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

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！
