GBase 8c 确认数据库连接

客户端工具通过数据库主节点连接数据库。因此连接前，需获取数据库主节点所在服务器的IP地址及数据库主节点的端口号信息。

操作步骤

步骤1 以操作系统用户gbase登录数据库主节点。

步骤2 使用“gs_om -t status --detail”命令查询GBase 8c各实例情况。

$ gs_om -t status --detail

 [   Cluster State   ]



cluster_state   : Normal

redistributing  : No

current_az      : AZ_ALL



[  Datanode State   ]



    node       node_ip         port      instance                                           state

-----------------------------------------------------------------------------------------------------------------

1  gbase8c_7_6  host_ip        5600       6001 /home/gbase/clusters/gbase8c/datanode/dn_1   P Primary Normal

如上部署了数据库主节点实例的服务器IP地址分别为host_ip。数据库主节点数据路径为/home/gbase/clusters/gbase8c/datanode/dn_1。“P”表示安装时指定的角色为Primary，数据库安装后不在变化，从系统静态文件读取；“Primary”表示实例为主实例； “Normal”表示GBase 8c可用，且数据有冗余备份，所有进程都在运行，主备关系正常。

步骤3 确认数据库主节点的端口号。

在步骤2查到的数据库主节点数据路径下的postgresql.conf文件中查看端口号信息。示  例如下：

cat /home/gbase/clusters/gbase8c/datanode/dn_1/postgresql.conf | grep port

port = 5600                             # (change requires restart)

#ssl_renegotiation_limit = 0            # amount of data between renegotiations, no longer supported

                                        # supported by the operating system:

                                                # The heartbeat thread will not start if not set localheartbeatport and remoteheartbeatport.

                                                # e.g. 'localhost=10.145.130.2 localport=12211 localheartbeatport=12214 remotehost=10.145.130.3 remoteport=12212 remoteheartbeatport=12215, localhost=10.145.133.2 localport=12213 remotehost=10.145.133.3 remoteport=12214'

                                        #   %r = remote host and port

alarm_report_interval = 10

5600为数据库主节点的端口号。
