.pid file extension
- MySQL pid file.
The .pid file is a text file which contains a single line. This records the pid (numeric process identifier) for the MySQL process.
Each time MySQL is started it will write to this file and overwrite any previous contents. The file will be empty if MySQL could not start (in which case the error which prevented it from starting will be recorded in a corresponding .err file).
The .pid file is normally named after the computer (but this can be changed), so its full name will normally be:
computer-nameis the name of the computer/server on which MySQL is being run.
