systemctl failed to get Dbus connection: No connection to service manager
 

Hi every body
I works on buildroot for some days.
now I have an issue with systemctl.
in fact, I want to initialize and start lighttpd.
according to this page, I want to run "systemctl start lighttpd" to initialize lighttpd server.
but I face with "systemctl failed to get Dbus connection: No connection to service manager" error.
I have searched and find that I must boot with systemd.
I must create some symlinks to boot with systemd

when I run "cat /proc/1/comm" I have received: "init" instead of systemd.

after I create symlinks like " ln -sf /usr/lib/systemd/systemd /sbin/init" and reboot the system, my boot crash before init step.

have any one any suggestion?!
thanks from all

dbus needs to be running first.

The "cat /proc/1/comm" will always show "init", as that is the name the kernel uses to start init. The kernel init process does an exec of /sbin/init, which in a systemd environment is a symbolic link to /bin/systemd, so the command to invoke systemd is init.
