1. System requirement

CentOS 7.2 X64

Postgres-xl-9.5r1.4.tar.gz

# yum install-y gcc-c++

# yum install-y readline-devel

# yum install-y zlib-devel

# yum install-y perl

# yum install-y flex

# yum install-y flex-devel

two。 Install postgres-xl

/ home/soft/

Tar zxvf postgres-xl-9.5r1.4.tar.gz

. / configure

Make

Make install

3. Add user

Adduser postgres

Su-postgres

Vi .bash _ profile

Export LD_LIBRARY_PATH=/usr/local/pgsql/lib

Export PATH=/usr/local/pgsql/bin:$PATH

Export MANPATH=/usr/local/pgsql/share/man:$MANPATH

4. Set up a data directory

-- create data directories for coord, datanode and gtm

Mkdir-p / opt/pgxl/data/data_coord1

Mkdir-p / opt/pgxl/data/data_datanode_1

Mkdir-p / opt/pgxl/data/data_datanode_2

Mkdir-p / opt/pgxl/data/data_gtm

Chown postgres / opt/pgxl/data/data_coord1

Chown postgres / opt/pgxl/data/data_datanode_1

Chown postgres / opt/pgxl/data/data_datanode_2

Chown postgres / opt/pgxl/data/data_gtm

5. Initialize coordinator, datanode

Su-postgres

/ usr/local/pgsql/bin/initdb-D / opt/pgxl/data/data_coord1\

-- nodename coord1

/ usr/local/pgsql/bin/initdb-D / opt/pgxl/data/data_datanode_1\

-- nodename datanode_1

/ usr/local/pgsql/bin/initdb-D / opt/pgxl/data/data_datanode_2\

-- nodename datanode_2

/ usr/local/pgsql/bin/initgtm-D / opt/pgxl/data/data_gtm-Z gtm

6. Start gtm, datanode, coordinator

-- gtm

/ usr/local/pgsql/bin/gtm-D / opt/pgxl/data/data_gtm > / opt/pgxl/data/data_gtm/gtm_logfile.log 2 > & 1 &

-- datanode

/ usr/local/pgsql/bin/postgres-- datanode-p 15432-c pooler_port=40101\

-D / opt/pgxl/data/data_datanode_1 > / opt/pgxl/data/data_datanode_1/datanode1_logfile.log 2 > & 1 &

/ usr/local/pgsql/bin/postgres-- datanode-p 15433-c pooler_port=40102\

-D / opt/pgxl/data/data_datanode_2 > / opt/pgxl/data/data_datanode_1/datanode2_logfile.log 2 > & 1 &

-- coordinator

/ usr/local/pgsql/bin/postgres-- coordinator-c pooler_port=40100\

-D / opt/pgxl/data/data_coord1 > / opt/pgxl/data/data_coord1/data_coord1_logfile.log 2 > & 1 &

7. Configure node type, port

/ usr/local/pgsql/bin/psql-c "ALTER NODE coord1\

WITH (TYPE = 'coordinator', PORT = 5432) "postgres

/ usr/local/pgsql/bin/psql-c "CREATE NODE datanode_1\

WITH (TYPE = 'datanode', PORT = 15432) "postgres

/ usr/local/pgsql/bin/psql-c "CREATE NODE datanode_2\

WITH (TYPE = 'datanode', PORT = 15433) "postgres

8. Configuration execution orientation

/ usr/local/pgsql/bin/psql-c "EXECUTE DIRECT ON (datanode_1)\

'ALTER NODE datanode_1 WITH (TYPE =''datanode'', PORT = 15432)' "postgres

/ usr/local/pgsql/bin/psql-c "EXECUTE DIRECT ON (datanode_1)\

'CREATE NODE datanode_2 WITH (TYPE =''datanode'', PORT = 15433)' "postgres

/ usr/local/pgsql/bin/psql-c "EXECUTE DIRECT ON (datanode_1)\

'CREATE NODE coord1 WITH (TYPE =''coordinator'', PORT = 5432)' "postgres

/ usr/local/pgsql/bin/psql-c "EXECUTE DIRECT ON (datanode_2)\

'ALTER NODE datanode_2 WITH (TYPE =''datanode'', PORT = 15433)' "postgres

/ usr/local/pgsql/bin/psql-c "EXECUTE DIRECT ON (datanode_2)\

'CREATE NODE datanode_1 WITH (TYPE =''datanode'', PORT = 15432)' "postgres

/ usr/local/pgsql/bin/psql-c "EXECUTE DIRECT ON (datanode_2)\

'CREATE NODE coord1 WITH (TYPE =''coordinator'', PORT = 5432)' "postgres

9. Overload configuration

/ usr/local/pgsql/bin/psql-c "SELECT pgxc_pool_reload ()" postgres

/ usr/local/pgsql/bin/psql-c "EXECUTE DIRECT ON (datanode_1)\

'SELECT pgxc_pool_reload ()' "postgres

/ usr/local/pgsql/bin/psql-c "EXECUTE DIRECT ON (datanode_2)\

'SELECT pgxc_pool_reload ()' "postgres

10. Insertion test

Create a test table

Log in to coordinator

/ usr/local/pgsql/bin/createdb test

/ usr/local/pgsql/bin/psql test

Test=# create table T1 (id int, name varchar (20))

Test=#\ dt

List of relations

Schema | Name | Type | Owner

-+-

Public | T1 | table | postgres

(1 row)

Test=# insert into T1 SELECT generate_series (1) as key, 'Peter' | | (random () * (10 ^ 3)):: integer

INSERT 0 1000000

Test=#\ timing

Timing is on.

Test=# insert into T1 SELECT generate_series (1000001Power5000000) as key, 'Peter' | | (random () * (10 ^ 3)):: integer

INSERT 0 4000000
