Deployment

Docker Deployment

Deployment command: docker run --name one-api -d --restart always -p 3000:3000 -e TZ=Asia/Shanghai -v /home/ubuntu/data/one-api:/data justsong/one-api-en

Update command: docker run --rm -v /var/run/docker.sock:/var/run/docker.sock containrrr/watchtower -cR

The first 3000 in -p 3000:3000 is the port of the host, which can be modified as needed.

Data will be saved in the /home/ubuntu/data/one-api directory on the host. Ensure that the directory exists and has write permissions, or change it to a suitable directory.

Nginx reference configuration:

server{
   server_name openai.justsong.cn;  # Modify your domain name accordingly
   
   location / {
          client_max_body_size  64m;
          proxy_http_version 1.1;
          proxy_pass http://localhost:3000;  # Modify your port accordingly
          proxy_set_header Host $host;
          proxy_set_header X-Forwarded-For $remote_addr;
          proxy_cache_bypass $http_upgrade;
          proxy_set_header Accept-Encoding gzip;
   }
}

Next, configure HTTPS with Let's Encrypt certbot:

# Install certbot on Ubuntu:
sudo snap install --classic certbot
sudo ln -s /snap/bin/certbot /usr/bin/certbot
# Generate certificates & modify Nginx configuration
sudo certbot --nginx
# Follow the prompts
# Restart Nginx
sudo service nginx restart

The initial account username is root and password is 123456.

Manual Deployment

  1. Download the executable file from GitHub Releases or compile from source: 
    git clone https://github.com/songquanpeng/one-api.git

# Build the frontend
cd one-api/web
npm install
npm run build

# Build the backend
cd ..
go mod download
go build -ldflags "-s -w" -o one-api
  2. Run: 
    chmod u+x one-api
./one-api --port 3000 --log-dir ./logs
  3. Access http://localhost:3000/ and log in. The initial account username is root and password is 123456.

For more detailed deployment tutorials, please refer to this page.

Multi-machine Deployment

  1. Set the same SESSION_SECRET for all servers.
  2. Set SQL_DSN and use MySQL instead of SQLite. All servers should connect to the same database.
  3. Set the NODE_TYPE for all non-master nodes to slave.
  4. Set SYNC_FREQUENCY for servers to periodically sync configurations from the database.
  5. Non-master nodes can optionally set FRONTEND_BASE_URL to redirect page requests to the master server.
  6. Install Redis separately on non-master nodes, and configure REDIS_CONN_STRING so that the database can be accessed with zero latency when the cache has not expired.
  7. If the main server also has high latency accessing the database, Redis must be enabled and SYNC_FREQUENCY must be set to periodically sync configurations from the database.

Please refer to the environment variables section for details on using environment variables.

Deployment on Control Panels (e.g., Baota)

Refer to #175 for detailed instructions.

If you encounter a blank page after deployment, refer to #97 for possible solutions.

Deployment on Third-Party Platforms

Deploy on Sealos

Please refer to this tutorial.

Deployment on Zeabur

Zeabur's servers are located overseas, automatically solving network issues, and the free quota is sufficient for personal usage.

  1. First, fork the code.
  2. Go to Zeabur, log in, and enter the console.
  3. Create a new project. In Service -> Add Service, select Marketplace, and choose MySQL. Note down the connection parameters (username, password, address, and port).
  4. Copy the connection parameters and run create database `one-api` to create the database.
  5. Then, in Service -> Add Service, select Git (authorization is required for the first use) and choose your forked repository.
  6. Automatic deployment will start, but please cancel it for now. Go to the Variable tab, add a PORT with a value of 3000, and then add a SQL_DSN with a value of <username>:<password>@tcp(<addr>:<port>)/one-api. Save the changes. Please note that if SQL_DSN is not set, data will not be persisted, and the data will be lost after redeployment.
  7. Select Redeploy.
  8. In the Domains tab, select a suitable domain name prefix, such as "my-one-api". The final domain name will be "my-one-api.zeabur.app". You can also CNAME your own domain name.
  9. Wait for the deployment to complete, and click on the generated domain name to access One API.

Configuration

The system is ready to use out of the box.

You can configure it by setting environment variables or command line parameters.

