Many ports will shut down a running instance of themselves when upgraded
like this specifically to avoid the sort of complications that can occur
when the running image does not match what is on disk.
mysql does, apache doesn't. =20
So upgrade mysql-server last thing before you reboot. Although I know yo=
u're
not using portupgrade, this snippet from pkgtools.conf has been a blessin=
g in
minimizing outage lengths during updates on live servers:
AFTERINSTALL =3D {
'*' =3D> proc { |origin|
cmd_start_rc(origin)
},
}
Of couse, the best course of action is to plan sufficient downtime that y=
ou
can do the upgrades comfortably plus recover from any number of ways thin=
gs
might go wrong, but sometimes that simply isn't possible.
Cheers,
Matthew
