## 0. <a name='TableofContents'></a>OpenIM Config File

Ensuring that OpenIM operates smoothly requires clear direction on the configuration file's location. Here's a detailed step-by-step guide on how to provide this essential path to OpenIM:

1. **Using the Command-line Argument**:

   + **For Configuration Path**: When initializing OpenIM, you can specify the path to the configuration file directly using the `-c` or `--config_folder_path` option.

     ```bash
     ❯ _output/bin/platforms/linux/amd64/openim-api --config_folder_path="/your/config/folder/path"
     ```

   + **For Port Specification**: Similarly, if you wish to designate a particular port, utilize the `-p` option followed by the desired port number.

     ```bash
     ❯ _output/bin/platforms/linux/amd64/openim-api -p 1234
     ```

     Note: If the port is not specified here, OpenIM will fetch it from the configuration file. Setting the port via environment variables isn't supported. We recommend consolidating settings in the configuration file for a more consistent and streamlined setup.

2. **Leveraging the Environment Variable**:

   You have the flexibility to determine OpenIM's configuration path by setting an `OPENIMCONFIG` environment variable. This method provides a seamless way to instruct OpenIM without command-line parameters every time.

   ```bash
   export OPENIMCONFIG="/path/to/your/config"
   ```

3. **Relying on the Default Path**:

   In scenarios where neither command-line arguments nor environment variables are provided, OpenIM will intuitively revert to the `config/` directory to locate its configuration.



##  1. <a name='OpenIMDeploymentGuide'></a>OpenIM Deployment Guide

Welcome to the OpenIM Deployment Guide! OpenIM offers a versatile and robust instant messaging server, and deploying it can be achieved through various methods. This guide will walk you through the primary deployment strategies, ensuring you can set up OpenIM in a way that best suits your needs.

###  1.1. <a name='DeploymentStrategies'></a>Deployment Strategies

OpenIM provides multiple deployment methods, each tailored to different use cases and technical preferences:

1. **[Source Code Deployment Guide](https://doc.rentsoft.cn/guides/gettingStarted/imSourceCodeDeployment)**
2. **[Docker Deployment Guide](https://doc.rentsoft.cn/guides/gettingStarted/dockerCompose)**
3. **[Kubernetes Deployment Guide](https://github.com/openimsdk/open-im-server/tree/main/deployments)**

While the first two methods will be our main focus, it's worth noting that the third method, Kubernetes deployment, is also viable and can be rendered via the `environment.sh` script variables.

###  1.2. <a name='SourceCodeDeployment'></a>Source Code Deployment

In the source code deployment method, the configuration generation process involves executing `make init`, which fundamentally runs the script `./scripts/init-config.sh`. This script utilizes variables defined in the [`environment.sh`](https://github.com/openimsdk/open-im-server/blob/main/scripts/install/environment.sh) script to render the [`config.yaml`](https://github.com/openimsdk/open-im-server/blob/main/deployments/templates/config.yaml) template file, subsequently generating the [`config.yaml`](https://github.com/openimsdk/open-im-server/blob/main/config/config.yaml) configuration file.

###  1.3. <a name='DockerComposeDeployment'></a>Docker Compose Deployment

Docker deployment offers a slightly more intricate template. Within the [openim-server](https://github.com/openimsdk/openim-docker/tree/main/openim-server) directory, multiple subdirectories correspond to various versions, each aligning with `openim-chat` as illustrated below:

| openim-server                                                | openim-chat                                                  |
| ------------------------------------------------------------ | ------------------------------------------------------------ |
| [main](https://github.com/openimsdk/openim-docker/tree/main/openim-server/main) | [main](https://github.com/openimsdk/openim-docker/tree/main/openim-chat/main) |
| [release-v3.2](https://github.com/openimsdk/openim-docker/tree/main/openim-server/release-v3.3) | [release-v3.2](https://github.com/openimsdk/openim-docker/tree/main/openim-chat/release-v1.3) |
| [release-v3.2](https://github.com/openimsdk/openim-docker/tree/main/openim-server/release-v3.2) | [release-v3.2](https://github.com/openimsdk/openim-docker/tree/main/openim-chat/release-v1.2) |

Configuration file modifications can be made by specifying corresponding environment variables, for instance:

```bash
export CHAT_IMAGE_VERSION="main"
export SERVER_IMAGE_VERSION="main"
```

