升级my.cnf注意
mkdir -p /ngbs/data/{logs,tmp}
vi /etc/init.d/mysql
basedir=/usr/local/mysql
datadir=/ngbs/data/
cp ib_logfile* logs/
chown -R mysql:mysql /ngbs/data
要注意ibdata1大小要跟实际大小一样
不然报错
2017-04-14 18:14:13 16812 [ERROR] InnoDB: auto-extending data file /ngbs/data/ibdata1 is of a different size 25344 pages (rounded down to MB) than specified in the .cnf file: initial 64000 pages, max 0 (relevant if non-zero) pages!
2017-04-14 18:14:13 16812 [ERROR] InnoDB: Could not open or create the system tablespace. If you tried to add new data files to the system tablespace, and it failed here, you should now edit innodb_data_file_path in my.cnf back to what it was, and remove the new ibdata files InnoDB created in this failed attempt. InnoDB only wrote those files full of zeros, but did not yet use them in any way. But be careful: do not remove old data files which contain your precious data!
