I have a CentOS 7 box with multiple IP address on the same NIC. One IP uses 443 for ssh and I want the other IP to use 443 for the web server. SELinux won't let httpd startup saying:
(13)Permission denied: AH00072: make_sock: could not bind to address MYIPADDRESS:443
I have both services setup to specifically listen on only the relevant IP addresses via Listen arguments in their relevant config files. Before I just turn off SELinux is there a way to allow both? My config SELinux currently looks like:
# semanage port -l | grep 443
http_port_t tcp 80, 81, 443, 488, 8008, 8009, 8443, 9000
pki_ca_port_t tcp 829, 9180, 9701, 9443-9447
pki_kra_port_t tcp 10180, 10701, 10443-10446
pki_ocsp_port_t tcp 11180, 11701, 11443-11446
pki_tks_port_t tcp 13180, 13701, 13443-13446
ssh_port_t tcp 443, 22
