• If--log-error is not given,mysqld writes the error log to the console.

• If--log-error is given without naming a file,mysqld writes the error log to a file namedhost_name.err in the data directory.

• If--log-error is given to name a file,mysqld writes the error log to that file (with an.err suffix added if the name has no suffix). The file location is under the data directory unless an absolute path name is given to specify a different location.

• If--log-error is given in an option file in a[mysqld],[server], or[mysqld_safe] section, on systems that usemysqld_safe to start the server,mysqld_safe finds and uses the option, and passes it tomysqld.

It is common for Yum or APT package installations to configure an error log file location under/var/log with an option likelog-error=/var/log/mysqld.log in a server configuration file. Removing the path name from the option causes thehost_name.err file in the data directory to be used.