These variables are stored within the [`environment.sh`](https://github.com/OpenIMSDK/open-im-server/blob/main/scripts/install/environment.sh) configuration:

```bash
readonly CHAT_IMAGE_VERSION=${CHAT_IMAGE_VERSION:-'main'}
readonly SERVER_IMAGE_VERSION=${SERVER_IMAGE_VERSION:-'main'}
```
> [!IMPORTANT]
> Can learn to read our mirror version strategy: https://github.com/openimsdk/open-im-server/blob/main/docs/contrib/images.md


Setting a variable, e.g., `export CHAT_IMAGE_VERSION="release-v1.3"`, will prioritize `CHAT_IMAGE_VERSION="release-v1.3"` as the variable value. Ultimately, the chosen image version is determined, and rendering is achieved through `make init` (or `./scripts/init-config.sh`).

> Note: Direct modifications to the `config.yaml` file are also permissible without utilizing `make init`.

###  1.4. <a name='EnvironmentVariableConfiguration'></a>Environment Variable Configuration

For convenience, configuration through modifying environment variables is recommended:

####  1.4.1. <a name='Recommendedusingenvironmentvariables'></a>Recommended using environment variables

+ PASSWORD

  + **Description**: Password for mongodb, redis, and minio.
  + **Default**: `openIM123`
  + Notes:
    + Minimum password length: 8 characters.
    + Special characters are not allowed.

  ```bash
  export PASSWORD="openIM123"
  ```

+ OPENIM_USER

  + **Description**: Username for redis, and minio.
  + **Default**: `root`

  ```bash
  export OPENIM_USER="root"
  ```

> mongo is `openIM`, use `export MONGO_OPENIM_USERNAME="openIM"` to modify

+ OPENIM_IP

  + **Description**: API address.
  + **Note**: If the server has an external IP, it will be automatically obtained. For internal networks, set this variable to the IP serving internally.

  ```bash
  export OPENIM_IP="ip"
  ```

+ DATA_DIR

  + **Description**: Data mount directory for components.
  + **Default**: `/data/openim`

  ```bash
  export DATA_DIR="/data/openim"
  ```

####  1.4.2. <a name='AdditionalConfiguration'></a>Additional Configuration

##### MinIO Access and Secret Key

To secure your MinIO server, you should set up an access key and secret key. These credentials are used to authenticate requests to your MinIO server.

```bash
export MINIO_ACCESS_KEY="YourAccessKey"
export MINIO_SECRET_KEY="YourSecretKey"
```

##### MinIO Browser

MinIO comes with an embedded web-based object browser. You can control the availability of the MinIO browser by setting the `MINIO_BROWSER` environment variable.

```bash
export MINIO_BROWSER="on"
```

####  1.4.3. <a name='SecurityConsiderations'></a>Security Considerations

##### TLS/SSL Configuration

For secure communication, it's recommended to enable TLS/SSL for your MinIO server. You can do this by providing the path to the SSL certificate and key files.

```bash
export MINIO_CERTS_DIR="/path/to/certs/directory"
```

####  1.4.4. <a name='DataManagement'></a>Data Management

##### Data Retention Policy

You may want to set up a data retention policy to automatically delete objects after a specified period.

```bash
export MINIO_RETENTION_DAYS="30"
```

####  1.4.5. <a name='MonitoringandLogging'></a>Monitoring and Logging

##### [Audit Logging](https://github.com/openimsdk/open-im-server/blob/main/docs/contrib/environment.md#audit-logging)

Enable audit logging to keep track of access and changes to your data.

```bash
export MINIO_AUDIT="on"
```

####  1.4.6. <a name='Troubleshooting'></a>Troubleshooting

##### Debug Mode

In case of issues, you may enable debug mode to get more detailed logs to assist in troubleshooting.

```bash
export MINIO_DEBUG="on"
```

####  1.4.7. <a name='Conclusion'></a>Conclusion

With the environment variables configured as per your requirements, your MinIO server should be ready to securely store and manage your object data. Ensure to verify the setup and monitor the logs for any unusual activities or errors. Regularly update the MinIO server and review your configuration to adapt to any changes or improvements in the MinIO system.

####  1.4.8. <a name='AdditionalResources'></a>Additional Resources
