haproxy doesn't recognize mariadb service
HaProxy + IIS pages gradually get slowerHaProxy - Http and SSL pass through configHAProxy + Percona XtraDB ClusterHaproxy logging not workConnect to MariaDB through SSH fails with error 2013 - Lost connection to MySQL server at 'reading initial communication packet'HaProxy giving - 503 Service UnavailableHAProxy not logging all requestsRedis & HAProxy - updated configuration settings?SASL auth to LDAP behind HAPROXY with name mismatchesopenldap with haproxy - (ldap_result() failed: Can't contact LDAP server)
I have one haproxy server (172.24.2.42) which redirects to one mariadb server with ip 172.24.2.13.
Then I wished to replace this server with another mariadb server with ip 172.24.2.11 because this new server has more hard disk space. These servers are redhat.
I'm giving you haproxy.cfg

When I restarted haproxy service. The following message was shown:
Message from syslogd@localhost at Mar 2 19:25:59 ...
haproxy[17163]: proxy db_cluster has no server available!
Checking var/log/haproxy.log, it shows:
Mar 2 19:25:57 localhost haproxy[17158]: Server db_cluster/node-2 is DOWN, reason: Layer4 connection problem, info: "Connection refused", check duration: 0ms. 1 active and 0 backup servers left. 0 sessions active, 0 requeued, 0 remaining in queue.
Even when I'm using putty on 172.24.2.42. I do:
mysql -uuser1 -p --host=172.24.2.13 ## it logins
mysql -uuser1 -p --host=172.24.2.11 ## it logins
Even I did:
nmap 172.24.2.11
PORT STATE SERVICE
22/tcp open ssh
3306/tcp open mysql
4567/tcp open tram
Port 3306 is enabled by firewall and getenforce shows disabled
So what I do in order it works I added to haproxy.cfg:
server node-4 172.24.2.13:3306 check weight 20
Then I restarted haproxy service and mariadb 172.24.2.13 was recognized by haproxy.
Even though, that's not the idea because server 172.24.2.11 has to replace to server 172.24.2.13.
I don't know port 9200 has something to do.
What is missing?
