GBase8a 集群 V953 版本修改IP地址脚本。

1、本脚本适用于V953集群修改IP地址，本来用于ZH项目集群搬迁。

     ZH项目计划采用移动硬盘方式进行集群搬迁，即将原集群数据备份至移动硬盘，在新的集群节点进行恢复，随后修改IP恢复集群服务。

     故此脚本依赖集群列表配置文件(server_restore.lst)，该文件记录个节点的角色（coor、data 或 所属vc），节点编号、以及新旧节点对应关系。

     该脚本也可独立运行，可手工编写该配置文件，配置文件格式参考如下：

#cluster_name node_type sync_type node_no  old_ip  source_path   target_path  new_ip  
kane	coor	local	c1	192.168.59.41	data	/opt	192.168.59.141
kane	coor	local	c2	192.168.59.42	data	/opt	192.168.59.142
kane	coor	local	c3	192.168.59.43	data	/opt	192.168.59.143
kane	vc1	local	d1	192.168.59.43	data	/opt	192.168.59.143
kane	vc1	local	d2	192.168.59.53	data1	/opt	192.168.59.153
kane	vc1	local	d3	192.168.59.44	data	/opt	192.168.59.144
kane	vc1	local	d4	192.168.59.54	data1	/opt	192.168.59.154
kane	vc2	local	d1	192.168.59.41	data	/opt	192.168.59.141
kane	vc2	local	d2	192.168.59.51	data1	/opt	192.168.59.151
kane	vc2	local	d3	192.168.59.42	data	/opt	192.168.59.142
kane	vc2	local	d4	192.168.59.52	data1	/opt	192.168.59.152
kane	vc3	local	d1	192.168.59.45	data	/opt	192.168.59.145
kane	vc3	local	d2	192.168.59.55	data1	/opt	192.168.59.155

2、修改之前要求已经刷新过gcware快照。

3、脚本依赖节点之间互信，请确认已配置完毕gbase用户互信。

4、修改步骤：

     4.1、 先根据配置文件，生成新旧IP地址对应的nodeid；

     4.2、按照节点类型，生成针对每个节点的修改脚本；

     4.3、将脚本推送至相应节点，执行修改操作；

     4.4、修改完成后即可启动集群。

完整脚本代码如下：

#!/bin/bash
