简介：
本文是基于greenplum5.7，greenplum-cc-web4.0安装的。
一、安装greenplum监控的数据库以及创建用户（在gpadmin用户下安装）
1、开启greenplum数据库
[gpadmin@master ~]$ gpstart -a
2、安装gpperfmon数据库，以及为gpmon用户创建密码，端口是greenplum配置的端口
[gpadmin@master ~]$ gpperfmon_install --enable --password gpmon --port 2345
3、重启数据库
[gpadmin@master ~]$ gpstop -M fast -a
[gpadmin@master ~]$ gpstart -a
4、检查gp监控是否启动
[gpadmin@master ~]$ ps -ef | grep gpmmon
5、检查gp监控是否监测到greenplum集群中的每台主机
[gpadmin@master ~]$ psql -d 'gpperfmon' -c 'select * from system_now;'
二、正式安装greenplum-cc-web（在gpadmin用户下安装）
1、创建安装目录
[gpadmin@master ~]$ gpssh -f /home/gpadmin/conf/hostlist => cd /data/greenplum-db [master1] [slave1] [slave2] [slave3] => mkdir greenplum-cc-web [master1] [slave1] [slave2] [slave3] => exit
2、解压，安装
[gpadmin@master ~]$ unzip greenplum-cc-web-4.0.0-LINUX-x86_64.zip [gpadmin@master ~]$ cd greenplum-cc-web-4.0.0-LINUX-x86_64 [gpadmin@master greenplum-cc-web-4.0.0-LINUX-x86_64]$ ./gpccinstall-4.0.0 #一直空格 I HAVE READ AND AGREE TO THE TERMS OF THE ABOVE PIVOTAL GREENPLUM DATABASE END USER LICENSE AGREEMENT. Do you agree to the Pivotal Greenplum Command Center End User License Agreement? Yy/Nn (Default=Y) Where would you like to install Greenplum Command Center? (Default=/usr/local) /opt/greenplum/greenplum-cc-web 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) Installation in progress... Successfully installed Greenplum Command Center. We recommend ssh to standby master before starting GPCC webserver To start the GPCC webserver on the current host, run gpcc start
3、修改环境变量（所有机器）
[gpadmin@master ~]$ vi .bash_profile #添加 source /opt/greenplum/greenplum-cc-web/greenplum-cc-web-4.0.0/gpcc_path.sh [gpadmin@master ~]$ source .bash_profile
4、修改pg_hba.conf文件连接
[gpadmin@master ~]$ vi /data/greenplum-db/gpdata/gpmaster/gpseg-1/pg_hba.conf #在最后一行添加这句 host all gpmon （本机的ip）/24 md5 [gpadmin@master ~]$ gpstop -M fast -a [gpadmin@master ~]$ gpstart -a [gpadmin@master ~]$ gpcc start
三、登录访问
1、打开网址访问http://192.168.12.101:28080/login，密码为前面设置的密码
2、常用gpcc命令
gpcc stop
gpcc start