After the system starts, log in as the root user to further configure the system.

Usage

Add your API Key on the Channels page, and then add an access token on the Tokens page.

You can then use your access token to access One API. The usage is consistent with the OpenAI API.

In places where the OpenAI API is used, remember to set the API Base to your One API deployment address, for example: https://openai.justsong.cn. The API Key should be the token generated in One API.

Note that the specific API Base format depends on the client you are using.

graph LR
    A(User)
    A --->|Request| B(One API)
    B -->|Relay Request| C(OpenAI)
    B -->|Relay Request| D(Azure)
    B -->|Relay Request| E(Other downstream channels)
Loading

To specify which channel to use for the current request, you can add the channel ID after the token, for example: Authorization: Bearer ONE_API_KEY-CHANNEL_ID. Note that the token needs to be created by an administrator to specify the channel ID.

If the channel ID is not provided, load balancing will be used to distribute the requests to multiple channels.

Environment Variables

  1. REDIS_CONN_STRING: When set, Redis will be used as the storage for request rate limiting instead of memory.
    • Example: REDIS_CONN_STRING=redis://default:redispw@localhost:49153
  2. SESSION_SECRET: When set, a fixed session key will be used to ensure that cookies of logged-in users are still valid after the system restarts.
    • Example: SESSION_SECRET=random_string
  3. SQL_DSN: When set, the specified database will be used instead of SQLite. Please use MySQL version 8.0.
    • Example: SQL_DSN=root:123456@tcp(localhost:3306)/oneapi
  4. FRONTEND_BASE_URL: When set, the specified frontend address will be used instead of the backend address.
    • Example: FRONTEND_BASE_URL=https://openai.justsong.cn
  5. SYNC_FREQUENCY: When set, the system will periodically sync configurations from the database, with the unit in seconds. If not set, no sync will happen.
    • Example: SYNC_FREQUENCY=60
  6. NODE_TYPE: When set, specifies the node type. Valid values are master and slave. If not set, it defaults to master.
    • Example: NODE_TYPE=slave
  7. CHANNEL_UPDATE_FREQUENCY: When set, it periodically updates the channel balances, with the unit in minutes. If not set, no update will happen.
    • Example: CHANNEL_UPDATE_FREQUENCY=1440
  8. CHANNEL_TEST_FREQUENCY: When set, it periodically tests the channels, with the unit in minutes. If not set, no test will happen.
    • Example: CHANNEL_TEST_FREQUENCY=1440
  9. POLLING_INTERVAL: The time interval (in seconds) between requests when updating channel balances and testing channel availability. Default is no interval.
    • Example: POLLING_INTERVAL=5

Command Line Parameters

  1. --port <port_number>: Specifies the port number on which the server listens. Defaults to 3000.
    • Example: --port 3000
  2. --log-dir <log_dir>: Specifies the log directory. If not set, the logs will not be saved.
    • Example: --log-dir ./logs
  3. --version: Prints the system version number and exits.
  4. --help: Displays the command usage help and parameter descriptions.

FAQ

  1. What is quota? How is it calculated? Does One API have quota calculation issues?
    • Quota = Group multiplier * Model multiplier * (number of prompt tokens + number of completion tokens * completion multiplier)
    • The completion multiplier is fixed at 1.33 for GPT3.5 and 2 for GPT4, consistent with the official definition.
    • If it is not a stream mode, the official API will return the total number of tokens consumed. However, please note that the consumption multipliers for prompts and completions are different.
  2. Why does it prompt "insufficient quota" even though my account balance is sufficient?
    • Please check if your token quota is sufficient. It is separate from the account balance.
    • The token quota is used to set the maximum usage and can be freely set by the user.
  3. It says "No available channels" when trying to use a channel. What should I do?
    • Please check the user and channel group settings.
    • Also check the channel model settings.
  4. Channel testing reports an error: "invalid character '<' looking for beginning of value"
    • This error occurs when the returned value is not valid JSON but an HTML page.
    • Most likely, the IP of your deployment site or the node of the proxy has been blocked by CloudFlare.
  5. ChatGPT Next Web reports an error: "Failed to fetch"
    • Do not set BASE_URL during deployment.
    • Double-check that your interface address and API Key are correct.
