GBase8a如何修改IP地址

IP地址修改操作步骤（V952版本测试通过）：

1. 计算nodeid

    原IP地址：192.168.92.129    新IP地址：192.168.92.151
    GBASE> SELECT '192.168.92.151' AS IPAddr,
                INET_ATON('151.92.168.192') AS NodeID, 
                CAST(INET_ATON('151.92.168.192') AS INT) - 4294967296 AS minus_NodeID
            FROM DUAL;
    +----------------+------------+--------------+
    | IPAddr         | NodeID     | minus_NodeID |
    +----------------+------------+--------------+
    | 192.168.92.151 | 2539432128 |  -1755535168 |
    +----------------+------------+--------------+

    
2. 停服务
    gcluster_services all stop

3. 启动gcware
    gcware_services gcware start

4. 刷快照
    python
    >>> import gcware
    >>> gcware.flush_statemachine()    #重复至max(REDO.n)-1=max(SNAPSHOT.xx.n+1)
    
5. 停止gcware
    gcware_services gcware stop

6. 修改操作系统IP地址
    vi /etc/sysconfig/network-scripts/ifcfg-ens32

7. 修改集群IP

8. 启动服务
    gcluster_services all start

9. 验证
    gcadmin

10. 问题总结
    问题：gcadmin显示集群状态正常，gccli -e"show nodes" 有节点OFFLINE，查询表提示：Failed to get metadata ... no valid nodes ....
    解决: 多执行几次：gcluster_services all restart，更新gcluster缓存即可。
