操作步骤

1. 以操作系统用户omm登录GaussDB 200集群任一主机。执行source ${BIGDATA_HOME}/mppdb/.mppdbgs_profile命令启动环境变量。
2. 使用“gs_om -t status --detail”命令查询集群各实例情况。

   gs_om -t status --detail

   [ Coordinator State ]
   node        node_ip         instance                                  state
   -----------------------------------------------------------------------------
   1  plat1 192.168..11  5001 /srv/BigData/mppdb/data1/coordinator Normal
   2  plat2 192.168..12  5002 /srv/BigData/mppdb/data1/coordinator Normal
   3  plat3 192.168..13  5003 /srv/BigData/mppdb/data1/coordinator Normal

   如上部署了CN实例的服务器IP地址分别为192.168.10.11、192.168.10.12和192.168.0.13。CN数据路径为“/srv/BigData/mppdb/data1/coordinator”。

3. 确认CN的端口号。

   在2查到的CN数据路径下的postgresql.conf文件中查看端口号信息。示例如下：

   cat /srv/BigData/mppdb/data1/coordinator/postgresql.conf | grep port

   port = 25308    # (change requires restart)
   #comm_sctp_port = 1024   # Assigned by installation (change requires restart)
   #comm_control_port = 10001  # Assigned by installation (change requires restart)
         # supported by the operating system:
         # e.g. 'localhost=10.145.130.2 localport=12211 remotehost=10.145.130.3 remoteport=12212, localhost=10.145.133.2 localport=12213 remotehost=10.145.133.3 remoteport=12214'
         # e.g. 'localhost=10.145.130.2 localport=12311 remotehost=10.145.130.4 remoteport=12312, localhost=10.145.133.2 localport=12313 remotehost=10.145.133.4 remoteport=12314'
         #   %r = remote host and port
   alarm_report_interval = 10
   gtm_port = 6000   # Port of GTM
   gtm_port1 = 6500   # Port1 of GTM
   pooler_port = 8001
   support_extended_features=true

   25308为CN的端口号。
