centos mysql5.6优化 innodb使用MYISAM存储引擎 

找到 /etc/my.cnf配置如下：

[mysqld]

performance_schema_max_table_instances=200

table_definition_cache=200

table_open_cache=128

innodb=OFF

default-storage-engine=MYISAM

default-tmp-storage-engine=MYISAM

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
