mysqltuner result help/info Table cache hit rate: 0%

hello ! i've read rthe forum and see the mysql video but not understand very well....

can i ask if my.cnf is ok for my server ? i've shared hosting server 6gb ram 6vcpu xeon e5504 2.2ghz

this is my.cnf

Code:

root@cp1 [/usr/local/cpanel/3rdparty/mysqltuner]# cat /etc/my.cnf
[mysqld]
set-variable = max_connections=200
query_cache_type=1
query_cache_size=64M
query_cache_limit=1M
sort_buffer_size=2M
read_rnd_buffer_size=512K
tmp_table_size=64M
max_heap_table_size=64M
thread_cache_size=24
key_buffer_size=16M
table_cache=192
join_buffer_size=2M
log-slow-queries=/var/lib/mysql/slow.log
innodb_buffer_pool_size=80M
innodb_file_per_table=1
open_files_limit=13460
max_allowed_packet=128M

and this the result of mysql tuner

-------- Recommendations -----------------------------------------------------
General recommendations:
    Run OPTIMIZE TABLE to defragment tables for better performance
    Adjust your join queries to always utilize indexes
    When making adjustments, make tmp_table_size/max_heap_table_size equal
    Reduce your SELECT DISTINCT queries without LIMIT clauses
    Increase table_cache gradually to avoid file descriptor limits
Variables to adjust:
    query_cache_size (> 64M)
    join_buffer_size (> 2.0M, or always use indexes with joins)
    tmp_table_size (> 64M)
    max_heap_table_size (> 64M)
    table_cache (> 192)

yesterday i've adjust setting but the result are the same... can i modyfy add or delete something ??

thanks

 

hello thinkbot,

first of all thank you very much for the quick response.

the code you have posted is to replace the mine to give to make a test?

the pt-query-digest is a tool to test the slow query ?
