Resolving PHPMyAdmin error code 200

PHPMyAdmin error code 200 means that the connection to the MySQL server cannot be established. The steps to resolve this error are as follows:

1. Check the MySQL service status

• to see if the MySQL service is running.
• If it is not running, start the service and try to connect again.

2. Check username and password

• Make sure the username and password used in PHPMyAdmin match those of the MySQL server.
• If there is no match, update the connection information and try to connect again.

3. Check the MySQL binding address

• MySQL only listens for localhost connections by default. If PHPMyAdmin is on a different server than the MySQL server, check whether the MySQL server's bind address allows external connections.
• Edit the MySQL configuration file (my.ini or my.cnf) and make sure bind-address is set to 0.0.0.0 or the specific IP address you want to allow connections to.

4. Check the firewall settings

• Check whether the system firewall allows connections from the PHPMyAdmin server to the MySQL server.
• If not allowed, open the MySQL port (usually 3306) for inbound connections.

5. Check the MySQL socket file

• If you use a socket file to connect to MySQL, make sure the socket file exists and Writable.
• If it does not exist, create the socket file and give appropriate permissions.

6. Restart PHPMyAdmin

• After making changes to PHPMyAdmin, restart PHPMyAdmin.
• This will ensure that PHPMyAdmin is reloaded with the updated configuration.

7. Other potential issues

• Incompatible PHP version
• Missing or misconfigured PHP extension
• NetworkProblems

After trying the above steps, if you still receive error code 200, check the system logs or consult the MySQL documentation for other possible solutions.
