Installing and enabling Greenplum Command Center
Installation GreenPlum Performance Monitor
GreenPlum安装性能监控工具GPCCC（Greenplum Command Center Console）
1>、前期准备：
a. 创建greenplum监控用数据库(gpperfmon)
b. 创建greenplum监控用数据库角色(gpmon)
c. 配置greenplum数据库接受来自perfmon监控的链接文件(pg_hba.conf和.pgpass)
d. 设置postgresql.conf文件，增加启用监控的参数。（这些参数默认会添加在文件的末尾）
gp_enable_gpperfmon=on
gpperfmon_port=8888
gp_external_enable_exec=on
gpperfmon_log_alert_level=warning
e. 设置pg_hba.conf文件，增加如下信息：
local gpperfmon gpmon md5
host all gpmon 127.0.0.1/28 md5
安装依赖
yum install vixie-cron -y # 若 gpcc要安装 workload manaager，需要安装这个
安装gpperfmon

[gpadmin@dbaone ~]$ gpcmdr --setup
An instance name is used by the Greenplum Command Center as
a way to uniquely identify a Greenplum Database that has the monitoring
components installed and configured. This name is also used to control
specific instances of the Greenplum Command Center web UI. Instance names
can contain letters, digits and underscores and are not case sensitive.
Please enter a new instance name:
> Mr_Liu_gp
The web component of the Greenplum Command Center can connect to a
monitor database on a remote Greenplum Database.
Is the master host for the Greenplum Database remote? Yy|Nn (default=N):
>
The display name is shown in the web interface and does not need to be a hostname.
What would you like to use for the display name for this instance:
> greenplum_test
What port does the Greenplum Database use? (default=5432):
>
Creating instance schema in GPDB. Please wait ...
The display name is shown in the web interface and does not need to bea hostname.
Would you like to install workload manager? Yy|Nn (default=N): ## 若与master不在一台机器上，是不能选择y的。
>
Skipping installation of workload manager.
The Greenplum Command Center runs a small web server for the UI and web API.
This web server by default runs on port 28080, but you may specify any available port.
What port would you like the web server to use for this instance? (default=28080):
>
Users logging in to the Command Center must provide database user
credentials. In order to protect user names and passwords, it is recommended
that SSL be enabled.
Do you want to enable SSL for the Web API Yy|Nn (default=N):
>
Do you want to enable ipV6 for the Web API Yy|Nn (default=N):
>
Do you want to enable Cross Site Request Forgery Protection for the Web API Yy|Nn (default=N):
>
Do you want to copy the instance to a standby master host Yy|Nn (default=Y):
>
What is the hostname of the standby master host? [smdw]: dbafour
standby is dbafour
