Start shadowsocks server now:

sudo ss-server -s 10.140.0.4 -p 4444 -k password -m aes-256-cfb
 
change password to any you like 
10.140.0.4 is your internal ip, you can get it via ifconfig 

ifconfig 
ens4      Link encap:Ethernet  HWaddr 42:01:0a:8c:00:04  
          inet addr:10.140.0.4  Bcast:10.140.0.4  Mask:255.255.255.255
 
by the way, please remember set a new firewall rule for 4444 port.
or you can set a rule like, tcp:0-65535,  udp:0-65535

 

Install bbr to accelerate tcp 

wget –no-check-certificate https://github.com/teddysun/across/raw/master/bbr.sh  
chmod a+x bbr.sh 
sudo ./bbr.sh
sysctl net.ipv4.tcp_available_congestion_control
