PXC加入新节点避免SST时grastate.dat文件内容的修改问题

在主从同步完成并关闭实例后,需要修改grastate.dat中的seqno:到底应该填已经执行过最后的XID号(Executed_Gtid_Set:),还是,还是将从哪一个执行的XID号(Executed_Gtid_Set+1)?

分析结果:从以下操作看应该为从哪一个执行的XID号(Executed_Gtid_Set+1).比如:show master status的Executed_Gtid_Set是0a15ae1e-5e2f-ee17-4638-bcd794bde339:1-3363764,那应该填:3363765
