GBase 8a集群节点的端口修改方法：
Gcluster端口5258可以更改，在集群的所有节点上进行如下操作：
1、使用dbauser用户修改$GCLUSTER_BASE/config/gbase_8a_gcluster.cnf文件中相关内容，具体修改参数如下：

[client]

port=5258

socket=/tmp/gcluster_5258.sock

[gbased]

socket=/tmp/gcluster_5258.sock

port=5258

2、需要将5258修改为新的端口号，具体如下：

su - gbase

$ vi $GCLUSTER_BASE /config/gbase_8a_gcluster.cnf

[client]

port=5259

socket=/tmp/gcluster_5259.sock

…

[gbased]

…

socket=/tmp/gcluster_5259.sock

…

port=5259

…

3、各个节点上的配置文件修改后，重新启动gcware服务。

su - gbase

$ su - root

密码：

gcluster_service gcware restart

Signaling GCMETARECOVER (gcmetarecover) to terminate: [ OK ]

Waiting for gcmetarecover services to unload:[ OK ]

Signaling GCDATARECOVER (gcdatarecover) to terminate: [ OK ]

Waiting for gcdatarecover services to unload:[ OK ]

Signaling GCSYNC (gc_sync_server) to terminate: [ OK ]

Waiting for gc_sync_server services to unload:[ OK ]

Signaling GCLUSTERD to terminate: [ OK ]

Waiting for gclusterd services to unload:…[ OK ]

Signaling GBASED to terminate: [ OK ]

Waiting for gbased services to unload:.[ OK ]

Signaling GCWARE (gcware) to terminate: [ OK ]

Waiting for gcware services to unload:[ OK ]

Starting GCWARE (gcwexec): [ OK ]

Starting GBASED : [ OK ]

Starting GCLUSTERD : [ OK ]

Starting GCSYNC : [ OK ]

Starting GCMETARECOVER : [ OK ]

Starting GCDATARECOVER : [ OK ]

4、使用root用户，验证新端口设置成功。

$ su - root

密码：

lsof -i:5259

COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME

gclusterd 4780 gbase 14u IPv4 23640 0t0 TCP *:5259 (LISTEN)

Gnode端口5050可以更改 ，在集群的所有节点上进行如下操作：
1、 使用dbauser用户修改$GCLUSTER_BASE/config/gbase_8a_gcluster.cnf文件中相关内容，具体修改的参数如下：

[gbased]

…

gcluster_gnode_port = 5050

2、下面需要将5050修改为新的端口号，具体如下；

su - gbase

$ vi $GCLUSTER_BASE /config/gbase_8a_gcluster.cnf

[gbased]

…

gcluster_gnode_port = 5051

…

3、使用gbase用户修改$GCLUSTER_BASE/config/gbase_8a_gbase.cnf文件中相关内容，具体修改的参数如下：

[client]

port=5050

socket=/tmp/gbase_8a_5050.sock

[gbased]

…

socket=/tmp/gbase_8a_5050.sock

…

port=5050

…

4、下面需要将5050修改为新的端口号，具体如下；

su - gbase

$ vi /opt/gnode/config/gbase_8a_gbase.cnf

[client]

port=5051

socket=/tmp/gbase_8a_5051.sock

[gbased]

…

socket=/tmp/gbase_8a_5051.sock

…

port=5051

…

5、 各个节点上的配置文件修改后，重新启动gcware服务。

$ su - root

密码：

gcluster_service gcware restart

Signaling GCMETARECOVER (gcmetarecover) to terminate: [ OK ]

Waiting for gcmetarecover services to unload:[ OK ]

Signaling GCDATARECOVER (gcdatarecover) to terminate: [ OK ]

Waiting for gcdatarecover services to unload:[ OK ]

Signaling GCSYNC (gc_sync_server) to terminate: [ OK ]

Waiting for gc_sync_server services to unload:[ OK ]

Signaling GCLUSTERD to terminate: [ OK ]

Waiting for gclusterd services to unload:…[ OK ]

Signaling GBASED to terminate: [ OK ]

Waiting for gbased services to unload:.[ OK ]

Signaling GCWARE (gcware) to terminate: [ OK ]

Waiting for gcware services to unload:[ OK ]

Starting GCWARE (gcwexec): [ OK ]

Starting GBASED : [ OK ]

Starting GCLUSTERD : [ OK ]

Starting GCSYNC : [ OK ]

Starting GCMETARECOVER : [ OK ]

Starting GCDATARECOVER : [ OK ]

6、使用root用户，验证新端口设置成功。

$ su - root

密码：

lsof -i:5051

COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME

gbased 3452 gbase 5u IPv4 17730 0t0 TCP *:ita-agent
(LISTEN)

syncserver端口5288可以更改，在集群的所有节点上进行如下操作：

1.   使用gbase用户在/opt/gnode/config下修改synctool.conf文件
   1

2.   在synctool.conf增加如下内容：
   1

su - gbase

$ cd /opt/gnode/config/

$ vi synctool.conf

SERVER_PORT=5288

LOG_LEVEL=3

BLOCK_SIZE=512

说明：

• SERVER_PORT是端口号，默认5288，在此填写指定的端口；
• LOG_LEVEL 是log级别，取值0，1，2，3，4分别代表ERROR，WARNING，INTERFACE，INFO，DEBUG；
• 同步工具进行网络传输的数据块大小上限；

3、修改完后，在各个节点机器中，使用root用户，重新启动gcware服务生效。

$ su - root

密码：

gcluster_service gcware restart

Signaling GCMETARECOVER (gcmetarecover) to terminate: [ OK ]

Waiting for gcmetarecover services to unload:[ OK ]

Signaling GCDATARECOVER (gcdatarecover) to terminate: [ OK ]

Waiting for gcdatarecover services to unload:[ OK ]

Signaling GCSYNC (gc_sync_server) to terminate: [ OK ]

Waiting for gc_sync_server services to unload:[ OK ]

Signaling GCLUSTERD to terminate: [ OK ]

Waiting for gclusterd services to unload:…[ OK ]

Signaling GBASED to terminate: [ OK ]

Waiting for gbased services to unload:.[ OK ]

Signaling GCWARE (gcware) to terminate: [ OK ]

Waiting for gcware services to unload:[ OK ]

Starting GCWARE (gcwexec): [ OK ]

Starting GBASED : [ OK ]

Starting GCLUSTERD : [ OK ]

Starting GCSYNC : [ OK ]

Starting GCMETARECOVER : [ OK ]

Starting GCDATARECOVER : [ OK ]

4、使用root用户，验证新端口是否设置成功。

lsof -i:5287

COMMAND PID USER FD TYPE DEVICE SIZE/OFF NODE NAME

gc_sync_s 3876 gbase 4u IPv4 20103 0t0 TCP *:5287 (LISTEN)
