We installed the Bitrix virtual machine on centos mini, installed it on the second machine, and saw that everything was fine. But we had a problem with the system administrator, and he said that we must install a full-fledged firewall on the host machine. And we set yum install firewalld systemctl unmask firewalld systemctl enable firewalld systemctl starts firewalld And our sirouterlogin te crashed and we don't know what ports we need to open to make this miracle come to life again. Help kind people, open the knowledge of which ports you need to open this beast so that the site comes to life and the pool w 192.168.0.1 orks. And we installed memcached, mgmt, mysql_master_1, sphinx and web on the main machine and memcached, mysql_slave_2 and sphinx on the second machine.
