Re: [Samba] Managing samba ad dc with systemd




Hai Igor,

No, that not normal, and this is and old bug in the start/stop. 
Entered after samba started to use preforking i believe. 

See the Unit setup below. 
Note, i added bind9.service here, because i use bind and i want bind to start before samba-ad.
Just keep it there, if you change you samba to samba+bind_dlz, then you services are starting in the correct order. 

This part: 
# systemctl mask smbd nmbd winbind 
# systemctl disable smbd nmbd winbind 

That should be fine, but if there are left overs from a packages install, you might notice that. 
Then check also if samba.service exist, if so, remove it, not used anymore. 

smbd nmbd winbind samba-ad

As you see i've added bind9.service also to After, that is, if you want/are useing bind9_dlz with samba
Than bind needs to start before samba, just keep it there it wont hurt anything.

So for you i suggest this systemd setup.
If you can verify it, i'll make some changes in the wiki. 


#/etc/systemd/system/samba-ad-dc.service
[Unit]
Description=Samba AD Daemon
Wants=network-online.target
After=network.target network-online.target bind9.service

[Service]
Type=notify
NotifyAccess=all
ExecStart=/usr/local/samba/sbin/samba -D
PIDFile=/usr/local/samba/var/run/samba.pid
ExecReload=/bin/kill -HUP $MAINPID

[Install]
WantedBy=multi-user.target

After the change

systemctl daemon-reload
systemctl stop samba-ad-dc
systemctl start samba-ad-dc
