Postgres-XL9.5集群安装与配置

Postgres-XL9.5集群安装与配置

1、准备

1）准备主机

准备3台主机，安装centos6.2

10.1.235.19 (gtm coordinator)

10.1.235.21 (datanode)

10.1.235.22 (datanode)

在这3台机器上创建用户pgxl，将编译好的Postgres-XL9.5文件分发到3台服务器，并解压

2）配置环境变量

vi .bash_profile

exportPGHOME=/home/pgxl/pgxl9.5

export LD_LIBRARY_PATH=$PGHOME/lib:$LD_LIBRARY_PATH

export PATH=$PATH:$HOME/bin:$PGHOME/bin

source.bash_profile

3）配置ssh免密码登录

在10.1.235.19节点配置：

su - pgxl

ssh-keygen -t rsa

cat ~/.ssh/id_rsa.pub>> ~/.ssh/authorized_keys

chmod 600 ~/.ssh/authorized_keys

将刚生成的认证文件拷贝到另外2台服务器：

scp ~/.ssh/[email protected]:~/.ssh/

scp ~/.ssh/[email protected]:~/.ssh/

2、配置gtm和coordinator

1) 初始化

/home/pgxl/pgxl9.5/bin/initgtm-Z gtm -D /home/pgxl/DATA/gtm13921

/home/pgxl/pgxl9.5/bin/initgtm -Z gtm -D /home/pgxl/DATA/gtm13922

/home/pgxl/pgxl9.5/bin/initgtm-Z gtm_proxy -D /home/pgxl/DATA/gtm14921

/home/pgxl/pgxl9.5/bin/initgtm -Z gtm_proxy -D /home/pgxl/DATA/gtm14922

/home/pgxl/pgxl9.5/bin/initdb-D /home/pgxl/DATA/coord1 --nodename coord1 -E UTF8 --locale=C -U pgxl -W

/home/pgxl/pgxl9.5/bin/initdb -D /home/pgxl/DATA/coord2 --nodename coord2 -EUTF8 --locale=C -U pgxl -W

2）配置gtm

[pgxl@host-10-1-235-19 ~]$ vi /home/pgxl/DATA/gtm13921/gtm.conf

nodename = 'gtm'

listen_addresses = '*'

port = 6666

startup = ACT

3)配置coordinator

[pgxl@host-10-1-235-19 ~]$ vi /home/pgxl/DATA/coord1/postgresql.conf

# - Connection Settings -

listen_addresses = '*'

port = 11921

max_connections = 100

# DATA NODES AND CONNECTION POOLING

#----------------------------------

pooler_port = 6667 #coord2这个端口改为6668

min_pool_size = 1

max_pool_size = 100

 

# GTM CONNECTION

#--------------------------

gtm_host = '10.1.235.19'

gtm_port = 6666

pgxc_node_name = 'coord1'

 

[pgxl@host-10-1-235-19 ~]$ vi /home/pgxl/DATA/coord1/pg_hba.conf

# IPv4 local connections:

host   all            all            127.0.0.1/32         trust

host   all            all            10.1.235.0/24       trust

host   all            all            0.0.0.0/0               md5

cp /home/pgxl/DATA/coord1/pg_hba.conf /home/pgxl/DATA/coord2/

scp /home/pgxl/DATA/coord1/pg_hba.conf [email protected]:/home/pgxl/DATA/dn1/

scp /home/pgxl/DATA/coord1/pg_hba.conf [email protected]:/home/pgxl/DATA/dn2/

scp /home/pgxl/DATA/coord1/pg_hba.conf [email protected]:/home/pgxl/DATA/dn3/

scp /home/pgxl/DATA/coord1/pg_hba.conf [email protected]:/home/pgxl/DATA/dn4/

3、配置datanode（10.1.235.21 和10.1.235.22都要操作）

1) 初始化

10.1.235.21

/home/pgxl/pgxl9.5/bin/initdb-D /home/pgxl/DATA/dn1 --nodename dn1 -E UTF8 --locale=C -U pgxl -W

/home/pgxl/pgxl9.5/bin/initdb -D /home/pgxl/DATA/dn2 --nodename dn2 -E UTF8--locale=C -U pgxl -W

10.1.235.22

/home/pgxl/pgxl9.5/bin/initdb-D /home/pgxl/DATA/dn3 --nodename dn3 -E UTF8 --locale=C -U pgxl -W

/home/pgxl/pgxl9.5/bin/initdb -D /home/pgxl/DATA/dn4 --nodename dn4 -E UTF8--locale=C -U pgxl -W

2) 配置datanode

[pgxl@host-10-1-235-21 ~]$ vi /home/pgxl/DATA/dn1/postgresql.conf

CONNECTIONS AND AUTHENTICATION

#------------------------------------

listen_addresses = '*' 

port = 11921 #其他几个配置文件分别改为11922、11923、11924

max_connections = 100 

# DATA NODES AND CONNECTION POOLING

#----------------------------------------------

pooler_port = 6667 #其他几个配置文件分别改为6668、6667、6668(同一台机器要使用不同的端口)

max_pool_size = 100

 

# GTM CONNECTION

#-----------------------------

gtm_host = '10.1.235.19'

gtm_port = 6666 

pgxc_node_name = 'dn1'

4、启动

1) 启动gtm
