Shadowsocks Hub (v0.3.0)

It is a web app for managing shadowsocks users, servers, nodes (a.k.a. exit points), products, accounts, and traffic. It is best suitable for companies, organizations, and groups of friends to manage their internal shadowsocks infrastructures.

Installation (Docker)

Install Docker.
Install Docker Compose.

Download Shadowsocks Hub:

cd ~
git clone https://github.com/shadowsocks/shadowsocks-hub.git

Create an environment file .env:
```
cd ~/shadowsocks-hub
touch .env
```
Add the following configuration to .env:
```
CODE_SECRET=changeThisSecret
MYSQL_PASSWORD=changeThisPassword
```
Change the value of CODE_SECRET with a long and random string.
Change the value of MYSQL_PASSWORD with another long and random string.
Create a directory for digital certificate:
```
cd ~/shadowsocks-hub
mkdir ssl
```
Set up digital certificate

Shadowsocks Hub uses https for all web traffic. It requires you to set up a digital certificate. You may obtain your digital certificate and key pair from any Certificate Authority (e.g. Let's Encrypt). Then rename the certificate file to server.cert and the key file to server.key. Finally, copy both server.cert and server.key to ~/shadowsocks-hub/ssl directory.
Create and start Docker container:
```
cd ~/shadowsocks-hub
docker-compose up -d
```
The first time will take a while (a few seconds ~ few minutes), in order to download docker images from Docker Hub and run them. So be patient. ;-)
Shadowsocks Hub uses shadowsocks-restful-api to manage shadowsocks node. Install it on every server acting as a shadowsocks node.

Non-Docker Installation (deprecated)

This installation method has been deprecated and will be removed in the future. Please use the above mentioned docker installation method.

Install Nodejs 8 or above.
Install MySQL.

Download and install Shadowsocks Hub:

cd ~
git clone https://github.com/shadowsocks/shadowsocks-hub.git
cd ~/shadowsocks-hub
npm i
sudo npm i -g knex
sudo npm i -g pm2

Create a MySQL database sshub:
```
CREATE DATABASE sshub;
```

Edit PM2 config file ~/shadowsocks-hub/ecosystem.config.js, change the following configurations to your local settings :

JWT_SECRET: '2wk0M@ow094B^&9k3==~o2soejd$sEEo@2(',
DATABASE_HOST: 'localhost',
DATABASE_PORT: '3306',
DATABASE_USER: 'root',
DATABASE_PASSWORD: 'd4f889df22769f54',

Change the value of `JWT_SECRET` with a long and random string.  
Change the values about the MySQL database connection to your local configurations.

Initialize database:

cd ~/shadowsocks-hub
knex migrate:latest --env production

Set up digital certificate

Shadowsocks Hub uses https for all web traffic. It requires you to set up a digital certificate. You may obtain your digital certificate and key pair from any Certificate Authority (e.g. Let's Encrypt). Then rename the certificate file as server.cert and the key file as server.key. Finally, copy both server.cert and server.key to ~/shadowsocks-hub.
Give non-root user permission to use port 80, 443

Shadowsocks Hub requires listenning to port 80 and 443. The following commands allow a non-root user to use both ports. This is the best practice from security point of view.
```
sudo apt-get install libcap2-bin
sudo setcap cap_net_bind_service=+ep /usr/bin/node
```
Shadowsocks Hub uses shadowsocks-restful-api to manage shadowsocks node. Install it on every server acting as a shadowsocks node.

Update from non-Docker installation to Docker installation

Make above mentioned docker version installation.

Backup existing database:

cd ~/shadowsocks-hub
mysqldump -u root -p sshub > backup.sql

Restore the backup to docker MySQL container:

cd ~/shadowsocks-hub
docker-compose up -d
cat backup.sql | docker exec -i shadowsocks-hub_db_1 mysql -u root --password=MYSQL_PASSWORD sshub

Note replace MYSQL_PASSWORD with your configration in .env file.

