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/authorized_keyspgxl@10.1.235.21:~/.ssh/
scp ~/.ssh/authorized_keyspgxl@10.1.235.22:~/.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 pgxl@10.1.235.21:/home/pgxl/DATA/dn1/
scp /home/pgxl/DATA/coord1/pg_hba.conf pgxl@10.1.235.21:/home/pgxl/DATA/dn2/
scp /home/pgxl/DATA/coord1/pg_hba.conf pgxl@10.1.235.22:/home/pgxl/DATA/dn3/
scp /home/pgxl/DATA/coord1/pg_hba.conf pgxl@10.1.235.22:/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
