Hi, In the latest HAProxy version there is a problem to check Percona MySQL Cluster state using
clustercheck script. This problem was already described a few years ago https://github.com/olafz/percona-clustercheck/issues/2.
I decided to add 0.1sec sleep after
Connection: close response:
# Percona XtraDB Cluster node local state is 'Synced' => return HTTP 200 # Shell return-code is 0 echo -en "HTTP/1.1 200 OK\r\n" echo -en "Content-Type: text/plain\r\n" echo -en "Connection: close\r\n" sleep 0.1 echo -en "Content-Length: 40\r\n" echo -en "\r\n" echo -en "Percona XtraDB Cluster Node is synced.\r\n" sleep 0.1 exit 0
The oder way I can use tcp-check:
tcp-check connect port 9200 tcp-check send HEAD\ /\ HTTP/1.1\r\n tcp-check send \r\n tcp-check expect rstring HTTP/1\..\ (2..|3..)
Maybe you’ve a better idea?
