Running liwan as a Service

liwan can run as a service so it starts automatically when your server boots. This page shows examples for systemd and OpenRC.

systemd

1. Creating the service
   Create /etc/systemd/system/liwan.service:

   /etc/systemd/system/liwan.service

   [Unit]
   Description=liwan web analytics
   After=network.target
   
   [Service]
   # Replace `yourusername` with your username
   ExecStart=/home/yourusername/.local/bin/liwan
   Restart=on-failure
   User=yourusername
   
   [Install]
   WantedBy=multi-user.target

   Replace yourusername and adjust the paths to match your setup. To generate a configuration file, you can run liwan generate-config -o ~/.config/liwan/liwan.config.toml.

2. Starting the service
   After creating the service file, reload the systemd daemon and start the service:

   # Reload the systemd daemon
   sudo systemctl daemon-reload
   # Enable the service to start automatically on boot
   sudo systemctl enable liwan
   # Start the service
   sudo systemctl start liwan

3. Checking the status
   You can now check the status of the service using systemctl status liwan and view the logs using journalctl -u liwan. The logs contain the initial setup URL.

OpenRC

1. Creating the service
   Create /etc/init.d/liwan:

   /etc/init.d/liwan

   #!/sbin/openrc-run
   
   name="liwan"
   description="liwan web analytics"
   
   command_user="yourusername"
   command="/home/${command_user}/.local/bin/liwan"
   command_background=true
   pidfile="/run/${RC_SVCNAME}.pid"
   capabilities="^cap_net_bind_service"
   output_log="/var/log/liwan/liwan.log"
   error_log="/var/log/liwan/liwan.err"
   
   depend() {
       need net
       after firewall
   }
   
   start_pre() {
       checkpath --directory --owner $command_user:$command_user --mode 0775 \
               /run/$RC_SVCNAME /var/log/$RC_SVCNAME
   }

   Replace yourusername and adjust the paths to match your setup. Make sure the script is executable:

   chmod +x /etc/init.d/liwan

   To generate an example configuration file, you can run liwan generate-config -o ~/.config/liwan/liwan.config.toml.

2. Starting the service
   After creating the service script, add it to the default runlevel and start it:

   # Add the service to the default runlevel
   rc-update add liwan default
   # Start the service
   rc-service liwan start

3. Checking the status
   You can now check the status of the service using rc-service liwan status and view the logs using tail -f /var/log/liwan/liwan.log. The logs contain the initial setup URL.
