Greenplum Command Center 安裝部署

Greenplum Command Center介紹

Greenplum Command Center用於監控系統性能指標、分析系統健康、管理執行管理任務(如start 、stop、恢復Greenplum等)。它由data collection agent和Command Center等組件組成:

Agent:安裝在master及其他segment節點上,用於收集數據,包括查詢、系統指標等。Master節點的agent輪詢收集segment的agent數據,然後發送給Command Center Database。

Command Center Database:存放agent收集的數據和指標,然後運算後通過web界面展現。它存放在Greenplum Database的gpperfmon庫裏。

Greenplum Command Center Console:提供圖形終端用於查看系統指標和性能。

Greenplum Command Center Web Service:Greenplum Command Center Console通過web service框架來訪問Command Center 數據庫。使用的是Lighttpd服務器。

主機列表 (master節點):

cat >/workspace/gpdb/gp-all.txt <<-EOF
gpnode611.kjh.com   
gpnode612.kjh.com 
gpnode613.kjh.com   
gpnode614.kjh.com
gpnode615.kjh.com
gpnode616.kjh.com   
EOF

segment 節點

cat >/workspace/gpdb/gp-sg.txt<<-EOF
gpnode611.kjh.com   
gpnode612.kjh.com 
gpnode613.kjh.com

安裝gpcc

cd /workspace/gpdb/
wget dl.#kjh#.com/greenplum-cc-web-4.3.1-LINUX-x86_64.zip
unzip greenplum-cc-web-4.3.1-LINUX-x86_64.zip 
chown gpadmin:gpadmin -R *
su - gpadmin 

創建Command Center數據庫(gpperfmon)

運行gpperfmon_install工具,提供Greenplum Database master的端口,設置gpmon用戶密碼。

gpperfmon_install --enable --port 5432 --password gpadmin
=>]:-createdb gpperfmon >& /dev/null
=>]:-PGPORT=5432 psql -f /usr/local/greenplum-db/./lib/gpperfmon/gpperfmon.sql gpperfmon >& /dev/null

=>]:-PGPORT=5432 psql template1 -c "CREATE ROLE gpmon WITH SUPERUSER CREATEDB LOGIN ENCRYPTED PASSWORD ‘gpadmin‘"  >& /dev/null
=>]:-echo "local    gpperfmon         gpmon         md5" >> /usr/local/gpdata/gpmaster/gpseg-1/pg_hba.conf
=>]:-echo "host     all         gpmon         127.0.0.1/28    md5" >> /usr/local/gpdata/gpmaster/gpseg-1/pg_hba.conf
=>]:-echo "host     all         gpmon         ::1/128    md5" >> /usr/local/gpdata/gpmaster/gpseg-1/pg_hba.conf

=>]:-PGPORT=5432 gpconfig -c gpperfmon_log_alert_level -v warning >& /dev/null
=>]:-gpperfmon will be enabled after a full restart of GPDBbled after a full restart of GPDB

重啟Greenplum DB,重啟後data collection agent才會啟動

gpstop -r

確認 Master節點上data collection進程是否運行

ps -ef|grep gpmmon
gpadmin   33145  33135  0 14:32 ?        00:00:00 /usr/local/greenplum-db-5.10.2/bin/gpmmon -D /usr/local/gpdata/gpmaster/gpseg-1/gpperfmon/conf/gpperfmon.conf -p 5432

確認 data collection 進程已經把數據寫入到了Command Center數據庫。

如果所有segment data collection agent在運行,你可以看到segment記錄。

psql gpperfmon -c ‘SELECT * FROM system_now;‘

配置standby master

把Master上的$MASTER_DATA_DIRECTORY/pg_hba.conf文件拷貝到standby master上。確保Command Ceneter也能夠訪問standby master。拷貝Master的 ~/.pgpass文件到standby master上。
註意:.pgpass文件的權限是600。

傳輸配置文件到standby節點:
scp -rp /usr/local/gpdata/gpmaster/gpseg-1/pg_hba.conf [email protected]:/usr/local/gpdata/gpmaster/gpseg-1/
scp -rp ~/.pgpass [email protected]:~/.pgpass

重新加載配置文件 postgresql.conf 和 pg_hba.conf

gpstop -u

安裝Greenplum Command Center Console控制臺

創建數據文件夾 (以root在master執行)

source /usr/local/greenplum-db/greenplum_path.sh
gpssh -f /workspace/gpdb/gp-all.txt
=>
mkdir -p /usr/local/gpcc
chown -R gpadmin:gpadmin  /usr/local/gpcc
exit 

初始化安裝

cd /workspace/gpdb/greenplum-cc-web-4.3.1-LINUX-x86_64/  
./gpccinstall-4.3.1  
初始化過程如下:
Do you agree to the Pivotal Greenplum Command Center End User License Agreement? Yy/Nn (Default=Y)
y

Where would you like to install Greenplum Command Center? (Default=/usr/local)
 /usr/local/gpcc     《=====自定義安裝路徑          

What would you like to name this installation of Greenplum Command Center? (Default=gpcc)
What port would you like gpcc webserver to use? (Default=28080)
Would you like to enable kerberos? Yy/Nn (Default=N)
Would you like enable SSL? Yy/Nn (Default=N)

...........................

To manage Command Center, use the gpcc utility.

  gpcc [OPTIONS] <command>

Application Options:
  -v, --version   Show Greenplum Command Center version
      --settings  Print the current configuration settings

Help Options:
  -h, --help      Show this help message

  stop        Stops Greenplum Command Center webserver and metrics collection agents [-W]  option to force password prompt for GPDB user gpmon [optional] 

添加環境變量:

設置gpadmin賬戶的環境並使之生效 gpadmin賬戶操作(master,standby 節點都配置)

修改.bashrc

cat >>/home/gpadmin/.bashrc<<-EOF
GPCC_HOME=/usr/local/gpcc/greenplum-cc-web-4.3.1/

EOF
使之生效
source ~/.bashrc
source ~/.bash_profile

增加訪問權限

vim /usr/local/gpdata/gpmaster/gpseg-1/pg_hba.conf 
配置文件尾部添加內容如下:
host     all         gpmon         0.0.0.0/0    md5

傳輸配置文件到standby節點:
scp -rp /usr/local/gpdata/gpmaster/gpseg-1/pg_hba.conf [email protected]:/usr/local/gpdata/gpmaster/gpseg-1/
