart(){
ssserver -c /etc/shadowsocks.json -d restart
}
case “$1” in
start)
start
;;
stop)
stop
;;
restart)
restart
;;
*)
echo “Usage: $0 {start|restart|stop}”
exit 1
;;
esac
增加权限：
chmod +x /etc/init.d/shadowsocks
开机自启动：
chkconfig –add shadowsocks
使用秋水逸冰的一键脚本安装BBR加速：
#!/usr/bin/env bash
#
# Auto install latest kernel for TCP BBR
#
# System Required: CentOS 6+, Debian7+, Ubuntu12+

创建bbr.sh. 执行。
linode上面，还需要更新grub2：
grub2-mkconfig -o /boot/grub/grub.cfg
接着在Linode后台 – Dashboard – Edit，进行编辑，选择启动方式为GRUB 2。
可以使用下面的方法来检测BBR是否开启成功：
[root@linode1495332 ~]# sysctl net.ipv4.tcp_available_congestion_control net.ipv4.tcp_available_congestion_control = bbr cubic reno [root@linode1495332 ~]# lsmod | grep bbr tcp_bbr 16384 70
然后重启，shadowsocks应该就可以使用了
