Şöyle bir çıktı verdi.
-------- Recommendations -----------------------------------------------------
General recommendations:
Run OPTIMIZE TABLE to defragment tables for better performance
MySQL started within last 24 hours - recommendations may be inaccurate
Reduce your overall MySQL memory footprint for system stability
Enable the slow query log to troubleshoot bad queries
Adjust your join queries to always utilize indexes
Set thread_cache_size to 4 as a starting value
Increase table_cache gradually to avoid file descriptor limits
Variables to adjust:
*** MySQL's maximum memory usage is dangerously high ***
*** Add RAM before increasing MySQL buffer variables ***
query_cache_size (>= 8M)
join_buffer_size (> 128.0K, or always use indexes with joins)
thread_cache_size (start at 4)
table_cache (> 64)
innodb_buffer_pool_size (>= 63M)


Bunun üzerine nano /etc/my.cnf komutu ile my.cnf içine
query_cache_size = 8M
join_buffer_size = 128.0K
thread_cache_size = 4
table_cache = 64
innodb_buffer_pool_size = 63M

komutlarını girdim.
