I can suggest the following at this point:
1) Ensure the process is infact running. I am not familiar with the Windows OS, but on *nix I would do:
Code:
$ ps -aux | grep mysql
2) If the MySQL process is running, is it listening for connections? You should be able to use the
netstat command for that. Again, in *nix I would use:
Code:
$ netstat -natup | grep LISTEN | grep 3306
This only means: "is there something listening on port 3306?".
3) If both the previous checks out, try the command line mysql client. In a DOS box ( you still have those, yes? ) simply type:
. You should get something similar to:
Code:
$ mysql
Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 1 to server version: 4.0.11a-gamma
Type 'help;' or '\h' for help. Type '\c' to clear the buffer.
mysql> show databases;
+----------+
| Database |
+----------+
| test |
+----------+
1 row in set (0.14 sec)
mysql>
PS: You might need to to specify the path to the mysql binary.
If all works, then your problem is purely
Navicat related, in which case you should contact their tech support. If you have problems with anything from 1 to 3, your problem is MySQL related - and we then need to dig a bit more.