Run

Run Shadowsocks Hub:

cd ~/shadowsocks-hub
docker-compose up -d

Visiting Shadowsocks Hub:

Visiting your Shadowsocks Hub website using your server domain name in a web browser.
Change admin credential

For the sake of security, you should immeidately change the default admin user username and password upon installation. This can be done by login as the admin user and then update the username and password. The default username and password for the admin user are admin@email.com and pleaseChangePassword, respectively.
Run shadowsocks-restful-api on every server acting as a shadowsocks node.

Stop

cd ~/shadowsocks-hub
docker-compose stop

Restart

cd ~/shadowsocks-hub
docker-compose restart

Usage

Admin

Once logged in as the admin, the menu looks like:

The admin may choose to navigate to:

Managing servers. A server is a machine acting as a shadowsocks exit point. A server may have more than one node. Admin has to provide its IP address or domain name when adding a server. Admin may add, edit, and delete a server. Note that a server cannot be deleted if a node has been created using this server. Admin has to delete all its nodes before successfully deleting the server.

The admin may also check and navigate to any nodes, accounts, or users using a server, and check total traffic that a server has served.
Managing nodes. A node is a virtual shadowsocks exit point. The difference between server and node is that a server is an indpendent machine where a node is a logical machine whose functionality relies on server. There can be multiple nodes residing on a single server. From users' perspective, nodes using the same server are different shadowsocks exit points. Before adding a node, the underlying server has to be added into the system first. When adding a new node, the admin has to select a server, give it a descriptive name, and provide its managing port, and managing password. Admin may also edit and delete a node. Note that a node cannot be deleted if an account has been created using this node. Admin has to delete all its accounts before successfully deleting the node.

The admin may also check and navigate to the server that a node belongs to, any accounts or users using a node, and check total traffic that a node has serverd.
Managing products. A product is a shadowsocks service subscription. When adding a new product, the admin has to give it a descriptive name, select a period of subscription, and provide traffic allowance for the period. The admin may also edit and delete a product. Note that a product cannot be deleted if a request has been created on this product (regardless of whether the request is aproved or not).

The admin may also check and navigate to any accounts, users, or requests relating to a product.
Managing users. A user is a person using the shadowsocks service provided. The system is not open for registration, due to its nature of internal use. A new user has to be added by the admin into the system. When adding a new user, the admin has to provide an email and initial password. The admin may also edit and delete a user. Note that a user cannot be deleted if a request has been created for this this user (regardless of whether the request is aproved or not).

The admin may also check and navigate to any accounts, requests, products, nodes, or servers relating to a user.
Managing requests. A request is made by the admin for a user on a product, or is made by a user on a product. Before making a request, its underlying user and product have been added into the system. It requests for a shadowsocks service. The admin may choose to approve a request. Upon approval, the system will create one account on every node that the system has. These accounts will allow the user to use the specified shadowsocks service. The account information will be shown when the user login the system.

The admin may also check and navigate to any accounts, product, or user, and check total traffic relating to a request.
Managing accounts. An account is a shadowsocks account containing all information needed for its user to use the shadowsocks service. The admin may manually add a new account by selecting a user and a request. Before adding an account, its underlying user and request have to be added into the system first. The admin may also delete an account. Note that an account cannot be deleted if traffic information of the account has been created by the system.

The admin may also check and navigate to the server, node, product, user, request, and check total traffic relating to an account. In addition, the admin may choose to show a QR code encoding the account information.

Users

Once logged in as a user, the menu looks like:

A user may choose to navigate to:

Showing their accounts. A user check the latest traffic of any of their own accounts. They may also get the QR code displayed for any of their accounts.
Showing all products. A user may choose the make a request on a product. Once a request is created, it has to be approved by the admin before accounts created by the system.
Showing their requests. A user may check and navigate to any accounts, and check the traffic relating to a request.

Rate limit

You may enforce a rate limit by setting the maximum number of requests allowed within 15-minute window from the same ip address. Requests exceeding the limit will be refused with HTTP status code 429 Too Many Requests. This setting can be done by add the following config to the .env file. RATE_LIMIT = 50

Change the number to your choice.
