thanks for your help. I failed to build a Postgres-XL cluster. My gtm.confg :
listen_addresses = '0.0.0.0'
port = 6668
at 10.80.19.47. My gtm_proxy.confg:
listen_addresses = '0.0.0.0'
port = 6666
gtm_host = '10.80.19.47'
gtm_port = 6668
after start gtm and gtm_proxy ,i show net information use lsof -i :
gtm 11730 postgres 6u IPv4 355914 0t0 TCP 10.80.19.47:ircu-4->10.80.19.46:44017 (ESTABLISHED
gtm 11730 postgres 7u IPv4 355915 0t0 TCP 10.80.19.47:ircu-4->10.80.19.46:44018 (ESTABLISHED)
gtm 11730 postgres 8u IPv4 355916 0t0 TCP 10.80.19.47:ircu-4->10.80.19.46:44019 (ESTABLISHED)
Then i configure datanode like:
listen_addresses = '0.0.0.0'
port = 5432
pooler_port = 20002
gtm_host = '127.0.0.1'
gtm_port = 6666
and coordinator like:
listen_addresses = '0.0.0.0'
port = 3456
pooler_port = 20003
gtm_host = '127.0.0.1'
gtm_port = 6666
others are default ,then i start datanode with :
/usr/postgres-xl-9.2/bin/postgres --datanode -D /data1/pgsql/data &
start coordinator with:
/usr/postgres-xl-9.2/bin/postgres --coordinator -D /data1/pgsql/coordinator &
when i connect to Postgres-XL use coordinator with :
psql -h 127.0.0.1 -p 3456 postgres;
when i want to create a database with:
create database test;
but failed,it shows :
No Datanode defined in cluster
You need to define at least 1 Datanode with CREATE NODE.
then i check the cluster with :
psql -h 127.0.0.1 -p 3456 postgres -c "select * from pgxc_node order by 1";
it shows just one node like:
node_name | node_type | node_port | node_host | nodeis_primary | nodeis_preferred | node_id
-------------------+-----------+-----------+-----------+----------------+------------------+-----------
coordinator_node2 | C | 5432 | localhost | f | f | 738118815
and i connect to port 5432 it shows the similar information like:
node_name | node_type | node_port | node_host | nodeis_primary | nodeis_preferred | node_id
------------+-----------+-----------+-----------+----------------+------------------+------------
data_node2 | C | 5432 | localhost | f | f | -923817565
what wrong with my Configuration? Thanks all.
You need to define datanode something like this.
./psql -c "CREATE NODE datanode1 WITH (TYPE = 'datanode', PORT = 7777)" postgres -p 3456 -h 127.0.0.1
