Recently, I found myself in a situation where the SSSD service on my Ubuntu server crashed. This was kind of an issue because it meant that all authentication requests were denied. It took a call from an upset dev to figure out what the problem was and then I needed to login and manually restart the service. To prevent this from happening again, I decided to automate the process with a systemd unit file.
Steps to Automate restart of SSSD service on Ubuntu:
Create a new file:
/etc/systemd/system/multi-user.target.wants/sssd.service
Add the following to the file:
[Unit]
Description=System Security Services Daemon
# SSSD must be running before we permit user sessions
Before=systemd-user-sessions.service nss-user-lookup.target autofs.service
Wants=nss-user-lookup.target
[Service]
ExecStart=/usr/sbin/sssd -i -f
Type=notify
NotifyAccess=main
PIDFile=/var/run/sssd.pid
Restart=always
RestartSec=120
[Install]
WantedBy=multi-user.target
sudo systemctl | grep -i "sssd*"
Save and close the file. Reload your systemd daemon to apply this new configuration: sudo systemctl daemon-reload
sudo systemctl start sssd.service
That's it your are done. Happy automating.
