[Kea-users] ISC-KEA with MariaDB on Debian Buster Startup Sequence

[PeterP]

I suspect that you are generally correct, but I modelled my entries on what was already in the file, which had ...After=network-online.targetAfter=time-sync.targetalready defined over separate lines.I'll monitor it over the next week or so and if it starts failing to start again.  If it does, I'll try putting the entries on a single line as you have recommended.Thank you for your help.PeterP.On 22 Sep 2021, at 15:04, perl-list <perl-list at network1.net> wrote:I think you just want to have one After= line like so:After=network-online.target time-sync.target mysql.service mariadb.serviceat least thats how the radiusd.service file was on our server here.  This is on Redhat Enterprise Linux 8.x but it should be similar systemd implementations.----- Original Message -----From: "PeterP" <looms_pastels_0f_kea at icloud.com>To: "kea-users" <kea-users at lists.isc.org>Sent: Wednesday, September 22, 2021 9:44:02 AMSubject: Re: [Kea-users] ISC-KEA with MariaDB on Debian Buster Startup SequenceMade the change and rebooted and it seems to have worked.File is "/usr/lib/systemd/system/isc-kea-dhcp4-server.service".

Everything is up to date as regards versions, at leastas far as I am aware, as I run global updates every few days.I am having a problem with the isc-kea-dhcp4-server.service. Whenever there is asystem reboot, this service fails to start. When I manually restart it later,it works fine. As far as I can trace, it's a startup sequence issue in relationto having MariaDB as a back-end for Kea. I looks like Kea is starting first,looking for the MariaDB service and failing because MariaDB has yet to start.How can I change the start order so that the isc-kea-dhcp4-server.servicedoesn't start until the MariaDB service is up and running?I expect I will have the same issue with the isc-kea-dhcp6-server.service when Ieventually start to use it.Thank you,PeterP._______________________________________________ISC funds the development of this software with paid support subscriptions.Contact us at https://www.isc.org/contact/ for more information.To unsubscribe visit https://lists.isc.org/mailman/listinfo/kea-users.Kea-users mailing listKea-users at lists.isc.orghttps://lists.isc.org/mailman/listinfo/kea-users_______________________________________________ISC funds the development of this software with paid support subscriptions.Contact us at https://www.isc.org/contact/ for more information.To unsubscribe visit https://lists.isc.org/mailman/listinfo/kea-users.Kea-users mailing listKea-users at lists.isc.orghttps://lists.isc.org/mailman/listinfo/kea-users_______________________________________________ISC funds the development of this software with paid support subscriptions.Contact us at https://www.isc.org/contact/ for more information.To unsubscribe visit https://lists.isc.org/mailman/listinfo/kea-users.Kea-users mailing listKea-users at lists.isc.orghttps://lists.isc.org/mailman/listinfo/kea-users_______________________________________________ISC funds the development of this software with paid support subscriptions.Contact us at https://www.isc.org/contact/ for more information.To unsubscribe visit https://lists.isc.org/mailman/listinfo/kea-users.Kea-users mailing listKea-users at lists.isc.orghttps://lists.isc.org/mailman/listinfo/kea-users_______________________________________________ISC funds the development of this software with paid support subscriptions.
