Hi!
It calls the following code:
-------
static void set_user(const char *user)
{
struct passwd *ent;
// don't bother if we aren't superuser
if(geteuid())
return;
if(!(ent = getpwnam(user))) <-- fails here
{
sql_perror("getpwnam");
unireg_abort(1);
}
if (setgid(ent->pw_gid) == -1)
{
sql_perror("setgid");
unireg_abort(1);
}
if (setuid(ent->pw_uid) == -1)
{
sql_perror("setuid");
unireg_abort(1);
}
}
-----------
I have now idea why getpwnam fails with 'success'.
Magnus; Are you sure that you have a user named 'mysql' ?
Try typing:
id mysql
