1. Server

1.1. Buy a Cloud Host

1.2. Solution 1: Using Original Shadowsocks

Installing pip

# yum install python3-pip
or
# curl "https://bootstrap.pypa.io/get-pip.py" -o "get-pip.py"
# python get-pip.py

// update
# pip3 install --upgrade pip

Installing shadowsocks

# pip3 install shadowsocks
# vim /etc/shadowsocks.json

{
  "server": "server_ip",//server ip address
  "server_port": 8388,//server port
  "local_address":"127.0.0.1",//local address
  "local_port":1080,//local port
  "port_password":{ //multiple port
          "9001":"password9001",
          "9002":"password9002",
          "9003":"password9003",
     },
  "password": "password",//password
  "method": "aes-256-cfb",//encryption
  "timeout":600 //timeout
  }

explanation:

- "server": "123.123.123.123" :: server ip address
- "server_port": 8388 :: server port
- "local_address":"127.0.0.1" :: local ip address
- "local_port":1080, :: local port
- "port_password" :: port and password
- "password": "password" :: password                                                                                                         
- "method": "aes-256-cfb" :: encrypt method, more detail:[[http://ucdok.com/project/generate_password.html][password tool]]
- "timeout":600 :: over time

Configuring auto-start script

#vim /etc/systemd/system/shadowsocks.service

[Unit]
Description=Shadowsocks

[Service]
TimeoutStartSec=0
ExecStart=/usr/bin/ssserver -c /etc/shadowsocks.json

[Install]
WantedBy=multi-user.target

Start shadowsocks
#systemctl enable shadowsocks
#systemctl start shadowsocks
#systemctl status shadowsocks -l

Auto install script

$ vim install-shadowsocks.sh, content of file from

install-shadowsocks.sh

# chmod +x install-shadowsocks.sh
# ./install-shadowsocks.sh

1.3. Solution 2: Using docker

Installing docker

# CentOS Linux
# yum install docker
# systemctl enable docker
# systemctl start docker

# CentOS Stream
# Official Site from Docker: https://docs.docker.com/engine/install/centos/
# yum install -y yum-utils
# yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo
# yum install docker-ce docker-ce-cli containerd.io
# systemctl start docker
# systemctl enable docker

Deploy shadowsocks

# docker run -dt --name ss -p 6443:6443 mritd/shadowsocks -s "-s 0.0.0.0 -p 6443 -m aes-256-cfb -k test123 --fast-open"

2. Client

2.1. Linux

2.1.1. Command Line Client on Linux

Linux series
- Debian/Ubuntu:
```
$ sudo apt-get install python-pip
$ sudo pip install shadowsocks
```
- Fedora/Centos:
```
$ sudo yum install python-setuptools   or   sudo dnf install python-setuptools
$ sudo easy_install pip
$ sudo pip install shadowsocks
```
- OpenSUSE:
```
$ sudo zypper install python-pip
$ sudo pip install shadowsocks
```
- Archlinux:
```
$ sudo pacman -S python-pip
$ sudo pip install shadowsocks
```
sslocal is the client software and ssserver is the server software. On some Linux distros such as ubuntu, the shadowsocks client sslocal is installed under usr/local/bin. On Others such as Arch sslocal is installed under /usr/bin. Your can use whereis command to find the exact location.
```
$ whereis sslocal
```
sslocal: /usr/local/bin/sslocal

/etc/shadowsocks.json

{
"server":"server-ip",
"server_port":8000,
"local_address": "127.0.0.1",
"local_port":1080,
"password":"your-password",
"timeout":600,
"method":"aes-256-cfb"
}

// start
$ sudo sslocal -c /etc/shadowsocks.json

// To run in the background
$ sudo sslocal -c /etc/shadowsocks.json -d start

/etc/rc.local

$ sudo vim /etc/rc.local

sudo sslocal -c /etc/shadowsocks.json -d start

// Check if It Works
# sudo systemctl status rc-local.service

2.1.2. Global Proxy

Install and Configure polipo

$ sudo apt install polipo
$ sudo vim /etc/polipo/config

logSyslog = true
logFile = /var/log/polipo/polipo.log
proxyAddress = "0.0.0.0"
socksParentProxy = "127.0.0.1:1080"
socksProxyType = socks5
chunkHighMark = 50331648
objectHighMark = 16384
serverMaxSlots = 64
serverSlots = 16
serverSlots1 = 32

Restart polipo
```
$ sudo systemctl restart polipo
```

Export http_proxy and https_proxy

$ export http_proxy="http://127.0.0.1:8123/"
$ export https_proxy="https://127.0.0.1:8123/"

testing
```
$ curl www.google.com
```

2.1.3. Solving Problem

ShadowSocks start error: undefined symbol EVP_CIPHER_CTX_cleanup [Reason]

openssl 1.1.0 "EVP_CIPHER_CTX_cleanup" is old.

[Solving]

$ vim /usr/local/lib/python3.5/dist-packages/shadowsocks/crypto/openssl.py

VIM Command：
:%s/cleanup/reset/
:x

not support "chacha20" [Solving]

$ apt install m2crypto gcc -y
$ wget -N --no-check-certificate https://download.libsodium.org/libsodium/releases/libsodium-1.0.8.tar.gz
$ tar zxvf libsodium-1.0.8.tar.gz
$ cd libsodium-1.0.8
$ sudo ./configure
$ sudo make && make install
$ sudo echo "include ld.so.conf.d/*.conf" > /etc/ld.so.conf
$ sudo echo "/lib" >> /etc/ld.so.conf
$ sudo echo "/usr/lib64" >> /etc/ld.so.conf
$ sudo echo "/usr/local/lib" >> /etc/ld.so.conf
$ sudo ldconfig
