Running Liwan as a Service

Liwan can be run as a service on most operating systems. This allows you to start Liwan automatically when your server boots and manage it using the system’s service manager. Systemd is the most common and is used by most modern Linux distributions. Another popular init system is OpenRC, which is used by Gentoo and Alpine Linux.

systemd

1. Creating the service
   To run Liwan as a service using systemd, create a new service file in /etc/systemd/system/liwan.service with the following content:

   /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 with your username 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. If this is the first time you are running Liwan, you can find a link to set up your account in the logs.

OpenRC

1. Creating the service
   To run Liwan as a service using OpenRC, create a new service script in /etc/init.d/liwan with the following content:

    #!/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"
    capabilites="^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 with your username 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
   Starting the service After creating the service script, add the service 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. If this is the first time you are running Liwan, you can find a link to set up your account in the logs.
