商業(yè)型greenplum貌似最近很火，小小的研究了一下

一：環(huán)境搭建

　　我使用的是單節(jié)點，用作測試，后續(xù)會有master主備模式，多臺seg節(jié)點。

?

安裝用戶：smp 安裝路徑：/home/smp/gp/ 數(shù)據(jù)目錄：/home/smp/data/d1 Master目錄：/home/smp/data/master 所有節(jié)點ip list文件：/home/smp/gp/all_hosts Agent節(jié)點文件：/home/smp/gp/seg_hosts 配置文件：/home/smp/gpinitsystem_config cp $GPHOME/docs/cli_help/gpconfigs/gpinitsystem_config /home/smp/gpinitsystem_configchmod 644 /home/smp/gpinitsystem_config對配置文件 /home/smp/gpinitsystem_config進行相應的修改

1.?編輯：?/etc/hosts

???加入所有節(jié)點ip地址，并加入??’127.0.0.1??localhost’

2.修改內(nèi)核文件/etc/sysctl.conf，追加入以下內(nèi)容：

net.ipv4.ip_forward = 0 net.ipv4.conf.default.accept_source_route = 0 kernel.sysrq = 1 kernel.core_uses_pid = 1 net.ipv4.tcp_syncookies = 1 kernel.msgmnb = 65536 kernel.msgmax = 65536 kernel.sem = 250 64000 100 512 kernel.shmmax = 500000000 kernel.shmmni = 4096 kernel.shmall = 4000000000 kernel.sem = 250 64000 100 512 net.ipv4.tcp_tw_recycle=1 net.ipv4.tcp_max_syn_backlog=4096 net.core.netdev_max_backlog=10000 vm.overcommit_memory=2

　　

3.修改最大線程數(shù)和最大打開文件數(shù)，修改文件：/etc/security/limits.conf

?

smp soft nproc 261072 smp hard nproc 131072 smp soft nofile 65536 smp hard nofile 125536

1.安裝

2.環(huán)境變量

[smp@rh1?gp]$?cat?~/.bashrc

# .bashrc# Source global definitionsif [ -f /etc/bashrc ]; then. /etc/bashrcfi# User specific aliases and functions. /home/smp/gp/greenplum_path.sh

　　

3.免密碼

?

[smp@rh1?gp]$?gpssh-exkeys??-f?all_hosts

[STEP 1 of 5] create local ID and authorize on local host... /home/smp/.ssh/id_rsa file exists ... key generation skipped[STEP 2 of 5] keyscan all hosts and update known_hosts file[STEP 3 of 5] authorize current user on remote hosts... send to 172.16.40.71[STEP 4 of 5] determine common authentication file content[STEP 5 of 5] copy authentication files to all remote hosts... finished key exchange with 172.16.40.71[INFO] completed successfully

　

4.時間同步

[smp@rh1?gp]$?gpssh?-f?seg_hosts?-v?date

[Reset ...] [INFO] login 172.16.40.71 [172.16.40.71] Thu Mar 7 00:18:38 PST 2013 [INFO] completed successfully[Cleanup...]

　

5.驗證磁盤I/O和內(nèi)存帶寬

[smp@rh1?gp]$?gpcheckperf?-f?all_hosts?-r?ds?-D?-d?/home/smp/data/d1/

/home/smp/greenplum-db/./bin/gpcheckperf?-f?all_hosts?-r?ds?-D?-d?/home/smp/data/d1/

7.查看啟動后狀態(tài)

[smp@rh1?~]$?gpstate?-s

20130307:01:56:18:015715 gpstate:rh1:smp-[INFO]:-Starting gpstate with args: -s 20130307:01:56:18:015715 gpstate:rh1:smp-[CRITICAL]:-gpstate failed. (Reason='Environment Variable MASTER_DATA_DIRECTORY not set!') exiting...

　　

有錯誤需要加入以下環(huán)境變量

?

[smp@rh1?~]$?cat?.bashrc?

　　# .bashrc# Source global definitionsif [ -f /etc/bashrc ]; then. /etc/bashrcfi# User specific aliases and functions. /home/smp/gp/greenplum_path.shMASTER_DATA_DIRECTORY=/home/smp/data/master/gpseg-1 export MASTER_DATA_DIRECTORY

然后在查看狀態(tài)，就對了

[smp@rh1?~]$?gpstate?-s

8.連接到postgres數(shù)據(jù)庫

[smp@rh1?~]$?psql?-d?postgres

　

psql (8.2.15) Type "help" for help.postgres=# select datname,datdba,encoding,datacl from pg_database;datname | datdba | encoding | datacl --------------+--------+----------+----------------------testdatabase | 10 | 6 |postgres | 10 | 6 |template1 | 10 | 6 | {=c/smp,smp=CTc/smp}template0 | 10 | 6 | {=c/smp,smp=CTc/smp}
