Before diving into the installation process, ensure that your system is updated. You’ll need Python and pip, Python’s package manager, for installing Shadowsocks. Open your terminal and run the following commands:

sudo apt update
sudo apt install python3-pip

Installing Shadowsocks

With pip ready, install Shadowsocks by executing:

sudo pip3 install https://github.com/shadowsocks/shadowsocks/archive/master.zip

This command fetches the latest version of Shadowsocks directly from its GitHub repository, ensuring that you have the most recent features and security patches.

Configuration: Tuning Shadowsocks for Optimal Performance

After installation, configuring Shadowsocks to meet your specific needs is essential. This involves creating a configuration file with your server details and preferred settings.

    "local_port":1080,
    "password":"your_password",
    "timeout":300,

Optional Steps: Enhancing Your Shadowsocks Experience

While Shadowsocks is now up and running, there are additional steps you can take to tailor the experience further.

System Proxy Configuration

For applications that do not natively support SOCKS proxies, configuring your system’s proxy settings can route your traffic through Shadowsocks. This can be accomplished by setting environment variables:

export http_proxy="socks5://127.0.0.1:1080"
export https_proxy="socks5://127.0.0.1:1080"

Using Polipo to Convert SOCKS to HTTP Proxy

Some applications only support HTTP proxies. In such cases, Polipo, a lightweight caching web proxy, can be installed to convert SOCKS proxy to HTTP:

sudo apt install polipo

Configure Polipo by editing its configuration file and restarting the service:

sudo nano /etc/polipo/config

Insert:

socksParentProxy = "localhost:1080"
socksProxyType = socks5

Restart Polipo:

sudo service polipo restart

Your HTTP proxy is now available at http://localhost:8123.
