im running on CentOS 6.5 and actually trying to follow this tutorial (http://socketo.me/docs/deploy) on Websocket which says that I need to install Haproxy and run the following linux command :
sudo haproxy -f /etc/haproxy.cfg -p /var/run/haproxy.pid -D
The problem is that I get this message :
[ALERT] 015/013939 (22640) : Starting frontend public: cannot bind socket [0.0.0.0:80]
My "netstat -nat | grep 80 | grep LISTEN" returns :
tcp 0 0 212.227.96.81:80 0.0.0.0:* LISTEN
tcp 0 0 0.0.0.0:8880 0.0.0.0:* LISTEN
tcp 0 0 2001:8d8:86c:6e00::14:3b:80 :::* LISTEN
tcp 0 0 :::8880 :::* LISTEN
tcp 0 0 :::7080 :::* LISTEN
PS : 212.227.96.81 is the IP adress that pings on my domain name. What should I do exactly to resolve this ? Is it apache ? Because I restarted it and nothing. Thank you.
your web server is listing on port 80
tcp 0 0 212.227.96.81:80 0.0.0.0:* LISTEN
you need to change the Apache/webserver port to a different one. you can't bind haproxy and Apache on the same port on the same server
client send request to port 80 ---> HA-PROXY--->send request to apache (port 8080).
asssuming both running on the same server.
