We are facing problem in starting mysql [MySQL 3.23.58] in Solaris 8
platform and exception is thrown 'Fatal error: Can't change to run as
user 'mysql' ; Please check that the user exists!'.
I have tried using using either root or specific user.
If I check MySQL logs by viewing
/opt/mysql/data/<hostname>.err
040119 09:34:32 mysqld started
Fatal error: Can't change to run as user 'mysql' ; Please check that
the
user exists!
040119 9:34:32 Aborting
040119 9:34:32 /opt/mysql/bin/mysqld: Shutdown Complete
040119 09:34:32 mysqld ended
I've tried several times to install it, but still get the same error.
Any
clue on that problem ?
Any help to solve this problem is really appreciated.
Regards,
Chithuu ..!

It looks like your MySQL server process is hitting a problem when
it tries to change its user id to that of the user 'mysql'.
There are two possible reasons for this:
1. You're starting the server process as a user who isn't 'root',
so the user doesn't have the necessary privilege to change
the UID of the server process.
-- OR --
2. You *are* starting the server process as 'root', but your
system doesn't have a user called 'mysql', so the process
is trying, and failing, change its UID to a user that
doesn't exist.
Try "finger mysql" to see whether you actually have a user named
'mysql'.
Thinking about it, there are other possibilities, assuming that
you *do* have a user named 'mysql'.
3. The 'mysql' user doesn't have a home directory, or for some
reason that user doesn't have write-access to its home directory.
4. The 'mysql' user doesn't have the necessary access privileges
to /opt/mysql and all of its sub-directories.
However, my money is on reason 2.
