【Greenplum 6.9.0】Greenplum Command Center 6.2安装失败教程

需要这个？

gpperfmon_install --enable --password gpmon --port 5432

-bash: gpperfmon_install: command not found

直接安装？

unzip gpcc.zip

报错

Failed to connect to database postgres on 127.0.0.1:5432 as gpadmin: libgssapi_krb5.so: cannot open shared object file: No such file or director

Failed to connect to database postgres on 127.0.0.1:5432 as gpadmin???
psql命令能进啊，为什么这里不能连？

libgssapi_krb5.so这是啥？No such file

百度搜libgssapi_krb5.so
缺少东西，需要安装

yum install krb5-libs

安装了没效果！

找到/usr/lib64里的同名文件

名字不一样啊，复制一个改名叫libgssapi_krb5.so试试

终于，开始安装

./gpccinstall-6.2.0

报错

gpmon不能连上数据库！密码验证失败

修改pg_hba.conf
给gpmon trust，保证他能连上

local       all           gpmon  127.0.0.1/28   trust
host       all           gpmon  127.0.0.1/28   md5
host       all           gpmon  ::1/128        md5
host       all           gpmon  samenet        md5

命令行/navicat进入数据库gpperfmon，修改gpmon密码

ALTER ROLE gpmon WITH ENCRYPTED PASSWORD 'gpmon';

重新安装

./gpccinstall-6.2.0 -W

密码gpmon，这次能成功了

启动

在/tmp/下找到gpcc文件夹

source gpcc_path.shgpcc start -W
gpcc stop //停止

http://xxx.xx.x.x.:28080/

看到有error，明天再解决，下班了。agent没有启动

[gpadmin@site92 /]$ gpcc status

需要安装metrics_collector扩展

error

[gpadmin@site92 gppkg]$ psql gpperfmon -c 'create extension metrics_collector'
ERROR:  extension can only be created when shared_preload_libraries contains metrics_collector

设置shared_preload_libraries=metrics_collector
需要重启gp

哦豁，集群启不动了

这个错误我原来不知道是咋造成的，启动log里面没有error，只有正常的info.没办法，找不到错误在哪，就重新初始化集群了。重新初始化，安装gpcc，当我修改了pg_hba.conf后，错误重现了，可是我格式没问题啊，而且删了之后，还是报错。又重现初始化，反复几次，我决定不安装这个垃圾GPCC了，垃圾玩意！
