How to configure MatrixOne SSL connection

Overview

This document describes how to configure your MatrixOne server to use SSL for database connections. After you secure your MatrixOne connections, malicious users cannot intercept your traffic.

Configure MatrixOne SSL connections

Create the directory to store the SSL keys

To create the directory that will contain the SSL keys, perform the following steps:

  1. Log into your server via SSH. Check if you have the mysql_ssl_rsa_setup tool in place. Usually if you have installed MySQL, the mysql_ssl_rsa_setup binary will also be installed.

    If you try to execute this command mysql_ssl_rsa_setup and you see this following message, it means you have installed it. If not, please install MySQL first, and this mysql_ssl_rsa_setup will be installed along. You can also check the path of mysql_ssl_rsa_setup binary file with whereis mysql_ssl_rsa_setup.

    [pcusername@VM-0-12-centos matrixone]$ mysql_ssl_rsa_setup
    2022-10-19 10:57:30 [ERROR]   Failed to access directory pointed by --datadir. Please make sure that directory exists and is accessible by mysql_ssl_rsa_setup. Supplied value : /var/lib/mysql
    [pcusername@VM-0-12-centos matrixone]$ whereis mysql_ssl_rsa_setup
    mysql_ssl_rsa_setup: /usr/bin/mysql_ssl_rsa_setup /usr/share/man/man1/mysql_ssl_rsa_setup.1.gz
    
  2. Create an SSL key storage directory that MatrixOne can access. For example, run the mkdir /home/user/mo_keys command to create a mo_keys directory.

Create the SSL keys

To create the SSL keys, perform the following steps:

  1. Run the following commands to create the Certificate Authority (CA) keys:

    mysql_ssl_rsa_setup --datadir=/home/user/mo_keys
    

    You'll see in this folder a list of .pem files.

    /mo_keys
    ├── ca-key.pem
    ├── ca.pem
    ├── client-cert.pem
    ├── client-key.pem
    ├── private_key.pem
    ├── public_key.pem
    ├── server-cert.pem
    └── server-key.pem

  2. Insert the following lines in the [cn.frontend] section of the etc /launch-with-proxy/cn.toml file in MatrixOne folder:

    [cn.frontend]
    enableTls = true
    tlsCertFile = "/home/user/mo_keys/server-cert.pem"
    tlsKeyFile = "/home/user/mo_keys/server-key.pem"
    tlsCaFile = "/home/user/mo_keys/ca.pem"
    

    If [cn.frontend] section doesn't exist in the MatrixOne system setting file, you can just create one with the above settings.

Test the SSL configuration

To test the SSL configuration, perform the following steps:

  1. Launch MatrixOne service. Please refer to Deploy standalone MatrixOne.

  2. Connect to MatrixOne service by MySQL client:

    mysql -h IP_ADDRESS -P 6001 -uroot -p111
    
  3. After you connect, run the status command. The output will resemble the following example:

    mysql> status
