Greenplum database is the official gpcc own database monitoring software.
This article will explain in detail the process gpcc installation, the installation of a relatively new version 4.5.1
Installation configuration GPCC Monitoring Software
1. Open the data collection agent (Data Collection Agents, DCA)
1.1 gpperfmon_install tools to complete the task
gpperfmon_install tools to complete tasks include:
1. Create a command center (CC) database, gpperfmon
2. Create a CC Super User, gpmon
3. Configure CC to connect GPDB by editing pg_hba.conf file and .pgpass
4. Set the parameter CC in GPDB by editing postgresql.conf
2. Open the data collection agent (Data Collection Agents, DCA)
Open Data collection agency steps:
1) Log gpadmin:
are - gpadmin
2) In the master host environment variable source gp
source /usr/local/greenplum-db/greenplum_path.sh
3) Run gpperfmon_install tool, create a database gpperfmon
$ gpperfmon_install --enable --password gpcc1234 --port 5432
This step is to create a super user gpmon, -password login password is set, this setting is gpcc1234
4) Restart GPDB, the effect:
Shut down the database:
$ gpstop -M fast
Restart the database:
gpstart -a
5) Check the master host DCA process: $ ps -ef | grep gpmmon
6) Verify DCA writable GPCC database, if all segment of DCA normal, you can see by following command,
$ psql gpperfmon -c 'SELECT * FROM system_now;'
In addition, if there is standby, you need to configure:
- Copy $ MASTER_DATA_DIRECTORY / pg_hba.conf to respective standby positions
- Copy ~ / .pgpass position corresponding to standby; chmod 0600 ~ / .pgpass
3. Install GPCC monitoring software (Greenplum Command Center Console)
1) Download, unzip software
unzip greenplum-cc-web-4.5.1-LINUX-x86_64.zip /data/backup/
2) Configuration gpcc.conf
Gpcc initialization file when you need to configure gpcc.conf
The gpcc.conf gpcc software files into a directory, namely / data / backup /
The contents of the configuration file is as follows:
path= /data/gpcc
master_port=5432
web_port = 28080
rpc_port=8899
enable_ssl=false
enable_kerberos=false
Upload files to gpcc bin directory and modify the file owner:
chown -R gpadmin:gpadmin gpcc.conf
3) create / data / gpcc directory gp each cluster node, and belong to the group is gpadmin: gpadmin
mkdir -p /data/gpcc;
chown -R gpadmin:gpadmin /data/gpcc;
4) Log gpadmin, installation
cd /data/backup/greenplum-cc-web-4.5.1-LINUX-x86_64;
$ ./gpccinstall-4.5.1 -c gpcc.conf
5) Set gpadmin environment variables
$ source /usr/local/greenplum-db/greenplum_path.sh
$ source /data/gpcc/greenplum-cc-web-4.5.1/gpcc_path.sh
6) Set gpadmin environment variable, ~ / .bashrc or ~ / .bash_profile
GPPERFMONHOME=/data/gpcc/greenplum-cc-web-4.5.1
source $GPPERFMONHOME/gpcc_path.sh
7) Start CC instance
gpcc start
8) Log GP CCC
https://master_host_name:28080/
My masterIP address is 192.168.178.130, and therefore
gpcc Address:
Login: gpmon
Password: gpcc1234
