Postgres-XL使用pgxc_ctl init all时出错

在单个节点上，搭建XL环境，一个GTM节点，一个Coordinator节点，两个Datanode节点。
使用pgxc_ctl配置集群节点，pgxc_ctl.conf主要配置如下：

gtmMasterServer=192.168.30.203
gtmMasterPort=20001
gtmMasterDir=$HOME/pg-xl/nodes/gtm

coordMasterDir=$HOME/pg-xl/nodes/coord
coordSlaveDir=$HOME/pg-xl/nodes/coord_slave
coordArchLogDir=$HOME/pg-xl/nodes/coord_archlog

coordNames=(coord1)             # Master and slave use the same name
coordPorts=(25432)                      # Master ports
poolerPorts=(20010)                     # Master pooler ports
coordPgHbaEntries=(192.168.30.0/24)

coordMasterServers=(192.168.30.203)             # none means this master is not available
coordMasterDirs=($coordMasterDir/coord1)
coordMaxWALsernder=0    # max_wal_senders: needed to configure slave. If zero value is specified,
                                                # it is expected to supply this parameter explicitly by external files
                                                # specified in the following.   If you dont configure slaves, leave this value to zero.
coordMaxWALSenders=($coordMaxWALsernder)
                                                # max_wal_senders configuration for each coordinator.

使用pgxc_ctl init all初始化集群，输出信息中错误如下：

ALTER NODE coord1 WITH (HOST='192.168.30.203', PORT=25432);

最开始，尝试删除XL的安装目录pg-xl，重新安装，解决过问题。但后面再碰到这个问题，重装也无效了。

请教云栖社区的PGer指点一二！谢谢！
