关于一次简单的v953节点替换的测试

953 复合节点节点替换，先替换gcware 在替换 gclusterd 最后替换 gnode

[gbase@node1 gcinstall]$ gcadmin

gcware节点替换；一次只能替换少于一半的节点
1.在可用的gcware节点 进入替换脚本目录
[gbase@node1 ~]$ cd $GCWARE_BASE
[gbase@node1 gcware]$ cd gcware_server
2.替换 192.168.111.52 的gcware
[gbase@node1 gcware_server]$ ./gcserver.py --prefix=/opt --host=192.168.111.52 --dbaUser=gbase --dbaPwd=gbase --overwrite
192.168.111.52
Are you sure to replace install these nodes ([Y,y]/[N,n])? y
Stop all gcware nodes...
UnInstall all gcware nodes...
scp gcware tar to replaced nodes...

替换gclusterd

1指令如下:
[gbase@node1 gcinstall]$ ./replace.py --host=192.168.111.52 --type=coor --dbaUser=gbase --dbaUserPwd=gbase --overwrite --generalDBUser=gbase --generalDBPwd=gbase
