-====== Start Synchronet BBS from Systemd ======+====== Start, Control, and Monitor Synchronet BBS using systemd ======
-If you run modern GNU/Linux distributionsyou can found [[https://en.wikipedia.org/wiki/Systemd|Systemd]] as init system (like Debian, Fedora and others).+If you run modern GNU/Linux distributionit is likely using [[https://en.wikipedia.org/wiki/Systemd|systemd]] as its "init system" for starting and controlling system services/daemons. Installing Synchronet into systemd is recommended for such systems so that Synchronet will start upon system boot and provide all the control and monitoring expected of an integrated system service.
-Instead of use the old /etc/init.d/sbbs.service init script, you can create a systemd services unit file:+===== Install =====
-Create and edit the follow files (please correct your ExecStart path and User/Group as you need)+If you've installed Synchronet, you should already have the required [[https://gitlab.synchro.net/main/sbbs/-/raw/master/install/systemd/sbbs.service|system service unit file]] in the following location: 
 +  sbbs/repo/install/systemd/sbbs.service 
 +Read [[https://gitlab.synchro.net/main/sbbs/-/raw/master/install/systemd/sbbs.service|this file]] for the current instructions on how to install and configure it, but here's a summary for quick reference:
-===== Debian ===== +  - Copy or symlink the ''sbbs.service'' file to the correct directory, e.g. for Debian/Ubuntu Linux, that would be: ''/lib/systemd/system'' 
-/etc/default/sbbs +  - Enable the BBS service by running: ''sudo systemctl enable sbbs'' 
-  SBBSCTRL=/sbbs/ctrl+  - To run the BBS service without rebooting, run: ''sudo systemctl start sbbs''
-/etc/systemd/system/sbbs.service  +Any necessary edits should be made using ''sudo systemctl edit sbbs'', thus creating the file: 
-  [Unit+  /etc/systemd/system/sbbs.service.d/override.conf 
-  Description=Synchronet BBS +This will allow you to integrate any future upstream changes to the ''sbbs.service'' file without losing your local changes. 
-  Documentation=man:sbbs + 
-  After=network.target+After editing the ''sbbs.service'' or ''overrride.conf'' file, execute the following command to tell systemd to reload the unit files: 
 +  sudo systemctl daemon-reload 
 +==== Recommended Tweaks to the Service Section ==== 
 +To allow core file generation (for crash/segfault debugging), add to the ''[Service]'' section of your service unit file: 
 +<file sbbs.service> 
 +==== Where is My Service File? ==== 
 +If you are already running Synchronet from systemd but can't remember where the config file is, the following commands will help. 
 +  systemctl show -p FragmentPath sbbs 
 +===== Control ===== 
 +To start the Synchronet service 
 +  systemctl start sbbs 
 +To restart (stop and then start) the Synchronet service 
 +  systemctl restart sbbs
-  [Service] +To stop the Synchronet service 
-  Restart=on-failure +  systemctl stop sbbs
-  EnvironmentFile=-/etc/default/sbbs +
-  ExecStart=/sbbs/exec/sbbs nd +
-  ExecReload=/bin/kill -HUP $MAINPID +
-  User=root +
-  Group=root+
-  [Install] +===== Monitor =====
-  WantedBy=multi-user.target+
 +Display the current Synchronet service status:
 +  systemctl status sbbs
 +Watch the current Synchronet service status in real-time:
 +  watch systemctl status sbbs
 +Read/search the log output of the Synchronet service:
 +  journalctl -u sbbs
 +Watch the log output of the Synchronet service in real-time:
 +  journalctl -f -u sbbs
-Finally, you must execute //systemd daemon-reload// for tell systemd te reload the unit file+==== Monitoring with Byobu (Tmux backend) ==== 
 +You can have a text mode dashboard for monitoring and configuring your BBS realtime by using Byobu with Tmux or GNU Screen backends. If you are using the Tmux backend. The following configuration splits your screen in three panes: one for SBBS log, other for UMONITOR and a last one for SCFG. Please note that this configuration assumes SBBSCTRL variable is set and that access permissions to the needed files are set for the current user.
-Test your setup:+Create the file ''$BYOBU_CONFIG_DIR/windows.tmux.sbbs'' with the following contents:
-  # systemctl status sbbs +  new-session sbbs ; 
-  ● sbbs.service Synchronet BBS +  new-window -n sbbs tail -n 50 -f /var/log/sbbs.log 
-     Loaded: loaded (/etc/systemd/system/sbbs.serviceenabled) +  split-window -h /sbbs/exec/umonitor 
-     Active: active (running) since lun 2016-11-21 14:39:53 ART24min ago +  split-window -t 1 -v /sbbs/exec/scfg ; 
-       Docs: man:sbbs +  set-option mouse on 
-    Process: 14393 ExecStart=/sbbs/exec/sbbs nd (code=exitedstatus=0/SUCCESS) + 
-   Main PID14393 (sbbs) +And then run: ''user@localhost:~$ BYOBU_WINDOWS=sbbs byobu'' 
-     CGroup/system.slice/sbbs.service + 
-             └─14393 /sbbs/exec/sbbs nd +If you want this to be your default environment when you log at your Synchronet serverthen write the configuration to the ''$BYOBU_CONFIG_DIR/windows.tmux'' file instead of ''$BYOBU_CONFIG_DIR/windows.tmux.sbbs'' 
-   + 
-  nov 21 14:39:53 scarlet systemd[1]: Started Synchronet BBS.+The following screenshot shows the result
 +If are using also **binkd** for FidoNet, this configuration will split the dashboard in 4 panes: 
 +  new-session sbbs ; 
 +  new-window -n sbbs tail -n 50 -f /var/log/sbbs.log ; 
 +  split-window -p 50 -h /sbbs/exec/umonitor ; 
 +  split-window -t 0 -p 20 -v tail -f /var/log/binkd.log ; 
 +  split-window -t -v /sbbs/exec/scfg ; 
 +  set-option mouse on
