952版本集群修改安装目录

1、停止集群服务
  cexec all: 'gcluster_services all stop'

2、备份原配置文件
   管理节点：
     cexec coor: 'cp -r  /opt/gcluster/config /opt/gcluster/config_bak231215'
     cexec coor: 'cp -r  /opt/gcware/config /opt/gcware/config_bak231215'
      
    数据节点：
     cexec data: 'cp -r /opt/gnode/config /opt/gnode/config_bak231215'     

3、重新挂载数据盘
  mount /dev/sdb /GBase8aMPP
  
4、修改配置文件
  cexec coor: 'sed -i "s/\/opt/\/GBase8aMPP/g" /GBase8aMPP/gcware/config/gcware.conf'
  cexec coor: 'sed -i "s/\/opt/\/GBase8aMPP/g" /GBase8aMPP/gcluster/config/gbase_8a_gcluster.cnf'
  cexec coor: 'sed -i "s/\/opt/\/GBase8aMPP/g" /GBase8aMPP/gcluster/config/gcmmonit.conf'
  cexec coor: 'sed -i "s/\/opt/\/GBase8aMPP/g" /GBase8aMPP/gcluster/config/gcmonit.conf'
  cexec data: 'sed -i "s/\/opt/\/GBase8aMPP/g" /GBase8aMPP/gnode/config/gbase_8a_gbase.cnf'
  cexec data: 'sed -i "s/\/opt/\/GBase8aMPP/g" /GBase8aMPP/gnode/config/gcmmonit.conf'
  cexec data: 'sed -i "s/\/opt/\/GBase8aMPP/g" /GBase8aMPP/gnode/config/gcmonit.conf'
      

5、备份环境变量
  cexec all: 'cp /home/gbase/.gbase_profile /home/gbase/gbase_profile_bak231215'
  
6、修改环境变量
  cexec all: 'sed -i "s/\/opt/\/GBase8aMPP/g" /home/gbase/.gbase_profile'

7、重建软链接
  cexec coor: 'cd /GBase8aMPP/gcluster/server/bin;rm -f gccli;ln -s /GBase8aMPP/gcluster/server/bin/gbase gccli'
  cexec data: 'cd /GBase8aMPP/gnode/server/bin;rm -f gncli;ln -s /GBase8aMPP/gnode/server/bin/gbase gncli'
      
8、启动集群服务
