One of the most frequent errors when configuring Dedecms database connection is entering an incorrect username or password. Users should carefully verify these credentials to ensure accuracy.
An incorrect database server address is another common reason for connection failures. Whether it's an IP address or domain name, any mistake will prevent the database from connecting. Users are advised to confirm the server address is correct.
Entering the wrong database name during configuration also leads to connection failure. Users should ensure the database name matches the actual database exactly.
Wrong port number settings can cause connection issues. Check that the port number in the configuration file matches the database server's port.
Network instability or heavy server load can cause connection timeouts. Users may increase the connection timeout or optimize the network environment to reduce these failures.
Ensure that the username and password are entered correctly, with no extra spaces or typos.
Use ping or telnet commands to test if the database server address is reachable and correctly configured.
Review the database list or consult the server administrator to confirm the exact database name.
Ensure the port number in the configuration matches the one used by the database server.
Extend the connection timeout duration appropriately to handle network instability or server load.
Although Dedecms database connection failures are common, systematically checking each configuration parameter usually helps quickly identify and fix the problem. Properly setting the username, password, server address, database name, port, and adjusting timeout settings ensures stable website operation.
