Re: unable to start mysqld.service but command line works

[Bjørn Munch]

I see the first ERROR reported is that it gets permission denied when trying to create /tmp/data/auto.cnf and before that it's a warning that it can't create /tmp/data/mysqld_tmp_file_case_insensitive_test.lower-test .

Could it be that /tmp/data is not writable by the server? I think you'd get errno 2 if /tmp/data had to already exist but didn't.
