[MDEV-8543] mysql.server script not correctly handle --pid-file. Created: 2015-07-25  Updated: 2015-10-28  Resolved: 2015-10-28

CentOS 7.1 x64

Sprint: 10.0.22

 Description   

If I start mysql with --pid-file argument:

service mysql start --pid-file=/var/lib/mysql/1234.pid

I can not stop it with
service mysql stop --pid-file=/var/lib/mysql/1234.pid

I got this error:
MySQL server PID file could not be found!

This is because parse_server_arguments function in script does not parse --pid-file, the variable $mysqld_pid_file_path will always be empty.

Thanks.

This seems to be intentional. The comment in the script says

other_args="$*"   # uncommon, but needed when called from an RPM upgrade action
 
           # Expected: "--skip-networking --skip-grant-tables"
 
           # They are not checked here, intentionally, as it is the responsibility
 
           # of the "spec" file author to give correct arguments only.

So, these arguments are only supported when mysql.server is invoked from a spec file, they shouldn't be used directly.

On the other hand, this code is not used for years, I can as well remove support for mysql.server arguments completely.
