SQL nodes in the mysql Cluster

The SQL node in the mysql cluster was tested for a week last week... Today, we are decisively back to the pace of mysql clusters. The result is still the old problem last week. When the mysql cluster environment is set up, data nodes can be connected, but SQL nodes cannot be connected. I found it online and it seems that there is a problem with the configuration. (I am looking at the tutorials provided on the Internet)

SQL node problems in mysql Clusters

I took a test last week...

Today, we are decisively back to the pace of mysql clusters.

The result is still the old problem last week.

When the mysql cluster environment is set up, data nodes can be connected, but SQL nodes cannot be connected.

I found it online and it seems that there is a problem with the configuration. (I am looking at the tutorials provided on the Internet ).

The results showed that I had a problem with the tutorial ..

During configuration, my. cnf of the data node should be configured in this way.

[Mysqld]? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ---- I used to add less here.

Datadir =/data/mysql /? ? ? ? ? ? ? ? ? ? ? ---- This is the same as that in config. ini.
