I have just followed the following tutorial setting up a galera cluster. it seesmt obe working fine: https://www.digitalocean.com/community/tutorials/how-to-configure-a-galera-cluster-with-mysql-5-6-on-ubuntu-16-04
I also followed this tutorial since I want a load balancer in front of it: https://www.digitalocean.com/community/tutorials/how-to-use-haproxy-to-set-up-mysql-load-balancing–3
now, when executing the following to check if it works I always get server_id 0 returned.
mysql -h 127.0.0.1 -u haproxy_root -p -e "show variables like 'server_id'"
my config looks like this
global log 127.0.0.1 local0 notice user haproxy group haproxy defaults log global retries 2 timeout connect 3000 timeout server 5000 timeout client 5000 listen mysql-cluster bind 127.0.0.1:3306 mode tcp option mysql-check user haproxy_check balance roundrobin server galera-001 10.129.30.47:3306 check server galera-002 10.129.30.48:3306 check
When running this
mysql -h 127.0.0.1 -u haproxy_root -p -e "SHOW DATABASES"
it returns 3 tables: ±-------------------+ | Database | ±-------------------+ | information_schema | | mysql | | performance_schema | ±-------------------+
I don’t know how to fix this. anybody here has an idea?
