MySQL PXC添加新节点只需IST传输的方法
PXC传输数据有两种方式：
IST: Incremental State Transfer 增量同步
SST：State Snapshot Transfer 全量同步
IST 发生的条件：This is done using caching mechanism on nodes （即只发生在之前集群里的节点数据还有在缓存中）
判断方法：
在主节点上
mysql> show global status like 'wsrep_local_cached_downto';
+---------------------------+-------+
| Variable_name | Value |
+---------------------------+-------+
| wsrep_local_cached_downto | 1 |
+---------------------------+-------+
1 row in set (0.00 sec)
此值小于新添加节点的seqno：
[root@mysql2 data]# cat grastate.dat
# GALERA saved state
version: 2.1
uuid: 6a244048-3a0e-11e6-9016-831e882dea43
seqno: 16
cert_index:
即通过备份，将新节点先做成slave，并伪造一个grastate.dat，来记录新节点数据的seqno,这样当新节点启动时就会自动用IST的方法来进行，而不是SST（注意gcache.size应该有足够的容量来保证在备份及恢复这段时间内新产生的数据都被缓存到）
搭建pxc环境，请看http://blog.csdn.net/zhanglei_16/article/details/51473538
如下为这次的操作步骤：
mysql1：192.168.1.41 --已经存在的集群节点
mysql2：192.168.1.42 --将要加入的集群节点
1：启动mysql1，使用xtrabackup备份mysql1，并在mysql2上恢复

找出Xid的位置：
方法一：查看文件xtrabackup_galera_info
[root@mysql2 2016-06-25_21-30-21]# cat xtrabackup_galera_info
6a244048-3a0e-11e6-9016-831e882dea43:16
方法二：通过binlog位置来查找
[root@mysql2 2016-06-25_21-30-21]# cat xtrabackup_binlog_info
mysql-bin.000002 120
即备份时的备份点位置为log_bin.000002 120
再去Mysql1查找此binlog对应的xid：
[root@mysql1 bin]# cd /mysql/logs/
[root@mysql1 logs]# /usr/local/mysql/bin/mysqlbinlog -vv mysql-bin.000002 |grep Xid
#160625 21:34:40 server id 213306 end_log_pos 317 CRC32 0xa3386f6d Xid = 17
由于120是每个binlog开始的pos位，把Xid设为16.
在Mysql2上伪造一个grastate.dat文件（从Mysql1上复制过来，更改下seqno即可）：
[root@mysql2 data]# cat grastate.dat
# GALERA saved state

成功用IST来恢复了。
可以拿这里的error.log，与正常添加节点的error.log，进行比较，这里省略。
登录mysql2，查看数据是否正常：

发现数据也已经全部同步完成。
pxc环境下避免新节点加入时需要进行SST的方法，在数据量大时SST将会占用大量的资源，
配置的gcache.size足够容纳从备份到恢复此时间段内主节点产生的数据量，建议通过业务
低峰期时通过脚本来实现此新节点加入操作。
参考文档：http://www.cnblogs.com/zejin2008/p/5537174.html
PXC传输数据有两种方式：
IST: Incremental State Transfer 增量同步
SST：State Snapshot Transfer 全量同步
IST 发生的条件：This is done using caching mechanism on nodes （即只发生在之前集群里的节点数据还有在缓存中）
判断方法：
在主节点上
mysql> show global status like 'wsrep_local_cached_downto';
+---------------------------+-------+
| Variable_name | Value |
+---------------------------+-------+
| wsrep_local_cached_downto | 1 |
+---------------------------+-------+
1 row in set (0.00 sec)
此值小于新添加节点的seqno：
[root@mysql2 data]# cat grastate.dat
# GALERA saved state
version: 2.1
uuid: 6a244048-3a0e-11e6-9016-831e882dea43
seqno: 16
cert_index:
即通过备份，将新节点先做成slave，并伪造一个grastate.dat，来记录新节点数据的seqno,这样当新节点启动时就会自动用IST的方法来进行，而不是SST（注意gcache.size应该有足够的容量来保证在备份及恢复这段时间内新产生的数据都被缓存到）
搭建pxc环境，请看http://blog.csdn.net/zhanglei_16/article/details/51473538
如下为这次的操作步骤：
mysql1：192.168.1.41 --已经存在的集群节点
mysql2：192.168.1.42 --将要加入的集群节点
1：启动mysql1，使用xtrabackup备份mysql1，并在mysql2上恢复

找出Xid的位置：
方法一：查看文件xtrabackup_galera_info
[root@mysql2 2016-06-25_21-30-21]# cat xtrabackup_galera_info
6a244048-3a0e-11e6-9016-831e882dea43:16
方法二：通过binlog位置来查找
[root@mysql2 2016-06-25_21-30-21]# cat xtrabackup_binlog_info
mysql-bin.000002 120
即备份时的备份点位置为log_bin.000002 120
再去Mysql1查找此binlog对应的xid：
[root@mysql1 bin]# cd /mysql/logs/
[root@mysql1 logs]# /usr/local/mysql/bin/mysqlbinlog -vv mysql-bin.000002 |grep Xid
#160625 21:34:40 server id 213306 end_log_pos 317 CRC32 0xa3386f6d Xid = 17
由于120是每个binlog开始的pos位，把Xid设为16.
在Mysql2上伪造一个grastate.dat文件（从Mysql1上复制过来，更改下seqno即可）：
[root@mysql2 data]# cat grastate.dat
# GALERA saved state
version: 2.1
uuid: 6a244048-3a0e-11e6-9016-831e882dea43

成功用IST来恢复了。
可以拿这里的error.log，与正常添加节点的error.log，进行比较，这里省略。
登录mysql2，查看数据是否正常：
[root@mysql2 mysql]# /usr/local/mysql/bin/mysql -S /tmp/mysql3306.sock

发现数据也已经全部同步完成。
pxc环境下避免新节点加入时需要进行SST的方法，在数据量大时SST将会占用大量的资源，
配置的gcache.size足够容纳从备份到恢复此时间段内主节点产生的数据量，建议通过业务
低峰期时通过脚本来实现此新节点加入操作。
