MySQL Error 3160: Secure Transport Configuration Missing
Description
This error indicates that the MySQL server is configured to require secure connections (SSL or Shared Memory) but cannot find any such transport methods enabled or properly set up. It typically occurs when the `require_secure_transport` system variable is ON, but the server lacks the necessary SSL/TLS certificates, keys, or Shared Memory configurations.
Error Message
No secure transports (SSL or Shared Memory) are configured, unable to set --require_secure_transport=ON.
Known Causes
4 known causesSSL/TLS Configuration Missing
The MySQL server is not configured with the necessary SSL/TLS certificates and keys, preventing secure connections from being established.
Shared Memory Not Enabled (Windows)
On Windows systems, the MySQL server is not set up to use Shared Memory for local secure connections, which is a potential secure transport option.
`require_secure_transport` Enabled Prematurely
The `require_secure_transport` system variable is set to ON, but the underlying server infrastructure for SSL/TLS or Shared Memory is not yet in place.
Incorrect Server Startup Options
The MySQL server was started with command-line options or configuration file settings that implicitly or explicitly demand secure transport without having it configured.
Solutions
3 solutions available1. Disable Secure Transport Requirement Temporarily easy
Quickly bypass the error by disabling the secure transport requirement.
1
Locate your MySQL configuration file (e.g., `my.cnf` or `my.ini`). The location varies by operating system and installation method.
2
Open the configuration file in a text editor.
3
Find the `[mysqld]` section. If it doesn't exist, create it.
[mysqld]4
Comment out or remove the line `--require_secure_transport=ON`.
# --require_secure_transport=ON5
Save the configuration file.
6
Restart the MySQL server for the changes to take effect.
# For systemd-based systems (e.g., Ubuntu 15.04+, CentOS 7+):
sudo systemctl restart mysql
# For older init.d systems:
sudo service mysql restart2. Configure SSL for Secure Transport advanced
Enable SSL to meet the secure transport requirement.
1
Generate or obtain SSL certificates and keys. You'll need a Certificate Authority (CA) certificate, a server certificate, and a server private key.
2
Place the certificate and key files in a secure directory on your MySQL server. For example, `/etc/mysql/ssl/`.
3
Locate your MySQL configuration file (e.g., `my.cnf` or `my.ini`).
4
Open the configuration file in a text editor.
5
Add or modify the following lines within the `[mysqld]` section to point to your SSL files:
[mysqld]
ssl_ca=/etc/mysql/ssl/ca.pem
ssl_cert=/etc/mysql/ssl/server-cert.pem
ssl_key=/etc/mysql/ssl/server-key.pem
require_secure_transport=ON6
Ensure the MySQL user running the server process has read permissions for these files.
sudo chown mysql:mysql /etc/mysql/ssl/*
sudo chmod 600 /etc/mysql/ssl/*7
Save the configuration file.
8
Restart the MySQL server.
# For systemd-based systems (e.g., Ubuntu 15.04+, CentOS 7+):
sudo systemctl restart mysql
# For older init.d systems:
sudo service mysql restart9
Verify that clients can connect using SSL. You may need to configure client SSL parameters as well.
3. Configure Shared Memory for Secure Transport (Windows Only) medium
Enable shared memory for secure transport on Windows systems.
1
Ensure your MySQL installation supports shared memory. This is typically enabled by default on Windows.
2
Locate your MySQL configuration file (`my.ini`) in the MySQL installation directory.
3
Open the configuration file in a text editor.
4
In the `[mysqld]` section, ensure the following lines are present and uncommented:
[mysqld]
shared_memory
require_secure_transport=ON5
Save the configuration file.
6
Restart the MySQL service.
Open Services (services.msc) -> Find your MySQL service -> Right-click -> Restart.
