Now, let's start the job.
Step 1: in Xshell/Centos(root)
yum install -y wget 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
after you input the line 4 and enter, it will ask you to input your password and port for SS, just input it, after this it will give an list for you to choose which encryption method you need, here recommend the "aes-256-cfb".
