從mysqltuner報告,你能幫我嗎?如何禁用InnoDB ist最後的Linux debian mysql版本穩定,並且連接中斷超過30%?Mysqltuner優化配置和表,報告

[!!] InnoDB is enabled but isn't being used 
[OK] Total fragmented tables: 0 

-------- Performance Metrics ------------------------------------------------- 
[--] Up for: 13h 49m 59s (18K q [0.368 qps], 2K conn, TX: 5M, RX: 1M) 
[--] Reads/Writes: 63%/37% 
[--] Total buffers: 176.0M global + 2.7M per thread (25 max threads) 
[OK] Maximum possible memory usage: 243.2M (23% of installed RAM) 
[!!] Slow queries: 7% (1K/18K) 
[OK] Highest usage of available connections: 20% (5/25) 
[OK] Key buffer size/total MyISAM indexes: 8.0M/185.0K 
[OK] Key buffer hit rate: 96.0% (27K cached/1K reads) 
[OK] Query cache efficiency: 41.0% (3K cached/8K selects) 
[OK] Query cache prunes per day: 0

[OK] Open file limit used: 9% (94/1K) 
[OK] Table locks acquired immediately: 99% (9K immediate/9K locks) 
[!!] Connections aborted: 32% 

-------- Recommendations ----------------------------------------------------- 
General recommendations: 
    Add skip-innodb to MySQL configuration to disable InnoDB 
    MySQL started within last 24 hours - recommendations may be inaccurate 
    Increase table_open_cache gradually to avoid file descriptor limits 
    Read this before increasing table_open_cache over 64: http://bit.ly/1mi7c4C 
    Your applications are not closing MySQL connections properly 
Variables to adjust: 
    table_open_cache (> 64)
