一、确定版本

查看MySQL版本
复制代码 代码如下:mysql -V
或者可以登录MySQL使用select version();或status;命令查看

二、开始工作

关闭MySQL
复制代码 代码如下:
service mysql stop
如果上面的命令无法关闭MySQL，则使用kill -9命令强制杀掉进程；

修改MySQL配置文件my.cnf（通常位于/etc/mysql/my.cnf）下加入如下字段

对于MySQL 5.5而言：

复制代码 代码如下:
default-storage-engine=MyISAM
loose-skip-innodb

loose-innodb-trx=0
loose-innodb-locks=0
loose-innodb-lock-waits=0
loose-innodb-cmp=0
loose-innodb-cmp-per-index=0
loose-innodb-cmp-per-index-reset=0
loose-innodb-cmp-reset=0
loose-innodb-cmpmem=0
loose-innodb-cmpmem-reset=0
loose-innodb-buffer-page=0
loose-innodb-buffer-page-lru=0
loose-innodb-buffer-pool-stats=0
对于MySQL 5.6而言：
复制代码 代码如下:
default-storage-engine=MyISAM
default-tmp-storage-engine=MYISAM
loose-skip-innodb

loose-innodb-trx=0
loose-innodb-locks=0
loose-innodb-lock-waits=0
loose-innodb-cmp=0
loose-innodb-cmp-per-index=0
loose-innodb-cmp-per-index-reset=0
loose-innodb-cmp-reset=0
loose-innodb-cmpmem=0
loose-innodb-cmpmem-reset=0
loose-innodb-buffer-page=0
loose-innodb-buffer-page-lru=0
loose-innodb-buffer-pool-stats=0
loose-innodb-metrics=0
loose-innodb-ft-default-stopword=0
loose-innodb-ft-inserted=0
loose-innodb-ft-deleted=0
loose-innodb-ft-being-deleted=0
loose-innodb-ft-config=0
loose-innodb-ft-index-cache=0
loose-innodb-ft-index-table=0
loose-innodb-sys-tables=0
loose-innodb-sys-tablestats=0
loose-innodb-sys-indexes=0
loose-innodb-sys-columns=0
loose-innodb-sys-fields=0
loose-innodb-sys-foreign=0
loose-innodb-sys-foreign-cols=0

三、查看成效

登录MySQL
复制代码 代码如下:mysql -uroot -p你的密码
显示使用的数据库引擎
复制代码 代码如下:
