wget --no-check-certificate https://raw.githubusercontent.com/teddysun/shadowsocks_install/master/shadowsocks.sh
chmod +x shadowsocks.sh
./shadowsocks.sh 2>&1 | tee shadowsocks.log

中间会提示输入SS SERVER使用的端口和连接密码。不输入则是系统默认.

安装完成后，脚本提示如下(记得记录下来)：
Congratulations, shadowsocks install completed!
Your Server IP:your_server_ip
Your Server Port:your_server_port
Your Password:your_password
Your Local IP:127.0.0.1
Your Local Port:1080
Your Encryption Method:aes-256-cfb

看到以上提示后就表明VPS上SS已经安装成功，并且已经设置了开机启动，VPS重启后不用手工启动SS。
到此就安装成功可以科学上网了
