Hi Aleksandar, I have made a few changes to the haproxy.cfg file and following are the outputs :-
HAPROXY.cfg #--------------------------------------------------------------------- # Example configuration for a possible web application. See the # full configuration options online. # # http://haproxy.1wt.eu/download/1.4/doc/configuration.txt # #--------------------------------------------------------------------- #--------------------------------------------------------------------- # Global settings #--------------------------------------------------------------------- global # to have these messages end up in /var/log/haproxy.log you will # need to: # # 1) configure syslog to accept network log events. This is done # by adding the '-r' option to the SYSLOGD_OPTIONS in # /etc/sysconfig/syslog # # 2) configure local2 events to go to the /var/log/haproxy.log # file. A line like the following can be added to # /etc/sysconfig/syslog # # local2.* /var/log/haproxy.log # log 127.0.0.1 local2 chroot /var/lib/haproxy pidfile /var/run/haproxy.pid maxconn 4000 user haproxy group haproxy daemon # turn on stats unix socket stats socket /var/lib/haproxy/stats #--------------------------------------------------------------------- # common defaults that all the 'listen' and 'backend' sections will # use if not designated in their block #--------------------------------------------------------------------- defaults mode http log global option httplog option dontlognull option http-server-close option forwardfor except 127.0.0.0/8 option redispatch retries 3 timeout http-request 10s timeout queue 1m timeout connect 10s timeout client 1m timeout server 1m timeout http-keep-alive 10s timeout check 10s maxconn 3000 #--------------------------------------------------------------------- # main frontend which proxys to the backends #--------------------------------------------------------------------- frontend main *:5000 acl url_static path_beg -i /static /images /javascript /stylesheets acl url_static path_end -i .jpg .gif .png .css .js use_backend static if url_static default_backend app #--------------------------------------------------------------------- # static backend for serving up images, stylesheets and such #--------------------------------------------------------------------- backend static balance roundrobin server static 127.0.0.1:4331 check #--------------------------------------------------------------------- # round robin balancing between the various backends #--------------------------------------------------------------------- backend app balance roundrobin server app1 127.0.0.1:5001 check server app2 127.0.0.1:5002 check server app3 127.0.0.1:5003 check server app4 127.0.0.1:5004 check frontend haproxy_inbound bind *:443 *[CHANGED PORT]* default_backend haproxy_httpd backend haproxy_httpd balance roundrobin mode http #(NOT NEEDED IF DEFINED IN DEFAULTS) option httpchk server lxapp14070.dc.corp.telstra.com 10.195.70.12:443 check * [Host and Port Changed]* server lxapp14071.dc.corp.telstra.com 10.195.70.13:443 check *[Host and Port Changed] * 1.*curl -v --max-time 30 127.0.0.1:5001 <http://127.0.0.1:5001>* [root@lxapp14012 ~]# curl -v --max-time 30 127.0.0.1:5001 * About to connect() to 127.0.0.1 port 5001 (#0) * Trying 127.0.0.1... * Connection refused * Failed connect to 127.0.0.1:5001; Connection refused * Closing connection 0 curl: (7) Failed connect to 127.0.0.1:5001; Connection refused 2. *curl -v --max-time 30 10.195.70.12:443 <http://10.195.70.12:443>* [root@lxapp14012 haproxy]# curl -v --max-time 30 10.195.70.12:443 * About to connect() to 10.195.70.12 port 443 (#0) * Trying 10.195.70.12... * Connected to 10.195.70.12 (10.195.70.12) port 443 (#0) > GET / HTTP/1.1 > User-Agent: curl/7.29.0 > Host: 10.195.70.12:443 > Accept: */* > * Empty reply from server * Connection #0 to host 10.195.70.12 left intact curl: (52) Empty reply from server 3.*curl -v --max-time 30 10.195.70.13:443 <http://10.195.70.13:443>* [root@lxapp14012 haproxy]# curl -v --max-time 30 10.195.70.13:443* About to connect() to 10.195.70.13 port 443 (#0) * Trying 10.195.70.13... * Connected to 10.195.70.13 (10.195.70.13) port 443 (#0) > GET / HTTP/1.1 > User-Agent: curl/7.29.0 > Host: 10.195.70.13:443 > Accept: */* > * Empty reply from server * Connection #0 to host 10.195.70.13 left intact curl: (52) Empty reply from server *HA-Proxy version 1.5.18 2016/05/10* --- Will update it now [root@lxapp14012 haproxy]# haproxy -c -f /etc/haproxy/haproxy.cfg Configuration file is valid Also now when I run the command haproxy -db -f /etc/haproxy/haproxy.cfg i getting the following alert :- *[root@lxapp14012 haproxy]# haproxy -db -f /etc/haproxy/haproxy.cfg[ALERT] 040/155059 (20285) : Starting frontend haproxy_inbound: cannot bind socket [0.0.0.0:443 <http://0.0.0.0:443>]* Is it something that should be taken care of or it can be ignored??
