3 copy以及chown
PS：磁盤空間不足，所以不能執(zhí)行copyback，直接MV了。
mv /home/alldb/* /data/xxxx/open/?
chown -R mysql.mysql /data/xxxx/open/


4 啟動 service mysqld start
用5.5.20的mysql啟動報錯如下：

5 google很久，看到說mysql升級到5.5的時候也報but the only supported page size in this release is=16384的錯誤，
于是就找原來版本5.1的安裝目錄，用mysqld_safe啟動，ok，搞定
sudo /usr/local/mysql-5.1.56/bin/mysqld_safe --basedir=/usr/local/mysql-5.1.56/ --datadir=/data/md/open --user=mysql &


6 mysql 登錄正常,驗證slave：
