【中文标题】无法在 Centos 7 集群的 Greenplum 开源数据库上设置 Greenplum 命令中心 Web 应用程序的实例

【英文标题】：Cannot Setup Instance of Greenplum Command Center Web Application on Greenplum Open Source Database with Centos 7 Cluster

【问题描述】：

我在 3 节点 Centos 7 集群上运行了 Greenplum 开源数据库。数据库正在运行，我能够连接并运行查询。 Greenplum Command Center 2.0 的安装工作。当我尝试使用

为 Web 设备部件配置实例时

gpcmdr --setup

我收到以下错误：

Creating instance schema in GPDB.  Please wait ...
Failed to setup Command Center instance [myCustomInstance]: 
Exception encountered while fetching GPDB version info Connection error for query select version();: 
FATAL:  Ident authentication failed for user "gpmon"

这是我用于测试目的的 pg_hba.conf 文件。即使使用 host all all ::1/128 trust

，这仍然会产生上述错误

# IPv6 local connections:
local    all         gpadmin         ident
host     all         gpadmin         127.0.0.1/28    trust
host     all         gpadmin         172.17.0.1/32       trust

host     all         gpadmin         fe80::b84c:8bff:fe4a:5ce2/128       trust
host     all         gpadmin         fe80::419:d7ff:fe90:6c48/128       trust
host     all         gpadmin         fe80::c0ff:81ff:feae:c1ec/128       trust
local    replication gpadmin         ident
host     replication gpadmin         samenet       trust
local    gpperfmon         gpmon         md5
host     all         gpmon         0.0.0.0/0    md5
host all gpmon ::1/128 md5    
host all all ::1/128 trust

在最后一行之前的 host all gpmon ::1/128 md5 中添加。重新启动数据库并重新运行 gpcmdr --setup。以下是日志文件

【问题讨论】：

尝试在最后一行前添加host all gpmon ::1/128 md5

还要检查 GPDB 数据库日志中的错误消息并更新添加它的问题

【参考方案1】：

好像gp_toolkit.__gp_log_master_ext 不存在。该表是在 gpdb 生成其架构时创建的。请你试试 "\d gp_toolkit.__gp_log_master_ext"在gpdb中看看表是否规范化了？
