下面小編就為大家帶來一篇MySQL PXC建構一個新節點只需IST傳輸的方法(推薦)。小編的挺不錯的，現在就分享給大家，也給大家做個參考。一起跟著小編過來看看吧
需求場景：原有的pxc環境資料量已經比較大，新買的伺服器要加入此叢集中，如何讓其用IST的方式傳輸，而不是SST .
PXC傳輸資料有兩種方式：
IST：Incremental State Transfer 增量同步
SST：State Snapshot Transfer 全量同步
IST 發生的條件：This is done using caching mechanism on nodes （即只發生在先前叢集裡的節點資料還有在快取中）
判斷方法：
mysql> show global status like 'wsrep_local_cached_downto'; +---------------------------+-------+ | Variable_name | Value | +---------------------------+-------+ | wsrep_local_cached_downto | 1 | +---------------------------+-------+ 1 row in set (0.00 sec)
此值小於新開節點的seqno：
[root@zejin241 I6000]# cat grastate.dat # GALERA saved state version: 2.1 uuid: 6c86dc17-246f-11e6-9955-ae4d7e89eed2 seqno: 4 cert_index:
所以我們的思路即透過備份一個叢集中節點的數據，恢復到新節點上，並偽造一個grastate.dat，來記錄備份資料的seqno,這樣當新節點啟動時就會自動用IST的方法來進行，而不是SST（注意gcache.size應該有足夠的容量來確保在備份及恢復這段時間內新產生的資料都會被快取到）
galera.cache: This file is used as a main writeset store. It's implemented as a permanent ring-buffer file that is preallocated on disk when the node is initialized. File size can be controlled with the variable gcache.size. If this value is bigger, more writesets are cached and chances are better that the rejoining node will get IST instead of SST. Filename can be changed with the gcache.name variable.
#如下為這次的操作步驟：
#node240：192.168.1.240 --已經存在的叢集節點
node241：192.168.1.241 --將要加入的叢集節點
step1：啟動新的叢集中的第一個節點
/usr/local/pxc_56/bin/mysqld_safe --defaults-file=/home/mysql/pxc6000.cnf --ledir=/usr/local/pxc_56/ bin/ --wsrep-new-cluster &
設定檔如下：
