## 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 [`openim.yaml`](https://github.com/openimsdk/open-im-server/blob/main/deployments/templates/openim.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 PASSWORD="openIM123" # Set password
export USER="root" # Set username
# Choose chat version and server version https://github.com/openimsdk/open-im-server/blob/main/docs/conversions/images.md, eg: main, release-v*.*
export CHAT_BRANCH="main"
export SERVER_BRANCH="main"
#... Other environment variables
# MONGO_USERNAME: This sets the MongoDB username
# MONGO_PASSWORD: Set the MongoDB password
# MONGO_DATABASE: Sets the MongoDB database name
# MINIO_ENDPOINT: set the MinIO service address
# API_URL: under network environment, set OpenIM Server API address
export API_URL="http://127.0.0.1:10002"
export CHAT_BRANCH="main"
export SERVER_BRANCH="main"
```
Next, update the configuration using `make init`:
These variables are stored within the [`environment.sh`](https://github.com/OpenIMSDK/openim-docker/blob/main/scripts/install/environment.sh) configuration:
```bash
make init
readonly CHAT_BRANCH=${CHAT_BRANCH:-'main'}
readonly SERVER_BRANCH=${SERVER_BRANCH:-'main'}
```
#### **2. Modify the automation script:**
Setting a variable, e.g., `export CHAT_BRANCH="release-v1.3"`, will prioritize `CHAT_BRANCH="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`).
```bash
scripts/install/environment.sh
```
> Note: Direct modifications to the `config.yaml` file are also permissible without utilizing `make init`.
Next, update the configuration using `make init`:
### 1.4. <a name='EnvironmentVariableConfiguration'></a>Environment Variable Configuration
```bash
make init
```
For convenience, configuration through modifying environment variables is recommended:
#### 3. Modify `config.yaml` and `.env` files (but will be overwritten when using `make init` again).
#### 1.4.1. <a name='1.Recommendedusingenvironmentvariables:https:github.comopenimsdkopen-im-serverblobmaindocscontribenvironment.md1-recommended-using-environment-variables'></a>[1. Recommended using environment variables:](https://github.com/openimsdk/open-im-server/blob/main/docs/contrib/environment.md#1-recommended-using-environment-variables)
The `config/config.yaml` file has detailed configuration instructions for the storage components.
+ PASSWORD
+ **Description**: Password for mysql, mongodb, redis, and minio.
+ **Default**: `openIM123`
+ Notes:
+ Minimum password length: 8 characters.
+ Special characters are not allowed.
The config file is available via [environment.sh](https://github.com/openimsdk/open-im-server/blob/main/scripts/install/environment.sh) configuration [openim.yaml](https://github.com/openimsdk/open-im-server/blob/main/deployments/templates/openim.yaml) template, and then through the `make init` to automatically generate a new configuration.
```bash
export PASSWORD="openIM123"
```
+ USER
## Environment variable
+ **Description**: Username for mysql, mongodb, redis, and minio.
+ **Default**: `root`
By setting the environment variable below, You can then refresh the configuration using `make init` or `./scripts/init-config.sh`
```bash
export USER="root"
```
##### MINIO
+ API_URL
+ [MINIO DOCS](https://min.io/docs/minio/kubernetes/upstream/index.html)
+ **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.
apiURL is the address of the api, the access address of the app, use s3 must be configured
```
export API_URL="http://ip:10002"
```
#### Overview
+ DATA_DIR
MinIO is an object storage server that is API compatible with Amazon S3. It's best suited for storing unstructured data such as photos, videos, log files, backups, and container/VM images. In this guide, we'll walk through the process of configuring MinIO with custom settings.
+ **Description**: Data mount directory for components.
+ **Default**: `/data/openim`
#### Default Configuration
```bash
export DATA_DIR="/data/openim"
```
Configuration can be achieved by modifying the default variables in the `./scripts/install/environment.sh` file. However, for more flexibility and dynamic adjustments, setting environment variables is recommended.

#### Setting Up the Environment Variables
##### [MinIO Access and Secret Key](https://github.com/openimsdk/open-im-server/blob/main/docs/contrib/environment.md#minio-access-and-secret-key)
##### IP Configuration
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.
By default, the system generates the public IP of the machine. To manually set a public or local IP address, use:
```bash
export MINIO_ACCESS_KEY="YourAccessKey"
export MINIO_SECRET_KEY="YourSecretKey"
```
##### [MinIO Browser](https://github.com/openimsdk/open-im-server/blob/main/docs/contrib/environment.md#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 IP=127.0.0.1
export MINIO_BROWSER="on"
```

This is the primary address MinIO uses for communications:
##### [Data Retention Policy](https://github.com/openimsdk/open-im-server/blob/main/docs/contrib/environment.md#data-retention-policy)
You may want to set up a data retention policy to automatically delete objects after a specified period.
```bash
export MINIO_ENDPOINT="127.0.0.1"
export MINIO_RETENTION_DAYS="30"
```
##### MinIO Sign Endpoint

##### [Audit Logging](https://github.com/openimsdk/open-im-server/blob/main/docs/contrib/environment.md#audit-logging)
For direct external access to stored content:
Enable audit logging to keep track of access and changes to your data.
```bash
export MINIO_SIGN_ENDPOINT=127.0.0.1:10005
export MINIO_AUDIT="on"
```
##### Modifying MinIO's Port
#### 1.4.6. <a name='Troubleshootinghttps:github.comopenimsdkopen-im-serverblobmaindocscontribenvironment.mdtroubleshooting'></a>[Troubleshooting](https://github.com/openimsdk/open-im-server/blob/main/docs/contrib/environment.md#troubleshooting)
If you need to adjust MinIO's port from the default:
##### [Debug Mode](https://github.com/openimsdk/open-im-server/blob/main/docs/contrib/environment.md#debug-mode)
In case of issues, you may enable debug mode to get more detailed logs to assist in troubleshooting.
```bash
export MINIO_PORT="10005"
export MINIO_DEBUG="on"
```
#### Applying the Configuration
#### 1.4.7. <a name='Conclusionhttps:github.comopenimsdkopen-im-serverblobmaindocscontribenvironment.mdconclusion'></a>[Conclusion](https://github.com/openimsdk/open-im-server/blob/main/docs/contrib/environment.md#conclusion)
After setting your desired environment variables, restart the MinIO server to apply the changes.
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.
#### Verification
#### 1.4.8. <a name='AdditionalResourceshttps:github.comopenimsdkopen-im-serverblobmaindocscontribenvironment.mdadditional-resources'></a>[Additional Resources](https://github.com/openimsdk/open-im-server/blob/main/docs/contrib/environment.md#additional-resources)
It's crucial to verify the configurations by checking the connectivity between your application and MinIO using the set API URL and ensuring that the data can be directly accessed using the `signEndpoint`.
