## Docker Deployment - Manually Update MongoDB
1. Modify the mongo section in docker-compose.yml by adding the `command` and `entrypoint` fields:
```yml
mongo:
image: mongo:5.0.18
# image: registry.cn-hangzhou.aliyuncs.com/fastgpt/mongo:5.0.18 # Alibaba Cloud
container_name: mongo
ports:
- 27017:27017
networks:
- fastgpt
command: mongod --keyFile /data/mongodb.key --replSet rs0
environment:
# Make sure the password matches your previous configuration
- MONGO_INITDB_ROOT_USERNAME=username
- MONGO_INITDB_ROOT_PASSWORD=password
volumes:
- ./mongo/data:/data/db
entrypoint:
- bash
- -c
- |
openssl rand -base64 128 > /data/mongodb.key
chmod 400 /data/mongodb.key
chown 999:999 /data/mongodb.key
echo 'const isInited = rs.status().ok === 1
if(!isInited){
rs.initiate({
_id: "rs0",
members: [
{ _id: 0, host: "mongo:27017" }
]
})
}' > /data/initReplicaSet.js
# Start MongoDB service
exec docker-entrypoint.sh "$@" &
# Wait for MongoDB to start
until mongo -u myusername -p mypassword --authenticationDatabase admin --eval "print('waited for connection')" > /dev/null 2>&1; do
echo "Waiting for MongoDB to start..."
sleep 2
done
# Run the replica set initialization script
mongo -u myusername -p mypassword --authenticationDatabase admin /data/initReplicaSet.js
# Wait for the MongoDB process started by docker-entrypoint.sh
wait $!
```
2. Restart MongoDB
```bash
# Restart Mongo
docker-compose down
docker-compose up -d
```
## Sealos Deployment - No MongoDB Update Required
## Update Configuration File
Removed duplicate model configurations. All LLM models are now consolidated into a single property. [View the latest configuration file](/docs/self-host/config/json/)
## Commercial Edition Initialization
Commercial edition users need to run an initialization to format team information.
Send 1 HTTP request (replace `{{rootkey}}` with the `rootkey` from your environment variables, and `{{host}}` with your commercial edition domain):
```bash
curl --location --request POST 'https://{{host}}/api/init/v468' \
--header 'rootkey: {{rootkey}}' \
--header 'Content-Type: application/json'
```
This will initialize the billing system. For internal use, you can increase the free storage quota.
## V4.6.8 Release Notes
1. New - Knowledge Base search merge module.
2. New - Redesigned HTTP module with more flexible parameter input. Supports automatic input/output data type conversion (e.g., JSON output is automatically converted to string type for use by other modules). Additional examples are available in the documentation.
3. Improved - Query completion. Query completion is now built into the Knowledge Base Search module, enabling both "reference resolution" and "query expansion" in a single pass. See [Knowledge Base Search Introduction](/docs/introduction/guide/dashboard/workflow/dataset_search/) for details.
4. Improved - LLM model configuration no longer distinguishes between chat, classification, and extraction models. Default parameters per model are now supported via `defaultConfig` to avoid parameter conflicts between different models.
5. Improved - Streaming response, inspired by `ChatNextWeb`'s streaming implementation for smoother output. This may also fix previously reported issues with garbled text and interruptions that resolved after refreshing.
6. Fixed - Voice input file upload failure.
7. Fixed - Chat box regeneration not working.
