Prerequisites

The following prerequisites must be met before initiating the deployment. Also, it is important to note that you must have Sudo access to configure the LeapLogic AI prerequisites

Install Java 17 (JDK) and configure the JAVA_HOME environment variable so that the following command returns the correct JAVA path.

‘echo $JAVA_HOME’

Python 3.10 or later should be installed on the server with the following packages included:

langchain
langchain-core
langchain-community
langchain-text-splitters
langgraph
langgraph-prebuilt
chromadb
qdrant-client
langchain-qdrant
langchain-openai
langchain-aws
langchain-google-vertexai
anthropic
databricks-langchain
transformers
tokenizers
tiktoken
rank-bm25
sentence-transformers
boto3
botocore
google-auth
google-cloud-aiplatform
pydantic
PyYAML
requests
lxml
unstructured
langchain-unstructured
sqlfluff
langgraph-checkpoint-sqlite

You can list all the above packages in a requirements.txt file and install them in one go using the following command:

pip3.10 install -r requirements.txt

SQLite version should be 3.35 or higher.

To upgrade SQLite when the version is below 3.35, execute the following commands:

cd /usr/local
sudo wget https://www.sqlite.org/2024/sqlite-autoconf3460000.tar.gz
sudo tar -xvzf sqlite-autoconf-3460000.tar.gz
cd sqlite-autoconf-3460000
./configure –prefix=/usr/local
make -j$(nproc)
sudo make install
export PATH=/usr/local/bin:$PATH (Skip if not required)
sqlite3 –version

To rebuild Python to link new SQLite, execute the following commands:

Go to the python path: cd /usr/local/Python-3.10.13
./configure –enable-optimizations –enable-loadable-sqliteextensions
make -j$(nproc)
sudo make altinstall
echo “/usr/local/lib” | sudo tee /etc/ld.so.conf.d/localsqlite.conf
sudo ldconfig

To verify the SQLite version, run:

python3.10 -c “import sqlite3; print(sqlite3.sqlite_version)”

One of the following three databases is required. LeapLogic AI has been certified with these database options:

Postgres 15: Postgres database should be installed on the server, and you must have access to create a database.

Note:

If LeapLogic is already installed on the server, use LeapLogic’s Postgres.

AWS MySQL RDS (version 8.0.42): The RDS endpoint and credentials are required to establish a connection.
AWS Postgres RDS (version 13.20): The RDS endpoint and credentials are required to establish a connection.
