I have just installed thruk on same centos7 box(with icinga 1.10 running) using labs_consol_stable yum repository and installed mk-livestatus from
source, and configure broker_module as broker_module=/usr/local/lib/mk-livestatus/livestatus.o /etc/icinga/live
I also setup the xinetd to listen to 6557 but when i go to /thruk url it shows "You are not authorized. It seems like you are not authorized." error message directly without authentication form.
